This version favors completeness over pacing. Use it when you need the appendix, the dense source trail, or the full long-form reference in one place.

Best reading order

  1. Use the fast-answer and official-links sections first if you only need the main route and source trail.
  2. Open the entity, setup, tax, and local sections only where your exact launch path actually branches.
  3. Use the full source directory last as the appendix, not the starting point, unless you already know the exact agency task.

Start here Fast answer If you want to open Amazon FBA in Missouri, you usually need to do five things in order: Everyone 5 steps

If you want to open Amazon FBA in Missouri, you usually need to do five things in order:

  1. Choose your setup: sole proprietorship vs single-member LLC.
  2. Get your federal and Missouri registrations in place before launching.
  3. Verify local county or city permit, zoning, and home-business rules.
  4. Open and verify your Amazon FBA account or storefront.
  5. Launch only after your product, fulfillment, tax, and compliance setup is ready.

Practical first-launch recommendation

If you are testing casually with minimal risk, sole proprietor can work.

If you intend to build a real Amazon FBA business, single-member LLC is usually the better long-term path.

Avoid these first-launch mistakes

  • Buying inventory or launching before checking legal and platform restrictions
  • Using a DBA or brand name without filing the right Missouri fictitious-name document or local license paperwork
  • Mixing personal and business money

Missouri-specific friction

Missouri does not give beginners one perfectly clean marketplace-tax answer. The Department of Revenue says a marketplace seller selling only through a marketplace facilitator does not have to register, collect, or remit vendor's use tax. But the same Department's business-registration guidance also says a business making taxable retail sales from a location in Missouri must obtain a sales tax license. If you are a Missouri-based Amazon-only seller, do not guess your way through that split. Confirm with DOR before treating Amazon marketplace collection as a full substitute for Missouri registration.

If you are a Missouri-based Amazon-only seller, do not guess your way through that split. Confirm with DOR before treating Amazon marketplace collection as a full substitute for Missouri registration.
  • Form 149 is real and useful, but it is not a magic substitute for the rest of your Missouri setup. Missouri's public resale materials say Missouri retailers must have a Missouri Tax I.D. Number for purchases of tangible personal property for resale, while 100% wholesale sellers can avoid a retail sales tax license. A normal Amazon FBA seller buying inventory for retail resale should resolve the retail-license question first, then use Form 149 as the resale document that fits that registration posture.
  • Missouri local tax sourcing is more awkward than many founders expect. The DOR's local-tax rule says Missouri local sales tax generally follows the seller's Missouri place of business, while local use tax generally follows where the item is first delivered in Missouri. That matters as soon as you add non-Missouri inventory, direct orders, or other channels alongside Amazon.
  • A Missouri LLC does not file an annual report with the Secretary of State, but that does not mean the business is maintenance-free. Your real recurring obligations can still include sales-tax returns, Form 126 updates when locations or addresses change, local license renewals, and fictitious-name renewal every 5 years if you are using a DBA.

Amazon FBA-specific friction

Amazon account verification is document-driven. As of April 27, 2026, Amazon's public seller-registration guide still shows the five-step registration flow and says identity verification usually takes three business days or less, but delays are common when bank, address, and entity records do not match. For a Missouri seller, misalignment between SOS, DOR, banking, and Amazon records is one of the fastest ways to create avoidable launch friction.

For a Missouri seller, misalignment between SOS, DOR, banking, and Amazon records is one of the fastest ways to create avoidable launch friction.
  • FBA solves fulfillment, not licensing or tax classification. Amazon can store, pick, pack, ship, handle customer service, and process returns, but it does not decide whether your Missouri retail-sales-license branch, resale-certificate branch, or Kansas City local-license branch applies.
  • Amazon category, approval, and dangerous-goods rules can block a launch even when the Missouri side is clean. Keep the first product simple so you are not solving FBA prep, hazmat, restricted-category, and Missouri setup problems at the same time.

