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 California, you usually need to do five things in order: Everyone 5 steps

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

  1. Choose your setup: sole proprietorship vs single-member LLC.
  2. Get your federal and California registrations in place before launch.
  3. Verify county and city permit, zoning, and home-business rules.
  4. Open and verify your Amazon seller account, then set up FBA.
  5. Launch only after your product, fulfillment, tax, and documentation 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, a single-member LLC is usually the better long-term path in California because inventory, platform risk, and city compliance issues add up quickly.

Avoid these first-launch mistakes

  • Buying inventory before checking Amazon category and FBA eligibility
  • Treating Amazon marketplace collection as a complete answer to California tax registration
  • Using a brand or DBA before finishing the county filing branch

California-specific friction

California LLCs have a real recurring tax burden even before the business becomes large.

  • California LLCs have a real recurring tax burden even before the business becomes large.
  • California pushes name filings and many operating questions down to counties and cities.
  • The marketplace-seller carveout is useful, but it does not answer every direct-sales fact pattern for you.
  • Los Angeles adds a separate city layer if you operate there.

Amazon FBA-specific friction

Amazon category approval, FBA eligibility, and documentation requirements can block a product even after you have formed the business.

  • Amazon category approval, FBA eligibility, and documentation requirements can block a product even after you have formed the business.
  • Amazon account verification and review holds can slow launch timing.
  • FBA storage, prep, and inbound mistakes create costly avoidable errors.
  • Insurance rules are partly operationally important but not fully clean from public sources because the live agreement is login-gated.

Insurance reality

Physical-product sellers should plan around commercial general liability and product liability, even before Amazon formally forces the issue.

  • Physical-product sellers should plan around commercial general liability and product liability, even before Amazon formally forces the issue.
  • Public Amazon forum materials say commercial liability insurance may be required within 30 days after exceeding USD 10,000 in gross proceeds in one month, or earlier if Amazon requests it.
  • The live agreement and full insurance workflow are still login-gated in Seller Central, so re-check the live wording on the launch date before acting.
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 whether you are selling under your legal name, a county FBN/DBA, or a brand.
  • Stay in low-risk general merchandise for the first launch.
  • Avoid regulated categories such as food, supplements, cosmetics, medical-claim products, alcohol, heavy hazmat, and children's products unless you are doing separate category research.
  • Make sure you can document sourcing with invoices and supplier records.

Do these before your first sale

  • Form the business or file your county FBN if needed.
  • Get an EIN from the IRS if applicable.
  • Open a dedicated business bank account.
  • Run the California CDTFA analysis before assuming you do or do not need a seller's permit.
  • Check county and city permit rules, including Los Angeles business-tax and home-occupation rules if you will operate there.
  • Create your Amazon account and complete identity verification.

Do these before launch goes live

  • Complete the Amazon account setup branch.
  • Confirm the product is allowed on Amazon and eligible for FBA.
  • Set up prep, labeling, inbound shipping, and recordkeeping.
  • Send a small first batch instead of a large speculative shipment.
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

  • California does not require a California Secretary of State formation filing for a sole proprietorship.
  • If you use a name other than your legal name, a fictitious business name filing is handled with the county where the principal place of business is located.
  • Business income generally runs through your personal return.
  • You usually do not get a liability shield.

Why someone chooses it

  • Faster launch
  • Lower up-front cost
  • 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

  • California LLC formation uses Articles of Organization (Form LLC-1) with a $70 filing fee, plus an optional $5 certified copy charge if you request one.
  • California also requires a Statement of Information (Form LLC-12) within 90 days after registration and then every 2 years, with a $20 filing fee.
  • California imposes a recurring $800 annual LLC tax and may impose an additional LLC fee when California income reaches the statutory thresholds.

Why someone chooses it

  • Liability protection
  • Cleaner setup for banking, vendors, bookkeeping, insurance, and scaling
  • Better fit for wholesale sourcing, trademarks, and eventual hiring

Main downside: Higher cost and maintenance burden 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 product touches health, safety, children, chemicals, age restrictions, dangerous goods, or heavy IP risk, slow down and do product-specific compliance research before buying inventory.

    • general merchandise
    • no high-risk categories from food, supplements, cosmetics, medical claims, batteries-heavy hazmat, alcohol, children's products
    • no products that require specialized permits or compliance research

  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 county FBN/DBA,
    • reselling existing brands,
    • creating your own brand,
    • or building toward a private-label path.
    • Amazon says your store name does not have to match the legal business name, but your registration details must still match real documents.
    • If you want long-term brand control, start planning your trademark and Brand Registry path early.

  3. Step 3: Form the business

    Main guide step 3

    If you choose sole proprietor: No California Secretary of State formation filing is required.

