What FICA taxes does this calculator cover?

It covers Social Security (6.2% on wages up to $168,600 in 2024), Medicare (1.45% on all wages), and the 0.9% Additional Medicare surtax for high earners.

Are state taxes included?

No. This tool covers federal taxes only — federal income tax withholding plus FICA. State income tax rates vary widely by state and are not included. Add your state's withholding separately.

How accurate is the federal income tax estimate?

The estimate uses the 2024 IRS Publication 15-T percentage method tables and annualizes wages to determine the marginal bracket, then de-annualizes the result. It is a close approximation — actual withholding can differ slightly depending on Form W-4 elections and employer payroll software rounding.

What is the Additional Medicare Tax?

Employers withhold the 0.9% Additional Medicare Tax after wages they pay an employee exceed $200,000 in the calendar year, regardless of filing status. The employee's final tax threshold depends on filing status and is reconciled on the tax return; employers do not match this tax.

Does this include unemployment taxes (FUTA/SUTA)?

No. FUTA (Federal Unemployment Tax Act) and SUTA (state unemployment) are not included because they depend on each employer's state, industry, and experience rating. FUTA is typically 0.6% on the first $7,000 of wages after state credits.
