What are T-Mobile’s 401(k) options?

T-Mobile supports three types of 401(k) contributions:

  • pre-tax

There are also three types of contributions:

  • match - the company match is currently pre-tax

What’s the maximum contribution?

Pre-Tax and Roth

According to the IRS, the 2024 maximum 401(k) contributions are:

  • $23,000 for the elective deferral

  • $7,500 for those age 50+

Someone who’s 50 years old could contribute $30,500 across the pre-tax and Roth 401(k) options.

After-Tax

Up to $69,000 can be contributed to all defined contribution plans.

If the employee contributes $23,000 and the employer matches $10,000, the employee could still contribute $36,000 to after-tax.

What are T-Mobile’s make-up or true-up contributions?

T-Mobile matches employee pre-tax and Roth contributions each paycheck.

An employee might reach the maximum early in the year. T-Mobile would have no contributions to match the rest of the year!

Without a make-up, employees who contribute more than 5% of their compensation would receive less than the 4% match.

Fortunately, T-Mobile makes them whole with a true-up contribution the following March.
