Arizona’s individual income tax was reduced to a flat 2.5% rate in 2023, one of the lowest flat rates in the country. The corporate income tax rate is 4.9%. Arizona does not impose a traditional sales tax; instead, it uses a Transaction Privilege Tax (TPT), which is a tax on the privilege of doing business in the state. The TPT rate varies by business activity type and location. In Phoenix, the combined state, county, and city TPT rate is approximately 8.6% for retail sales. Businesses must register with the Arizona Department of Revenue for TPT before beginning taxable activity.
Arizona’s Transaction Privilege Tax is structured differently from a traditional sales tax and catches many new Phoenix business owners off guard. Unlike a traditional sales tax collected from customers, the TPT is technically a tax on the business, though it is commonly passed on to customers. Different business activities have different TPT rates and reporting requirements. Phoenix’s rapid growth has also created nexus issues for businesses expanding into or out of the state. The real estate and construction sectors, which are major components of Phoenix’s economy, have specific TPT treatment that requires specialist knowledge.
TurboTax Business and QuickBooks handle federal returns and basic Arizona income tax well for simple businesses. However, Arizona’s TPT system is complex enough that even moderately active businesses typically benefit from CPA guidance on registration, rate determination, and filing.
Many Phoenix entrepreneurs manage basic returns with TurboTax Business but find that Arizona’s TPT complexity and multi-rate structure quickly justify the investment in a local CPA, particularly for businesses selling goods or performing contracting work.
Phoenix CPAs serve businesses across the greater Phoenix metro including Maricopa County, Scottsdale, Tempe, Mesa, Chandler, Gilbert, and Glendale.

Arizona’s Transaction Privilege Tax (TPT) is a tax on businesses for the privilege of conducting business in the state. Unlike a traditional sales tax, which is legally a tax on the buyer, the TPT is legally a tax on the seller. In practice, most businesses pass the cost to customers. The TPT has different rates for different types of business activities, including retail, restaurant, construction contracting, and professional services. Businesses must register with the AZ Department of Revenue and often with city and county authorities as well.
Phoenix business owners follow the standard federal quarterly estimated tax schedule. For Arizona income tax, estimated payments are also required for individuals and businesses expecting to owe more than $1,000 in state tax. Arizona due dates generally align with federal deadlines. The state also requires TPT returns on a monthly, quarterly, or annual basis depending on your tax liability level. A Phoenix CPA can set up a payment and filing schedule that covers all your obligations.
Arizona taxes S corporation income at the individual level at the flat 2.5% rate, which is very competitive. An S corporation can save on federal self-employment taxes by splitting income between salary and distributions. The Arizona flat rate makes the state-level comparison simpler than in states with graduated rates. A Phoenix CPA can model both structures with your specific income to identify the more tax-efficient approach.
Construction and real estate businesses face particularly complex TPT treatment in Arizona, with specific rules for prime contractors, subcontractors, and owner-builders. Restaurants and food service businesses deal with different TPT rates for prepared food versus grocery items. Technology companies may face nexus questions as their customer base expands. Healthcare providers have specific exemption and taxability questions. A Phoenix CPA with sector-specific experience can navigate these complexities more effectively than general tax software.
Phoenix business owners can take all standard federal deductions including Section 179 equipment expensing, business vehicle mileage, home office deductions, and ordinary business expenses. Arizona conforms to most federal deductions for state income tax purposes. For TPT, businesses can deduct certain qualifying resales and exempt transactions from their gross receipts. A Phoenix CPA can identify deductions specific to your industry and ensure you are capturing all available savings at both federal and state levels.
