Self-Employed Tax Calculator — Arizona (2026)
Self-employed in Arizona? Your tax bill has three layers that a W-2 employee never sees in full: 15.3% self-employment tax on 92.35% of net profit, federal income tax, and Arizona state income tax. This calculator applies all three to your 2026 net profit and shows the quarterly amount you should be setting aside. Arizona uses a flat personal income tax of 2.50% applied to taxable income after a state standard deduction of $16,100.

Self-employment tax vs Arizona income tax
Self-employment tax is federal and identical in all 50 states: 12.4% Social Security up to $184,500 of net earnings plus 2.9% Medicare with no cap. Half of it is deductible against income tax, which is why the calculator subtracts it before applying brackets.
Arizona then taxes essentially the same profit figure at 2.50%. On $80,000 of net profit that adds roughly $1,456 to the bill.
Arizona has no separate city or county income tax, so the state figure above is the full sub-federal income tax you pay.
Deductions that matter for Arizona freelancers
Net profit — not gross revenue — drives every number here. Ordinary and necessary business expenses reduce SE tax, federal tax, and Arizona tax simultaneously: the 2026 standard mileage rate of $0.67/mile, home-office square footage, software, equipment, professional insurance, and the self-employed health insurance deduction.
Retirement plans go further. A SEP-IRA or solo 401(k) reduces income tax (though not SE tax) and is often the largest single deduction available to a profitable tech contractor in Phoenix.
Working for yourself in Arizona
Arizona's economy leans on tech, aerospace, and healthcare, which shapes the contractor market around Phoenix — and your fixed costs. With one-bedroom rent near $1,450, a freelancer needs meaningfully more gross revenue than an employee to reach the same lifestyle, because there is no employer paying half of FICA.
Arizona has one of the lowest flat state income tax rates in the country at just 2.5%, fully phased in in 2023.
Local and payroll taxes Arizona adds on top
Arizona adds no state-mandated employee payroll deduction beyond FICA, so nothing extra is taken from your gross pay at the state level.
Arizona has no separate city or county income tax, so the state figure above is the full sub-federal income tax you pay.
Nobody withholds these for you when you are self-employed in Arizona. Local wage taxes, city business licences and gross-receipts style levies are yours to register for and remit alongside your quarterly federal and state estimates.
Working across a state line from Arizona
Arizona holds income-tax reciprocity agreements with California, Indiana, Oregon and Virginia. If you commute between them, your wages are taxed only by your state of residence — file the exemption certificate with your employer so the wrong state is not withheld from every paycheck.
Remote and hybrid work complicates this further: most states tax income where the work is physically performed, so a Phoenix resident spending part of the year at a client site in Nevada may owe a nonresident return there. Keep a day-count log if you split time between states.
The rest of your Arizona tax bill
Arizona charges a 5.6% state sales tax, homeowners pay an average effective property tax of 0.62% of market value, and the minimum wage in force during 2026 is $15.15 an hour.
Combined transaction privilege tax averages about 8.4%.
Income tax is only one part of a state's take. Arizona recovers revenue through sales and property tax as well, which is why headline income tax rates alone are a poor guide to how far a salary really goes. Arizona exempts Social Security and up to $2,500 of federal, state and Arizona local pension income; other retirement income is taxed at the flat rate.
Arizona vs Nevada on the same salary
On a $90,000 salary, a single filer keeps about $70,298 a year in Arizona against roughly $72,145 in Nevada — a difference of $1,848, or $154 a month.
Effective combined rates are 21.9% in Arizona and 19.8% in Nevada. Set that gap against living costs: index 103 here versus 102 there, with property tax at 0.62% and 0.55% respectively.
