“If my husband failed to file state tax returns prior to our marriage, am I now responsible to pay the past due taxes?”

Many states have what is known as an “innocent spouse” status, which provides protection for spouses who are married to someone who has not complied with the various tax requirements. That said, without evoking that status, it’s possible that your assets could be attached by your state’s tax authority. You should consult with a tax lawyer in your state, asap.
