The Arizona payment schedule on $50,000
A single filer with $50,000 of net 1099 profit, taking the standard deduction and paying 90% of this year's liability:
| Due | Income earned | To the IRS | To Arizona |
|---|---|---|---|
| April 15, 2026 | Jan 1 - Mar 31 | $2,190 | $261 |
| June 16, 2026 | Apr 1 - May 31 | $2,190 | $261 |
| September 15, 2026 | Jun 1 - Aug 31 | $2,190 | $261 |
| January 15, 2027 | Sep 1 - Dec 31 | $2,190 | $261 |
| Year | $8,759 | $1,046 | |
The Arizona side of each payment
Arizona taxes the same 1099 profit at a flat 2.5%, so a second payment goes to the state each quarter, about $261 on the $50,000 example, against $1,162 of Arizona income tax for the year.
The 2026 dataset carries the federal 1040-ES dates but not state-specific due dates, so confirm Arizona's schedule and voucher with its tax agency, several states do not match the federal calendar exactly.
What each quarter costs at three income levels in Arizona
A single filer taking the standard deduction, at three levels of net profit. The federal column moves with the self-employment tax and the federal brackets; the Arizona column moves with Arizona's own rules, so the two do not scale together. Use the calculator above for the other filing statuses:
| Net 1099 profit | Per quarter to the IRS | Per quarter to Arizona | Effective rate |
|---|---|---|---|
| $25,000 | $923 | $131 | 18.7% |
| $50,000 | $2,190 | $261 | 21.8% |
| $100,000 | $5,032 | $523 | 24.7% |
Staying inside the safe harbor
Payments are required once you expect to owe $1,000 or more, which the $50,000 example above does, at $10,894 for the year. Two targets avoid a penalty and you need only the lower; the hub explains both routes and the penalty.
What the rate alone doesn't tell you about Arizona
Arizona is a community property state. In community property states, income earned during marriage is generally owned equally by both spouses. This affects QJV eligibility, MFS filing strategies, and retirement account contribution rules.
What a quarter costs in the states Arizona borders
On $50,000, Arizona charges $1,250 of state income tax. Of the 4 states it borders, Nevada is the lightest at nothing at all and Utah the most expensive at $2,250, a spread of $2,250 on the same income.
| State | State tax per quarter | vs Arizona |
|---|---|---|
| Nevada | No income tax | −$281 a quarter |
| California | $302 | +$21 a quarter |
| New Mexico | $486 | +$205 a quarter |
| Utah | $506 | +$225 a quarter |
- Nevada has no income tax at all, so the same work done there costs $1,250 less in state tax than it does in Arizona.
- California would take $93 more, $1,343 against Arizona's $1,250.
- New Mexico would take $910 more, $2,160 against Arizona's $1,250.
- Utah would take $1,000 more, $2,250 against Arizona's $1,250.
What this schedule assumes
- Single filer, standard deduction, net 1099 profit after expenses, no W-2 withholding.
- Four equal payments rather than annualised income.
- Arizona due dates are not in the 2026 dataset, the dates shown are the federal ones.
Arizona quarterly tax questions
How much should I send each quarter in Arizona?
On $50,000 of net 1099 profit as a single filer, about $2,190 to the IRS plus roughly $261 to Arizona. That is 90% of this year's liability, split four ways.
Does Arizona use the same due dates as the IRS?
Arizona requires its own estimated payments, but the 2026 dataset carries only the federal 1040-ES dates (April 15, 2026, June 16, 2026, September 15, 2026, January 15, 2027). Confirm Arizona's own schedule with its tax agency before assuming they line up.
