Taxes and Tying the Knot


If you're planning on tying the know, here are some helpful tax tips:
  • Name change: The names and Social Security numbers on your tax return must match your Social Security Administration records. If you change your name, report it to the SSA. To do that, file Form SS-5, Application for a Social Security Card. You can get the form on www.gsa.gov, by calling 800-772-1213 or from your local SSA office.
  • Change tax withholding: A change in your marital status means you must give your employer a new Form W-4, Employee's Withholding Allowance Certificate. If you and your spouse both work, your combined incomes may move you into a higher tax bracket. Use the IRS Withholding Calculator tool at IRS.gov to help you complete a new Form W-4. See Publication 505, Tax Withholding and Estimated Tax, for more information.
  • Changes in circumstances: If you receive advance payment of the premium tax credit in 2014, it is important that you report changes in circumstances, such as changes in your income or family size, to your Health Insurance Marketplace. You should also notify the Marketplace when you move out of the area covered by your current Marketplace plan. Advance payments of the premium tax credit provide financial assistance to help you pay for the insurance you buy through the Health Insurance Marketplace. Reporting changes will help you get the proper type and amount of financial assistance so you can avoid getting too much or too little in advance.
  • Address change: Let the IRS know if your address changes. To do that, file Form 8822, Change of Address, with the IRS. You should also notify the U.S. Postal Service. You can ask them online at USPS.com to forward your mail. You may also report the change at your local post office.
  • Change in filing status: If you're married as of Dec. 31, that's your marital status for the whole year for tax purposes. You and your spouse can choose to file your federal income tax return either jointly or separately each year. You may want to figure the tax both ways to find out which status results in the lowest tax.
  • Note for same-sex married couples: If you are legally married in a state or country that recognizes same-sex marriage, you generally must file as married on your federal tax return. This is true even if you and your spouse later live in a state or country that does not recognize same-sex marriage. See irs.gov for more information on this topic.

Deductions and Credits You Should Be Aware of If You Have Children

  1. Dependents. In most cases, you can claim your child as a dependent. This applies even if your child was born on the last day of the calendar year, December 31.
  2. Child Tax Credit. You may be able to claim the Child Tax Credit for each of your qualifying children under the age of 17 at the end of 2013. The maximum credit is $1,000 per child. If you get less than the full amount of the credit, you may be eligible for the Additional Child Tax Credit. See the instructions for Schedule 8812, Child Tax Credit, and Publication 972, Child Tax Credit.
  3. Child and Dependent Care Credit. You may be able to claim this credit if you paid someone to care for one or more qualifying persons. Your dependent child or children under age 13 are among those who are qualified. You must have paid for care so you could work or look for work. See Publication 503, Child and Dependent Care Expenses.
  4. Earned Income Tax Credit. If you worked but earned less than $51,567 last year, you may qualify for EITC. If you have three qualifying children, you may get up to $6,044 as EITC when you file and claim it on your tax return. Use the EITC Assistant tool at IRS.gov to find out if you qualify or see Publication 596, Earned Income Tax Credit.
  5. Adoption Credit. You may be able to claim a tax credit for certain expenses you paid to adopt a child. For details, see the instructions for Form 8839, Qualified Adoption Expenses.
  6. Higher education credits. If you paid for higher education for yourself or an immediate family member, you may qualify for either of two education tax credits. Both the American Opportunity Credit and the Lifetime Learning Credit may reduce the amount of tax you owe. If the American Opportunity Credit is more than the tax you owe, you could be eligible for a refund of up to $1,000. See Publication 970, Tax Benefits for Education.
  7. Student loan interest. You may be able to deduct interest you paid on a qualified student loan, even if you don’t itemize deductions on your tax return. For more information, see Publication 970.
  8. Self-employed health insurance deduction. If you were self-employed and paid for health insurance, you may be able to deduct premiums you paid to cover your child under the Affordable Care Act. It applies to children under age 27 at the end of the year, even if not your dependent. See Notice 2010-38 for information.
