I switched to S-corp taxation. Can my SEP use business profit like before?
An S-corporation SEP calculation generally uses eligible employee compensation, not shareholder distributions or a sole proprietor net-profit formula.

An S-corporation SEP calculation generally uses eligible employee compensation, not shareholder distributions or a sole proprietor net-profit formula. Confirm the election year, owner payroll and plan terms before calculating the contribution.
A business-owner scenario
A sole proprietor elected S-corporation treatment and continued contributing a percentage of net business profit to a SEP. The first corporate year now contains owner wages and distributions. The administrator needs the effective election date and payroll information before validating the amount.
Illustrative scenario, not a client result.
Work through the transaction
- Confirm the election's effective year.
- Identify eligible compensation under the SEP.
- Reconcile employee participation and amounts already contributed.
The mistake that changes the result
Shareholder distributions are not a substitute for the compensation measure used in the corporate retirement calculation.
Records that resolve the question
- Election acceptance.
- Payroll.
- SEP agreement.
- Deposit records.
The decision to document
Request a recalculated contribution schedule and review any excess or missing employee amount with the provider. Align next year's payroll and funding forecasts so the old sole-proprietor method is not repeated.
Which fact changes the answer?
If the election began partway through the relevant history or earlier returns used a different treatment, preserve those periods separately. The provider should calculate from confirmed compensation and status rather than infer them from a current business bank statement.
