Individual Retirement Arrangements
Contributions to your individual retirement arrangements (IRAs) that are Traditional IRAs or Roth IRAs are generally limited to a certain annual dollar amount ($5,000 in 2011, or $6,000 if 50 or older) or your compensation that is includible in your gross income for the tax year. If you exclude income under the foreign earned income exclusion or the foreign housing exclusion, you must add back the excluded amounts in determining your compensation for purposes of the IRA limits. Likewise, for purposes of determining the IRA limits, do not reduce your compensation by any foreign housing deductions.
If you are covered by an employer retirement plan at work, your deduction for your contributions to your traditional IRAs are generally limited based on your modified adjusted gross income. This modified adjusted gross income is figured without taking into account the foreign earned income exclusion, the foreign housing exclusion, or the foreign housing deduction. In other words, you must add back any excluded amounts under the foreign earned income exclusion or foreign housing exclusion, and any deducted amounts under the foreign housing deductions, in determining the modified adjusted gross income limits for your traditional IRA contributions.
You report your income on a calendar-year basis and you qualified for the foreign earned income exclusion under the bona fide residence test for 75 days in 2011. In 2011, you excluded $19,089 of your $25,000 in foreign earned income (75/365 of the $92,900 maximum exclusion for 2011). In determining the maximum contribution to your IRA, you must add back the $19,089 in excluded foreign earned income to your compensation includible in your gross income or the modified adjusted gross income.
Other modifications are also required in determining the IRA limits. For more information on IRAs, see Publication 590, Individual Retirement Arrangements (IRAs), including Roth IRAs and Education IRAs.
