Marriage changes many things and taxes is one of them. Newlyweds should know how tying the knot can affect their tax situation.

Here’s a tax to-do-list for newly married couples:

Name and address changes

• When a name changes through marriage, it is important to report that change to the Social Security Administration. The name on your tax return must match what is on file at the SSA. If it doesn’t, it could delay any tax refund. To update information, file Form SS-5, Application for a Social Security Card. It is available on SSA.gov, by calling 800-772-1213, or at a local SSA office.
• If marriage means a change of address, the IRS and U.S. Postal Service need to know. To do that, send the IRS Form 8822,Change of Address. Also notify the postal service by going online at USPS.com or visit your local post office.

Withholding

After getting married, you should consider changing your withholding. Newly married couples must give their employers a new Form W-4, Employee’s Withholding Allowance within 10 days. If you both work, you may move into a higher tax bracket or be affected by the additional Medicare tax. You can use the Tax Withholding Estimator on IRS.gov to help complete a new Form W-4. You can review Publication 505,Tax Withholding and Estimated Tax for more information.

Filing status

You can choose to file your federal income taxes jointly or separately each year. While filing jointly is usually more beneficial, it’s best to figure the tax both ways to find out which works best. Remember, if you are married as of December 31, the law says you’re married for the whole year for tax purposes.
