What is the Arizona sales tax registration threshold?
The Arizona sales tax registration threshold is $100,000, measured over the previous or current calendar year. Cross it and you must register for Arizona sales tax with the Arizona Department of Revenue. You then charge sales tax on sales to customers in Arizona.
Do marketplace sales count toward this threshold?
No. Arizona (sales tax) excludes sales made through a registered marketplace facilitator from the underlying seller's own economic nexus threshold. Your Amazon, Etsy and eBay volume does not push you toward the figure on this page - only your own direct sales do.
Statute: A.R.S. 42-5044(A)(1)
Most exclusions of this kind are conditional on the facilitator being registered and actually collecting the tax, and some states ask the seller to hold the facilitator's certification. Confirm which applies to your marketplaces before relying on it.
What's different about Arizona
Arizona calls its sales tax Transaction Privilege Tax (TPT). It's legally a tax on the seller, not the buyer, though it's passed through in practice.
State registration isn't the whole story
Arizona is a home-rule jurisdiction: local cities and counties administer their own sales tax separately from the state. Registering with the state does not register you locally - check local requirements once you cross.
When do you need to register?
Economic nexus: once your sales into the state pass its threshold (commonly $100k or 200 transactions), you must register and collect that state's sales tax.
Deadline: Register before your next sale - many states apply nexus prospectively from the crossing.