Insurance reality

If you are selling physical products, treat commercial general liability and product-liability coverage as an operating control, not just an Amazon checkbox. FBA does not eliminate your exposure if a product allegedly injures a customer, damages property, or triggers a claim chain through your listings.

FBA does not eliminate your exposure if a product allegedly injures a customer, damages property, or triggers a claim chain through your listings.
  • As of April 27, 2026, an Amazon-owned public Seller Forums post says Section 9 of the Amazon Services Business Solutions Agreement requires commercial liability insurance within 30 days after exceeding USD 10,000 in gross proceeds in one month on Amazon.com, or earlier if Amazon requests it.
  • That same Amazon-owned public post says the policy generally must be at least USD 1 million per occurrence and in aggregate, cover all listed products, keep any deductible at USD 10,000 or less, and name Amazon.com Services LLC and its affiliates and assignees as additional insureds.
  • Important caveat: the controlling agreement language lives inside Seller Central and is partly login-gated. Use the public forum post as a warning signal, then re-check the live Seller Central agreement before relying on the threshold, deductible, naming, or enforcement details.
Back to top Next: Quick-start checklist
Checklist Quick-start checklist Use the research-backed checklist groups before you spend, before your first sale, and before launch goes live. Everyone 3 groups

Do these before you spend money

  • Pick your entity.
  • Pick your business name.
  • Decide your product or service lane.
  • Avoid regulated or high-risk categories for your first launch unless the request specifically wants them.
  • Confirm the offer is not blocked by law, safety rules, or platform policy.
  • Make sure you can document sourcing, licensing, or supplier legitimacy where relevant.

Do these before your first sale

  • Form the business or file your DBA if needed.
  • Get an EIN from the IRS if applicable.
  • Open a dedicated business bank account.
  • Register for Missouri tax or seller permits that apply.
  • Check local permits and home-based business rules.
  • Create your Amazon FBA account and complete verification.

Do these before launch goes live

  • Complete the platform setup branch.
  • Confirm product, category, or account eligibility.
  • Set up fulfillment, shipping, inventory, or storefront operations correctly.
  • Build the first listing, store pages, or checkout flow correctly.
  • Start small so you can test demand and catch compliance mistakes early.
Back to top Next: Official links you will use first
Choose your setup Entity choice Compare the sole-proprietor and single-member LLC paths before banking, tax setup, and platform onboarding. Everyone 2 options

Sole proprietor

Best for: Best if you want the cheapest and simplest start.

What it means

  • No Missouri Secretary of State creation filing is required just to exist as a sole proprietor operating under your true legal name.
  • If you want to use a public-facing name that is not your true legal name, Missouri uses a statewide fictitious name filing with the Secretary of State, not a county-only DBA filing. The public filing fee is USD 7, the registration lasts 5 years, and it does not give exclusive rights to the name.
  • Business income generally runs through your personal federal and Missouri individual tax returns unless facts change the tax treatment.
  • You usually do not get a liability shield.

Why someone chooses it

  • Faster launch
  • Lower up-front filing costs
  • Fewer entity maintenance steps

Main downside: Personal liability

single-member LLC

Best for: Best if you want a more durable setup for a real business.

What it means

  • File Articles of Organization (LLC-1) with the Missouri Secretary of State, choose whether the company is member-managed or manager-managed, and appoint a Missouri registered agent with a physical Missouri address. The current public filing fee is USD 50 online or USD 105 by paper.
  • Keep the operating agreement internally after formation. Missouri's current public LLC materials reviewed on April 27, 2026 do not identify a default LLC annual report. Ongoing Missouri public maintenance in this packet is mostly event-driven change filings plus fictitious name renewal every 5 years if you use a DBA.
  • For federal income tax, a single-member LLC is usually a disregarded entity unless you elect corporation treatment. Missouri still treats sales-tax, withholding, local-license, and any corporate-income-tax branch as separate registrations from the legal formation filing.

