Medical & Dental Practices Bookkeeping in Arizona

Employer registration in Arizona runs through the Arizona Department of Economic Security, a different agency from the Arizona Department of Revenue that handles your sales tax — a separate account number, a separate login, and separate deadlines. Businesses routinely register for one and forget the other, then discover the gap when a notice arrives.

Registering to do business in Arizona runs through the Arizona Corporation Commission, with tax accounts through the Arizona Department of Revenue and employer accounts through the Arizona Department of Economic Security. Arizona treats these as wholly independent, so being in good standing with one says nothing about the others — and the sales tax account is the one that accrues a real balance while you are not looking.

Beyond sales tax, Arizona entities have their own obligations — registration with the Arizona Corporation Commission, and whatever annual entity-level tax or report the state imposes. 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. These are recorded as they accrue rather than discovered at year end.

Whether medical & dental practices services are taxable in Arizona is the question that catches people out — states differ enormously, and several have been broadening what counts. 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. We code service revenue separately from any product revenue so the treatment is explicit rather than assumed.
