What Happened to Corporate Tax Reform?

President Obama’s 2011 State of the Union Address contained ringing language on corporate tax reform:

Over the years, a parade of lobbyists has rigged the tax code to benefit particular companies and industries.  Those with accountants or lawyers to work the system can end up paying no taxes at all.  But all the rest are hit with one of the highest corporate tax rates in the world.  It makes no sense, and it has to change.

So tonight, I’m asking Democrats and Republicans to simplify the system.  Get rid of the loopholes.  Level the playing field.  And use the savings to lower the corporate tax rate for the first time in 25 years –- without adding to our deficit.  It can be done.

That was then. This year, instead, the White House is advocating a handful of minor fiddles that would raise corporate taxes on some while creating new loopholes for others. We won’t get the full details until the February budget message, but here is an outline of what to expect, courtesy of Reuters:

  • Eliminating a tax break for moving expenses when a U.S. company ships operations overseas. Replacing it with a tax credit of 20 percent for the expense of moving operations back to the United States. The White House says this is revenue neutral and would not add to the deficit.
  • Doubling the domestic production tax incentive for advanced manufacturers to 18 percent, while eliminating it for oil production, to urge manufacturers to create U.S. jobs.
  • Closing a tax loophole that allows U.S. companies to shelter profits overseas from intangible property, like royalties from a drug patent. The White House says this would raise $23 billion in revenue.
  • Proposing a new credit of $6 billion over three years for investments that help fund projects to improve economic activity in communities hit by major job losses or military base closures. To be done jointly with state economic development agencies.
  • Proposing an additional $5 billion in an advanced energy manufacturing tax credit the White House says would leverage nearly $20 billion in U.S. clean energy manufacturing.
  • Proposes extending for all of 2012 a provision to allow companies to deduct the full cost of investment in equipment, which the White House says yields $50 billion in tax relief over two years.

Not quite the same, is it? Let’s go back to first principles to see just what is wrong with the corporate tax and why it should be a priority area for tax reform.

The Uncertain Incidence of the Corporate Tax

Who bears the burden of the corporate income tax? Not corporations, which are not people, despite anything the Supreme Court might say. The economic burden of the corporate tax must somehow fall on real people—shareholders, other suppliers of capital, workers, customers, or someone else.

Economists have debated the incidence of the corporate tax for decades. A paper in the Virginia Tax Review, by Rosanne Altshuler, Benjamin H. Harris, and Eric Toder, provides a good summary.

Early work by Arnold Harberger, beginning in the 1960s, concluded that essentially all the burden fell on shareholders. That assumption has become the standard one used when presenting data on the way the overall burden of taxes is distributed among the population. However, Harberger’s analysis applied in full force only to a closed economy. In an open  economy, where not just goods and services, but also capital moves easily from one country to another, while labor is less mobile, things are likely to be different.

In today’s  open economy, capital flows to countries where corporate tax rates are low. As it does so, the amount of capital invested per worker falls in countries where tax rates are high. Less capital per worker means less productivity and consequently lower wages. In that way, the burden of corporate taxes is shifted to workers. How much of it is hard to tell. Maybe all, maybe 70 percent, maybe half. The shift may vary over time and from one industry to another. In any case, the hypothesis that shareholders bear the full burden of the corporate income tax is increasingly hard to defend.

How much difference does it make? A lot, because the standard assumption that corporate taxes fall entirely on shareholders seriously overstates the amount of taxes paid by high-income groups. For example, consider an estimate published by the Urban Institute-Brookings Tax Policy Center, which uses the standard assumption. The Tax Policy Center estimates that the top-earning 1 percent of taxpayers pay an average of 28 percent of their income in federal taxes, compared to 18.9 percent for the middle 20 percent. However, the 28 percent figure for the top 1 percent includes a corporate tax component of 7.9 percent. What happens if we assume that component falls on labor income, instead of on income to shareholders? Labor income constitutes 93 percent of all income for the middle 20 percent of taxpayers, but just 45 percent for the top 1 percent. It is reasonable to conclude, then, that shifting the assumed incidence of the corporate tax from shareholders to workers would reduce the gap in tax rates between the top 1 percent and the middle 20 percent by at least half. That would mean the U.S. tax system is quite a bit less progressive than the standard data indicate.

Too Many Loopholes

Principles of good tax policy call for a broad base, low rates, and a minimum of preferences, exclusions, and deductions. The U.S. corporate income tax, like the individual income tax, departs widely from the ideal.

Eric Toder of the Tax Policy Center estimates that eliminating corporate tax preferences could potentially save $506 billion over five years. The biggest preferences include deferral of foreign source income of U.S. multinationals, accelerated depreciation of machinery and equipment, a tax credit for low-income housing, and accelerated depreciation of other rental housing. The exact amounts saved are difficult to estimate because of the way different preferences interact and because of possible changes in behavior if tax rates were lower. Toder’s rough estimate is that if Congress closed all loopholes, it could lower the top corporate tax rate from 35 percent to 23 percent without loss of revenue.

