What is the difference between marginal and effective tax rate?

Your marginal rate is the rate on your last dollar. Your effective rate is total tax divided by gross income, always lower because progressive brackets apply incrementally.

How Does a 401(k) Reduce Your Taxes?

A traditional 401(k) is a pre-tax deduction - it lowers your taxable income before federal and state taxes are calculated. If you earn $70,000 and contribute $7,000, you only pay income tax on $63,000. The 2026 limit is $24,500 (under 50) or $32,500 (age 50+).

Note: 401(k) contributions still have Social Security (6.2%) and Medicare (1.45%) applied. Health insurance premiums paid through a Section 125 plan are exempt from all payroll taxes, making them even more tax-efficient.

Frequently Asked Questions

How does a 401(k) reduce my taxes? +

Traditional 401(k) contributions reduce your taxable income dollar for dollar. If you earn $60,000 and contribute $6,000, you only pay income tax on $54,000. This lowers your federal and state income tax but not Social Security or Medicare taxes. The 2026 limit is $24,500 under 50.

Which states have no income tax? +

Nine states have no income tax in 2026: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. Residents keep significantly more of their paycheck compared to high-tax states like California (9.3%) or Oregon (8.75%).

What is marginal vs effective tax rate? +

Your marginal tax rate is the rate on your last dollar of income (e.g. 22%). Your effective tax rate is total tax divided by gross income - always lower because progressive brackets apply incrementally. This calculator shows both.

How is take-home pay calculated? +

Take-home = Gross salary minus pre-tax deductions (401k, health, HSA) minus federal income tax minus Social Security (6.2%) minus Medicare (1.45%) minus state income tax. Pre-tax deductions reduce taxable income before income tax is applied.

Why does my actual paycheck differ? +

Your paycheck may differ due to local city taxes, additional W-4 withholdings, Roth 401(k) contributions (post-tax), or employer-specific payroll calculations. This calculator provides a reliable baseline estimate based on standard federal and state rates.

Is this a payroll tax calculator? +

Yes — this calculator functions as a full payroll tax calculator, combining federal income tax, state income tax, and FICA (Social Security and Medicare) into one take-home pay estimate for all 50 states. If you only want to estimate your federal withholding based on your W-4, use the Tax Withholding Calculator instead.

Can I use my W-2 with this calculator? +

This calculator projects your take-home pay forward from your salary, rather than working backward from a W-2. To sanity-check a past year, compare Box 1 of your W-2 (taxable wages) and Box 2 (federal tax withheld) against the federal tax figure this calculator shows for the same gross salary and filing status.
