Frequently asked questions
- What is the Arizona income tax rate for self-employed people in 2026?
- Arizona uses a flat 2.5% individual income tax rate, so self-employment profit is taxed at 2.5% after Arizona's standard deduction, which matches the federal amount.
- Do Arizona freelancers pay state quarterly estimates?
- Yes, if you expect to owe $1,000 or more of Arizona tax. File Form 140ES on the same April, June, September, and January schedule as federal 1040-ES payments.
- How much should an Arizona 1099 worker set aside?
- Most Arizona gig workers land between 22% and 28% of net profit once federal income tax, 15.3% SE tax, and the flat 2.5% state tax are combined.
- Does Phoenix or Tucson add a local income tax?
- No Arizona city levies a personal income tax. Cities do charge transaction privilege (sales) tax on certain business activity, which is separate from income tax.
- Is Arizona mileage deducted at the federal rate?
- Yes. Arizona starts from federal adjusted gross income, so the $0.70 per business mile standard rate for 2026 flows straight through to your state return.
- Do I need an Arizona TPT license as a freelancer?
- Only if you sell taxable goods or certain taxable services. Pure service work such as writing, driving, or consulting generally does not require a transaction privilege tax license.
