Arizona Biweekly Paycheck Calculator 2026

Here is exactly what your biweekly paycheck looks like in Arizona at common annual salary levels in 2026. Calculated for a single filer, standard W-4, biweekly pay frequency, no pre-tax deductions.

Single filer · standard W-4 · biweekly pay (26 periods/yr) · no pre-tax deductions · 2026 IRS withholding tables · Arizona published 2026 withholding method. Actual paychecks vary based on filing status, allowances, and deductions.

Arizona withholds state income tax from every paycheck. Your biweekly paycheck includes these deductions:

• Federal income tax (2026 IRS withholding tables)
• Arizona state income tax (withheld each pay period)
• Social Security tax — 6.2% on wages up to $184,500
• Medicare tax — 1.45% on all wages
• Employee benefit deductions

A biweekly pay schedule means you receive a paycheck every two weeks — 26 paychecks per year. To find your gross biweekly pay, divide your annual salary by 26:

Two months per year you will receive three biweekly paychecks instead of two. This is sometimes called a "three-paycheck month." Because benefit deductions are often fixed per paycheck, the extra check can feel larger than usual.

Your net biweekly paycheck in Arizona depends on your annual salary, W-4 filing status, Arizona state withholding elections, retirement contributions, health insurance deductions, and any additional withholding.

Arizona is the only state that lets the employee choose a flat withholding percentage from a menu on Form A-4 rather than deriving it from allowances or a table. Whatever rate you elect is applied to every biweekly paycheck for the rest of the year. The calculator above uses the elected rate you enter, which is why an Arizona estimate is only as good as the A-4 on file with your employer.

This is unusually consequential on a 26-period schedule, because a wrong election does not self-correct. A rate set too low quietly accumulates a balance due across all 26 checks; a rate set too high hands Arizona an interest-free loan for the year. Nothing in the payroll system flags either case — Arizona simply applies the percentage you asked for.

Arizona withholding is not trued up retroactively when you file a new A-4. The new percentage applies from the next payroll run forward, so if you change it in July you have roughly 13 biweekly checks to absorb the correction rather than 26.

That means a mid-year fix has to overshoot to land in the right place. If you have been under-withholding at the old rate, picking the technically correct percentage for your income will not close the gap — the shortfall from the first half of the year is still there. The A-4 also has a line for an extra flat dollar amount per paycheck, which is usually the cleaner way to catch up.

Arizona maintains reciprocal agreements with California, Indiana, Oregon and Virginia. A resident of one of those states working in Arizona can file Arizona Form WEC to stop Arizona withholding and pay only their home state; an Arizona resident working in one of those states can do the equivalent there.

Without the exemption form, both states withhold and you wait until filing to recover the excess — for a biweekly worker that is 26 undersized deposits before any of it comes back. Arizona has no agreement with Nevada, New Mexico, Utah or Colorado, so a cross-border commute in those directions is handled through credits at filing instead.
