Whether or not you or your spouse can make a Deductible IRA Contribution depends on your joint Modified Adjusted Gross Income (MAGI) and whether or not you and/or your spouse are "covered" by an Employer-Sponsored Retirement Plan (Retirement Plan Box Checked on Line 13 of your Form W2).
Note: You must have earned income to make IRA Contributions.
If neither of you are covered by an Employer-Sponsored Retirement Plan there are no limits on your MAGI for Deductible Traditional IRA Contributions.
If only you OR your spouse is covered by an Employer Sponsored Retirement Plan, the ability for the non-covered spouse to make a Deductible IRA Contribution phases out when your joint MAGI is between $189,000-$199,000.
If you are both covered by an Employer Sponsored Retirement Plan, the ability to make a Deductible Traditional IRA contribution phases out when your MAGI (Modified Adjusted Gross Income) is between $101,000 and $121,000.
When Married Filing Joint, your ability to make ROTH IRA Contributions, which are not tax deductible, phases out when your MAGI is between $189,000 and $199,000.
