The IRS and Treasury issued proposed regulations providing interim guidance on the new Section 199A 20% deduction on Qualified Business Income (QBI) introduced under the Tax Cuts and Jobs Act. The law contains a series of complex provisions, definitions and computations, many of which are addressed by the Service. The preamble to the regulations provides that taxpayers can rely on this guidance until such time that final regulations are issued.

This new provision of the Internal Revenue Code allows owners of sole proprietorships, S corporations, LLCs, or partnerships a deduction of up to 20% of the income earned by the business.
