Harry Blackmun,
Portland Golf Club v. Commissioner of Internal Revenue…
“ If each taxable activity of a social club is "deemed" to be a trade or business, then all of the expenses "directly connected" with those activities would presumably be deductible. Moreover, Portland Golf's interpretation ignores Congress' general intent to tax the income of social clubs according to the same principles applicable to other taxpayers. We therefore conclude that petitioner may offset losses incurred in sales to nonmembers against investment income only if its nonmember sales are motivated by an intent to profit. ”
