Frequently asked questions
Is a deduction the same as a tax credit?
No. A deduction generally reduces taxable income. A credit can reduce tax directly. This calculator only estimates deduction savings.
What tax rate should I enter?
Use an estimated marginal tax rate. If unsure, use this as a rough planning example and review the result with a qualified tax professional.
Why might the actual savings be different?
Actual savings can change because of the standard deduction, itemized deductions, income limits, credits, phaseouts, state rules, and other tax calculations.
