Tax-exempt employer may exclude qualifying 403(b) deferrals and cafeteria-plan health amounts from Section 4960 remuneration

Plain-English summary

Chief Counsel considered whether remuneration for the IRC § 4960 excise tax includes an employee’s elective deferrals to a § 403(b) annuity and salary reductions under a § 125 cafeteria plan for qualified health benefits. Section 4960 generally uses the definition of wages under § 3401(a), and those benefits are not expressly listed among that section’s statutory exceptions. IRS guidance nevertheless excludes qualifying amounts from income tax withholding to the extent they are excluded from gross income. The advice concludes that this withholding treatment also applies when calculating § 4960 remuneration. Accordingly, qualifying § 403(b) deferrals and § 125 health-benefit salary reductions are excluded from § 4960 remuneration to the extent they remain excluded from gross income and wages subject to withholding.

We received your request for assistance on determining whether the definition of
remuneration under §4960 includes an employee’s elective deferral amounts to
purchase a §403(b) annuity and an employee’s salary reduction amounts under a §125
cafeteria plan to purchase qualified health insurance benefits and other health benefits
that are excluded from gross income.

Section 4960(a)(1) imposes an excise tax on remuneration in excess of $1 million paid
by an applicable tax-exempt organization to any covered employee. Section 4960(c)(3)
generally defines remuneration as wages under §3401(a). Section 3401(a) provides that
“wages” for Federal income tax withholding purposes means all remuneration for
services performed by an employee for his employer, including the cash value of all
remuneration (including benefits) paid in any medium other than cash, with certain
specific exceptions. Section 3402(a) generally requires every employer making a
payment of wages to deduct and withhold upon these wages a tax determined in
accordance with prescribed tables or computational procedures.

Contributions to a §403(b) annuity and salary reduction payments to a §125 cafeteria
plan that pays for qualified employer-provided health insurance are not explicitly
excluded from §3401(a) wages under any of the exceptions found in §§3401(a)(1)-(23).
However, IRS guidance provides that these benefits are excluded from income tax
withholding under §3402 to the extent they are excludible from gross income. For
example, §403(b) contributions are excluded from an employee’s gross income and
thus not subject to income tax withholding to the extent annuity premiums and vested
annual additions do not exceed the limits under §402(g)(3) and §415, respectively. See,
Rev. Ruls. 65-209 and 70-453. Amounts in excess of those limits would be includible in
an employee’s gross income and subject to income tax withholding. Likewise, cafeteria
plan salary reductions to pay for health insurance premiums under §125 are excluded
from income tax withholding to the extent they are excluded from gross income under
§§105(b) or 106(a). Rev. Rul. 2002-3.
2

For the benefits at issue in this case, the exclusion from income tax withholding under
§§3401 and 3402 that is provided in IRS guidance should be treated as extending to the
§4960(c)(3) definition of remuneration. Accordingly, for purposes of calculating the
§4960 excise tax, §4960 remuneration should not be treated as including elective
deferral payments to purchase a §403(b) annuity or salary reduction amounts under a
§125 cafeteria plan to purchase qualified health insurance benefits and other health
benefits to the extent each of these benefits are excluded from gross income and wages
subject to income tax withholding.
