Solo 401K Calculation Error
Currently I am using Turbotax Home and Business. In the business section > self-employed retirement. I have a solo 401K and I've entered the following:
Individual and Roth 401(k) plans
- Maximize Contribution to Individual 401(k) - YES
- Roth 401(k) elective deferrals = $23,500
Your Contributions
Enter the amounts that you contributed or will contribute to a Keogh, Traditional SEP, Roth SEP, Traditional SIMPLE or Roth SIMPLE Plan for 2025.
- I left this empty and clicked maximize to no.
- Prior years I have used an SEP IRA, but my understanding is since I have a solo 401K, I can do this as an employer contribution.
After I go through these screens it gives me
Retirement Contributions:
| Individual 401(k) | $0 |
| Roth 401(k) | $23,500 |
| Amount contributed | $23,500 |
| Maximum allowed to qualified plans | $36,162 |
| Amount to contribute by plan due date | $36,162 |
| Employer match | $0 |
The $36,162 value is correct in terms of the formula (Net Income - 1/2 SE)*20%. I am unsure here why for employer match is noted $0, but when looking at this intially, I assumed the $36,162 is what it is telling me I can contribute. However, after I go through the person section it gives me the below. Looking at this, it seems to be thinking the roth contribution is deductible, subtracting my contribution from the $36,162. In the end the deduction amount seems right, but unclear why Turbotax framing it seemingly incorrectly. I've tried to delete the Keogh, SEP, Simple Contribution worksheet, but it still gives me this same result.
Keogh, SEP, SIMPLE and /or 401(k) Maximum | $0 |
Amount to be Contributed by Plan Due Date | $12,662 |
Total retirement contributions | $0 |
Amount deductible | $36,162 |
