Turning 50 can change more than the number on the birthday cake. It can also open the door to larger 401(k) contributions, while a major SECURE 2.0 rule starts affecting certain workers in 2027. That matters because the catch-up contribution you have relied on for years may no longer get the same tax treatment. For some higher-paid employees, the catch-up portion must go into a Roth 401(k), assuming the workplace plan offers a Roth option.
So, age 50 is a useful point to stop treating retirement contributions as an automatic payroll setting. Your income, age, employer plan, and tax preferences can all start pulling the strategy in different directions.
