Summary
Tax experts — including one who supports Romney’s plan — say the Republican presidential candidate’s promise to cut individual income tax rates without either favoring the wealthy or losing revenue isn’t mathematically possible.

That’s the conclusion of the Tax Policy Center in a report the Romney campaign attacked as “biased” (although the campaign previously praised the TPC as “objective,” when it issued a report critical of a rival’s tax plan).

And it’s also the conclusion of an expert from the pro-business Tax Foundation, who states that the Tax Policy Center analysis “correctly identified the Romney plan as a tax cut, at least in static terms, that accrues mainly to high-income earners.”

Romney has proposed very specific tax cuts. He would make the Bush-era income tax cuts and capital gains tax cuts permanent, then cut all income tax rates by an additional 20 percent across the board, repeal the Alternative Minimum Tax (which hits primarily upper-income taxpayers), and permanently repeal the estate tax (which currently applies only to estates valued at $5 million or more).

Romney has said he would offset the loss of personal income tax revenue (estimated at $360 billion a year by the Tax Policy Center) by reducing tax deductions and credits. And he has said he would do this while making sure that those at the top keep paying the “same share of the tax burden they’re paying now.”

But he has steadfastly refused to say which tax preferences would be cut or reduced. He has pointed to the revenue-neutral proposals for rate-cutting put forth by the deficit commission as evidence that what he proposes is possible in theory, but those proposals pay for the cuts largely by taxing capital gains at the higher rates that apply to ordinary income, a measure Romney has specifically ruled out.

So Romney has failed to produce evidence that what he promises is possible. And we judge that the weight of evidence and expert opinion is clear — it’s not possible.

Romney says this criticism ignores his separate plan to cut corporate tax rates, which he says will stimulate economic growth. Indeed, there’s evidence to suggest that cutting corporate taxes can do that, and the Tax Foundation expert (who supports Romney’s plan) suggests that more jobs would be an acceptable trade-off for a less progressive personal income tax system.

But how much growth to expect is debatable, especially because Romney proposes to cut only the corporate tax rate, not corporate taxes overall. He would offset the rate cut by eliminating tax preferences resulting in no loss of revenue. During the Bush administration, Treasury Department experts concluded that the corporate rate could be dropped to 28 percent without losing revenue (Romney proposes 25 percent), but that such a trade-off “might well have little or no effect” on economic growth.

Romney’s experts predict about a 1 percent increase in growth. One of the authors of the Tax Policy Center study says that is “implausibly large” and even if it materializes it wouldn’t prevent a tax increase on middle-income taxpayers under Romney’s income tax plan.

There’s room to argue that the benefits of increased growth are a fair trade for a less progressive tax system. In fact, that’s exactly the case made by the Tax Foundation’s expert, who notes that “the currently unemployed will receive the greatest benefit in the form of a job.”

But Romney’s claim that he can somehow slash individual income tax rates without losing federal revenue or favoring the wealthy remains at best unproven, and in our judgment, based on available evidence, impossible.

Analysis
The Evolution of a Tax Plan

Mitt Romney first revealed his tax plans on Sept. 6, 2011, in a 59-point economic plan titled “Mitt Romney’s Plan for Jobs and Economic Growth.” The former Massachusetts governor proposed maintaining the Bush-era income tax rates, repealing the estate tax and lowering the corporate tax from 35 percent to 25 percent and broadening its base. The plan was criticized by the Wall Street Journal as “surprisingly timid.”

The campaign expanded it on Feb. 22, 2012, to include repealing the Alternative Minimum Tax and cutting the marginal income tax rates by an additional 20 percent across the board. The Wall Street Journal quoted Romney as saying “he would direct Congress to make up lost revenue from the rate cuts by limiting deductions, mostly for wealthier Americans.”

Wall Street Journal, Feb. 23: In describing his plan Wednesday, Mr. Romney pledged to preserve popular deductions for mortgage interest and charitable donations for middle-income families.

“For high-income folks, we’re going to cut back on that so that we make sure that the top 1% keeps paying the current share they’re paying or more,” Mr. Romney said. “We want middle-income Americans to be the place we focus our help, because it’s middle-income Americans that have been hurt by this Obama economy.”

A couple of months later, Romney was overheard telling donors that he would “probably eliminate” the mortgage-interest deduction for second homes for high-income taxpayers and possibly eliminate deductions for state income taxes and local property taxes. But the Romney campaign later retracted those comments, saying that he was offering some possible options — not making policy proposals. He has yet to offer any specifics.

A $250,000 Cut for ‘Millionaires’

In March, the nonpartisan Tax Policy Center did an analysis of Romney’s corporate, individual and estate tax plan and found it would cost $480 billion a year, or $4.8 trillion over 10 years, beginning in calendar year 2015. At that time, the Tax Policy Center said it did not attempt to gauge the impact of eliminating or reducing tax deductions, credits and exemptions “ecause we have received no details on proposals to reduce tax preferences.”

