Putting 2023 limits to work
If you had a workplace plan
Elective deferrals could total up to $22,500 ($30,000 at age 50+). Employer match sat on top of that until the combined §415(c) cap of $66,000.
If you also funded an IRA
You could still contribute up to $6,500 ($7,500 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 $330,000 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 $15,500 (+$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.
