TPT Is Not Quite a Sales Tax
Most states have a sales tax charged to customers. Arizona has transaction privilege tax, or TPT, which is a tax on the seller's privilege of doing business in the state. Customers usually see it on the receipt, but legally it is the business's tax.
Cities add their own privilege tax on top of the state rate. The Arizona Department of Revenue collects both for most cities, including Mesa, Gilbert, Chandler and Tempe, through one TPT license and one return.
That matters at a sale because unpaid TPT doesn't simply stay with the seller.
What Successor Liability Means
Arizona law requires the buyer of a business, or of its stock of goods, to hold back enough of the purchase money to cover the seller's unpaid TPT, plus interest and penalties.
The holdback stays in place until the seller produces a receipt or certificate from the Department showing the tax is paid.
A buyer who doesn't hold back enough can become personally liable for what the seller owed. Buyers' attorneys know this, and they will not skip it.
Buying only assets doesn't avoid it
Some owners assume that an asset sale, where the buyer takes equipment, customer lists and goodwill but not the company itself, means none of this applies. Department rulings have rejected that argument. Buyers of assets have been held liable as successors.
Cities apply the same idea
Department rulings on city privilege tax follow the same logic. In one case a buyer was held liable for a city's tax because it didn't get the city's certificate of good standing. Your buyer will care about city tax as much as state tax.
What the Holdback Means for You
In practice, the purchase agreement says part of your price stays in escrow until you deliver the Department's paperwork. The money is still yours. It just sits with someone else until the state confirms your account is clean.
The certificate protects the buyer too. A buyer holding it is generally not responsible for extra tax a later audit finds for your periods before the sale. That protection is the reason buyers insist on it.
How to Get Ready
- Pull your TPT account history on AZTaxes.gov a few months before you expect to close.
- File any missing returns and pay balances, including old interest or penalties.
- Check every business location and city code on your license, since each one reports separately.
- Ask the Department for its receipt or certificate as the closing date firms up.
- Give the buyer the document so the holdback is released.
Don't wait until the week of closing. If the review turns up a missed period, you want time to fix it.
Common Reasons Clearance Takes Longer
- A month or quarter that was never filed, often from a slow season
- A second location or city code still open under the license
- Penalties from an old notice that was never resolved
- Returns filed under the wrong business code
- Use tax on equipment bought from out of state that was never reported
Contractors and Service Companies
TPT applies differently depending on what you do. Retailers, restaurants and contractors each have their own rules, and some service work isn't taxed at all.
Roofers, pool companies and solar installers in particular should have their CPA confirm how past work was reported before a buyer's accountant asks.
Our sector pages, like selling a roofing company, touch on what buyers check in each trade.
Asset Sale or Stock Sale
In an asset sale, the usual structure for companies under a few million dollars, you close your TPT license and the buyer applies for its own. Arizona TPT licenses don't transfer to a new owner.
In a stock sale, the company keeps its license under new owners. Then the buyer's concern shifts to everything the company already owes, handled through diligence and the purchase agreement.
What Comes After Closing
Clearance shows you are paid up. You still have to stop the accounts. That means a final TPT return, canceling the license and closing your withholding account. Read cancel your Arizona TPT license and withholding after a sale for those steps.
Your payroll and county filings follow, covered in Arizona unemployment account transfer when a buyer takes over and Maricopa County personal property return in the year you sell.
