While Trump has long refused to abide by the customs and traditions that dictate tax disclosure by presidents and presidential candidates, we know enough about his taxes to see that his new plan, although sorely lacking in detail, will serve his personal interest above all. (No, he didn’t put “America first.”) Although tax policy is often complicated and numbingly dull, the changes that Trump is seeking to benefit himself are really quite simple. The plan’s biggest “reform” is to slash the corporate tax rate from 35 percent to 15 percent — including the rate on so-called pass-through companies. Unsurprisingly, Trump owns more than 500 such firms, which allow his income to be taxed at the lower business rates rather than payroll rates. It also cuts the personal income tax rate on the highest earners, such as Trump, and the 3.8 percent Obamacare tax on unearned income. The reforms eliminate the alternative minimum tax, which required Trump to pay $31 million in 2005, according to a tax return that leaked last year. And the plan establishes a “territorial” tax system leaving all the profits earned by The Trump Organization in foreign countries. He aims to take care of his children, too, if not yours or America’s — so his plan also eliminates the estate tax entirely, allowing his billions to be inherited absolutely tax-free by Ivanka, Don Jr., Eric, Barron and perhaps Tiffany.
