I believe it's 15%, not 150%. Currently, individuals over 50 can make catch-up contributions of up to $7,500 in their 401(k) plans, as well as most 403(b) and 457(b) plans. Under SECURE 2.0, starting in 2025, individuals aged 60 to 63 will be able to make catch-up contributions of $10,000 or 50% more than the regular catch-up amount in 2025 — whichever is greater. The increased amounts will also be indexed for inflation after 2025.
