If you want to open Amazon FBA in Arizona, you usually need to do five things in order:
- Choose your setup: sole proprietorship vs single-member LLC.
- Get your federal and Arizona registrations in place before launching, especially your EIN and Arizona TPT branch if you will make direct taxable sales.
- Verify local county or city permit, zoning, and home-business rules, especially if you will work from home in Phoenix.
- Open and verify your Amazon seller account, choose the right selling plan, and activate the FBA branch.
- Launch only after your product, tax, sourcing, listing, and fulfillment setup are 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 before checking legal and Amazon restrictions
- Assuming Amazon marketplace tax collection means no Arizona tax work ever applies
- Using a brand name without checking trade-name, trademark, or supplier-rights issues
Arizona-specific friction
LLC publication still matters in Arizona and can slow careless founders down.

- TPT licensing is not a simple yes/no if you use Amazon: marketplace-only sales and direct sales are treated differently.
- Local permit and home-occupation rules can still matter even when the state filing branch looks light.
Amazon-specific friction

- Some categories need approval or a Professional plan before you can scale.
- FBA prep mistakes can create extra cost fast.
- The clean public insurance answer is limited because the strongest wording lives in login-gated Seller Central materials.
Insurance reality
For physical products, commercial general liability and product liability coverage become increasingly practical as you scale.

- Public Amazon forum material says commercial liability insurance may be required within 30 days after exceeding USD 10,000 in gross proceeds in one month, or earlier if Amazon asks for it.
- The underlying agreement language is login-gated, so treat the public forum evidence as a caution flag and re-check the live Seller Central insurance wording before acting.
