Do you know how 2023’s weekends and holidays adjust due dates?

[Peter Gulia]

For services about an individual-account (defined-contribution) retirement plan, here’s a few key due dates, and whether each is (or isn’t) adjusted under the Treasury department’s rule about a return or payment due on a Saturday, Sunday, or legal holiday. For Form 5500 reports, the Labor department follows Treasury’s rule.

January 15, a Sunday, is adjusted to Tuesday, January 17.

March 15, a Wednesday, is not adjusted.

April 15, a Saturday, is adjusted to Tuesday, April 18.

If a Federal tax return is due on a Statewide legal holiday of the State in which the filer resides or a holiday of the District of Columbia, the return is timely if filed by the next day that is not a Saturday, Sunday, or legal holiday. 26 C.F.R. § 301.7503-1. In 2023, the District of Columbia’s Emancipation Day is observed on Monday, April 17. D.C. Code § 28-2701.

Internal Revenue Code of 1986 § 7503 might provide no adjustment for something a retirement plan provides—for example, a corrective distribution—rather than an act the Internal Revenue Code commands.

June 29 (180 days after 2022 ended), a Thursday, is not adjusted.

July 29 (210 days after 2022 ended), although a Saturday, is not adjusted.

See 29 C.F.R. § 2520.104b-3 (Summary of material modifications to the plan and changes in the information required to be included in the summary plan description).

July 31, a Monday, is not adjusted.

September 15, a Friday, is not adjusted.

October 15, a Sunday, is adjusted to Monday, October 16.
