Note: for the purposes of IRA MAGI qualification, a person filing as Married Filing Separately who did not live with his or her spouse during the tax year, is considered Single and will use the information on this page to determine eligibility.
For a Traditional IRA (Filing Status Single or Head of Household):
If you are not covered by a retirement plan at your job, there is no MAGI limitation on your deductible contributions.
If you are covered by a retirement plan at work, if your MAGI is $58,000 or less, there is also no limitation on your deductible contributions to a traditional IRA.
If you are covered by a retirement plan at your job and your MAGI is more than $58,000 but less than $68,000, you are entitled to a partial deduction, reduced by 50% for every dollar over the lower limit (or 60% if over age 50), and rounded up to the nearest $10. If the amount works out to less than $200, you are allowed to contribute at least $200.
If you are covered by a retirement plan at your job and your MAGI is more than $68,000, you are not entitled to deduct any of your traditional IRA contributions for tax year 2012. You are eligible to make non-deductible contributions, up the annual limit, and those contributions can benefit from the tax-free growth inherent in the IRA account.
For a Roth IRA (Filing Status Single or Head of Household):
If your MAGI is less than $110,000, you are eligible to contribute the entire amount to a Roth IRA.
If your MAGI is between $110,000 and $125,000, your contribution to a Roth IRA is reduced ratably by every dollar above the lower end of the range, rounded up to the nearest $10. If the amount works out to less than $200, you are allowed to contribute at least $200. If your MAGI is $125,000 or more, you cannot contribute to a Roth IRA.
