No. You will not inherit his debt. However, if you file jointly with him after you are married, you will lose any refund that you would have otherwise gotten. The reason being, the IRS will confiscate the refund if there is a balance due from previous years for your husband. If your future husband owes a substantial amount of back taxes, you may want to consider filing "Married/separate."
