Form 15417-F: 403(b) Plan Matching and After-Tax Contributions Worksheet 11A

Form 15417-F (4-2023) is an IRS worksheet titled 403(b) Plan Nondiscrimination Requirements for Matching Contributions and Employee After-Tax Contributions. Its title also calls it Worksheet 11A, Determination of 403(b) Status. It reviews a named 403(b) plan question by question against section 401(m), with a Plan Reference column and Yes, No and N/A boxes on every item.

The instructions printed at the top of page 1 say "All items must be completed." They explain that a "Yes" answer generally indicates a favorable conclusion is warranted, while a "No" answer indicates a problem exists. If the employer has not requested a determination on an item and is not required to address it, the item is answered "N/A". The form notes that its technical principles may be changed by future regulations or guidelines.

The worksheet does not say who fills it out or where it goes, and no separate instructions are linked to it. You can fill it out free in your browser on this page and download the result without an account.

What's on Form 15417-F

Sections I to III: applicability, coverage and method

Whether the worksheet applies, whether coverage requirements are met, and how the plan meets the 401(m) nondiscrimination requirements: the 401(m)(11) safe harbor, the 401(m)(12) QACA safe harbor or the ACP test.

Section IV: safe harbor matching under 401(m)(11)

Items a to l, including the basic matching formula printed as a 100% match of the first 3% of compensation deferred, plus 50% match of the next 2%, and the 6% and 4% limits.

Section V: Qualified Automatic Contribution Arrangements

Completed only if the plan has QACA provisions. It includes the QACA basic matching formula printed as a 100% match of the first 1% of compensation deferred, plus 50% match of the next 5%.

Sections VI and VII: ACP test and corrections

Whether the plan includes the actual contribution percentage test, prior or current year testing, QNECs to pass the test, and how excess aggregate contributions are distributed or forfeited.

Sections VIII and IX: QNECs and definitions

Conditions for treating QNECs as matching contributions, and whether the plan defines highly compensated employee under section 414(q) and compensation for the ACP test.

The worksheet has nine sections over six pages. Each section ends with space to explain any "No" answers.
