The 401(k) allows employees to contribute a portion of their salary to a tax-deferred investment account directly from their pay check.
Employers may also choose to make contributions to the account on behalf of the employee. The money in the account can then be invested in a variety of options, such as mutual funds, stocks, and bonds.
The money in a 401(k) plan are not taxed until they are withdrawn, at which point they are subject to income tax.
Additionally, many employers offer matching contributions, which can help employees save for retirement more quickly.
However, a 401k may or may not be the best investment for you.
