What is 401(k)?

A 401(k) is a retirement savings plan that an employer sets up for their employees. In a standard 401(k), employees can allocate a portion of their paycheck, pretax, to the retirement savings plan. The employee then pays taxes on their earnings much later (during retirement), when the money is withdrawn. This system allows employees to save for their future without having to rely on an employer offering a pension (another form of retirement savings plan that is being offered less and less often). 401(k) refers to to the specific section of the Internal Revenue Code that spells out this retirement savings plan.

Making the maximum annual contribution

The IRS has an annual contribution limit for anyone participating in a 401(k) plan. If you’re under 50, the maximum annual contribution amount for 2017 is $18,000 (excluding match) and if you’re 50 or older, the maximum annual contribution amount for 2017 is $24,000 (excluding match). Justworks automatically caps the limit, so you will not over contribute.
