My grandsons paternal grandmother hasnt filed taxes since 2009 or 2010 because she received over 9,000 refund that year but did something fraudulent because the IRS says she has to repay that amount. In 2014 she cashed her retirement out early and received 61,000 dollars and did not file a return, pay any taxes or penalty amounts for the money she received and now the IRS is looking for her. She currently stays with me because she lost her home. Will I bebin trouble if I don't tell the IRS where she is? Do I have to worry about her being arrested when they find out wherebshe resides?
