Common Questions

Does the income tax calculator include state taxes?

No. It estimates federal income tax only. State and local taxes vary widely, so add those separately for a complete take-home estimate.

Why are marginal and effective tax rates different?

The marginal rate applies to the next dollar of taxable income. The effective rate is total federal tax divided by total income, so it is usually lower.

Can freelancers use these tax calculators?

Yes. Start with the self-employment tax calculator for Social Security and Medicare taxes, then use the income tax calculator to estimate federal income tax.
