Use new W-4 to change your tax withholding
Form W-4 is used to let your employer know how much federal income tax to withhold from your pay. The IRS recommends completing a new Form W-4 when your personal or financial situation changes. This year, the IRS redesigned Form W-4 to reduce complexity and improve accuracy. Go to the IRS website for information about Tax Withholding, FAQs on the 2020 Form W-4, and a Tax Withholding Estimator.
