Tax Withholding Estimator

Use your best estimates for the year ahead to determine how to complete Form W-4 so you don’t have too much or too little federal income tax withheld.

If you are an employee, the withholding calculator can help you determine weather you need to give your employer a new Form W-4, Employee’s Withholding Allowance Certificate to avoid having too much or too little Federal income tax withheld from your pay.

Remember, the Withholding Calculator does not ask the user for personally identifiable information, such as name, social security number, address, or bank account numbers. The IRS does not save or record the information the taxpayer enters in the calculator.

While it’s a good idea for everyone to check their withholding, it’s especially important for these people to use the Withholding Calculator to make sure they have the right amount of tax withheld:

    1. Two-income families
    2. People with two or more jobs at the same time or who only work for part of the year
    3. People who claim credits such as the Child Tax Credit
    4. People who claim older dependents, including children age 17 or over
    5. People who itemized deductions in 2017
    6. People with high incomes and more complex tax returns
    7. People with large tax refunds or large tax bills for 2017
