Taxpayers with higher 1040 taxable incomes who are self-employed but are not “specified service businesses” may find it beneficial to structure new businesses, or restructure an existing business, as an S corporation to avoid taxable income limitations that apply to the new 20% Sec. 199A pass-through deduction.
To make up for the tax reform’s reduction of the C corporation tax rate to 21%, from which other forms of business activities do not benefit, Congress created a new deduction and code section: 199A. The 199A deduction is for taxpayers with other business activities – such as sole proprietorships, rentals, partnerships and S corporations – since, unlike C corporations, which are directly taxed on their profits, the income from the other business activities flows through to the owner’s tax return and is taxed at the individual level, i.e., at the individual’s tax rate, which can be as high as 37%.
This new Sec. 199A deduction is 20% of the pass-through income from these business activities. But not every owner of these flow-through businesses will benefit from this deduction because, as in all things tax, there are limitations.
