Predict your end-of-year tax liability and refund/balance due based on your W-4 settings.
Crucial Context: This tool focuses on W-4 accuracy to predict end-of-year tax liability and refunds, rather than just calculating take-home pay. Standard paycheck calculators show your next check; this tool shows you if you're on track for April 15th.
Enter your income and W-4 settings to see your projected tax refund or balance due.

This tool models your W-4 entries to project how much federal and state tax will be removed from each paycheck. It ensures you are paying the correct amount of tax throughout the year without overpaying.
Anyone starting a new job, experiencing a life change like marriage or a new child, or dealing with a massive tax refund or bill from the previous year. It perfectly complements our US paycheck calculator.
Example Input
Single earner, $75,000 salary, recently had a child and needs to update their W-4.
Sample Output
By claiming the $2,000 Child Tax Credit on the W-4, the paycheck withholding decreases, putting roughly $166 more back into their monthly take-home pay.
Example Input
Spouse 1 earns $90,000, Spouse 2 earns $60,000. Both claim standard withholding.
Sample Output
Without checking the 'two jobs' box, they will under-withhold by $3,500. Adjusting the W-4 ensures proper taxes are taken out to avoid a penalty at tax time.
Use this tool to dial in your take-home pay. A $3,600 tax refund means you gave the government a $300/month interest-free loan. You could have been investing that money and watching it grow with our compound interest calculator.
Input accurate estimates for your total annual income, spouse's income, and expected deductions. If you are a high earner, consider how contributions modeled in our 401k calculator will lower your taxable baseline.
Failing to account for a spouse's income or a side hustle can lead to severe under-withholding and IRS penalties. Read our guide on US federal tax brackets to understand how additional income pushes your top dollars into higher tax tiers.
The modern W-4 no longer uses 'allowances' like 0 or 1. Instead, you directly input dollar amounts for dependents and deductions to calculate precise withholding.
You likely under-withheld from your paychecks. This often happens if you have a second job, a working spouse, or untaxed side income and didn't account for it on your W-4.
Ideally, no. A large refund means you overpaid taxes all year. It is usually better to get that money in your paychecks to invest, save, or pay down debt.
Calculations run locally in your browser (compatible with modern versions of Chrome, Safari, Edge, Firefox). The tool does not connect to bank or investment accounts; review the Privacy Policy because standard site services may still make network requests.
