Putting 2024 limits to work

If you had a workplace plan

Elective deferrals could total up to $23,000 ($30,500 at age 50+). Employer match sat on top of that until the combined §415(c) cap of $69,000.

If you also funded an IRA

You could still contribute up to $7,000 ($8,000 at 50+) across Traditional and Roth IRAs combined—separate from the 401(k) deferral limit—subject to earned income and phaseout rules for that year.

Compensation cap reminder

Plans generally could not count compensation above $345,000 when computing contributions under §401(a)(17). That matters for highly paid employees and owner plans even when the elective-deferral limit is the headline number.

SIMPLE vs regular 401(k)

SIMPLE elective room was $16,000 (+$3,500 at 50+). If your employer offered a SIMPLE instead of a regular 401(k), use those lower caps—not the §402(g) figure above.
