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 that page to determine eligibility.
For a Traditional IRA (Filing Status Married Filing Separately):
If you are not covered by a retirement plan at your job and your spouse is not covered by a retirement plan, there is no MAGI limitation on your deductible contributions.
If you are covered by a retirement plan at your job and your MAGI is less than $10,000, you are entitled to a partial deduction, reduced by 55% for every dollar (or 65% 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 $10,000, you are not entitled to deduct any of your traditional IRA contributions for tax year 2015. 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.
If you are not covered by a retirement plan but your spouse is, and your MAGI is less than $10,000, you are entitled to a partial deduction, reduced by 55% for every dollar over the lower limit (or 65% 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.
Finally, if you are not covered by a retirement plan but your spouse is, and your MAGI is greater than $10,000, you are not entitled to deduct any of your traditional IRA contributions for tax year 2015. 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 of Married Filing Separately):
If your MAGI is less than $10,000, your contribution to a Roth IRA is reduced ratably by every dollar, 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 $10,000 or more, you can not contribute to a Roth IRA.
