What happens if I withdraw my 401K to pay the tuition of my university?

If you are under the age of 59 1/2  there will be a 10% early distribution penalty assessed on your tax return when reporting the Form 1099-R you recieved.

Withdrawing from your 401(k) to pay university tuition is taxable income, and if you’re under age 59½, it’s usually also subject to a 10% early withdrawal penalty.

Unlike IRAs, 401(k) plans do NOT have a tuition exception to the 10% penalty. The higher education exception applies to IRAs only, not 401(k)s.

Additional tax on early distributions from retirement plans other than IRAs

[Hal_Al]

You are allowed to withdraw  money from your Traditional IRA (not Roth) with out the 10% penalty. Tax (but not the penalty) is still due.

The penalty waiver does not apply to 401k accounts.  So, under age 59.5, you pay both tax and penalty.
