A luxury tax in professional sports is a surcharge put on the aggregate payroll of a team to the extent to which it exceeds a predetermined guideline level set by the league. The ostensible purpose of this "tax" is to prevent teams in major markets with high incomes from signing almost all of the more talented players and hence destroying the competitive balance necessary for a sport to maintain fan interest. The money derived from the "tax" is then divided among the teams that play in the smaller markets, presumably to allow them to have more revenue to devote toward the contracts of high-quality players.
