Contribute to a Solo 401k, Roth IRA, and Traditional IRA for 2023

Contributions to Traditional IRAs and Roth IRAs Are Aggregated

Contributions to IRAs and Roth IRAs are aggregated. For 2023, the total contributions you make to all of your Roth IRAs and Traditional IRAs cannot exceed the following amounts:

  • $6,500 ($7,500 if you’re age 50 or older), or
  • if less, your taxable compensation for the year 

This means that for 2023 you cannot contribute the above limit to each type (i.e., traditional and Roth IRA); however, you can contribute some to each up to the  above combined limit. 

2023 Traditional IRA Contributions May NOT be Fully Tax Deductible

While the IRS rules allow for contributions to both Solo 401k plans and IRAs, if you are also participating in a solo 401k plan, you can still make the traditional IRA contributions but they may not be tax deductible. See the chart listed on the following IRS link for these  limits: https://www.irs.gov/retirement-plans/2023-ira-deduction-limits-effect-of-modified-agi-on-deduction-if-you-are-covered-by-a-retirement-plan-at-work

ROTH IRA CONTRIBUTIONS

While you can also contribute to a Roth IRA  and a solo 401k plan, not everybody qualifies for making a Roth IRA contribution if their modified AGI is over a certain limit. For these limits, please see the following chart: https://www.irs.gov/retirement-plans/amount-of-roth-ira-contributions-that-you-can-make-for-2023
