A broad base is an essential element of a good tax system. Fulfilling the principles of "horizontal equity," and "economic neutrality," both depend upon the use of a broad tax base. Unfortunately, the temptation to carve out special tax breaks for politically popular causes, or for powerful constituencies, if often irresistible to lawmakers.
But efforts are currently underway in Michigan to undo some of these special tax breaks, and a tax reform commission in California is at least pretending to consider a reform that would help pave the way for a careful reconsideration of many of that state's tax breaks. Furthermore, policymakers in North Carolina have expressed a strong desire to return to the task of base-broadening this fall, even as efforts to include base-broadening revenue-raisers in this year's budget agreement seem to have failed.
Earlier this month, Michigan Governor Jennifer Granholm stated her desire to eliminate between $500 million and $1 billion in special tax breaks as a way to reduce the state's looming deficit. While accomplishing such a feat will inevitably involve an uphill political battle, Michiganders should be grateful that the Michigan League for Human Services (MLHS) is closely following the action. MLHS Chairman Lynn Jondahl hit the nail on the head when he urged lawmakers to ask themselves, in reference to the state's film tax credit, "Would you be willing to appropriate $6 million to MGM, say, to make this film in Michigan? We're paying you to do something in lieu of filling pot holes or funding mental health treatment. Which do we value more?"
In California, a tax reform commission that so far has shown interest mostly in cutting the progressive income tax is at least listening politely to a different idea. The so-called "blue proposal" currently before the commission, presented as a less regressive alternative to the much-ballyhooed flat-tax proposal supported by Governor Schwarzenegger, would require special tax breaks to be presented in the Governor's budget, saddled with a "sunset" provision, and evaluated based on their effectiveness in achieving their stated objectives. Of course, adopting this approach will amount to rearranging deck chairs on the Titanic if the commission acts on its apparent zeal for moving away from income taxes and towards regressive consumption taxes. And the "blue proposal" has its warts as well: provisions that would impose a spending cap and create a new "net receipts" tax in lieu of the current corporate income tax have progressives feeling, well, blue. But the tax-expenditure element of the "blue proposal" is a welcome dose of thoughtful policy at a time when California surely needs it.
Finally, in a recent development out of North Carolina, base-broadening appears to be off the agenda for the immediate future, though policymakers have expressed a strong interest in returning to the issue this fall. When they do return to the issue, they would be wise to review these recommendations, recently released from the North Carolina Budget and Tax Center, explaining how to broaden the state's tax base while simultaneously offsetting any potentially harmful effects on low- and moderate-income families.