    • If you choose sole proprietor: No California Secretary of State formation filing is required.
    • If you choose sole proprietor: If you use a trade name instead of your legal name, file the fictitious business name statement with the county where your principal place of business is located.
    • If you choose single-member LLC: Do this in order:
    • If you choose single-member LLC: Run a preliminary California name check and decide whether you need a reservation.
    • If you choose single-member LLC: File Articles of Organization (Form LLC-1) and pay the $70 filing fee. Add the optional $5 certified-copy fee only if you need that copy.
    • If you choose single-member LLC: File Statement of Information (Form LLC-12) within 90 days.
    • If you choose single-member LLC: If you will trade under a different business name, confirm the county FBN branch before using it.
    • If you choose single-member LLC: California caveat:
    • If you choose single-member LLC: The SOS pages clearly confirm online filing for LLC-1 and LLC-12. They do not give this pack a clean single answer on separate paper acceptance for LLC-1, so this draft treats paper acceptance as unverified and does not promise it.

  4. Step 4: Get your EIN

    Main guide step 4

    Use the IRS EIN application if applicable. For most LLCs this is effectively part of the normal setup. For many sole proprietors it is optional but still useful for banking, wholesale relationships, Amazon account support, and privacy.

  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 invoice, shipping bill, Amazon fee report, 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

    Amazon-specific tax reality:

    Why it matters: Do not assume "Amazon handles tax" means your California answer is finished. The marketplace-only carveout is narrow. The moment you add direct sales or another channel, your CDTFA registration answer may change.

    • California uses CDTFA for seller's permits and related registration paths.
    • If all of your California sales are marketplace sales facilitated by a registered marketplace facilitator, California says you are not required to register for a seller's permit or Certificate of Registration-Use Tax solely for those marketplace sales.
    • If you also make direct sales, wholesale sales, your own website sales, pop-up sales, or any other non-marketplace sales, do a separate CDTFA analysis before launch.
    • For resale purchases, CDTFA-230 can be used, but California also allows another document if it contains all required resale-certificate elements.

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

    Main guide step 7

    California does not have one statewide local-business form for every city or county.

    Why it matters: Do this before operating: Los Angeles branch: Los Angeles caveat: This pack does not claim there is one official Los Angeles page that gives a universal yes/no answer for every basic Amazon-FBA home-office setup. If you will store meaningful inventory, create repeated carrier traffic, or run prep operations from home, get local confirmation before launch.

    • check the state resources pages,
    • contact the county clerk if you need an FBN filing,
    • contact the city where you will operate,
    • ask about zoning, storage, deliveries, and local business-tax rules.
    • If you operate in the City of Los Angeles, a Business Tax Registration Certificate can apply.
    • Los Angeles says you are engaged in business when you physically perform work in the city for 7 or more days per year.
    • Home occupation limits include no exterior-visible business activity, no more than 1 nonresident employee, no more than 2 deliveries or pickups per day, and no storing commercial vehicles on site.

  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 with EDD within 15 days after paying more than $100 in wages in a calendar quarter.
    • Carry workers' compensation coverage because California requires it with 1 or more employees.
    • Expect payroll withholding and reporting duties through EDD once you become a subject employer.

  9. Step 9: Create your Amazon account

    Main guide step 9

    Have these ready:

    Why it matters: Platform registration flow: Amazon baseline note: As of April 26, 2026, Amazon still publicly says you do not have to be an LLC to open a selling account.

    • government-issued ID
    • phone number
    • email address
    • bank account information
    • tax information
    • business registration or license if applicable
    • proof of address from the last 180 days if Amazon asks
    • Enter business information.
    • Enter seller information.
    • Enter billing information.
    • Enter store and product information.
    • Complete identity verification.

  10. Step 10: Choose the right platform plan

    Main guide step 10

    Simple rule:

    Why it matters: If you expect to sell more than about 40 units per month or need more serious tools, start comparing against the Professional plan immediately.

    • As of April 26, 2026, Amazon's public pricing page shows Individual at $0.99 per item sold and Professional at $39.99 per month.
    • Referral fees are category-specific and additional FBA costs apply.
    • The Professional plan usually becomes worth it once you expect meaningful unit volume, need certain category access, or want the fuller seller toolset.

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

    Main guide step 11

    Brand Registry is optional at launch.

    • Brand Registry is optional at launch.
    • Amazon says Brand Registry is free, but the trademark work behind it is not.
    • If you are building a private-label brand, planning for Brand Registry early can save friction later.
    • If you are reselling existing brands, focus first on legitimate sourcing and clean invoices.

  12. Step 12: Complete the fulfillment branch

    Main guide step 12

    For Amazon FBA, do this in order:

    Why it matters: California operating note: FBA warehousing does not replace local city or county review for any home-office, storage, or local-delivery activity you perform yourself.

    • Register the account for FBA in Seller Central.
    • Create or convert listings to FBA.
    • Confirm product and FBA eligibility.
    • Prep, label, and pack inventory.
    • Create the shipment in Send to Amazon.
    • Send a small first batch and monitor receiving, returns, and defects.

  13. Step 13: Confirm product and category eligibility before scaling

    Main guide step 13

    Some Amazon categories are open, some require a Professional plan, some require approval, and some are not open to third-party sellers.

    • Some Amazon categories are open, some require a Professional plan, some require approval, and some are not open to third-party sellers.
    • A product can be eligible for sale in the Amazon store and still be ineligible for FBA.
    • Amazon's public beginner guidance still treats alcohol, tires, dangerous goods, and expiration-dated products as higher-friction examples.
    • Keep invoices, supplier information, and any compliance records ready.

