COMMON QUESTIONS

Before you calculate

Some important things to know before using an online tax estimate.

Are these tax calculators free?

The calculators on FreeTaxCalculator.us are intended to be free to use. Each tool should explain the information it requires and any important limitations.

Does this estimate include state income tax?

No. The homepage estimator estimates simplified federal individual income tax only. It does not calculate state or local taxes, Social Security and Medicare payroll taxes, or all possible additional taxes.

Is this the amount of my tax refund?

No. A refund estimate generally requires information about tax payments, withholding, credits, and other tax-return details. This homepage tool does not calculate a refund.

Can I use this result to file my tax return?

No. This is an educational estimate, not tax preparation or filing software. Confirm your circumstances against current official guidance or consult a qualified tax professional.

How often should tax calculations be updated?

Calculations should be reviewed when tax-year brackets, deductions, thresholds, laws, or official guidance change. Check the tax year and assumptions shown on each tool.
