The Tax Cuts and Jobs Act (TCJA) created a new 20% deduction for qualified business income to reduce the tax burden on sole proprietors, the owners of S Corporations and partnerships and certain trusts and estates and their beneficiaries. On August 8, 2018, the Department of the Treasury (Treasury) issued proposed regulations interpreting the new provision. Taxpayers should take careful note of the new regulations as the pass-through deduction is effective for tax years beginning after December 31, 2017.
