A key advantage of a 401(k) is its generous contribution limits, which allow workers under 50 to save up to $23,500 in 2025, not including any employer match. Those 50 and older can save even more, with a standard limit of $31,000. 

Thanks to a recent SECURE 2.0 Act update, workers aged 60 to 63 can contribute an additional $11,250 as a catch-up, bringing their total contribution limit to $34,750 for 2025. This higher limit, tied to inflation, could increase further in the future but reverts to $7,500 once participants turn 64.

Maximizing contributions is most beneficial for high earners looking to reduce taxable income while saving for retirement, but even smaller contributions can significantly impact long-term savings. 

Finsum: Advisors and investors should stay informed about future 401(k) changes to make the most of their retirement savings opportunities.
