2025 Irs Limit. Of note, the 2025 pretax limit that applies to elective deferrals to irc section 401(k), 403(b) and 457(b) plans increased from $23,000 to $23,500. The amount of salary deferrals you can contribute to retirement plans is your individual limit each calendar year no matter how many plans you're in.

This limit must be aggregated for these. The irs adjusts contribution limits and other tax provisions.
