§4979A Tax on Certain Prohibited Allocations of Qualified Securities

Title 26 › Subtitle D — Miscellaneous Excise Taxes › CHAPTER 43 — QUALIFIED PENSION, ETC., PLANS › § 4979A

Last updated Sep 22, 2026|Official source

Summary

A 50% tax applies when employer stock or stock-like benefits are put into worker plans or owned in ways the tax code forbids. It covers four situations: forbidden allocations by an employee stock ownership plan (ESOP) or eligible worker-owned cooperative; an allocation tied to a special qualified-transfer rule; allocations that break the rules for employer securities in certain S‑corporation plans (or a defined “nonallocation year”); and when a disqualified person owns synthetic equity in a nonallocation year. A “prohibited allocation” means putting qualified stock from a 1042 sale into a plan or giving benefits in ways that break the 409(n) rules. The tax is paid by the employer or eligible worker-owned cooperative that made the required written statement for the first two kinds, and by the S corporation for the last two kinds. The tax equals 50% of the “amount involved”: for 409(p) violations it is the amount put into the person’s account; for synthetic equity it is the value of the shares behind the synthetic equity; for the first nonallocation year it is the total value of deemed-owned shares of all disqualified persons. The IRS has at least 3 years to assess the tax, measured from the later of the triggering allocation/ownership (or the first such allocation for the qualified-transfer case) or the date the Secretary is notified.
