• Traditional IRA contribution limit: To calculate the traditional IRA contribution limits, the calculator first determines the individual’s age, as those who are 50 years old or older can make additional catch-up contributions. Next, it assesses the individual’s income level and filing status to apply the appropriate income phase-out ranges, which can affect the deductible amount of the IRA contributions. The calculator then checks if the individual or their spouse is covered by a retirement plan at work, as this also impacts the deductibility of contributions. Finally, the calculator uses this information to determine the maximum contribution amount that can be deducted for the tax year.

• Roth IRA contribution limit: To calculate Roth IRA contribution limits, the calculator first assesses the individual’s filing status and modified adjusted gross income to determine eligibility, as Roth IRAs have income limits. Next, it checks the individual’s age to see if they qualify for catch-up contributions, which are additional contributions allowed for those 50 years old or older. The calculator then uses this information to determine the maximum contribution amount for the year, keeping in mind that contributions to a Roth IRA are made with after-tax dollars and are not tax-deductible.

• SEP IRA contribution limit: To calculate the SEP IRA contribution limit, the calculator adjusts the net profit by reducing it by the deductible portion of the self-employment (SE) tax and the amount of the individual’s own retirement plan contribution. This adjusted net profit is then used to determine the plan compensation, which is necessary for calculating the SEP IRA contribution.
