On Wednesday, Donald Trump’s administration revealed its massive, big-league plan to “reform” the tax code—or, more accurately, slash the corporate tax rate to 15 percent. Without any proposal to pay for such a massive cut, the White House proposal is unlikely to survive Congress in its current form. Still, the president has good reason to fight for it with every bone in his papaya-colored body: it’s likely to personally make him millions.

As Vox’s Dylan Matthews notes, Trump’s plan includes a provision cutting the top tax rate on so-called “pass-through” companies from 39.6 percent to 15 percent. And because the Trump Organization isn’t a C corporation but rather is “structured as a collection of pass-through enterprises,” most of Trump’s income is likely taxed through that system. Of course, we haven’t seen Trump’s tax returns, but if he is currently paying the 39.6 percent rate on his earnings, cutting that rate to 15 percent would potentially cut the president’s own tax liability in half. As it turns out, hosting foreign leaders at Mar-a-Lago (initiation fee $200,000) and running an ad for the club on the State Department’s Web site aren’t the only ways to use the presidency to personally enrich oneself.

The creation of a big, beautiful new loophole in the tax code isn’t the only change being pushed by the White House. The administration’s plan also calls for: reducing the income tax code to three brackets; repealing the 3.8 percent Obamacare tax on investment income; ending the Alternative Minimum Tax (which comprised the bulk of the taxes he paid in 2005, according to his leaked return from that year); and eliminating the estate tax.

Unfortunately, if Trump thought getting tax reform passed was going to be as easy as snapping his fingers and having K.F.C. delivered to the White House, he’s in for a giant, A.H.C.A.-size surprise. Per Politico:

The main problem, political analysts and tax experts say, is that Republicans are caught between two irreconcilable models for enacting major tax changes. The president’s plan...repeats his campaign call for slashing the top corporate rate from 35 percent to 15 percent and reducing and simplifying individual rates, while doing little or nothing to replace the trillions of dollars in lost revenue from such cuts beyond relying on rosy forecasts for faster growth.

House Speaker Paul Ryan, along with many of his Republican cohorts, are in favor of a border tax that analysts predict will result in more than $1 trillion in revenue over the next ten years, while the White House is said to be against a border tax claiming, in a tone of voice that would make Ronald Reagan proud, that the cut will pay for themselves.

“So far at least, the contours of this are starting to look a lot like what happened with Trump and Congress on health care,” former Mitt Romney campaign adviser Lanhee Chen told Politico. “On health care you had irreconcilable differences on the scope of government. And in the same way here, whether or not you pay for a tax cut is a fundamental difference Republicans have. And what we could see Wednesday is that there isn’t even as much middle ground on taxes as there was on health care.”
