A charity under the management of former first daughter Ashley Biden has been hit with a complaint alleging the organization has been dodging its tax obligations for years.

The daughter of the former president failed to ensure that $500,000 in donations were properly disclosed to the Internal Revenue Service in a timely manner, according to a letter released Monday by a conservative watchdog group.

While Joe Biden was still in office, Ashley launched a walk-in trauma recovery center in Philadelphia in 2023 aimed at supporting women facing mental health challenges. The center, named the Women’s Wellness Spa(ce), received $500,000 in initial funding from several high-profile philanthropists, including the foundation founded by Prince Harry and Meghan Markle, as well as the Silicon Valley Community Foundation.

According to IRS Form 990 filings, each nonprofit reported contributing $250,000 to Ashley Biden’s initiative that year. However, the Women’s Wellness Spa(ce) reported significantly less in its own filings, stating it received just $170,296 in total contributions and did not list any single donation exceeding $5,000. Ashley Biden signed the documents as president, under penalty of perjury.

Paul Kamenar, an attorney with the National Legal and Policy Center—the group that filed the complaint—said they are seeking to determine whether Ashley Biden’s organization received any additional undisclosed income. He also called on the IRS to consider potential sanctions.

“Ashley Biden’s failure to disclose to the IRS receiving $500,000 in grants in 2023 raises the question of what other contributions is she hiding,” Kamenar told the Washington Free Beacon.

Greg Mangasarian, an accountant with Women’s Wellness Spa(ce), explained that most of the $500,000 in donations would not be distributed until 2024 and that this would be accurately reflected in the organization’s latest tax filings. “The Women’s Wellness Space received $150,000 in 2023 and will report the balance in 2024,” Mangasarian said.

Despite the explanation, Mangasarian noted that his office follows the accrual method of accounting, which requires donations to be recorded and reported as they are received—not just during tax season.

Kamenar’s watchdog group contends that if the IRS determines Ashley Biden’s charity misreported its 2023 revenue, she could ultimately face financial penalties.
