The NFL blackmails cities into subsidizing stadiums for their billionaire owners.
They also insist on not paying any hotel taxes in the cities that host the Super Bowl.
If they don’t make a profit and don’t have any revenue over expenses, then they should not have to worry about being tax-exempt.
If they’re a non-profit I believe they can retain “earnings” for the next tax year without paying income taxes.
I'm no fan of the NFL. It's just kind of ridiculous to suggest that nobody gets any tax revenue from professional football teams.
