Phoenix local rules

Local income tax: No city income tax in Phoenix.
Phoenix Transaction Privilege Tax (TPT): Phoenix levies a transaction privilege (sales) tax on certain business activities on top of the state tax; the city rate varies by activity and is 2.8% on most activities after a 0.5-point increase took effect July 1, 2025. A business engaged in a taxable activity (for example, retail sales) needs a TPT license.
City business license: The City of Phoenix does not have or issue a general business license; only certain regulated activities require a city license or approval.
Also worth knowing: No city income tax: Arizona is not among the states with city- or county-level income taxes per the Tax Foundation's 2026 list (secondary source; no official Arizona page stating this was found). Whether a gig worker or freelancer needs a Phoenix TPT license depends on whether their specific business activity is taxable under the city tax code; the city page does not list every activity.

State estimated tax: You must make 2026 Arizona estimated payments if your Arizona gross income was over $75,000 in 2025 and is over $75,000 in 2026 ($150,000 for both years if married filing jointly). Same dates as federal: April 15, June 15, and September 15, 2026, and January 15, 2027. Form 140ES.
Arizona transaction privilege tax (TPT): TPT is a tax on the vendor for the privilege of doing business in Arizona. A sole proprietor in a taxable classification, such as retail sales, restaurants and bars, contracting, or rentals, needs a state TPT license ($12 per location) and often a city license too. The state rate is 5.6%, plus county and city rates (ADOR TPT rate table, October 2026).
Minimum wage (2026): $15.15 an hour; tipped cash wage $12.15 an hour. The maximum tip credit is $3.00. The Industrial Commission of Arizona set the 2026 state rate at $15.15 (up from $14.70) effective January 1, 2026 (azica.gov).

Tucson also has its own higher local minimum wage.
Declaration of Independent Business Status (A.R.S. 23-1601): An optional signed declaration in which the contractor affirms they run their own business and are responsible for their own taxes and licenses. It must also show at least six of ten listed independence factors. When the parties act consistently with it, the declaration creates a rebuttable presumption that the worker is an independent contractor.
Qualified marketplace contractors (A.R.S. 23-1603): Workers who find jobs through a qualified marketplace platform are independent contractors for all state and local law purposes, including unemployment and workers' compensation, if three conditions are met: they are paid for output, they have a written contract, and they keep control over their hours and their freedom to work elsewhere.
