The Alcohol and Tobacco Tax and Trade Bureau (TTB) is proposing amendments to the regulations for beer, wine, and distilled spirits to implement changes made to the Internal Revenue Code (IRC) by the Craft Beverage Modernization Act (CBMA) provisions of the Tax Cuts and Jobs Act of 2017, as amended and made permanent by the Taxpayer Certainty and Disaster Tax Relief Act of 2020.. This rulemaking addresses provisions applicable to domestic producers. TTB is proposing amendments to incorporate into the regulations the CBMA reduced tax rates and tax credits for domestic producers on distilled spirits, wine, and beer; statutory controlled group and single taxpayer limitations on these tax benefits; the ability to transfer beer in bond between unrelated breweries; the ability to transfer bottled distilled spirits in bond between distilled spirits plants in certain circumstances; and statutory changes to wine tax classes. The rulemaking will also remove outdated regulatory provisions that reflect prior law.