Why someone chooses it

  • Liability protection
  • Cleaner setup for banking, vendors, bookkeeping, and scaling
  • Better fit for trademarks, insurance, employees, and later restructuring

Main downside: Higher setup friction and cost than a sole proprietorship

Back to top Next: What to do in order
Main path What to do in order The full end-to-end setup path, kept in the same order as the researched guide. Everyone 14 steps

  1. Step 1: Choose a low-risk launch model

    Main guide step 1

    For a first launch, stay inside the safest lane:

    Why it matters: Practical rule: If the offer touches health, safety, children, regulated finance, chemicals, alcohol, medical claims, or restricted IP, slow down and do category-specific compliance research before buying or launching.

    • general merchandise
    • no high-risk categories from food, supplements, cosmetics, medical claims, batteries-heavy hazmat, alcohol, children's products
    • no products or offers that require specialized compliance unless the guide is explicitly built for them

  2. Step 2: Choose your name and brand approach

    Main guide step 2

    You need to decide whether you are:

    Why it matters: Important:

    • operating under your own legal name,
    • using a trade name or DBA,
    • reselling existing brands,
    • creating your own brand,
    • or using a private-label or DTC brand path.
    • Platform-facing store names do not always need to match the legal entity name, but the registration details must still match real-world documents.
    • If you want strong long-term control, build your trademark and brand documentation path early.

  3. Step 3: Form the business

    Main guide step 3

    If you choose sole proprietor: If you operate under your true legal name, no Missouri Secretary of State creation filing was verified for the sole proprietorship itself.

    • If you choose sole proprietor: If you operate under your true legal name, no Missouri Secretary of State creation filing was verified for the sole proprietorship itself.
    • If you choose sole proprietor: If you want a different public business name, file the Missouri fictitious name registration with the Secretary of State before you start using that name with suppliers, banks, or Amazon.
    • If you choose sole proprietor: Keep the local branch separate. A fictitious name filing does not replace Missouri tax registration, Kansas City licensing, or local zoning review.
    • If you choose single-member LLC: Do this in order:
    • If you choose single-member LLC: Check Missouri name availability before filing. If you need to hold the name first, Missouri allows a 60-day name reservation with up to two additional 60-day renewals.
    • If you choose single-member LLC: File Articles of Organization (LLC-1) with the Missouri Secretary of State. The current public fee is USD 50 online or USD 105 by paper.
    • If you choose single-member LLC: Adopt the operating agreement as an internal document immediately after formation. Missouri's public LLC materials reviewed for this packet did not identify a publication step or initial report.
    • If you choose single-member LLC: If the public brand will differ from the legal LLC name, file the separate Missouri fictitious name registration with the Secretary of State.

  4. Step 4: Get your EIN

    Main guide step 4

    Use the IRS EIN application if applicable. For many LLCs this is required. For many sole proprietors it is optional but still useful for banking, vendors, and platform setup.

  5. Step 5: Open banking and bookkeeping

    Main guide step 5

    Do this right away:

    • Open a business checking account.
    • Use one account and one card for business only.
    • Save every receipt, invoice, shipping bill, platform fee statement, and tax record.
    • Build a tax folder and a compliance folder from day one.

  6. Step 6: Register for state tax, seller permit, or resale setup

    Main guide step 6

    Register with the Missouri Department of Revenue through the online registration system or Form 2643, Missouri Tax Registration Application.

    • Register with the Missouri Department of Revenue through the online registration system or Form 2643, Missouri Tax Registration Application.
    • If you are making retail sales of tangible personal property from a Missouri location, Missouri public guidance says you must obtain the sales-tax-license branch before making sales.
    • Important Missouri split: the Department's marketplace-facilitator FAQ says a marketplace seller selling only through a marketplace facilitator does not have to register, collect, or remit vendor's use tax. That is not the same question as whether a Missouri-based seller making retail sales from a Missouri location needs the Missouri retail sales license branch. Resolve that conflict with DOR before launch instead of guessing.
    • If you buy inventory for resale, use Missouri Form 149, Sales and Use Tax Exemption Certificate, only after your Missouri tax-registration posture is clear. Missouri public guidance says 100% wholesale sellers do not need a retail sales tax license, but a normal retail Amazon FBA seller should not assume that exception applies.

