RELATED: The IRS Just Gave This Urgent Last-Minute Warning to Taxpayers. The IRS posted a new warning for taxpayers on April 13, advising them to check their tax withholding once they’re done with this year’s tax return. According to the tax agency, doing this will allow you to make sure you’re “having the right amount of tax taken out” of your pay in 2022.ae0fcc31ae342fd3a1346ebb1f342fcb “The IRS recommends checking withholding at least once a year. For anyone who has just finished filling out their 2021 return, now is a particularly good time to do it,” the agency said. “It’s also a good idea to use this tool right after a major life change, such as marriage, divorce, home purchase or the birth or adoption of a child.” You should use the online Tax Withholding Estimator to calculate the amount of federal income tax being taken out of your paycheck, according to the IRS. To use this tool, the agency recommends that you gather your most recent pay statement (and those for your spouse, too, if you’re married), information for other sources of income, and your most recent income tax return. Without this, your estimated amount might not come out correctly. “The Tax Withholding Estimator’s results are only as accurate as the information entered,” the IRS warned.

If your 2021 refund was smaller or bigger than you expected, or you received a tax bill you weren’t expecting this year, the IRS said that using the Tax Withholding Estimator can help “make sure it doesn’t happen again” next tax season. The tool will estimate your federal income tax withholding and then show you how your refund, take-home pay, or owed taxes would be affected by your withholding amount. If you want to change how much tax you’re withholding from each paycheck after using the estimator, you can complete a new Form W-4 and submit it to your employer. “Checking withholding can ensure the right amount of tax is withheld and prevent an unexpected tax bill or penalty at tax time and determine whether to have less tax withheld up front, thereby boosting take-home pay and reducing any refund at tax time,” the IRS explained. While the Tax Withholding Estimator should work for most taxpayers, the IRS does advise some people not to use the tool. This includes taxpayers who have a pension but not a job and those who have nonresident alien status. Both of these groups should use other forms indicated on the agency’s website. And if your tax situation is “more complex” than the average person’s, the agency said you should use the instructions in its Publication 505 instead to calculate your withholding amount. “This includes taxpayers who owe alternative minimum tax or certain other taxes, and people with long-term capital gains or qualified dividends,” the IRS explained.
