The tax experts we spoke with agreed with Stockman. In this climate, raising the top tax rates from 35 to 39.6 percent would increase revenues. The effect Pence is talking about would not happen at this level of taxation, they said.
"There is some rate at which it would be true," said Roberton Williams of the nonpartisan Tax Policy Center. "But I don't think there are any established economists who would argue that we're near that."
"At current tax rates, most tax increases will increase revenues, at least in the short and medium run," said Brian Riedl of the conservative Heritage Foundation. "The caveat is that in a fragile economy, it can be unpredictable."
"There is no real dispute among economists that broad-based federal income tax cuts reduce revenue (except when tax rates are much higher than they are now)," said Alan D. Viard of the conservative American Enterprise Institute. "Revenue is lower than it would be without the Bush tax cuts -- liberal and conservative economists are in accord on this question."
To recap, Pence said that, "Anybody who is familiar with the historical data from the IRS knows that raising income tax rates will likely actually reduce federal revenues." Actually, the historical data doesn't show that. Experts said the economic theory Pence is drawing from doesn't apply in the current situation, and an increase in tax rates would not cause tax revenues to decline. So we rate his statement False.
