Limit if Covered by Employer Plan
As discussed earlier, the deduction you can take for contributions made to your traditional IRA depends on whether you or your spouse was covered for any part of the year by an employer retirement plan. Your deduction is also affected by how much income you had and by your filing status. Your deduction may also be affected by social security benefits you received.
Reduced or no deduction. If either you or your spouse was covered by an employer retirement plan, you may be entitled to only a partial (reduced) deduction or no deduction at all, depending on your income and your filing status.
Your deduction begins to decrease (phase out) when your income rises above a certain amount and is eliminated altogether when it reaches a higher amount. These amounts vary depending on your filing status.
To determine if your deduction is subject to the phaseout, you must determine your modified adjusted gross income (AGI) and your filing status, as explained later under Deduction Phaseout . Once you have determined your modified AGI and your filing status, you can use Table 1-2 or Table 1-3 to determine if the phaseout applies.
Deduction Phaseout
The amount of any reduction in the limit on your IRA deduction (phaseout) depends on whether you or your spouse was covered by an employer retirement plan.
Covered by a retirement plan. If you are covered by an employer retirement plan and you did not receive any social security retirement benefits, your IRA deduction may be reduced or eliminated depending on your filing status and modified AGI, as shown in Table 1-2.
For 2009, if you are covered by a retirement plan at work, your IRA deduction will not be reduced (phased out) unless your modified AGI is:
More than $55,000 but less than $65,000 for a single individual (or head of household),
More than $89,000 but less than $109,000 for a married couple filing a joint return (or a qualifying widow(er)), or
Less than $10,000 for a married individual filing a separate return.
