Here’s the bottom line on taxes

On tax day, which is today this year, everyone’s in favor of tax reform. Nobody can survive the ordeal of preparing a federal income tax return without concluding that there must be a simpler, fairer way to pay for government.

And so — as inevitably as death and, well, you know — the presidential campaigns promise us some kind of tax reform.

President Obama spent much of last week promoting his “Buffett rule,” a proposal to require anyone who makes more than $1 million year to pay federal taxes at a minimum of 30 percent. It’s a matter of basic fairness, he says.

Mitt Romney, the presumptive Republican candidate, rejects the Buffett rule — and all other tax increases, for that matter. He says he’d reform the system by lowering tax rates for everybody and pay for it by reducing tax deductions and cutting federal spending.

And there’s the problem: Both candidates claim they want “tax reform,” but when they say those words, they’re really talking about other things.

Talking point

Obama’s Buffett rule wouldn’t clean up the tax code; in fact, it would add more complexity. It’s a campaign talking point framed as an easily understandable appeal for equity.

Obama says he’s for comprehensive tax reform, but he’s never offered a full-scale tax plan, merely a bare-bones list of principles (lower rates, simplification) stapled to proposals that don’t always easily fit them (higher rates for the wealthy, the Buffett rule).

Romney’s “reform” isn’t much better. His proposal is really about reducing the burden on upper-income taxpayers and shrinking the federal government, not fixing the tax code. It’s an appendix to his overall budget plan, which would reduce federal domestic spending by at least $500 billion (by 2016) while increasing military spending.

Romney says he wants to limit the deductions, exemptions and credits that upper-income taxpayers can claim. But his plan specifies nothing.

So what sounds like a campaign debate over taxes is really just 2012’s version of the perennial argument over the proper size and scope of the federal government. How we pay for it — the shape of the tax system — is an afterthought. Oddly, that may not be a bad thing. As Obama’s former economic advisor Larry Summers wrote recently, an election campaign is a bad place to make wise tax policy.

“The more tax issues are discussed during the campaign,” Summers wrote in the Financial Times, “the more the candidates will be driven to make ... pledges that might make tax reform that much more difficult.”

And it is difficult. But not because the sides are miles apart. Among policy wonks and thoughtful politicians, there’s a fair amount of bipartisan consensus that, to achieve efficiency, fairness and simplicity, we need fewer tax incentives that distort economic decisions. Even Obama and Romney agree in theory on the basic principles: establish lower tax rates (on most taxpayers, at least) and a broader tax base (meaning fewer deductions and exclusions).

The problem with getting it done is this: Everyone loves lower tax rates. But almost everyone also loves his or her favorite tax deduction.

‘Tax expenditures’

The easiest, most efficient way to lower tax rates and streamline the tax system would be to eliminate the deductions and exclusions that shelter big chunks of income from taxation.

But look at the three biggest tax expenditures last year. First comes the tax-free treatment of health insurance premiums paid by employers; in 2008, Republican candidate John McCain proposed abolishing it as a sensible economic move, and Obama denounced that as a heartless attack on healthcare. Second, the mortgage interest deduction, which the real estate industry promotes as help for first-time home buyers even though it also subsidizes million-dollar vacation homes. Third: tax deductible contributions to 401(k) retirement plans. No politician is eager to wade into the buzz saw of protests that would greet a proposal to abolish any of those.

That helps explain why our last big tax reform, in 1986, came between presidential elections. It took a second-term president, Ronald Reagan, who was broadly popular; a House of Representatives with a secure Democratic majority; a healthy economy; and a declining federal deficit to eliminate dozens of loopholes and reduce the top marginal tax rate to 28 percent. (It crept back up to 39.6 percent by 1993; it’s currently 35 percent.)
