## What Is a 401(k)?
A 401(k) is an employer-sponsored retirement savings plan that allows you to save and invest a portion of your paycheck before taxes are taken out. Named after section 401(k) of the Internal Revenue Code, these plans have become the primary retirement savings vehicle for millions of Americans.
The power of a 401(k) comes from three key features: tax advantages, employer matching contributions, and automatic payroll deductions. Together, these features make it one of the most effective ways to build long-term wealth and secure your financial future.
