The amount of IRA contributions you are able to deduct has a limit determined by your income and may be limited or phased out completely, depending on how much income is reported. However, you can still contribute to your IRA using non-deductible contributions. Although your contribution will not aid in reducing your taxable income, the earnings will be tax deferred until you withdraw the funds.
The current rates for each filing status may be found in the Form 8606 Instructions found on the IRS website.
Any nondeductible IRA contributions will be calculated by the program and pulled to Line 1 of Form 8606 when you report your traditional IRA contributions under the Federal Section > Deductions >Select my forms > Adjustments > IRA Deduction.
