An employee might have various benefits during their tenure, such as the ability to contribute to a 401(k) plan—a retirement savings plan that offers tax advantages to savers. Depending on the type of 401(k) plan one picks, the individual may gain benefits such as a reduced taxable income. However, without the proper understanding of a 401(k) plan, one could make multiple mistakes that could affect an individual’s long-term savings. Switching jobs before becoming vested in a 401(k) While an employer might match funds in one’s 401(k) account, the employee is not eligible to keep the money until they are vested. This process could be immediate or take years. For example, if the employee leaves the employer before matching the fund’s vest, the former will lose all of them. However, the employee would still be able to keep funds contributed from the paycheck. The individual should check the company’s policy before deciding to leave. Missing out on employer match Multiple employers provide matching funds if one contributes to a 401(k), which gives the employee additional incentive to save. For instance, the employer might offer 50% matching on an individual’s contributions up to 6%, meaning one would receive as much as 3% of the salary as an employer match.
