These tweaks could improve President Trump’s tax plan

House Speaker Paul Ryan (R-Wis.), center, and Rep. Kevin Brady (R-Texas), left, joined by other Republican legislators, during an unveiling of the tax reform plan, on Capitol Hill in Washington, Nov. 2, 2017. The business tax plan promoted by President Donald Trump, and its cousin released by the House, start with a good idea but descend into a mess. It can be fixed, writes economics professor N. Gregory Mankiw.

Let’s talk taxes. The business tax plan being promoted by President Donald Trump, and its close cousin released by House leadership last week, start with a good idea but then descend into an unworkable mess. Fortunately, the flaws can be fixed, if policymakers are willing to be bold.

The centerpiece of the Trump plan and the House bill is a cut in the tax rate on corporate income to 20 percent from 35 percent. This idea is eminently sensible.

Many economists believe the corporate tax is a bad way to fund the government. That is, compared with other taxes, it generates a lot of economic harm for each dollar of revenue it raises.

The case is especially compelling once we recognize that capital flows from country to country, seeking the highest after-tax return. Most nations have lower corporate tax rates than the United States, and the trend around the world has been to reduce corporate taxes. When a multinational company is deciding where to put its next capital project, the corporate tax is one factor affecting its decision.

Some may worry that a cut in corporate taxes would benefit only the firms’ wealthy owners. But that is not true, especially in the long run. Over time, lower corporate taxes would attract more investment in the corporate sector, increasing workers’ productivity and thus their wages.

There remains debate among economists about the size of the wage gains. But most agree that wages would increase and that the effect would grow over time. That is probably one of the reasons, in 2012, for President Barack Obama’s proposal to cut the corporate tax rate.

So far, so good. Yet a problem with the Trump plan starts to become apparent when one notices an inconvenient fact: Not all businesses are corporations.

Many businesses, especially smaller ones, are organized as pass-through entities. This means they do not pay taxes on their own. Instead, their income is attributed to their owners, who report this income on their personal tax returns. Such treatment applies to sole proprietorships, partnerships and subchapter S corporations.

Trump’s tax writers concluded, again quite sensibly, that it is not good policy to give a big tax break to conventional corporations without doing something similar for pass-through entities. Concerns about both equity and efficiency suggest trying to maintain a more level playing field between these two forms of business organization. So the Trump plan proposes a maximum tax rate of 25 percent for the pass-throughs.

Here is where the problem arises.

Once the pass-through rate is substantially below the tax rate for high-income wage earners, those wage earners have an incentive to reorganize themselves as pass-throughs.

Consider a physician employed by a hospital. She would have an incentive to quit and then sell her services back to the hospital as a freelance doctor. She performs the same services and receives the same payment. But now she is a sole proprietor rather than an employee, saving a substantial amount in taxes. (Disclosure: I am a freelancer for The New York Times, so my “writing business” might qualify, too.)

The Trump tax team says it will write regulations to preclude this kind of tax avoidance (and the House bill includes some rules to mitigate the problem). But the task will be difficult at best. At the very least, such regulations would complicate a tax system that is already too complex.

There is, however, an easy solution: Cut personal income taxes at the same time. As long as the top tax rate on personal income is close to the tax rate on pass-through entities, the incentive to reorganize to avoid taxes will be minimal.

This solution has two obvious problems of its own, but both of these can be solved.

The first problem is that the cuts I am suggesting would lose too much revenue. Yet the government can start raising revenue with other, better tax instruments. My first choice would be a tax on carbon emissions, which would both raise revenue and address the challenge of climate change. A close second would be a broad-based tax on consumption, such as the value-added taxes used in many other countries.

The second problem is that, depending on your political philosophy, my proposals might be seen as insufficiently redistributive. In other words, they wouldn’t do much, in themselves, to address wealth and income inequality. But redistribution can be added back in various ways.

One would be to expand the earned-income tax credit and the child tax credit, which benefit lower-income families. Another, more radical idea would be to use some of the revenue from the carbon tax and consumption tax to offer all Americans a monthly lump-sum dividend, along the lines of a universal basic income.

OK, OK, I know that I’ve come a long way from the Trump plan. And I know that, given the dysfunction in Washington, what I am proposing is a political nonstarter now.

But policymakers and voters should keep their eyes on what a better tax system might look like. Trump is right that the current system is in desperate need of repair and that sensible reform could simplify our lives, promote economic growth and benefit all Americans. But I fear that what he is offering, while attractive in some ways, is not bold enough to get the job done.