  7. Step 7: Check local permits, county rules, and home-business limits

    Main guide step 7

    Missouri may not have one statewide local-business form for every county or city.

    Why it matters: Do this before operating:

    • check the state business portal,
    • do not assume a county DBA filing exists for the business name branch because Missouri uses a statewide fictitious name filing,
    • contact the city, town, or village office where you will operate,
    • ask about zoning, occupancy, and local permit rules.

  8. Step 8: If you hire employees, handle payroll registrations and insurance

    Main guide step 8

    If you do not hire anyone yet, skip this for now.

    Why it matters: If you hire:

    • Register the employer through Missouri's online business registration path and, if needed, the Division of Employment Security UInteract new-employer workflow.
    • Missouri workers' compensation coverage is generally required at 5 or more employees, or at 1 or more employees in the construction industry.
    • This packet did not identify a separate Missouri statewide private-employer disability-insurance or paid-family-leave registration branch on the official employer pages reviewed on April 27, 2026.
    • This packet also did not identify a broad Missouri CE-200-style exemption certificate for ordinary employers. If you are below the workers' compensation threshold, that is a legal threshold question, not a substitute certificate branch established in the reviewed public record.

  9. Step 9: Create your Amazon FBA account or store

    Main guide step 9

    Have these ready:

    Why it matters: Platform registration flow: Amazon's public registration guide reviewed on April 27, 2026 says the setup can often be completed in a few hours and identity verification usually takes three business days or less.

    • government-issued ID
    • phone number
    • email address
    • bank account information
    • tax information
    • business registration or license if required
    • proof of address or identity if the platform asks for it
    • Start the seller registration flow on sell.amazon.com.
    • Provide business information.
    • Provide seller and billing information.
    • Provide store and product information.
    • Complete identity verification.

  10. Step 10: Choose the right platform plan

    Main guide step 10

    Amazon's public pricing page reviewed on April 27, 2026 shows the Individual plan at $0.99 per item sold and the Professional plan at $39.99 per month, plus referral fees and any optional FBA or advertising costs.

    • Amazon's public pricing page reviewed on April 27, 2026 shows the Individual plan at $0.99 per item sold and the Professional plan at $39.99 per month, plus referral fees and any optional FBA or advertising costs.
    • Stay on Individual if you are testing lightly and want the lowest fixed cost. Move to Professional if you need the advanced seller toolset, expect meaningful volume, or want a cleaner long-term operating setup.

  11. Step 11: Decide whether brand or IP programs belong in the initial launch

    Main guide step 11

    Amazon Brand Registry is optional for a beginner resale launch.

    • Amazon Brand Registry is optional for a beginner resale launch.
    • It becomes more relevant if you are creating a private-label or house-brand catalog. Amazon's public Brand Registry page reviewed on April 27, 2026 says enrollment requires a pending or registered trademark plus brand name or logo permanently affixed to products or packaging.

  12. Step 12: Complete the fulfillment or operations branch

    Main guide step 12

    Use the platform-specific version of this section:

    • For Amazon FBA: register for FBA, confirm product eligibility, prep and label inventory, create shipment, send a small first batch.
    • For Shopify: create the store, configure payments, taxes, shipping, policies, domain, analytics, and fulfillment path.
    • For other channels: replace this section with the channel's actual onboarding and launch workflow.

  13. Step 13: Confirm product, service, or category eligibility before scaling

    Main guide step 13

    Check restricted products, gated categories, brand/IP risks, and dangerous-goods rules before you buy deep inventory.

