Introduction
Federal income tax is taken out of your paycheck before you ever see the money. This is called withholding. If too much is withheld, you get a refund. If too little is withheld, you owe the IRS when you file your tax return. Either way, it helps to know where you stand before the year ends.
This free IRS Withholding Calculator helps you figure out if you are having the right amount of federal tax taken from your pay. Just enter your income, filing status, deductions, and credits. The tool will estimate your total tax for the year and compare it to what has already been withheld. It then shows you whether you can expect a refund or a balance due and suggests how much to withhold from each remaining paycheck to come out close to even.
Use this calculator any time during the year, especially after a major life change like getting married, having a child, or starting a new job. Checking your withholding now can help you avoid a surprise tax bill or a large refund that could have been in your pocket all along.
How to Use Our IRS Withholding Calculator
Enter your income, tax withholding, and filing details below. The calculator will tell you if you are on track for a refund or if you may owe money at tax time.
Age 65 or Older: Pick "Yes" if you will be 65 or older by January 1st of the tax year. This gives you a bigger standard deduction.
Blind: Pick "Yes" if you are legally blind. This also adds to your standard deduction.
Claiming Dependents: Pick "Yes" if you support a child or other person who qualifies as your dependent. This unlocks the Child Tax Credit and Other Dependents Credit fields.
Claimed as a Dependent: Pick "Yes" if someone else, like a parent, claims you on their tax return. This limits your standard deduction.
Filing Status: Choose the status that fits you — Single, Married Filing Jointly, Married Filing Separately, Head of Household, or Qualifying Surviving Spouse.
Lived with Spouse (MFS only): If you file Married Filing Separately, tell us if you and your spouse lived together at any point during the year. This affects your credits.
Spouse Information: If you file jointly, enter whether your spouse is 65 or older, blind, or claimed as a dependent by someone else.
Annual Wages / Salary: Enter your total gross pay for the year before any taxes or deductions come out. If filing jointly, also enter your spouse's wages. If you want to understand the difference between your gross and net figures, our Salary Calculator can help break that down.
Other Taxable Income: Enter any other income you expect this year, such as interest, dividends, or freelance pay. If you earn dividend income, our Dividend Calculator can help you estimate those amounts.
Federal Tax Withheld So Far: Look at your most recent pay stub. Enter the total federal income tax taken out of your pay so far this year.
Tax Withheld Each Remaining Pay Period: Enter the federal tax amount taken from each future paycheck for the rest of the year.
Remaining Pay Periods: Enter how many more paychecks you expect to get this year.
Traditional 401(k) / 403(b) Contributions: Enter the total amount you put into a traditional 401(k) or 403(b) plan this year. This lowers your taxable income. To see how those contributions grow over time, try our 401k Calculator.
Deductible IRA / HSA / Student Loan Interest: Enter any deductible IRA or HSA contributions and student loan interest you paid. These also lower your taxable income. If you contribute to an HSA, our HSA Calculator can help you plan your contributions.
Deduction Method: Pick "Standard" to use the IRS standard deduction or "Itemize" to enter your own total. The calculator will use whichever amount is larger.
Total Itemized Deductions: If you chose to itemize, enter your total. This includes things like mortgage interest, state taxes paid, and charitable donations.
Qualifying Children Under 17: Enter the number of children under age 17 who qualify for the Child Tax Credit. Each child is worth up to $2,000.
Other Dependents: Enter the number of other dependents who do not qualify for the Child Tax Credit. Each one is worth up to $500.
Other Tax Credits: Enter any other credits you expect, such as education credits or the earned income credit.
Calculate Button: Press "Calculate" to see your results. You will get your estimated refund or amount owed, a full tax summary, a chart comparing your withholding to your tax bill, and a suggestion for how much to withhold per paycheck to break even.
What Is Federal Tax Withholding?
Every time you get a paycheck, your employer takes out a portion of your pay and sends it to the IRS. This is called federal tax withholding. It is how most workers pay their income taxes throughout the year instead of paying one big bill in April. The amount withheld depends on your filing status, how much you earn, and the choices you made on your W-4 form.
Why Your Withholding Amount Matters
If too much money is withheld, you get a refund when you file your tax return. That might sound nice, but it means you gave the government an interest-free loan all year. If too little is withheld, you will owe money at tax time and could face a penalty. The goal is to get your withholding as close to your actual tax bill as possible so you keep more of your money in each paycheck without owing a surprise bill later. You can use our Take Home Pay Calculator to see how different withholding amounts affect the cash you actually receive.
How This Calculator Helps
This IRS withholding calculator estimates your total federal income tax for the year based on your wages, filing status, dependents, deductions, and credits. It then compares that tax bill to how much has already been withheld from your paychecks plus what will be withheld for the rest of the year. The result tells you whether you are on track for a refund or if you might owe money. It also suggests how much you should withhold per remaining pay period to break even.

Key Terms to Know
Filing status is how you identify yourself on your tax return — single, married filing jointly, married filing separately, head of household, or qualifying surviving spouse. Your filing status affects your tax brackets and standard deduction.
Standard deduction is a flat dollar amount the IRS lets you subtract from your income before calculating tax. Most people use the standard deduction because it is simple and often larger than itemized deductions. If you are claimed as a dependent by someone else, your standard deduction is limited based on your earned income.
Tax credits directly reduce the amount of tax you owe. The Child Tax Credit gives up to $2,000 per qualifying child under 17. The Credit for Other Dependents gives up to $500 per dependent who does not qualify for the Child Tax Credit. These credits phase out at higher income levels.
Adjusted gross income (AGI) is your total income minus above-the-line adjustments like 401(k) contributions, IRA deductions, and student loan interest. Your AGI determines whether you qualify for certain credits and deductions. Our MAGI Calculator can help you estimate your modified adjusted gross income, which is used for additional eligibility tests.
When to Check Your Withholding
You should check your withholding at least once a year. It is especially important to check after major life changes like getting married, having a baby, buying a home, starting a new job, or getting a raise. Any of these events can change how much tax you owe and whether your current withholding is enough. If you are also self-employed or earn freelance income, our Self Employment Tax Calculator can help you estimate the additional taxes you may owe. You can also use the Effective Tax Rate Calculator to understand what percentage of your income actually goes toward taxes, and our Paycheck Calculator to see a full breakdown of each paycheck. If you receive a bonus, check our Bonus Tax Calculator to see how supplemental wages are taxed. Planning for retirement contributions that affect your withholding?
