Investor alert: Trump’s tax cuts are looking iffy

A lot is riding on the tax cuts President Donald Trump has promised by the end of 2017. Stock markets have soared on the expectation of lower corporate taxes and higher after-tax earnings. Consumer confidence is up too, as ordinary Americans anticipate the middle-class tax relief Trump crowed about in his recent address to Congress.

But the path to tax cuts on Capitol Hill is narrower and riskier than upbeat investors, who have been gobbling up stocks, seem to believe. Changes in tax law always create new classes of winners and losers—and every group poised to lose under Trump’s tax reform is rapidly mounting opposition. “The odds of tax reform are always less than 50-50, and that’s true this year,” Republican economist Douglas Holtz-Eakin said at a recent conference on tax reform in Washington, DC. “We need these forces to get lined up in the White House, and that hasn’t happened yet.”

The S&P 500 stock index has risen about 11% since Trump got elected in November. It’s impossible to know exactly how much of that gain is due to tax-cut expectations. But it’s a fair bet that investors think the odds of steep tax cuts occurring this year are a lot higher than 50-50. So if Holtz-Eakin is right, overly buoyant markets are mispricing the likelihood of tax cuts, with some kind of correction due.

Trump has not yet submitted his tax plan to Congress. House Republicans, however, unveiled a tax plan last summer that is now emerging as the basis for legislation this year. And they don’t plan on just moving the furniture around. Instead, they want to boldly restructure the way businesses and consumers pay taxes. They say their plan will reduce tax dodging, give US corporations an advantage over foreign competition and substantially boost economic growth.

The same boldness could also doom the legislation, however—and this may be the part of tax reform that ebullient investors aren’t paying enough attention to. The House plan relies on a novel “border-adjustment tax,” or BAT, to revamp the way corporations pay taxes. The BAT often gets conflated with Trump’s call for “border taxes,” but these are actually two different things.

Trump’s border taxes would basically be punitive tariffs on select products or classes of products, put into place one by one to punish trading partners the Trump administration feels aren’t dealing fairly with the United States. Most economists think this kind of protectionism does more harm than good, and Trump himself may only be threatening such tariffs as a negotiation ploy.

The BAT is a much broader plan that would affect virtually all imports and exports—and fundamentally change the US tax code. The basic idea is to tax products where they’re purchased or consumed, which is how a value-added tax works in the more than 160 nations that have one. The US does not have a value-added tax, which opponents of the idea often characterize as a national sales tax.
