At a recent fundraiser, former President Trump, the presumptive Republican nominee for President, announced that, if elected again, he would extend his signature tax cuts to ultra-wealthy donors and major corporations. Worse yet, it was also previously reported that he actually plans to add more cuts that benefit corporations.

One particularly regressive provision in the 2017 bill is Section 199A, which delivered a 20% deduction of “qualified business income” of pass-through business owners. Pass-through businesses are all businesses in the U.S. that are not C-corporations -- including law firms, private equity companies, and hedge funds. The profits and losses for these businesses are “passed through” to the owners who pay taxes on their earnings via their personal income tax.

But as with most of the provisions of the Trump tax scam, Section 199A disproportionately benefits the wealthy. One study found that over 50% of the benefits of the pass-through deduction flow to the top 1% of earners alone. This provision is one of many that Congress must let expire come next year.

Republicans in both the House and Senate have already introduced legislation to extend some of the worst provisions of the Trump tax scam, including the pass-through deduction.

If we are going to address extreme and growing inequality in this country, Congress must start by letting the worst provisions of the 2017 Trump tax scam expire next year.