Double Taxation of Corporate Profits

One of the most common complaints about the corporate tax is that it hits capital income twice, once when profits are earned by a corporation and again when they are distributed to shareholders. Congress has responded to the problem of double taxation with preferential personal income tax rates on capital gains and dividends, but as I explained in a post last week, that is the wrong approach.  Instead of taxing corporate profits at a high rate and then reducing the rate on capital gains and dividends, it would be better to lower the corporate rate and then tax capital gains and dividends as ordinary income. Making such a switch could reduce distortions to business practices without increasing the total tax burden on income from capital.

Decreasing Revenue

When Japan reduces its top corporate tax rate this year by 5 percent, as it says it will do, the United States will assume the honor of having the highest corporate tax rate in the world. Yet, despite the sky-high statutory rate and record-high profits, corporate taxes account for a steadily decreasing share of federal revenues. As the following chart shows, corporate taxes now bring in less than 9 percent of federal revenues, down from a post-World War II peak of over 30 percent. Many countries with lower  rates bring in more corporate tax revenue as a share of GDP.

In addition to leakages from loopholes, another reason the corporate tax doesn’t bring in much revenue is that most businesses do not pay it. About 7 million businesses file corporate tax returns, but three times that many are not subject to corporate taxes at all. Instead, they are individual proprietorships, partnerships, or subchapter-S corporations. Tax laws allow all of those to pass their profits through to their owners, who then pay taxes on them at individual rates.

What to do?

A case can be made for abolishing the corporate income tax altogether. The government could make up the lost revenue, now less than 10 percent of all federal taxes, in several ways, any of which would produce fewer distortions to business practices than the corporate tax in its current form. Taxing capital gains and dividends as ordinary income would be a good first step. Closing loopholes in individual income taxes would be another. Consumption taxes, like a value added tax or broad-based energy tax, are another possible element of broad tax reform. It would be possible to implement these measures in either in a revenue-neutral manner, or as part of a more comprehensive fiscal consolidation with a mix of spending cuts and revenue enhancements.

Wouldn’t eliminating the corporate tax be regressive? It would not have to be. The paper by Altschuler et al., cited above, estimates that shifting tax liability from the corporate to the individual level, by fully taxing capital gains, would, in itself, be moderately progressive. Remember also that the apparent progressivity of the corporate tax depends on the questionable assumption that shareholders bear its full burden. Finally, the effect on progressivity would depend on what kind of taxes were used to make up the revenue lost from eliminating the corporate tax. Taking all of these points together, we could eliminate the corporate tax in a way that made the system as a whole more progressive, made it less progressive, or left progressivity unchanged.

All discussions of the difficulty of taxing corporate income fairly and effectively comes back to the problem that corporations are not people. Instead, they are more like rats. Scientists say that rats, with their collapsible skeletons, can squeeze through a hole the size of a quarter. Corporations do much the same. With a stroke of a pen, they can morph into a limited partnership or a subchapter-S corporation. They can move their legal residence to an offshore tax haven quicker than you or I could load a U-Haul trailer to move across town. In fact, they don’t even have to move. They can stay right where they are and shift their profits to off-shore subsidiaries using transfer pricing, fees for use of intellectual property, or some other entirely legal gimmick. If corporations are incapable of bearing the economic burden of taxes and can easily evade even the formality of paying them, why tax them in the first place?

If abolishing the corporate tax altogether sounds too radical, the next best thing would be to broaden its base, lower its rates, and close its loopholes, and at the same time, increase individual tax rates on dividends and capital gains. Even modest reforms along those lines could get the U.S. corporate tax down from the highest rate in the world to the OECD average of around 25 percent. Just getting down to the OECD average would remove an important competitive disadvantage for U.S. businesses.

Would it be hard to get this done in an election year? Maybe it would, but that is no reason to take reform off the table altogether, let alone reverse course. Shouldn’t we expect something better in next month’s budget message? It can be done.

Increasing rates on dividends and capital gains? Sounds like disincentive to save and invest. I'd rather see a national sales tax levied than an increase in any income taxes.

Ed Dolan EdDolanFebruary 3rd, 2012 at 10:19 am

What the Altschuler paper cited above says is that you need to do is distinguish between an increase in taxes on income as a whole, and a revenue-neutral shift of those taxes from the corporate to the individual level. The paper argues that there are gains from the latter without any change in total taxes. However, I agree with you that sales/VAT/consumption taxes need consideration as part of the mix.

Indexing capital gains taxation to inflation would go part of the way towards alleviating the disincentive to save and invest, no?

