Calculation Methodology

Nevada state tax

Nevada does not impose individual income tax. State tax withholding is always $0 for W-2 and 1099 workers.

Federal income tax

We annualize per-period gross pay, subtract pre-tax deductions and the standard deduction, apply 2026 progressive brackets, then adjust for W-4 inputs (dependents credit, other income, deductions, extra withholding). Legacy W-4 uses allowance values of $4,700 each.

FICA

• Social Security: 6.2% up to $184,500 annual wages
• Medicare: 1.45% on all wages
• Additional Medicare: 0.9% above filing-status thresholds
• Pre-tax deductions do not reduce FICA wages in this calculator

Bonus withholding

Flat method uses 22% supplemental rate. Aggregate method taxes bonus with regular wages using the standard federal calculation.

Self-employment tax

15.3% on 92.35% of net profit (12.4% Social Security up to wage base + 2.9% Medicare). Half of SE tax is deducted before federal income tax.
