For the first time since the Reagan Administration, the U.S. Government has implemented a tremendous shift to the tax code creating major adjustments that have affected millions of taxpayers. To name a few changes, the child tax credit and threshold have increased, the standard deduction has doubled, and the state and local tax deduction has been limited for many taxpayers. Among the significant adjustments to the tax code includes a qualified business income (QBI) deduction for business owners of a flow-through entity. Flow-through entities include LLCs, sole-proprietorships, partnerships, s-corporations, and more. This article will describe the composition of the deduction and who was able to benefit the most from the deduction in 2018 and for years to come.