    • Check restricted products, gated categories, brand/IP risks, and dangerous-goods rules before you buy deep inventory.
    • Amazon's public FAQ says some categories are open, some require approval, and some cannot be sold by third-party sellers.
    • Amazon's public dangerous-goods guidance says some products can require classification review plus a safety data sheet or exemption sheet before FBA use is allowed.
    • Keep invoices, supplier records, and authenticity evidence from day one. Do not treat a successful first shipment as proof that the category is permanently safe; re-check when the product, packaging, or chemistry changes.

  14. Step 14: Launch with a compliance-first operating routine

    Main guide step 14

    Once live, keep these habits:

    • reconcile payouts, fees, refunds, and reimbursements
    • monitor account health or store operations
    • maintain invoices and supplier records
    • keep tax reserves separate
    • avoid mixing personal and business spending
    • monitor margins, returns, and compliance issues

Best practical order for the LLC launch path

  1. Choose a low-risk product lane first so you are not mixing basic Missouri setup with restricted-category compliance.
  2. Choose the legal LLC name and decide whether you also need a separate Missouri fictitious name for the public brand.
  3. File the Missouri Articles of Organization, choose the registered agent, and keep the operating agreement internally because Missouri does not file it with the Secretary of State.
  4. Get the EIN and open the business bank account immediately after formation.
  5. Decide whether you will make any direct Missouri sales outside Amazon before buying inventory, because that answer changes the DOR registration branch.
  6. If you will make direct taxable Missouri sales, register with DOR through the online business-registration system or Form 2643 before launch.
  7. If you think you qualify to rely on the marketplace-only seller rule, get direct confirmation before acting on that assumption instead of treating Amazon collection as a universal Missouri exemption.
  8. Line up the resale-document branch only after the tax-registration posture is clear, and use Form 149 as the resale certificate that fits your real Missouri tax identity.
  9. Clear the local branch next. If you are in Kansas City, that means RD-100, zoning clearance, business-license setup, and any county business personal property receipt issue tied to the assets you keep there.
  10. Build the Amazon seller account only after the legal name, address, bank, and tax records are aligned across your source documents.
  11. Choose the selling plan, confirm category and FBA eligibility, and send a small first shipment.
  12. Track the real recurring items on your calendar: no Missouri LLC annual report, but sales-tax filing obligations, fictitious-name renewal if used, Form 126 changes when facts move, Kansas City renewals if applicable, and Amazon insurance re-checks as sales scale.

1. EIN

A single-member LLC generally needs an EIN.

  • A single-member LLC generally needs an EIN.
  • A sole proprietor may not always need one federally, but it is often the cleaner operational choice anyway.

2. Missouri sales tax, seller permit, or equivalent registration

Register through Missouri's online business-registration system or Form 2643, Missouri Tax Registration Application.

  • Register through Missouri's online business-registration system or Form 2643, Missouri Tax Registration Application.
  • Missouri DOR public guidance says a business making sales of tangible personal property from a location in Missouri must obtain the sales-tax-license branch before making sales.
  • DOR also uses the same registration system for employer withholding, unemployment-tax integration, corporate-income-tax registration, and related business tax accounts.

3. Marketplace or platform tax rule

Missouri's marketplace-facilitator FAQ says a marketplace seller selling only through a marketplace facilitator does not have to register, collect, or remit vendor's use tax.

  • Missouri's marketplace-facilitator FAQ says a marketplace seller selling only through a marketplace facilitator does not have to register, collect, or remit vendor's use tax.
  • That same public split does not fully answer the separate Missouri in-state retail-sales-license question for a Missouri-based seller making retail sales from a Missouri location.
  • If you also make independent non-marketplace sales into Missouri and your total gross receipts, including marketplace-facilitated sales, exceed USD 100,000, Missouri's public remote-seller guidance says the independent sales branch can trigger registration and collection duties.

