For 2022, the maximum contribution to your 401(k) is $20,500. If you're over 50, there's an additional catch-up contribution allowed of $6,500, which means you could contribute up to $27,000 in total. Maximizing these contributions can significantly impact your tax planning since 401(k) contributions are made with pre-tax dollars, reducing your taxable income for the year. This can put you in a lower tax bracket while also helping you save more for retirement. It's a win-win if it fits into your financial strategy!
