President Donald Trump signed the Tax Cuts and Jobs Act (Public Law No: 115-97) on December 22, 2017, which makes major changes to the federal tax code. Given the budget constraints that lawmakers had in enacting tax reform, most of the tax changes for corporations are permanent and most of the tax changes for individuals expire and return to current law in 2026. BSCAI members should prepare now to determine what effects the changes will have on business operations.

The summary of the new law provided below by BSCAI’s government affairs staff is only a summary and should not be used as a substitute for professional accounting advice. BSCAI members are encouraged to speak with a tax advisor before making changes affecting their businesses.
