  2. Payments the taxpayer received under Temporary Assistance for Needy Families (TANF) or other public assistance programs to pay part of the cost of keeping up the home, cannot be counted as money paid by Taxpayer but must be included in the total cost of keeping up the home.

  3. Costs not to include. Do not include the cost of clothing, education, medical treatment, vacations, life insurance, or transportation. Also, do not include the rental value of a home if the Taxpayer owns the home; however, rental expenses for the home site, etc. can be included.
