(c) Application to spouse The provisions of this section shall apply to the spouse of any individual entitled to the benefits of subsection (a).

There shall be excluded from any amount assessed or collected pursuant to this paragraph the amount of interest, penalty, additional amount, and addition to the tax, if any, in respect of the period disregarded under subsection (a). In any case to which this paragraph relates, if the Secretary is required to give any notice to or make any demand upon any person, such requirement shall be deemed to be satisfied if the notice or demand is prepared and signed, in any case in which the address of such person last known to the Secretary is in an area for which United States post offices under instructions of the Postmaster General are not, by reason of the combatant activities, accepting mail for delivery at the time the notice or demand is signed. In such case the notice or demand shall be deemed to have been given or made upon the date it is signed.