4. Resale purchases or exempt purchasing

Use Missouri Form 149, Sales and Use Tax Exemption Certificate, when the purchase genuinely qualifies for resale or another covered exemption.

  • Use Missouri Form 149, Sales and Use Tax Exemption Certificate, when the purchase genuinely qualifies for resale or another covered exemption.
  • Missouri public guidance says a Missouri retailer needs a Missouri tax ID number to buy tangible personal property for resale, while a 100% wholesale seller does not need a retail sales tax license.
  • A normal Amazon retail seller should settle the Missouri tax-registration posture first and then use Form 149 in the way that matches that posture.

5. Entity tax treatment

A standard single-member LLC is usually disregarded for federal income-tax purposes unless it elects a different classification.

  • A standard single-member LLC is usually disregarded for federal income-tax purposes unless it elects a different classification.
  • Missouri's startup guidance says LLC income and losses generally flow through to the members rather than being taxed separately like a corporation.
  • Missouri still separates entity formation from business-tax registration, so sales tax, withholding, unemployment, and any corporate-income-tax branch are handled through the tax agencies rather than through the LLC filing itself.

6. Entity filing-fee or franchise-tax rule

This packet did not verify a general Missouri LLC franchise tax or annual report in the current public record reviewed on April 27, 2026.

  • This packet did not verify a general Missouri LLC franchise tax or annual report in the current public record reviewed on April 27, 2026.
  • The recurring public Missouri obligations identified here are DOR tax returns if you are registered, Form 126 updates when locations or addresses change, and fictitious name renewal if you use one.
  • If the business later elects corporate tax treatment or otherwise creates a Missouri corporate-income-tax branch, re-check that filing path directly with DOR.

7. If the founder changes entity type later

Treat a sole-proprietor-to-LLC conversion as a new-registration checkpoint.

  • Treat a sole-proprietor-to-LLC conversion as a new-registration checkpoint.
  • Missouri DOR public guidance says a new FEIN or new charter number will often trigger a new Missouri tax ID result, and Missouri labor guidance says a new owner or new legal entity generally completes a new unemployment-tax registration.
  • Do not assume the old sole-proprietor tax, payroll, or local-license posture carries over automatically to the new LLC.

Local branch Local permits and Kansas City branch These local and city checks can still change the answer even after the state and platform path is clear. Location-specific 2 branches

Local permits and location checks

Missouri does not use one statewide local business-license filing that makes city and county issues disappear. The Secretary of State's public FAQ says many municipalities and counties require businesses to obtain a local business license before opening, and that those licenses come from the local government rather than from the Secretary of State.

  • Missouri does not use one statewide local business-license filing that makes city and county issues disappear. The Secretary of State's public FAQ says many municipalities and counties require businesses to obtain a local business license before opening, and that those licenses come from the local government rather than from the Secretary of State.
  • For any place where the business will operate:
  • start with the city or municipal business-license office, not with a county assumed-name filing theory, because Missouri DBAs are handled through the statewide fictitious-name registration system,
  • check the local zoning or planning office if the business will operate from home, store inventory, receive frequent carrier pickups, or use business vehicles at the address,
  • check building or occupancy staff if the business activity could change the official occupancy or life-safety demands of the property,
  • ask whether a local license renewal will require state tax proof, a county business personal property tax receipt, or both.
  • Typical local risk areas:
  • city business license
  • zoning clearance or occupancy clearance
  • home occupation restrictions
  • inventory storage
  • truck or carrier activity at a residence
  • fire-code or life-safety limits
  • county administration of business personal property taxes for local-license support when assets are located there

