Most US employees believe you can only contribute $20,500 per year in 2022 ($27K if over age 50) as an employee to “max out” your company retirement plan/401(k).
However, if you have the after-tax contribution option through your company, you can actually put up to $61,000 ($67,500 if over age 50) per year combined with your $20,500 employee contribution + your employer match + the after-tax contributions.
For example, if you save $20,500 to your 401(k) via traditional employee contribution and you receive $5,500 in a company match, you can still put another $35,000 of after-tax contributions (more if over age 50.)
