Use this tool to estimate the correct amount of tax your employer (W-2) or pension provider should withhold each year.
You can download a completed Form W-4 or Form W-4P and give it to your employer or pension provider. Depending on the results, this could help you avoid having too little tax withheld, making it less likely you’ll owe a penalty when you file your tax return. Or, it may help you avoid having too much tax withheld, giving you a bigger paycheck now but a smaller refund later.
Your most recent paystubs for your jobs, pensions, or annuities
Your spouse’s most recent paystubs for their jobs, pensions, or annuities (if you think you’ll file jointly)
If you have other sources of income or think you might itemize your deductions, you’ll also need:
Your most recent federal tax return
Payment records for self-employment, gig work, or Social Security
Records for expenses if you plan to itemize deductions or claim adjustments
What to expect
To estimate your federal tax withholding, we’ll ask you about:
You and your spouse, if you have one
Your income
Any adjustments, deductions, or credits you think you might claim
This should take about 25 minutes. If you’re not sure how to answer, we’ll help you along the way.
The estimator doesn’t ask for personal information such as your name, Social Security number, address, or bank account numbers. Your information won’t be saved or shared with the IRS. If you close your browser window, your responses will be cleared.
When to check your withholding
Check your withholding every January to make sure it’s correct for the year. This helps you prevent an unexpected tax bill, avoid penalties, and maximize your take-home pay.
You should also check your withholding when you have a major life change, including:
New job or other paid work
Major income change
Marriage, divorce, or separation
Child birth or adoption
Home purchase
If you change your withholding during the year, you may need to update it again in late December to withhold the right amount next year.
After you use the estimator
If you decide to change your tax withholding, you can use your estimate to generate a pre-filled Form W-4 or Form W-4P. This form helps you update your tax withholding with your employer, pension provider, or their payroll or human resource system.
