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.
The IRS allows you to borrow money from your Roth (or traditional) IRA without consequences as long as you replace the funds within 60 days of receiving them. The action is considered as a rollover, in this case, from one account to the same account. You can only undertake this rollover once per calendar year per account.
