Legal & Tax-Exempt Guidance for Athlete Foundations

Professional athletes often want to give back to their communities and support causes they care about. One effective way is by creating a foundation, a 501(c)(3) nonprofit entity.

But athlete foundations aren’t just charitable projects — they involve complex legal, tax, and governance requirements. Without proper setup, a foundation can face IRS penalties, lose tax-exempt status, or encounter public scrutiny.

Cullinane Law Group helps professional athletes and their teams build foundations that are legally compliant, mission-driven, and sustainable.

Why Athletes Start Foundations

Many professional athletes give back in different ways — volunteering, hosting fundraising events, or establishing foundations. As Steve Nash, retired eight-time NBA All-Star, says:

“I am a huge believer in giving back and helping out in the community and the world…I believe that the measure of a person’s life is the affect they have on others.”

A foundation allows athletes to amplify their impact, engage donors, and create a structured, long-term approach to philanthropy. All share the joy that comes from being a part of something bigger than themselves.

Types of Athlete Foundations

What is a Foundation?

Generally, a foundation is an organization that supports charitable activities for the common good. Foundations work to help other organizations, institutions, or individuals for scientific, educational, cultural, religious, or other charitable purposes.

Many philanthropic and charitable organizations are considered to be “foundations.” The name foundation itself can represent several types of organizations.

The IRS distinguishes between two entities:

  • Private foundations, which are often funded by an individual, family, or corporation.
  • Public charities, which may be nonprofit groups or community foundations that raise money from the general public.

Foundations can be established by individuals, families, corporations, or groups. Here, we focus on athletes because we have many clients — both current leaders in their sport and others retired from competition — who start foundations as a way to do more good in the world. Athletes often create them to formalize their giving. The main types include:

Private Foundations

Some athletes opt to organize “private foundations” that they endow and fund themselves. These entities may offer donors more control over their charitable giving.

Private foundations often invest their principal funding, then distribute the income from those investments for charitable purposes. Foundations often make financial grants to others. However, some private foundations also may operate programs. We help professional athletes and their advisors to set the foundation’s strategic plans.

  • Often funded primarily by the athlete or family

  • Often makes grants to other charities or operate programs

  • May offer specific tax advantages

We help athletes set up private foundations that maximize tax benefits and ensure proper investment and grant management.

Public Charities (Charitable Foundations)

Some athletes prefer to set up “charitable foundations” that have a public charity status because this entity may allow other individuals, corporations, and foundations to contribute to their foundation. These athletes may like to host special fundraising events (sports tournaments, galas, special events) to raise contributions for a cause that the athlete has pre-selected.

We work with the professional athlete to determine if this structure may offer tax deductibility options.

  • Often accept donations from the public, corporations, or other foundations

  • May host fundraising events like sports tournaments or galas

  • Offer donor tax-deductibility options

Professional athletes set up both types of foundations. We assist athletes and their professional advisors and agents in determining the best corporate and tax structure for their foundation to find success.

Challenges With Athlete Foundations

Professional athlete foundations are highly scrutinized. Issues can arise from:

  • Improper initial setup

  • Mismanagement or lack of oversight

  • Public and media scrutiny of spending

An ESPN “Outside the Lines” investigation of 115 charities founded by high-profile, top-earning professional athletes revealed that the investigated professional athlete’s foundations don’t measure up to what charity experts would say is an efficient, effective use of money.

In that investigation, reporters found that problems with misuse of funds, including how much money a foundation actually spent on charitable work as opposed to administrative expenses. The report also found problems with management, including whether there are enough board members overseeing the organization.

Our clients avoid these pitfalls. We provide guidance on structure, governance, and long-term management, ensuring foundations operate efficiently and ethically.
