The tax penalty (if applicable) will apply to just your husband, but will be assessed on your jointly-filed tax return.
Tax penalties apply to each individual uninsured adult or child in a household. If a person is uninsured for only part of the year, the penalty is prorated to cover only the uninsured months. No penalty is assessed for a "short gap," an uninsured period less than three months long. You are only allowed one short gap per year.
