Not recommended, but you can always just pull it out and pay taxes and penalties on it! This isn't a good plan, but sometimes it works to convince people to start.
If he is in the 15% tax bracket, for example.
Reduce pay check $100 to go into the account. Additional $25ish is put in based on the pre-tax nature of 401k deposits. Matched by $125. Account has $250. I'm assuming it is 100% immediately vested.
Withdraw it. Taxed at 25% +10% penalty= 35%. Get out $162.50!
So, if the concern is, "someday I might need it and it's locked away until I'm 60" that's not true. If, after vesting, he loses his job, runs out of emergency funds and pulls it out, he'll STILL have more than he put in. Again, not recommended as an actual plan for how to get your money out for early retirement, or what you SHOULD do. But, it might make someone scared that they are locking money away reconsider. Most people who are saving nothing don't need info on a Roth Pipeline or SEPP yet.
