Methodology

How This Estimate Works

About this calculator

This calculator estimates the 2025 federal income tax, Social Security and Medicare (FICA) tax, and state income tax on wage income. It uses your income, state, filing status, deduction choice, and pre-tax retirement contributions.

How the estimate is built

  1. We start with your household income and subtract your pre-tax 401(k) and traditional IRA contributions.
  2. We subtract the 2025 standard deduction for your filing status, or your itemized total if you enter one, to reach federal taxable income.
  3. We run that taxable income through the 2025 IRS brackets for your filing status. Each rate applies only to the income inside its bracket.
  4. We add FICA: 6.2% Social Security on wages up to $176,100, 1.45% Medicare on all wages, and 0.9% Additional Medicare Tax on wages above your filing status’s threshold. Retirement contributions do not lower FICA.
  5. We apply your state’s 2025 brackets, standard deduction, and personal exemption or credit, and subtract retirement contributions only where your state allows it.

Rate updates. Rates come from IRS and state revenue department publications and are reviewed each year. Last reviewed October 8, 2026.

Assumptions and limits
  • All income is treated as W-2 wages. Self-employment, investment, retirement, and Social Security income are not modeled.
  • Local, county, and city income taxes are not included.
  • Tax credits, dependents, and the 2025 deductions for tips, overtime, and seniors are not included.
  • Traditional IRA contributions are treated as fully deductible, and catch-up contributions for age 50 and older are not modeled.
  • Every state uses its standard deduction, and state phase-outs, recapture rules, and minimum taxes for higher incomes are ignored. Ohio, Connecticut, Alabama, Arkansas, Utah, and Oregon are the states most affected.
  • Results are rounded to the nearest dollar.

FAQ's

Income Tax Calculator Questions

What is the difference between a marginal and an effective tax rate?

Your marginal rate is the rate on your next dollar of income, the top bracket you reach. Your effective rate is your total tax divided by your total income. Because U.S. income tax is progressive, your effective rate is always lower than your marginal rate.

What is the 2025 standard deduction?

For 2025, the federal standard deduction is $15,750 for single filers and married couples filing separately, $23,625 for heads of household, and $31,500 for married couples filing jointly.

Does a 401(k) contribution lower my taxes?

Pre-tax 401(k) contributions lower your federal income tax and, in most states, your state income tax. They do not lower Social Security and Medicare (FICA) taxes. Pennsylvania is one state that taxes 401(k) contributions.

Which states have no income tax on wages?

Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming do not tax wage income. Washington taxes some capital gains.

How accurate is this calculator?

It is an estimate for wage income using 2025 federal and state rates. It leaves out local taxes, credits, and some deductions, so your actual return may differ. For advice on your situation, talk to a tax professional.

What if I owe more than I can pay?

File on time anyway, because the failure-to-file penalty is much larger than the failure-to-pay penalty. The IRS and most states offer payment plans and other relief, and eligibility depends on your facts. We review your situation for free.
