He Had Five 401(k)s From Five Jobs. One Afternoon of Paperwork Put Them in One Account and the IRS Never Saw a Dollar, Because Every Check Was Made Out to the Custodian, Not to Him

A direct 401(k) rollover avoids all taxes when the check is payable to the new custodian FBO you, not to you personally.

If a rollover check is made out to you, the plan must withhold 20% immediately, and you have 60 days to replace it or owe taxes plus a 10% penalty.

Direct trustee-to-trustee transfers have no annual frequency limit, letting you consolidate multiple old 401(k)s in a single afternoon tax-free.

If you have an old 401(k) sitting at a former employer, the IRS has a rule buried in the tax code that decides whether your rollover is free or gets clipped for 20% before you ever touch it. The difference comes down to two words on a check: who it's payable to. Do a direct 401(k) rollover the right way, with the check made out to the new custodian, and every dollar moves. Do it the wrong way, with the check made out to you, and the plan is legally required to withhold 20% for federal taxes on the spot.
