A Roth SIMPLE IRA is not reported on Form 941. For employee Roth SIMPLE deferrals, the employer reports the amount on Form W-2, and IRS guidance says those contributions are included in wages and shown in box 12 with code S.

What goes where

  • Form 941: no separate Roth SIMPLE IRA line item is reported here.
  • Form W-2: employee Roth SIMPLE deferrals are included in taxable wages and reported with code S in box 12.
  • Form 1099-R: if employer contributions are treated as Roth under a SIMPLE IRA arrangement, those are reported on Form 1099-R as a taxable conversion/distribution.

Practical takeaway

If you’re trying to enter payroll, the Roth SIMPLE IRA amount generally affects wages and W-2 reporting , not Form 941 as a distinct retirement- plan field. In other words, the payroll tax return usually reflects the wages after proper treatment, while the Roth SIMPLE detail is tracked on the employee’s year-end forms.

Quick example

If an employee elects a Roth SIMPLE deferral, that amount is treated as after- tax for income tax purposes but still subject to payroll tax withholding rules, and it shows up on the W-2 rather than as a special 941 deduction.

TL;DR: Don’t look for a Roth SIMPLE IRA line on Form 941; use Form W-2 reporting, and in some cases Form 1099-R for employer Roth treatment.
