WASHINGTON -- Of all the follies of 2017, the most tawdry may be the GOP's headlong rush to pass a tax bill that even its proponents don't understand. What's especially sad is that otherwise sensible Republicans seem to be capitulating to the tax-cut frenzy.
Political desperation is the mother of this legislation. Despite Republican control of both houses of Congress, the Trump administration has failed in its first year to enact legislation that deals with major problems, such as health care and immigration. So at year end, we have the spectacle of Trump & Co. bellowing a populist message about lower taxes, even as special-interest lobbyists drive the legislation toward a chaotic conference and final passage.
The tax bill is a Rubik's Cube of potential problems, but the difficulties begin with the fact that it has been pushed through Congress in two months without hearings or careful analysis. The provisions were crafted in secret and passed on party-line votes, without a chance for assessment or analysis.
This haste guarantees confusion later. Without a clear legislative history, tax lawyers at the Internal Revenue Service won't have adequate guidance when they try to write regulations implementing the law. Courts won't have a record of congressional intent, other than press conferences, tweets and hurried floor and committee statements.
The centerpiece of the legislation is a big cut in corporate taxes, down from 35 percent to roughly 20 percent. The theory is that this will encourage companies to invest in job-creating plants and equipment. But there's little evidence to support this assumption, and lots to challenge it. Companies may instead use the windfall to buy back their own stock, boosting stock prices and inflating executives' personal compensation, as Steve Clifford explains in his recent book, "The CEO Pay Machine."
The premise is that by stimulating growth, the tax cuts will pay for themselves. But there's no good evidence for this claim, either. Congress' bookkeeper, the Joint Committee on Taxation, predicts that over 10 years, the tax law would balloon the deficit by roughly $1 trillion, even assuming that it stimulates new growth. An even more pessimistic estimate was issued Tuesday by the Wharton School, which President Trump is always bragging about having attended.
The Treasury Department on Monday offered a one-page rebuttal asserting that Trump administration policies, including the tax cuts, would grow the economy by 2.9 percent over the next 10 years (much higher than most other forecasters have projected) and reduce the deficit by $300 billion. Take a bow, Rosy Scenario.
The capricious effects of the bill are becoming clearer as Congress races to marry the House and Senate versions. Tech companies are howling that they will lose the benefits of research credits if they have to pay an alternative minimum tax (as in the Senate version). Homeowners will be hurt by new limits on the deductibility of interest payments; but landlords, meanwhile, will benefit from new breaks for pass-through companies, argues a Bloomberg analysis. How is that fair?
An analysis by 13 law professors last week warned that the legislation will produce "tax games, roadblocks and glitches" as companies, individuals and state and local governments try to manipulate the new system. "Congress should immediately reconsider its approach," the tax lawyers pleaded.

One of the trickiest games ahead was explained in a research report published Tuesday by Goldman Sachs. The tax bill implicitly punishes high-tax "blue states" by limiting the deductibility of state and local taxes. But Goldman analyst Alec Phillips noted that affected states might "change their own tax systems to reflect the new federal system," by reducing personal income taxes and adding more state-level value-added taxes or property taxes. That could reduce federal revenue.
One more hidden danger: Existing tax law is mildly counter-cyclical (in that tax receipts increase when times are good and decline when they're bad). But the Goldman analyst notes that provisions in the new law "look likely to move the tax code in a more procyclical direction." That's dumb economics.
Robert Crandall, the former CEO of American Airlines and one of the smartest business executives around, described the tax bill last week as "particularly stupid because there is a broad consensus of bipartisan agencies and economists who agree it cannot increase growth by anywhere near enough to offset the revenue losses." He's right.
Responsible Republicans seem to have adopted a fatalistic view that it's too late to clean up this mess. They're wrong. Voters will remember who tried to slow the rush toward passage of this ill-considered legislation and who jumped onto the bandwagon.
