Arizona Paycheck
Calculator

Estimate Arizona take-home pay using federal payroll taxes plus the employee's Arizona Form A-4 withholding election.

The Arizona paycheck calculator estimates take-home pay after federal taxes, Arizona income tax withholding, Social Security, Medicare and other applicable deductions. Arizona uses a distinctive withholding election system: employees choose a percentage of gross taxable wages on Form A-4 rather than relying only on the state's 2.5 percent individual income tax rate.

For 2026, Form A-4 percentage choices are 0.5 percent, 1.0 percent, 1.5 percent, 2.0 percent, 2.5 percent, 3.0 percent or 3.5 percent. Employees can also request additional withholding. A paycheck calculator therefore needs the employee's actual A-4 election to estimate Arizona withholding accurately.

An accurate Arizona paycheck estimate requires payroll details that describe the employee's real compensation and withholding choices.

How Is Arizona Take-Home Pay Calculated?

Arizona take-home pay starts with gross earnings then subtracts federal taxes, Arizona withholding and other employee deductions. The state withholding amount is based on the employee's elected A-4 percentage plus any additional amount requested.

Estimated Net Pay = Gross Pay - Federal Withholding - Arizona Withholding - Social Security - Medicare - Other Employee Deductions

The calculator should calculate taxable wages before applying the Arizona percentage. Pretax deductions can reduce gross taxable wages, so the amount subject to the employee's A-4 election can be lower than total gross pay.

Arizona Withholding Is Not the Same as the 2.5 Percent Tax Rate

Arizona's individual income tax rate is 2.5 percent for tax year 2023 and later, but payroll withholding is based on the employee's Form A-4 election. The available withholding percentages range from 0.5 percent through 3.5 percent.

This distinction matters when estimating a paycheck. An employee who elects 2.0 percent withholding should not automatically have 2.5 percent deducted simply because 2.5 percent is the state individual income tax rate.

For more detail on the state tax itself, review the Arizona income tax guide.

What Happens If an Employee Does Not Submit Form A-4?

Arizona instructs new employees to complete Form A-4 within the first five days of employment. If the form is not provided, the employer is generally required to withhold 2.0 percent of gross taxable wages until a valid A-4 is received.

A calculator can therefore use 2.0 percent only when that default rule actually applies. If the employee has made a different valid election, the calculator should use the employee's selected percentage instead.

Federal Taxes on an Arizona Paycheck

Federal income tax withholding is separate from Arizona withholding. It depends on the employee's 2026 Form W-4 information plus the IRS withholding methods.

Social Security generally applies at 6.2 percent on covered wages up to the $184,500 wage base for 2026. Medicare generally applies at 1.45 percent on covered wages without a general wage ceiling. Higher wage employees can also become subject to Additional Medicare Tax withholding after the federal employer threshold is crossed.

Arizona Hourly Paycheck Calculator

For hourly payroll, multiply the regular hourly rate by regular hours then add qualifying overtime and other taxable earnings before calculating deductions.

Hourly Gross Pay = Regular Earnings + Overtime + Other Taxable Earnings

Arizona's statewide minimum wage is $15.15 per hour effective January 1, 2026 for covered employees. Local minimum wage requirements can be higher in some jurisdictions, so the applicable wage rate should be established before the paycheck calculation begins.

Arizona Salary Paycheck Calculator

For a salaried employee, annual salary is converted into per-pay-period gross pay before federal and Arizona withholding are applied.

• Weekly payroll usually uses 52 pay periods
• Biweekly payroll usually uses 26 pay periods
• Semimonthly payroll uses 24 pay periods
• Monthly payroll uses 12 pay periods

A biweekly paycheck and a semimonthly paycheck should not be treated as the same. Even when annual salary is identical, the gross amount per check and withholding pattern can differ.

How Pre-Tax Deductions Affect Arizona Withholding

Arizona defines gross taxable wages for withholding purposes as wages that generally correspond to federal Form W-2 box 1 wages. Pretax deductions such as an employee share of qualifying health insurance premiums can reduce gross taxable wages.

This means an A-4 percentage should be applied to the appropriate taxable wage amount, not necessarily the employee's unreduced gross compensation.

Overtime and Variable Pay in Arizona

Overtime, bonuses and commissions can increase the taxable wages for the current paycheck. The extra compensation should be added to gross pay before withholding is determined under the applicable federal and Arizona rules.

Variable pay can make one paycheck look very different from the employee's usual check even when the base hourly rate or salary has not changed.

Why YTD Wages Matter for Arizona Payroll

Year-to-date wages help the payroll calculation apply annual federal limits correctly. Social Security tax stops applying after the employee reaches the annual wage base, so a calculator that ignores prior wages can overstate Social Security on later checks.

YTD figures can also help employees review whether withholding changes during the year are producing the intended annual result.

Use the Calculator Before Creating the Pay Stub

A paycheck calculator estimates net pay. A pay stub records the completed payroll transaction. After the paycheck figures are verified, the Arizona pay stub generator can organize genuine earnings, state withholding, federal taxes, deductions and net pay.

Estimate Carefully When Payroll Is More Complex

Actual Arizona payroll can differ from a simplified estimate when there are multiple jobs, supplemental wages, garnishments, special benefit deductions, additional A-4 withholding or unusual federal Form W-4 elections. Local wage rules can also affect the gross-pay side of the calculation.

For a lawful payroll workflow, calculate wages first, verify withholding inputs then document the completed payroll. You can use the paystub generator after the payroll numbers have been confirmed.
