Proposed 10% Athletic Tax Targets Colleges Over Gender Participation Rules Starting in 2026

A new proposal aims to shift how the IRS interacts with college sports by hitting universities in the wallet if they don't follow specific gender participation rules. Starting after December 31, 2025, any 'applicable institution of higher education' that allows a male to participate in a female intercollegiate athletic event would be hit with a 10% excise tax. This isn't just 10% of the specific team’s budget—it’s 10% of the school’s total spending on all intercollegiate athletic programs for the entire year. For a major university with a $100 million athletic budget, we’re talking about a $10 million tax bill.

Defining the Boundaries of the Field

The bill uses very specific, biological language to draw its lines. Under Section 1, 'male' and 'female' are defined strictly by the reproductive systems an individual has, had, or would have (specifically referencing sperm for fertilization versus eggs). By anchoring these definitions to biology rather than gender identity, the bill creates a federal tax standard that may clash with existing diversity and inclusion policies at many universities. For a student-athlete who has transitioned or identifies outside of their biological sex at birth, this provision effectively creates a financial barrier to their participation in women’s sports.

The Cost of Competition

You might wonder if schools will just hike up fees to cover the IRS bill. The legislation anticipates this: it explicitly bans institutions from raising tuition or mandatory student fees to pay for this tax liability. The Secretary of Education is tasked with writing the rules to make sure schools don't just pass the buck to the student body. However, while tuition might stay flat, a 10% hit to a total athletic budget is significant. In the real world, this could mean a university chooses to cut smaller 'non-revenue' sports—like gymnastics, swimming, or track—to offset the tax costs or to avoid the risk of a violation altogether.

Practical Hurdles and Campus Impact

Implementing this would likely be a bureaucratic headache for school administrators and a point of tension for campus communities. Because the tax is triggered if a school allows participation for 'any portion' of the year, a single game or a single athlete could trigger the full 10% penalty. This creates a high-stakes environment for athletic directors who have to balance federal tax law against NCAA regulations and their own institutional values. For the average student or parent, the impact might not be a higher bill, but rather a change in which sports are offered or how their school navigates the increasingly complex intersection of federal law and campus life.
