Your planning rate

Arizona taxes income at one rate, so planning is easy: your state tax is roughly 2.5% of your profit. The planning rates above are a touch lower because half of your self-employment tax comes off first.

In our quarterly tax calculator, enter 2.5% (or 2.5% if your profit is nearer $100,000) as your state rate.

Arizona estimated tax payments

Arizona expects freelancers who will owe state tax to pay during the year too. Most states use the same four dates as the IRS, but a few don't, so confirm the dates and payment options with the Arizona Department of Revenue.

An easy habit: when you make each federal quarterly payment, make the state one the same day.
