Client is self-employed and has contributed to her SEP-IRA. Can she also make a nondeductible contribution to a traditional IRA?

A 45-year-old client is self employed and has contributed the 25 percent maximum to her SEP-IRA based on 2023 income. Can she also make a non-deductible contribution to a traditional IRA of $6,500 and then convert it to a Roth immediately?



  • First, the maximum permissible SEP contribution by a self-employed individual is 20% of net earnings, not 25%, because the SEP contribution effectively reduces the amount of net earnings on which the 25% maximum is applied.  Net earnings are net profit minus the deductible portion of self-employment taxes.  See IRS Pub 560.
  • A nondeductible traditional IRA contribution is permitted.  The sum of the traditional IRA contribution, the SEP contribution and the deductible portion of self-employment taxes is not permitted to exceed net profit from self-employment.
  • There are no restrictions on converting to Roth (except that any excess contributions to a traditional IRA (including a SEP IRA) are not eligible for conversion).

Thank you. 

Also, only a portion of the basis in nondeductible traditional IRA contributions will be allied to any particular distribution from the regular traditional IRA or the SEP IRA because the pro-rata calculation of the amount of the distribution that is nontaxable involves the balances in all of the individual’s traditional IRAs, which includes the SEP IRA.

If client is going to make a non SEP contribution (a personal IRA contribution) to the SEP account, the client should carefully flag it as such to the IRA custodian since SEP custodians are inclined to think that all contributions are SEP contributions. Such an error would result in an incorrect 5498. Client should then check the account to make sure the custodian recorded the contribution correctly and have them correct it if there was an error.
