Ohio State season football ticket holders will no longer be able to deduct 80 percent of donations when purchased through a charitable organization.

Donald Trump and his gang of merry tax reformers delivered a blow to Ohio State football fans—or at least the ones with season tickets.

The Tax Cuts and Jobs Act—signed into law in December—eliminated a provision that previously allowed individuals to deduct 80 percent of charitable donations associated with the purchase of collegiate athletic tickets. At Ohio State, football fans are feeling the biggest impact. OSU reports the change affects about 7,500 donors, most of whom are members of the Buckeye Club, the athletic booster group that many join to secure season football tickets.

Most OSU season tickets (generally $681 per seat in 2018, slightly cheaper than last year's $695 price) are purchased through either the Buckeye Club or the President's Club, another donor group. If they make qualifying $3,000 contributions, President's Club members are given the chance to purchase home season football tickets, while members of the public need to make a minimum donation of $1,500 through the Buckeye Club.

Previous tax laws allowed ticket buyers to mitigate those costs. And though the practice was popular with universities, critics saw it as an unfair subsidy for the rich. A spokesman for U.S. Rep. Kevin Brady, chairman of the House Ways and Means Committee, described the deduction as “the epitome of a special interest loophole” to the Austin American-Statesman, while Bloomberg View columnist Joe Nocera cheered Republicans for going after the perk. “It is absurd to treat seat licenses like contributions to an engineering school, and its nice to see Congress finally acknowledging that,” he wrote.

Dan Caterinicchia, chief communications officer for the Ohio State Office of Advancement, said in an early March statement that OSU officials are contacting all affected Buckeye Club and President's Club members to explain the changes. Caterinicchia said that contributions above $1,500 remain tax deductible, and individuals who decline to purchase tickets are unaffected.