Kansas City Appendix

  • If the business operates in Kansas City, add one more review layer.
  • Kansas City, Missouri has a real local-license and local-tax stack. The City's finance FAQ says all businesses operating in Kansas City, Missouri must have a business license, regardless of size or type, and the City's business-license search page says licenses expire on December 31 each year.
  • For new businesses, the City's tax-forms page uses Form RD-100 as the registration application, and the annual business-license filings run through Form RD-105 or Form RD-103 depending on the business activity. The City's tax-forms page also says that as of January 1, 2025, all KCMO taxes must be filed electronically through Quick Tax.
  • The City's business-license page says a seller with retail sales inside Kansas City, Missouri needs a Missouri sales tax number from the Missouri Department of Revenue. The same page says a business personal property tax receipt is required for business vehicles, business property, or other business assets, and that the relevant county handles those receipts.
  • Zoning is its own gate. The City's zoning-verification page says zoning clearance is an essential step for issuing a business license to businesses located in Kansas City, and that zoning approval does not itself confirm the correct building-code occupancy.
  • Kansas City also has local earnings and profits tax exposure. The City's earnings-tax page says the earnings tax is 1 percent and applies to residents, people who work in the city, and the net profits of businesses. The City's tax-forms page says Form RD-108/108B is used by a sole proprietor, corporation, partnership, or other fiduciary to file and pay the 1 percent tax on net profits, and that the form is required even if there is a loss.
  • Home-based businesses need extra caution. Current KCMO finance pages broadly say all businesses operating in the city need a business license and that businesses with employees working from a home office in Kansas City can trigger local profits tax, earnings-tax withholding, and business licensing. But an April 2026 City Planning and Development presentation says Missouri House Bill 2593 forbids cities from requiring licensing or permits for qualifying no-impact home-based businesses. Because those public signals are not yet harmonized on the City's outward-facing pages, confirm the home-business branch directly with KC BizCare, zoning staff, and the Business License Section before relying on an exemption.

Optional branch Employees and insurance Use this branch if you plan to hire or need the insurance follow-up that comes with scaling. Only if hiring or scaling 5 branches

1. Employer registration

Missouri uses the online business-registration system and the Division of Employment Security UInteract path for new-employer setup.

  • Missouri uses the online business-registration system and the Division of Employment Security UInteract path for new-employer setup.
  • For a normal Missouri small business, the employer-registration agencies in this packet are the Department of Revenue for withholding and the Division of Employment Security for unemployment tax.
  • Missouri labor guidance also says employers must report wages quarterly and report newly hired employees.

2. Workers' compensation

Missouri requires workers' compensation insurance if you have 5 or more employees, unless you are in the construction industry, where the threshold is 1 or more employees.

  • Missouri requires workers' compensation insurance if you have 5 or more employees, unless you are in the construction industry, where the threshold is 1 or more employees.
  • Missouri workers' compensation coverage is generally required at 5 or more employees, or at 1 or more employees in the construction industry.
  • This packet also did not identify a broad Missouri CE-200-style exemption certificate for ordinary employers. If you are below the workers' compensation threshold, that is a legal threshold question, not a substitute certificate branch established in the reviewed public record.

3. Disability, paid leave, or similar coverage

No separate Missouri statewide private-employer disability-insurance or paid-family-leave registration branch was verified on the official employer pages reviewed for this packet on April 27, 2026.

  • No separate Missouri statewide private-employer disability-insurance or paid-family-leave registration branch was verified on the official employer pages reviewed for this packet on April 27, 2026.

4. Exemption certificate if applicable

  • If you are below the statutory workers' compensation threshold, that is a threshold analysis, not a separate statewide exemption-certificate path established in the reviewed public record.

Insurance reality

If you are selling physical products, treat commercial general liability and product-liability coverage as an operating control, not just an Amazon checkbox. FBA does not eliminate your exposure if a product allegedly injures a customer, damages property, or triggers a claim chain through your listings.