Ed Dolan EdDolanFebruary 4th, 2012 at 9:45 am

Yes, it would go part way, but indexing capital gains by itself creates a different problem. It corrects for the distorting effect of inflation on capital gains taxation, but inflation also increases the real tax rate on bond interest and dividend income. The net result is that indexing capital gains in isolation increases the relative advantage of business strategies that favor generating maximum capital gains rather than interest or dividends. Such strategies are not always efficient.

There are two ways to deal with the problem. One would be to index the whole tax system, perhaps the best approach. Short of that, lowering the corporate tax and taxing capital gains as ordinary income would probably be better than just indexing capital gains in isolation. There is more on this in my Jan 23 post and in some of the links there.

ANY change in tax law risks creating another scheme to increase rents (see articles about Buffet would be effectively exempt from the Buffet rule – in effect taxing "the rich" to make the "superrich even more so" – not really progressive now, is it?)

And the greatest fear of many opposed to VATs and the like is that they could let government grow almost without bound. (You can say "VAT will replace income tax" – but show me 3 cases in real countries in all of history where that has happened?)

So cleaning up this part of the very complex tax/rent system probably requires a new kind of capital structure – something like a cross between a C corp and an LLC but perhaps with a sort of "mutual fund" flavor to it. The point being to remove the legal entity that is highly incentivized to lobby for bizarre rules.

And even that will require explicit limits on the size of government. You cannot starve the beast, you must cage it directly.

Ed Dolan EdDolanFebruary 4th, 2012 at 10:04 am

I agree that as long as we have taxes, we will have rent seeking. However, I don't see that as a reason not to advocate simplifications in the tax system, especially simplifications that lower high marginal rates and broaden the tax base. After all, high marginal rates are the main motivation for rent seeking in the first place. The flatter the tax system, the better.

I understand what you are getting at regarding the VAT. I am not really comfortable the argument, howeer. What you seem to be saying is that the more efficient the tax system is, the less resistance there would be to raising taxes, so the bigger government would get. I suppose you could argue that if we have a tax system that is full of bizarre loopholes and high marginal rates, the people who do pay taxes will fight harder against further tax increases. That seems like sort of giving up, though. I would rather continue to argue in favor both of a more efficient tax system AND a rational set of budget rules to deal with the spending side of the budget. For more on what such rules might look like, see my posts on Chile (July 24) and Sweden (July 31).

Sorry to be getting to this so long after you posted it. I've long thought that the optimal approach to the corporate income question is (a) abolosh the corporate income tax and (b) impute the income of the corporation to its shareholders *whether that income is distributed to them or not.* So a corporation with net income of $1 billion, with 100 million shares of stock outstanding, would have an income of $10 per share. That would be imputed to shareholders, so that, if you own 100,000 shares, you have $1 million in income.

Now, I know there are all sorts of implementation issues, and the existence of multiple classes of stock introduces even more complications. But imputing the income to the de jure owners of the corporation seems to me to be appropriate.

Ed Dolan EdDolanFebruary 7th, 2012 at 4:53 pm

The concept certainly makes sense. Like all other ways to tax capital income, it would have to be implemented in a way as free as possible from distortions caused by inflation. I think the ideas of shifting tax from corporate to individual level go part way in the direction you suggest.

Is there studies about the link between transfer price and corporate performance ?


Paul KatchingsMarch 17th, 2012 at 3:29 pm

There is a very serious business model (start up) underway that combines the tripartite solutions of double taxation, inflation, and 100% employment.

These are two great observations below…lets take these two observations farther.

“it would be better to lower the corporate rate and then tax capital gains and dividends as ordinary income” EdDolan

“abolosh the corporate income tax and (b) impute the income of the corporation to its shareholders *whether that income is distributed to them or not.” Donald A. Coffin

Taking the renaissance of capitalism out of the lab and placing it into a new vehicle called Limited Liability Public Company solves the tripartite questions in the only way and place that ubiquitous economics can be instantly solved…and this is in the private sector market place.

OK suppose you have zero corporate tax, then have a company registered in the USA which is mostly or wholly owned by foreigners. Let's say the company works in high tech and have relatively few workers who pay taxes, but high profits.

The company can benefit from American infrastructure and operate in the American marketplace, without paying almost any tax – any dividends from corporate profits would go abroad and be taxed (or not taxed) in the countries where the owners reside.

Does that make sense?

Ed Dolan EdDolanApril 30th, 2012 at 9:45 am

Yep, makes sense to me. Here's why

1. It would make greatest sense if we had reciprocity so that all countries operated symmetrically.

2. Fact that your foreign company operates here w/o paying taxes does not mean US gets no benefit from them. If they are profitable, they are doing something valuable. All their US counterparties, clients, customers, and suppliers make mutual gains on every transaction done with them. If they went home, every one of them would be worse off. That's how the market works.

Swedish holding companies are supposed to be attractive for corporate tax planning purposes; do you know in which exact way they are favorable?
