Tax Withholding Estimator

The Tax Withholding Estimator is an online tool provided by the U.S. Internal Revenue Service (IRS) to help taxpayers calculate and estimate the amount of federal income tax that should be withheld from their paychecks. It is designed to assist individuals in ensuring that they have the correct amount of income tax withheld throughout the year, so they do not owe a large tax bill or receive a substantial refund when they file their annual income tax return.
