While you are not directly responsible, if you file your federal income tax return jointly with your husband and you both have a refund, the IRS will take it because your husband's name is on it. Also if the IRS starts collection efforts, anything with your husband's name on it is fair game.
You are not responsible for your husbands tax debt prior to marriage. However, you should not file a joint return, and you should keep your assets you bring into the marriage as your separate property until he clears this problem up. Otherwise, you may have assets subject to seizure in the future.

Generally speaking, assets and accounts held jointly with your husband may be accessible for properly filed tax liens or levies, and if you've filed jointly your refund owed is up for grabs as well. In either event, it is prudent to get your husband in tax compliance and avoid adverse impact on credit histories and cash flows. Your husband may be racking up penalties and interest making the situation far more costly. You may want to seek advice from a tax advisor to go over your specific facts and circumstances.
