A A. There are certain restrictions when it comes to borrowing money from your Roth IRA. While you can't take out a loan from your Roth IRA like you can with other retirement accounts such as a 401(k), you may withdraw funds for short periods of time.

If you are younger than 59.5, you can still use your IRA funds to pay for college loans, but your withdrawals are likely to be subject to tax penalties.
