A 401(k) plan is a tax-advantaged retirement savings plan provided by employers. It involves setting aside a portion of the employee’s monthly salary, which can be withdrawn during retirement. Introduced in the 1980s, 401(k) has been instrumental in helping people save money for their future. However, certain mistakes can prevent one from getting the most out of their 401(k) plan. Lapses here could also result in penalties. 1. Not contributing enough Some of the biggest mistakes people make with a 401(k) are not contributing enough or consistently and not increasing their contributions over time (to match their salary). As a result, they end up losing out on the compounding interests, settling for very little money. To steer clear of this mistake, one can set up the account to automatically draw contributions from the salary account. Today, one can also opt for automatic annual increases on a date of their choice or on the effective date of their salary raise to allocate more money for their retirement. 2. Missing out on employer match Many employers match the employee’s contribution. To build a bigger retirement fund, one should avoid missing out on these contributions.
