Arizona taxes through the Arizona Department of Revenue at a 5.6% statewide base rate, with local rates stacking on top and economic nexus for remote sellers at $100,000 in gross sales. Filing runs monthly, quarterly, or annually by liability. For e-commerce & online sellers, that combination is what decides how much of your month-end is bookkeeping and how much is compliance.
Employer registration runs through the Arizona Department of Economic Security, and the entity is registered with the Arizona Corporation Commission. Arizona levies a Transaction Privilege Tax on the seller rather than a true sales tax on the buyer, and it is reported by business classification.

Sales tax nexus in Arizona
Economic nexus in Arizona is $100,000 in gross sales. For e-commerce & online sellers, that threshold is the one to watch, because it is reached by selling into the state — no office, no staff, no physical presence required. Once you cross it you are expected to register with the Arizona Department of Revenue and begin collecting. We track your Arizona sales against it and tell you before you cross, not after.
Marketplace sales vs. your own channels in Arizona
Marketplace facilitator rules mean large platforms generally collect and remit Arizona tax on sales made through them. Your own site, wholesale, and direct sales are a different matter — those remain yours to collect and report. Keeping the two streams separate in the books is what makes the Arizona Department of Revenue return match reality.
Arizona rates and sourcing
The Arizona statewide base rate is 5.6%. Local rates stack on top and are generally sourced to the delivery address, so the effective rate varies within the state. Getting sourcing right is what keeps the liability account matching what you actually collected.
Filing cadence in Arizona
Arizona assigns filing frequency by liability — monthly, quarterly, or annually by liability. Because Arizona includes an annual bracket, a low-volume seller here can go a full year between filings, which is exactly when a liability account drifts unnoticed. We reconcile it monthly regardless of when the return is due.
We keep the books. You run the business.
Categorization, reconciliation, month-end close, and clean financial statements — with nothing left for you to chase.
