But if they are investing, isn’t that cutting into the owners profits?
that's probably a real complicated formula.
If someone owns 100% of teams, yes, they'd get 100% of whatever profits are generated. Of course, those profits would likely be taxed as dividends; and for high income people, interest and dividend income usually are taxed at the higher levels allowed by the IRS and states
however, if that owner has owned the team for longer than a year, then the proceeds from a partial sale would very likely be taxed as long-term capital gains. This nation, being in the pocket of the wealthy, sets the maximum federal tax rate on capital gains as 15%
so, for instance, somebody like Mark Cuban, who lives in Texas, which has no state income tax, could sell 10% of the Mavs...say for 400M, and put 340M in his pocket after taxes.
now, all that was true before the NBA decided players could buy into teams, so nothing is really changing as far as tax after sale. I'd wonder though about several things. Say Mark Cuban was looking at one of his players, like Doncic, approaching a new contract negotiation, and likely eligible for a max deal. Could Cuban offer that player a heavily discounted buy-in to the team in exchange for that player agreeing to a contract well below a max deal? Could it involve Cuban 'loaning' that player the buy-in amount with no-interest loan terms applied to future earnings?
What if the Mavs have a market value of 4 billion. But Cuban sets the partial sale value of the Mavs at 1 billion, then sells 5% of the team to that player for 50M; that when the actual market value of that 5% was 200M? The IRS is kind of geared to deal with sweetheart deals like that (
and many forms of those deals are actually legal as long as the feds get their cut). But how will the NBA, thru the CBA, deal with that? Will the difference between the discounted price and the market value count against the Mavs salary cap? I can't imagine how the NBA could calculate that.
I'm not a CPA or financial advisor. We have some of those people posting here so they could speak about this more informed than me. But it sure seems like the NBA could be opening up a giant can of worms with these rules. There's just too much fertile ground for shenanigans.
