How your take-home pay is calculated
Take-home = Gross pay − 401(k) − health − HSA − federal income tax − Social Security − Medicare − Arizona income tax − local tax
Federal income tax uses the 2026 brackets and standard deduction. Social Security is 6.2% of pay up to $184,500 a year; Medicare is 1.45% of all pay plus 0.9% above $200,000. Pre-tax health and HSA payroll deductions lower all of these; 401(k) lowers income tax only.
Arizona take-home pay examples
Single filer, paid every two weeks, no 401(k) or other pre-tax deductions, no local tax:
| Salary | Federal tax | Social Security + Medicare | State income tax | Take-home a year | Per biweekly check |
|---|---|---|---|---|---|
| $50,000 | $3,820.00 | $3,825.00 | $1,041.25 | $41,313.75 | $1,588.99 |
| $75,000 | $7,670.00 | $5,737.50 | $1,666.25 | $59,926.25 | $2,304.86 |
| $100,000 | $13,170.00 | $7,650.00 | $2,291.25 | $76,888.75 | $2,957.26 |
Worked example, $75,000 salary:
- Federal: $75,000 − $16,100 standard deduction = $58,900 taxable. Tax = $1,240 + $4,560 + 22% × $8,500 = $7,670.00.
- Social Security 6.2% = $4,650.00. Medicare 1.45% = $1,087.50.
- Arizona taxable income $66,650.00, Arizona income tax $1,666.25.
- Take-home: $59,926.25 a year, or $2,304.86 every two weeks. That's 20.1% of pay in taxes.
What this calculator simplifies
- Tax is worked out for the whole year and spread evenly over your paychecks. Employers use withholding tables, so a real check can differ by a few dollars; you settle the difference when you file.
- Federal tax uses the 2026 standard deduction only. Dependents, itemized deductions and the new tips, overtime and senior deductions aren't included (W-4 Step 3 credits can be entered under More options).
- State tax covers a typical W-2 employee who lives and works in the state. State credits for dependents, renters, earned income and similar aren't included.
- Head of household and married filing separately use Arizona's single amounts.
