Tax Checklist for Newlyweds
April 10, 2026 by Mitch Gwost

Summer is a popular season for weddings, and newlyweds can make tax filing easier by taking a few simple steps now. Remember, your marital status as of December 31 determines your tax filing options for the entire year—but that’s just one important detail for newlyweds to consider.

Report a name change

 Report any name changes to the Social Security Administration. The name on a person’s tax return must match what’s on file at the SSA. Otherwise, it could delay any tax refund. Taxpayers should file Form SS-5, Application for a Social Security Card with their updated information. It’s available on SSA.gov, by phone at 800-772-1213 or at a local SSA office.

Update address

 Notify their local post office, employers and the IRS of any address change. To officially change their mailing address with the IRS, taxpayers must compete and submit Form 8822, Change of Address. See page 2 of the form for detailed instructions.

Check withholding

 Newly married couples must give their employers a new Form W-4, Employee’s Withholding Certificate, within 10 days. If both people work, this could move them into a higher tax bracket or be affected by the additional Medicare tax. The Tax Withholding Estimator on IRS.gov can be used to check withholding and provide tips for completing a new Form W-4.

Review filing status

 Married people can choose to file their federal income taxes jointly or separately. While filing jointly is usually more beneficial, it’s best to figure the tax both ways to find out which makes the most sense.

“Taking care of name changes, updating your address, and reviewing your tax withholding after getting married can prevent delays and unnecessary surprises at tax time. It’s always a good idea for newlyweds to review their tax situation early and reach out to a professional with any questions.”
