Pierce Butler, Helvering v. Independent Life Insurance Company…
“ Where an insurance company owns and occupies the whole of a building, it receives no rents therefor and is not allowed to deduct the expenses chargeable to the building. Where part is used by the company and part let, the rents are required to be included in the gross, but expenses may not be deducted unless, if it be necessary, there is added to the rents received an amount to make the total sufficient, after deduction of expenses, to leave 4 per cent. ”
