Bi‑Weekly Paycheck Tax Calculator 2026 – Net Pay Estimator
Introduction
Most US employees are paid bi‑weekly. This guide shows how to estimate your net paycheck by modeling W‑4 settings, pretax benefits, and federal/state/FICA taxes.
What You’ll Need
- Annual salary or hourly × expected hours
- Filing status and state
- W‑4 selections
- 401(k)/HSA/FSA amounts; insurance premiums
Steps
- Enter salary and pay frequency (bi‑weekly)
- Add pretax contributions and premiums
- Choose state and filing status
- View federal, state, Social Security, and Medicare breakdowns
Examples (Illustrative)
- $75,000 salary, 10% 401(k) → net ≈ $2,200–$2,400 depending on state
- Add HSA $150/paycheck → reduces taxable income and increases long‑term savings
W‑4 Deep Dive (2026)
Your W‑4 determines withholding accuracy per paycheck.
- Step 1: Filing status (Single, MFJ, HOH)
- Step 2: Multiple jobs/working spouse (check if applicable)
- Step 3: Dependents (child/other credits)
- Step 4(a): Other income not from jobs; 4(b): Deductions if itemizing; 4(c): Extra withholding
Tips:
- Use the IRS Withholding Estimator mid‑year to course‑correct
- Large refunds mean over‑withholding; balances due mean under‑withholding
FICA and Thresholds
- Social Security: 6.2% up to the annual wage base (illustrative)
- Medicare: 1.45% on all wages; +0.9% Additional Medicare Tax over thresholds
- These are per‑employee; employers match separately
State and Local Notes
- Some states have no income tax; others use flat or progressive rates
- Certain cities/locals add withholding (e.g., municipal taxes)
- Use the state selector in the calculator to preview variations
More Bi‑Weekly Scenarios
- $60k, Single, 5% 401(k) → modest tax savings with manageable net
- $120k, MFJ, 10% 401(k) + HSA $150/paycheck → higher savings, sizable tax reduction
- $90k, HOH, no pretax benefits → higher taxable income; consider starting 401(k)/HSA
