Take Home Pay = Gross Pay – (Federal Tax + State Tax + FICA + Other Deductions)
Let’s break it down:
- Gross Pay: Total income before deductions.
- Federal Tax: Calculated using current IRS tax brackets.
- State Tax: Arizona’s flat income tax rate of 2.5% (since 2023).
- FICA: Fixed at 7.65% of your gross pay (6.2% Social Security + 1.45% Medicare).
- Other Deductions: Includes health insurance, retirement contributions, or garnishments.
💡 Example Calculation
Let’s say you earn $70,000 annually, live in Arizona, and are single with standard deductions.
Step 1: Gross Monthly Pay
$70,000 ÷ 12 = $5,833.33 per month
Step 2: Federal Income Tax
Approx. $600/month (based on IRS tables for 2025).
Step 3: FICA Taxes
7.65% × $5,833.33 = $446.46
Step 4: Arizona State Tax
2.5% × $5,833.33 = $145.83
Step 5: Take Home Pay
$5,833.33 – ($600 + $446.46 + $145.83) = $4,640.99
✅ Your estimated monthly take-home pay is $4,640.99

💰 Arizona State Tax Breakdown
Arizona switched to a single flat income tax rate of 2.5% in 2023. This makes it one of the simplest and lowest state income tax systems in the U.S. Before this change, taxpayers had to navigate multiple brackets ranging from 2.59% to 4.5%, but now every resident pays the same rate.
This flat rate simplifies paycheck calculations, making the Arizona ADP Calculator especially accurate and user-friendly.

- Pre-tax Deductions – Contributions to 401(k), HSA, or insurance reduce taxable income.

✅ Key Formula Summary (Plain Text)
- Federal Tax (approximate):
Based on IRS tax brackets and standard deductions. - FICA (Social Security + Medicare):
7.65% × Gross Income - Arizona State Tax:
2.5% × Taxable Income - Take Home Pay:
Gross Income – (Federal Tax + State Tax + FICA + Deductions)
📘 Example (Biweekly Pay)
Let’s say your gross annual income is $52,000.
- Biweekly pay = 52,000 ÷ 26 = $2,000 per period
- Federal tax ≈ $210
- FICA = 7.65% × 2,000 = $153
- Arizona tax = 2.5% × 2,000 = $50
Take Home Pay = $2,000 – ($210 + $153 + $50) = $1,587
Your biweekly net pay is about $1,587.
