My ex-husband is filing back taxes for 04' & 05', when were still married. He had a small business, and I was a stay home mom at that time. We separated in 06', divorced in 09', and I remarried in 12'. I just received a collections notice from the IRS in my ex-husband's & my old married name, with his SSN, stating $14,000 needs to be paid within one week or assets can be seized! My ex said he's working with a tax professional, and I'm not liable for any of the money, that he's going to be paying it off. Why am I receiving a collections notice to my address, and can my current husband get stuck paying my ex-husband's tax debt?