The TPC’s detailed calculations showed that — before any reduction of tax deductions — Romney’s plan would result in 99.97 percent of those making $1 million a year or more getting a tax cut (compared with what they pay now) and that the cuts would average $256,603 each. But further down the income scale, the benefit would be considerably less. For those making between $50,000 and $75,000, for example, 94 percent would see a tax cut, and it would average $1,226, before any loss of deductions or credits. These cuts are all in addition to those enacted during the Bush administration, and Romney would not allow those to expire as scheduled.

We should add here that TPC’s analyses are generated using the same sort of computer modeling of the tax system used by the U.S. Treasury and the Congressional Budget Office. We haven’t seen Romney dispute these figures. In fact, when the TPC issued findings on Texas Gov. Rick Perry’s tax plan earlier in the GOP nomination fight, Romney issued a press release calling the analysis “objective.”

Nevertheless, Romney has insisted that under his tax plan — once he releases the rest of it — the wealthy would pay the same share of the tax burden that they do at present. “I’m not looking for a tax cut for the very wealthiest,” Romney told Bob Schieffer on June 17 on CBS’ “Face the Nation.”

[b]Romney, June 17: … my view is the right way to do that is to limit them [tax preferences] for high-income individuals because I want to keep the progressivity of the code. One– one of the absolute requirements of any tax reform that I have in mind is that people who are at the high end, whether you call them the 1 percent or 2 percent or half a percent, that people at the high end will still pay the same share of the tax burden they’re paying now. I’m not looking for a tax cut for the very wealthiest. I’m looking to bring tax rates down for everyone, and, also, to make sure that we stimulate growth by doing so and jobs.

But, when pressed for specifics, Romney told Schieffer that he will “go through that process with Congress as to which of all the different deductions and exemptions” will be eliminated or reduced. In that interview, he said the National Commission on Fiscal Responsibility and Reform issued a report in December 2010 that proved it is “mathematically … possible” to reduce tax rates and reduce the deficit.

That’s true — but Romney failed to note that the commission’s illustrative tax-reform proposal “taxes capital gains and dividends as ordinary income” (see footnote on page 29), eliminating a tax break that benefits mostly those with high incomes. But Romney’s tax plan would “[m]aintain current tax rates on interest, dividends, and capital gains,” taking that option off the table. Under current law, capital gains (profits on sale of stock or real estate, for example) are generally taxed at a top rate of 15 percent, while ordinary earnings from salaries or business are taxed at a top rate of 35 percent of income over $388,350. (If the Bush-era tax cuts are allowed to expire, the rate would return to 20 percent.)

So how can Romney design a revenue-neutral plan that would cut income tax rates without disproportionately benefiting the wealthiest, and still maintain the current low rates on capital gains and dividends? That was the subject of the Tax Policy Center’s latest report, which immediately renewed the debate over who would benefit — and who would not — under Romney’s tax plan.

A Tax Debate, Renewed

The Tax Policy Center issued its report Aug. 1. It’s called “On the Distributional Effects of Base-Broadening Income Tax Reform.” The report was co-authored by William G. Gale, a former staff economist in President George H.W. Bush’s White House in 1991-1992, and Adam Looney, a former senior economist in the Obama White House.

TPC makes clear that the report is not an analysis of “Governor Romney’s plan directly, as certain components of his plan are not specified in sufficient detail, nor do we make assumptions regarding what those components might be.”

Rather, the center studied the impact of “a revenue-neutral individual income tax change that incorporates the features Governor Romney has proposed.” The center determined that Romney’s proposals for individual and estate taxes would cost about $360 billion a year, beginning in 2015. Offsetting such steep revenue losses by curbing tax preferences “would require deep reductions in many popular tax benefits,” TPC said.

Tax Policy Center, Aug. 1: Offsetting the $360 billion in revenue losses necessitates a reduction of roughly 65 percent of available tax expenditures. Such a reduction by itself would be unprecedented, and would require deep reductions in many popular tax benefits ranging from the mortgage interest deduction, the exclusion for employer-provided health insurance, the deduction for charitable contributions, and benefits for low- and middle-income families and children like the EITC and child tax credit.

The center concluded it is not mathematically possible to design a revenue-neutral plan without providing “large tax cuts” to high-income households.

Tax Policy Center, Aug. 1: Our major conclusion is that a revenue-neutral individual income tax change that incorporates the features Governor Romney has proposed – including reducing marginal tax rates substantially, eliminating the individual alternative minimum tax (AMT) and maintaining all tax breaks for saving and investment – would provide large tax cuts to high-income households, and increase the tax burdens on middle- and/or lower-income taxpayers.

That was true even though the TPC eliminated or reduced tax expenditures “starting at the top” in an attempt to maintain the progressive nature of the tax code — one of Romney’s stated goals. “Even after eliminating all available tax expenditures for households earning more than $200,000, this group still faces a net tax break.”

