The IRS has some tips to help in the planning:
- Report changes in:
- Name. When a name changes through marriage, it is important to report that change to the Social Security Administration. The name on a person’s tax return must match what is on file at SSA. If it doesn’t, it could delay any 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.
- Address. 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. Notify the postal service to forward mail by going online at USPS.com or at a local post office.
- Consider changing withholding. Newly married couples must give their employers a new Form W-4, Employee's Withholding Allowance Certificate, within 10 days. If both spouses work, they may move into a higher tax bracket or be affected by the Additional Medicare Tax. Use the IRS Withholding Calculator at IRS.gov to help complete a new Form W-4. See Publication 505, Tax Withholding and Estimated Tax, for more information.
- Decide on a new filing status. Married people can choose to file their 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 a couple is married as of Dec. 31, the law says they’re married for the whole year for tax purposes.
