US tax compliance rules are always changing. Some of these changes are helpful, but many are not. The most drastic changes in recent history occurred in 2017, with the Tax Cuts and Jobs Act (TCJA). These tax changes brought in the qualified business income deduction (QBID), which gives a 20 percent deduction against net business revenues for certain industries, which was hugely beneficial for self-employed people. However, this set of rules also imposed the $10,000 cap on the deduction for state and local taxes (which made it so much more difficult to itemize deductions). It also gave us the tax on global intangible low taxed income (GILTI), which hit owners of operating foreign corporations hard. The take-home here: Just because a tax benefit existed before, doesn’t mean it will remain available, but new laws can bring new benefits.