On the day of the report’s release, President Obama renewed his attack on Romney’s plan in a speech in Ohio.

Obama, Aug. 1: The bulk of this [tax cut] would go to the wealthiest Americans. A lot of it would go to the top 1 percent. Pay attention here — folks making more than $3 million a year — the top one-tenth of 1 percent — they would get a tax cut under Mr. Romney’s plan that is worth almost a quarter of a million dollars — $250,000 they would save under his plan.

It’s true that the report (page 19) said that those in the top 0.1 percent of taxpayers would receive a $246,652 net tax break. But, as we noted earlier, it’s not “under Romney’s plan,” as the president said. It’s under a set of assumptions used by the Tax Policy Center to raise $360 billion a year in revenue by eliminating or reducing tax expenditures.

The report, however, does support Obama’s larger point that Romney’s plan would likely disproportionately benefit the wealthy.

The Romney campaign dismissed the Tax Policy Center report as “biased,” saying it “ignores the positive benefits to economic growth” that would come from other parts of his tax plan — such as reducing the corporate tax rate from 35 percent to 25 percent and broadening the base. In announcing his revised plan in February, Romney said that his entire tax plan — including the corporate tax cuts — will be paid for through a combination of cutting spending, broadening the corporate tax base, and placing “some curbs on personal tax deductions, exemptions and credits.”

It is true that the center’s report did not consider the impact of the corporate tax changes. The report said: “Any reductions in revenue due to the lower corporate rate would be offset by reducing corporate tax preferences. As a result, we examine only changes to the individual income tax, alternative minimum tax, payroll tax, and estate tax. We ignore the effect of the proposal to reduce the corporate rate to 25 percent.”

William McBride of the Tax Foundation, a pro-business nonprofit that supports Romney’s plan, writes that reducing the corporate tax rate will spur 1 percent to 2 percent more economic growth.

But McBride also writes that TPC “correctly identified the Romney plan as a tax cut, at least in static terms, that accrues mainly to high-income earners.” That’s not a bad thing, he argues, because the U.S. already has “the most progressive income tax system in the industrialized world,” and it is “well past time to consider the costs and benefits of such an extremely progressive system.”

But there’s reason to doubt that Romney’s corporate tax-rate cut would produce the growth that Romney and McBride predict. McBride cited an economic study from 2004, which looked at data from 70 countries and cited estimates suggesting that cutting the corporate tax rate by 10 percentage points can increase the annual growth rate by around 1.1 percent or 1.8 percent, depending on the method used.

But Romney would offset his rate cut by eliminating corporate tax preferences in order to bring in the same amount of revenue. When the Treasury Department’s Office of Tax Policy looked at such a plan in 2007 (under President George W. Bush), it concluded that it was possible to cut the top corporate rate to 28 percent without losing revenue through various base-broadening provisions. But it also warned that “little or no” economic growth might result (see page 48):

U.S. Treasury, Dec. 20, 2007: The Treasury Department estimates that the combined policy of base broadening and lowering the business tax rate to 28 percent might well have little or no effect on the level of real output in the long run because the economic gain from the lower corporate tax rate may well be largely offset by the economic cost of eliminating accelerated depreciation.

If accelerated depreciation is maintained, Treasury estimated that the top corporate rate could be cut only to 31 percent without losing revenue. That would result in a long-run increase of 0.5 percent in economic output, Treasury said.

The Romney campaign insists that economic growth will somehow make its tax plan work as promised, but we’ve seen nothing to support that. Romney’s experts predict about a 1 percent increase in growth. Looney, one of the authors of the Tax Policy Center study, calls that “an implausibly large estimate,” but nevertheless ran the study again assuming that growth rate and an additional 12 million jobs. The result, he told ABC News, is that it would offset only about 15 percent of Romney’s revenue loss from individual tax cuts.

“Even in that case, there’s still a shift in the tax burden from high-income taxpayers to low- and or middle-income taxpayers,” Looney told ABC News. “It’s smaller, but it would require a net tax increase on the middle class.”

The Tax Foundation’s McBride argues that a less progressive income tax system is still a good trade-off for increased economic growth. “[L]ower rates combined with a broader tax base should lead to significant economic growth,” McBride writes. “The benefits of such growth will benefit some more than others, but arguably the currently unemployed will receive the greatest benefit in the form of a job.”

Here we should note that the study McBride cites to support his prediction of a 1 percent to 2 percent increase in growth refers only to the effect of a corporate rate cut, not a cut in individual rates. That study, using data from 70 countries, concluded that tax rates on individual labor — whether it’s the average rate or the top marginal rate — “are not significantly associated with economic growth.”

But Romney is not arguing that more jobs and growth should compensate for a tax system that puts a greater burden, or a larger share of a reduced burden, on middle-income taxpayers. He’s promising that the share of taxes won’t change. He has failed to prove that’s possible. And based on available evidence, we don’t see that it is.
