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. The withdrawal of these funds are tax-free, penalty-free and interest-free, according to Bible Money Matters.
Instructions. Borrow money from your Roth IRA up to the amount you contributed this tax year. There is only one way to borrow from a Roth IRA and be able to put the money back into the investment. If you invested $3,000 into your Roth IRA in the tax year of 2008, you could take this $3,000 back out during 2008.
