While your entire investment strategy should not revolve around tax advantages, people who pay attention to these benefits can save themselves a significant amount of money.
You can choose to keep the money in their 401(k) plan, transfer it to a new employer’s plan, or roll it into a Traditional IRA without paying penalties or fees.
The main difference between a traditional 401(k) and a Roth 401(k) is that a Roth 401(k) is tax-deferred rather than giving you a benefit the year you contribute.
