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. Because Arizona runs an annual bracket, low-volume e-commerce and online sellers can go twelve months between returns — which is exactly how long a liability account can drift before anyone looks at it.
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.

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%. That sits mid-table nationally, with local rates layered on top and sourced to the delivery address rather than to your own location. Sourcing is where this is won or lost, and with economic nexus set at $100,000 in gross sales, it becomes your problem the moment that threshold is crossed.
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.