  • If you are selling physical products, treat commercial general liability and product-liability coverage as an operating control, not just an Amazon checkbox. FBA does not eliminate your exposure if a product allegedly injures a customer, damages property, or triggers a claim chain through your listings.
  • As of April 27, 2026, an Amazon-owned public Seller Forums post says Section 9 of the Amazon Services Business Solutions Agreement requires commercial liability insurance within 30 days after exceeding USD 10,000 in gross proceeds in one month on Amazon.com, or earlier if Amazon requests it.
  • That same Amazon-owned public post says the policy generally must be at least USD 1 million per occurrence and in aggregate, cover all listed products, keep any deductible at USD 10,000 or less, and name Amazon.com Services LLC and its affiliates and assignees as additional insureds.
  • Important caveat: the controlling agreement language lives inside Seller Central and is partly login-gated. Use the public forum post as a warning signal, then re-check the live Seller Central agreement before relying on the threshold, deductible, naming, or enforcement details.

Before first sale

  • Finish entity or DBA setup.
  • Get EIN if applicable.
  • Open bank account.
  • If you will make retail sales from a Missouri location, register through Missouri's online business-registration system or Form 2643 before sales.
  • If you plan to rely on the marketplace-only seller rule instead of registering, confirm that posture with Missouri DOR before launch rather than assuming Amazon collection answers the Missouri in-state retailer rule for you.
  • If you need resale paperwork for supplier purchases, make sure your Form 149 path matches your actual Missouri tax-registration posture.
  • Check city and county branches that actually apply, especially Kansas City zoning, business-license, and property-tax-receipt requirements if the business is based there.
  • Complete platform verification.

Before first live launch

  • Finish the FBA operations branch.
  • Confirm product, category, and FBA eligibility.
  • Build accurate listings, store pages, or policies.
  • Complete prep, labeling, and your first inbound shipment setup.
  • Keep invoices, supplier records, and tax documents together before the first box goes to Amazon.

Monthly

  • Reconcile payouts, fees, refunds, and reimbursements.
  • Review cash reserves for taxes.
  • Review margins, inventory age, or shipping performance.
  • Check account health, store errors, or suppressed listings.
  • If Missouri assigned you monthly sales or use tax filing, the return is due on or before the last day of the following month.

Quarterly

  • If Missouri assigned you quarterly sales or use tax filing, the return is due on or before the last day of the month following the end of the quarter.
  • If you hold a Missouri sales-tax license, file the return even when sales are zero for the period.
  • If you have scaled into large Missouri tax collections, watch the quarter-monthly trigger. Missouri requires quarter-monthly sales-tax payments when average monthly Missouri state sales tax equals or exceeds USD 15,000 during at least 6 of the previous 12 months.

Annual or periodic

  • There is no Missouri LLC annual report to file with the Secretary of State, so do not invent one on your calendar.
  • If you use a Missouri fictitious name, renewal belongs in the six-month window before expiration; the registration itself lasts 5 years.
  • If Missouri assigned you annual sales or use tax filing, the return is due on or before January 31 of the following year.
  • Use Form 126 when you need to add or close Missouri tax locations or update business, mailing, or owner address information with DOR.
  • In Kansas City, business licenses are valid through December 31, renewal is due by the last day of February, and fees are not prorated.
  • Re-check your insurance branch before or immediately after any month that could put you over Amazon's public USD 10,000 one-month threshold, and again whenever you expand into riskier products.

Avoid these Common mistakes These are the repeated beginner errors called out in the research pack. Everyone 8 mistakes

Common Mistakes New Operators Make

  • Buying inventory or launching before checking legal and platform restrictions
  • Using a DBA or brand name without filing the right Missouri fictitious-name document or local license paperwork
  • Mixing personal and business money
  • Skipping tax registration because "the platform handles tax"
  • Launching with regulated products too early
  • Keeping weak supplier or compliance documentation
  • Missing state maintenance filings
  • Treating the platform as the compliance department

Practical first-launch recommendation

If you are testing casually with minimal risk, sole proprietor can work.

If you intend to build a real Amazon FBA business, single-member LLC is usually the better long-term path.
