Quick Answer
Arizona sales tax nexus can be created by physical presence, economic activity, marketplace sales, inventory, employees, contractors, events, affiliates, or other state-specific facts. A rate lookup alone does not prove collection duty.
Arizona Nexus Rules Checklist
- List all physical activity connected to Arizona.
- Measure sales volume and transaction counts into Arizona for the lookback period used by the state.
- Separate marketplace sales from direct website, wholesale, phone, invoice, and in-person sales.
- Check whether marketplace facilitator rules, economic nexus thresholds, or registration requirements apply.
- Use the official state source before registering, collecting, or changing checkout settings.

How This Connects to Local Rates
The statewide rate of 5.6% is only one part of the research process. Local county, city, district, parish, borough, and special-purpose rules may change the final combined rate, and product taxability can change whether tax applies at all.

Does this page replace professional tax advice?
No. It is for general information only. For legal, accounting, audit, or filing decisions, use the official state source or a qualified tax professional.
Where should I verify the current Arizona rule?
Use the official state tax source and filing portal linked on this page, then save the source check date with your records.
Can local sales tax still matter?
Yes. Registration, nexus, filing, exemptions, and local rates are separate checks. A statewide rate does not always answer the final transaction question.
