If you want to open Facebook Marketplace in Arizona, you usually need to do five things in order:
- Choose your setup: sole proprietorship vs single-member LLC.
- Decide whether your first sales are local pickup or direct payment sales or onsite checkout with shipping, because those branches do not have the same Arizona tax answer.
- If you will take payment yourself on Arizona sales, register for Arizona TPT before the first taxable sale and do not assume the marketplace-only no-license branch applies.
- Verify Phoenix licensing, city-tax, zoning, and home-business rules if you will operate from home there.
- Build a small Facebook Marketplace launch using your main Facebook profile, low-risk physical products, and a very simple first fulfillment model.
Practical first-launch recommendation
If you are testing casually with minimal risk, sole proprietor can work.
If you intend to build a real repeat-sales business, single-member LLC is usually the better long-term path.
For Facebook Marketplace specifically, the legal entity choice and the account-access choice are separate. The public Meta pages point to an individual seller model that uses the founder's main profile, even if the seller keeps an LLC, EIN, and business bank account behind the scenes.
Avoid these first-launch mistakes
- Assuming "Marketplace" automatically means no Arizona TPT
- Using an additional Facebook profile instead of the required main profile
- Treating local cash or person-to-person deals as if they had Meta protection
Arizona-specific friction
The Arizona tax answer turns on who takes payment and what transaction flow is actually happening, not just on the fact that you used Facebook Marketplace to find the buyer.

- Local pickup, door dropoff, public meetup, and seller-managed shipping with your own payment are the strongest reasons to treat the sale as a direct Arizona retail sale.
- Arizona's no-license marketplace-only branch and Arizona's resale certificate branch are not the same answer.
- Phoenix can care separately about city tax licensing and home-occupation rules.

- That does not mean insurance is a bad idea. If you are selling physical products repeatedly, especially used electronics, children's goods, or anything with injury risk, look at CGL and product liability coverage before scale.
- Do not confuse Meta seller protection for onsite-checkout claims with business insurance.
