Phoenix, AZ Bookkeeping Services — The Tax Is Yours, Not Your Customer’s
Last Updated: October 6, 2026Phoenix businesses carry the Transaction Privilege Tax themselves. Arizona’s TPT is levied on the seller rather than the buyer, with the state at 5.6% and Phoenix and Maricopa County adding their own on top — and the rate depends on your business classification, not just your location. Get the classification or the collection wrong and the shortfall comes out of your margin, not your customer’s pocket. Arizona asks LLCs for no annual report at all, which removes the one calendar prompt that makes owners elsewhere review their books. In the Valley, the monthly close is the only thing standing between a small coding error and a years-long accumulation.
Get Started — Money-Back Guarantee
Phoenix owners and their CPAs come to us because TPT exposure builds quietly when nothing in the calendar forces a review — and because catching it is a reconciliation, not an opinion. Dedicated bookkeepers, monthly reconciliations, and tax-ready financials — plans from $75/month, extra hours at $15/hour, and wholesale $10/hour rates for CPA firms — backed by a 100% money-back guarantee on your 1st retainer, refundable on the unused balance.

Running the Numbers in Phoenix
The Phoenix metro has been among the fastest-growing in the country for a decade, and the growth is broad: semiconductor and advanced manufacturing investment, a large and expanding construction sector, healthcare, logistics, and a very large base of small service businesses serving new residents.
Two of those create specific TPT difficulty. Construction and contracting has its own treatment under Arizona TPT that depends on the nature of the work, and it is the classification we most often see handled inconsistently. Commercial leasing is taxable under TPT in a way that surprises owners who have operated in other states. Both reward books that separate revenue by activity from the start.

An Under-Collected Sale Is Paid Out of Margin
Because TPT is the seller’s liability, a taxable sale that went out without the tax applied does not become the customer’s problem. It becomes a cost. On a job with a 12% margin, an 8.6% combined TPT rate that was never charged takes most of the profit with it.
What makes this dangerous in practice is that nothing alerts you. The sale looked fine, the customer paid, the bank balance went up. The gap only appears when taxable sales are reconciled against TPT remitted — which is a monthly bookkeeping routine, not something a tax return will surface on its own.
We run that reconciliation as part of every close, split by classification and jurisdiction, so a mis-set rate is caught in weeks rather than discovered in an audit.
Contracting Is the Classification That Causes Trouble
Arizona’s treatment of construction under TPT is genuinely complex and turns on the nature of the work performed. It is the single most common source of Arizona TPT error we encounter, and it is not a problem a bookkeeper should pretend to solve — it is a determination for your CPA or a tax specialist.
What we can do, and what makes their job possible, is keep contracting revenue recorded by job and by activity type, with materials and labour separated, so the facts needed to apply the right treatment exist in the ledger. Job costing is standard on our Enterprise plan at $300/month for 20 hours, with retainage tracked properly on both sides.
No Annual Report Means No Annual Prompt
Arizona LLCs file no annual report. That is a real saving and part of why the state is popular for entity formation. It also means a year can pass with nothing requiring you to look at your records — no filing, no fee, no reminder — while TPT obligations accrue every single month.
Almost every Phoenix business that has come to us badly behind was behind on TPT rather than income tax, for exactly this reason. A monthly close is the substitute for the prompt the state does not send. At $75/month with five hours included, it costs less than most of the exposures it prevents.

Phoenix Bookkeeping FAQs
What happens if I did not charge TPT on a taxable Phoenix sale?
You still owe it. TPT is levied on the seller, so an uncollected amount comes out of your margin rather than being recoverable from the customer as a matter of course. This is why reconciling taxable sales against TPT remitted every month matters more in Arizona than the equivalent routine does in a buyer-tax state.
What TPT rate applies in Phoenix?
The state’s 5.6% plus Maricopa County and City of Phoenix rates, and the applicable rate also depends on your business classification. Confirm your classification and the current combined rate with the Arizona Department of Revenue or the City of Phoenix — we keep revenue separated by activity and jurisdiction so the correct rate can be applied and defended.
Do you handle TPT for construction businesses?
We handle the bookkeeping that TPT determinations depend on: revenue recorded by job and activity type, materials and labour separated, retainage tracked. Arizona’s contracting treatment is complex and turns on the nature of the work, and that determination belongs with your CPA or a tax specialist. We will not pretend otherwise.
Arizona has no annual report, so why do I need monthly bookkeeping?
Because TPT accrues monthly whether or not anything in the calendar reminds you. In states with an annual filing, that filing prompts a yearly look at the records. Arizona sends no such prompt, which is precisely why the businesses that fall furthest behind here tend to be behind on TPT rather than income tax.
Do you have a Phoenix office?
No. We are a fully virtual bookkeeping company — founded in Vienna, Virginia on May 25, 2005 and headquartered in San Juan, Puerto Rico today, US-registered with delivery centers in India, which we disclose on our About page. We are not going to imply a Phoenix storefront we do not have. What we do have is Phoenix clients served remotely since 2005, a dedicated bookkeeper on plans from $75/month, and a 100% money-back guarantee on your 1st retainer, refundable on the unused balance.