  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
    • keep invoices and supplier records
    • keep tax reserves separate
    • avoid mixing personal and business spending
    • monitor margins, inventory age, and return patterns

Best practical order for the LLC launch path

  1. Choose the product lane first.
  2. Choose the entity name.
  3. Run the California name search.
  4. File LLC-1.
  5. Get the EIN.
  6. Open the bank account.
  7. Run the CDTFA analysis for your sales mix.
  8. File LLC-12 early instead of waiting near the deadline.
  9. Check county FBN rules if your operating name differs from the LLC name.
  10. Check city permits, zoning, and Los Angeles business-tax rules if applicable.
  11. Build the Amazon account and FBA workflow.
  12. Calendar FTB 3522, Form 568, FTB 3536 if needed, and the SOS biennial filing window.
Back to top Next: California tax stack
State filing and tax California tax stack Keep the California registration, tax, and maintenance rules together while you launch. Everyone 7 checks

1. EIN

Most LLCs should get one.

  • Most LLCs should get one.
  • Sole proprietors may use one even when not strictly required because it simplifies banking and business operations.

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

California uses CDTFA online registration for seller's permits and related accounts.

  • California uses CDTFA online registration for seller's permits and related accounts.
  • If you are doing business in California and directly selling taxable tangible personal property at retail, a seller's permit is the normal baseline.
  • Marketplace-only Amazon sales are a separate carveout and should not be confused with direct-sale fact patterns.

3. Marketplace or platform tax rule

If all California sales are marketplace sales facilitated by a registered marketplace facilitator, a marketplace seller is not required to register for a California seller's permit or Certificate of Registration-Use Tax solely for those sales.

  • If all California sales are marketplace sales facilitated by a registered marketplace facilitator, a marketplace seller is not required to register for a California seller's permit or Certificate of Registration-Use Tax solely for those sales.
  • If you also make direct sales, separate CDTFA analysis applies.

4. Resale purchases or exempt purchasing

CDTFA-230 may be used for resale purchases.

  • CDTFA-230 may be used for resale purchases.
  • California also allows another document if it contains the required resale-certificate elements.
  • An unregistered marketplace seller should explain why a permit is not required and should be prepared to identify the marketplace facilitator account or permit details tied to the resale path.

5. Entity tax treatment

California generally follows federal classification rules for LLCs.

  • California generally follows federal classification rules for LLCs.
  • Even so, California's LLC regime still matters because disregarded LLCs and partnership-classified LLCs must file Form 568, pay the annual $800 tax, and review the additional LLC fee rules when organized, registered, or doing business in California.

6. Entity filing-fee or franchise-tax rule

Return-due-date nuance:

  • FTB 3522 covers the annual LLC tax baseline of $800.
  • The annual LLC tax is generally due by the 15th day of the 4th month after the tax year begins.
  • Form 568 remains part of the baseline California LLC filing stack.
  • If California income is at least $250,000, California's additional LLC fee tiers are $900, $2,500, $6,000, and $11,790, and FTB 3536 is the estimated-fee form generally due by the 15th day of the 6th month.
  • A default single-member LLC owned by an individual generally uses the 15th day of the 4th month after year-end for the return due date.
  • LLC ownership and classification changes can shift that return deadline, so re-check the FTB due-date table if the ownership or tax classification changes.

7. If the founder changes entity type later

Treat a move from sole proprietor to LLC as a fresh agency-review event.

  • Treat a move from sole proprietor to LLC as a fresh agency-review event.
  • Re-check CDTFA registration, EDD payroll setup, local business-tax registration, bank records, and Amazon account documents instead of assuming they automatically transfer.

  • Get the EIN if applicable.
  • Open the bank account.
  • Complete the CDTFA analysis that applies to your mix of marketplace and direct sales.
  • Check local permits.
  • Complete Amazon verification.

  • Build accurate listings.
  • Complete prep and inbound shipping.

Monthly

  • Reconcile Amazon payouts, fees, refunds, and reimbursements.
  • Review tax reserves.
  • Review inventory age and stranded inventory issues.
  • Check account health, suppressed listings, and policy notices.

Quarterly

  • If CDTFA assigns you quarterly sales-tax filing, file on the cadence CDTFA gives you.
  • If you are making estimated income-tax payments, calendar them separately with your tax preparer.
  • Review whether your sales mix changed enough to alter the California marketplace-only registration answer.

Annual or periodic

Back to top Next: Common mistakes
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 before checking Amazon category and FBA eligibility
  • Treating Amazon marketplace collection as a complete answer to California tax registration
  • Using a brand or DBA before finishing the county filing branch
  • Ignoring city business-tax and zoning rules for a home-based setup
  • Mixing personal and business money
  • Launching with regulated products too early
  • Keeping weak supplier documentation
  • Missing LLC maintenance dates

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, a single-member LLC is usually the better long-term path in California because inventory, platform risk, and city compliance issues add up quickly.
