Here's what this means: If you participate in an employer's retirement plan, such as a 401(k), and your adjusted gross income (AGI) is equal to or less than the number in the first column for your tax filing status, you are able to make and deduct a traditional IRA contribution up to the maximum of $7,000 (or $8,000 if you're 50 or older) in 2025 and $7,500 (or $8,600 if you're 50 or older) in 2026.
If your AGI is between the numbers in both columns, you are eligible to deduct a partial traditional IRA contribution. Finally, if your AGI is as much as or more than the phaseout limit in the last column, you are ineligible for the traditional IRA deduction.
