Sales tax is the obligation that most quietly turns into a real liability. Collected tax is not revenue — it is money you are holding for a state. When the amount collected does not tie to the amount remitted, that gap accrues silently until someone notices.
In Arizona, sales tax is administered by the Arizona Department of Revenue. The statewide base rate is 5.6%, local rates stack on top, and economic nexus for remote sellers sits at $100,000 in gross sales. Filing frequency is assigned by liability: monthly, quarterly, or annually by liability.

What trips people up in Arizona
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.
Registration and cadence in Arizona
Registration runs through the Arizona Department of Revenue. Once registered, Arizona assigns a filing frequency based on your liability — monthly, quarterly, or annually by liability. We work the monthly close backward from those due dates, so the liability account is reconciled to what you actually collected before anything is filed. When collected tax does not tie to the return, that gap is a real obligation, and it is far cheaper to find monthly than annually.
Problems this fixes
- Collected tax that does not tie to what was remitted
- Nexus triggered in a state nobody was tracking
- Local jurisdiction rates applied at the wrong rate or to the wrong address
