The Tax Cuts and Jobs Act (TCJA) was signed into law on December 22, 2017. It was the most significant overhaul of the U.S. tax code in over three decades. The law introduced several provisions that are set to expire at the end of 2025. Their expiration will have notable impacts on both health and fitness facilities and fitness equipment or technology, and other suppliers. Fitness business owners should prepare for higher individual tax rates, the loss of the QBI deduction, reduced benefits from bonus depreciation, and potential changes in estate planning. Meanwhile, suppliers and manufacturers should anticipate similar challenges along with potential shifts in demand from their customer base. Strategic tax and financial planning will be essential for both sectors to navigate these upcoming changes effectively.
