Your IRA is subject to the Pennsylvania Inheritance Tax, which can prove to be a tax trap.
For example, if you leave $100,000 from your IRA to a friend, that gift is subject to the 15% Pennsylvania Inheritance Tax rate. To avoid interest and penalties on the Pennsylvania Inheritance Tax, within 9 months of your death your friend must pay the Commonwealth $15,000. If your friend does not have $15,000 of liquid assets, she may have to remove the $15,000 from the IRA. If she does, this will trigger her to recognize $15,000 of income. If she does not have the liquid assets to pay the income taxes due on the $15,000, she may have to remove the money from the IRA, which triggers even more income taxes.
