How Is Your Tax Refund
Actually Calculated?
A tax refund happens when the total amount withheld from your paychecks during the year exceeds your actual tax liability. The math is simple: total tax withheld (from your W-2) minus your actual tax liability equals a refund if positive, or an amount owed if negative.
Your actual liability depends on your taxable income — gross income minus either the standard deduction or itemized deductions. Filing status matters too: married filing jointly gets wider tax brackets and a larger standard deduction than single filers. Tax credits then reduce your bill dollar for dollar — the Earned Income Tax Credit alone can be worth over $7,000 for qualifying families, and the Child Tax Credit adds up to $2,000 per child.

Frequently Asked Questions
Is Tax47 really free?
Yes — you can build a full tax return and see your estimated refund without paying anything or creating an account. There's an optional premium upgrade for managing multiple saved returns and extra themes, but the entire calculation experience is free for one return.
Where does my tax data live?
On your device. Nowhere else. Every calculation runs on-device — your income, filing status, and results are never transmitted to our servers or anyone else.
Which tax year does it cover?
Tax47 supports the 2024, 2025, and 2026 tax years and compares them side by side, so you can see exactly how the new One Big Beautiful Bill (P.L. 119-21) changes affect your refund.
Can it handle self-employment income?
Yes. Add a Schedule C and Tax47 computes self-employment tax, the deductible half, the QBI deduction, and four quarterly estimated-payment amounts with their due dates.
Does it cover the new 2026 deductions?
Yes. The new tips deduction, overtime deduction, car loan interest deduction, and senior bonus deduction from the One Big Beautiful Bill all surface automatically when they apply to your return.
Is this a substitute for filing my taxes?
No. Tax47 gives you an accurate estimate to plan with — it is not tax advice and is not a filing tool. Always confirm with a qualified tax professional or the IRS before you file.
