Gig Workers in Phoenix, AZ: taxes and retirement for 2026
For rideshare and delivery drivers, shoppers and app-based workers in Phoenix, AZ. Arizona has a flat 2.5% state income tax for 2026. Here are the 2026 rules, a worked example and the official sources.
What's different in Phoenix
- 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.
Arizona rules for gig workers
- State income tax (2026)
- Arizona has a flat 2.5% state income tax for 2026. The 2026 Form 140ES worksheet figures estimated tax at 2.5% of Arizona taxable income. Arizona also lets taxpayers elect to report small business income separately on Form 140-SBI.
- 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).
- 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. Sealed freight and parcel delivery is excluded.
Federal rules for 2026
Mileage is the big deduction
Business miles are deductible at the IRS standard rate: $0.725 a mile for miles driven January through June 2026 and $0.76 from July 1. Keep a log of each trip; Gigaverse lets you start and stop trips in the app.
App fees and phone
Platform service fees, a business share of your phone and plan, insulated bags and parking or tolls while working are deductible.
Self-employment tax
On top of income tax, self-employed people pay 15.3% on 92.35% of net profit: 12.4% Social Security up to the 2026 wage base of $184,500, plus 2.9% Medicare with no cap. Half of it is deductible.
Quarterly estimated taxes
No one withholds tax from self-employment income, so you generally pay estimates four times a year if you expect to owe $1,000 or more. For 2026 income the federal dates are April 15, June 15 and September 15, 2026, and January 15, 2027. Paying 100% of last year's tax (110% if your AGI was over $150,000) in four equal installments avoids the underpayment penalty.
A worked example
| Mileage deduction | $11,138 |
|---|---|
| Net profit after mileage | $33,863 |
| Self-employment tax | $4,785 |
| Self-employment tax the mileage saves | $1,574 |
Miles split evenly between the two 2026 rates. Federal figures only; the mileage also lowers income tax. Computed from 2026 IRS limits (Notice 2025-67, Rev. Proc. 2025-32) and the SSA wage base.
