Newlyweds can suddenly become ineligible for Roth IRAs once their incomes are combined, although couples may still invest in them indirectly. Getty Images By Kimberly Lankford, Contributing Editor August 25, 2017 QI'm getting married next month, and when we add up my income and my wife's, we'll earn more than the limit to contribute to a Roth IRA. But I'm below the income limit now, so can I contribute to a Roth before the wedding?ANo. If you're married as of December 31, you're considered to be married for the full year for tax purposes -- no matter what the wedding date. That means you'll file your taxes as married – either jointly or separately -- for 2017. You'll also be subject to the joint income limits for Roth contributions for the full year. If you’re married filing jointly and your combined adjusted gross income is less than $186,000, then you both can contribute the full $5,500 to a Roth for the year (or $6,500 if you're age 50 or older). Once your joint income reaches $186,000 to $196,000, then you both can make reduced contributions. You can't contribute to a Roth at all if your joint income is more than $196,000. See IRS Publication 590-A, Individual Retirement Arrangements, for a worksheet to calculate your modified adjusted gross income for the Roth limits.

The income limit is just $10,000 for married people filing separately if you lived with your spouse at any time during the year. If you earn too much to contribute to a Roth, you can both put money instead in nondeductible traditional IRAs for 2017 and then convert them to Roths. But you could be taxed on a portion of the rollover if you have any other money in traditional IRAs (the tax-free portion of the conversion is based on the ratio of your nondeductible contributions to the total balance in all of your traditional IRAs). See Converting Nondeductible IRA Contributions to a Roth for more information. Advertisement If you had already contributed to the Roth for the year and now your income disqualifies you, you would still have time to undo the contribution. Otherwise, you would have to pay a 6% penalty on excess contributions. You could take the contributions (and any earnings on them) out of the Roth before the tax-filing deadline, or you could have your IRA administrator switch your 2017 Roth contributions (plus all earnings on that money) into a traditional IRA. If you made contributions to the Roth in earlier years, the administrator should calculate how much of the earnings in the account should be attributed to the 2017 contribution. You can keep the money from previous years' contributions in the account. SEE ALSO: Why You Need a Roth IRA Got a question? Ask Kim at email@example.com.
