Compare what you owe against what has already been withheld to see whether you are due a refund or a bill.
How the tax refund calculator works
A refund is not a bonus — it is the return of tax you overpaid during the year. This calculator works out your actual liability from your income and filing status, then subtracts what your employer already sent to the IRS.
A large refund means your withholding is set too high; a large bill means it is set too low. Either way, adjusting your W-4 brings the two closer together.
How to fill it in
- Enter your gross income and the federal tax already withheld.
- Choose your filing status and tax year.
- Add any tax credits you expect to claim.
The formula
liability = bracket tax on (income − pre-tax − deduction) − credits
refund = tax withheld − liability
The default scenario, worked through
On the values this calculator opens with, the estimated refund is $1,226. Underneath, Taxable income comes out at $53,000 and Tax before credits at $6,574. Change any field and every figure updates as you type.
Frequently asked questions
Why is my refund smaller this year?
Common causes are a raise that moved you into a higher bracket, a change in withholding, or credits that expired or phased out at your income.
Are credits the same as deductions?
No. A deduction reduces taxable income; a credit reduces the tax itself dollar for dollar, so credits are worth considerably more.
How fast are refunds paid?
Electronically filed returns with direct deposit are usually processed within a few weeks, though returns claiming certain credits are held longer by law.
