1. (1) A household shall include the taxpayer, or in the case of a joint return, taxpayers, and all tax dependents.

   1. (A) In the case of a married couple living together, each spouse shall be included in the household of the other spouse regardless of whether they expect to file jointly or whether one (1) spouse is expected to be declared as a tax dependent of the other spouse.
   2. (B) In determining the household size of a pregnant woman, the division shall count the pregnant woman plus the number of unborn children she is expecting to deliver.
