Generally speaking, if you have been filing returns separately (not a joint return) you should be fine. If you filed a joint return with your spouse then the IRS would certainly have a right to expect you to be responsible for taxes on those joint returns. Since he is filing separately, they should keep their inquiries on his tax liabilities to him. If they do try and collect from you, you need to get assistance and challenge the IRS request for this. Just don't ignore inquiries that the IRS makes, it won't help in the long run.
