Feldstein Says Lower Corporate Tax Rates

See Want to Boost the Economy? Lower Corporate Tax Rates: The increased flow of capital to the U.S. would result in greater productivity and higher real wages, from today's WSJ. He shows that even with deductions and loopholes, and combining the federal and state taxes together, the US has the highest corporate taxes in the world. This drives capital out of the US. Excerpts:

"The U.S. corporate tax rate is 35% at the federal level and 39% when the average state corporate tax is included. The average rate in the other industrial countries of the Organization for Economic Cooperation and Development (OECD) is just 25%. Only Japan has as high a rate.

Eliminating every loophole in the taxation of domestic corporate profits identified by the administration's own Office of Management and Budget would raise less than $60 billion of extra revenue in 2011, enough to lower the combined federal-state corporate rate to 35%. The U.S rate would still be higher than in every other country but Japan, and a full 10 percentage points higher than the average in other industrial OECD countries.This high corporate tax rate causes a misuse of our capital stock. More specifically, the high rate drives capital within the U.S. economy away from the corporate sector and into housing and other uses that do not increase productivity or raise real wages. And because interest payments by companies are deductible in calculating taxable profits, the high tax rate induces firms to use too much debt to finance their operations, increasing risks for them and the U.S. economy.

Moreover, the difference between the U.S. corporate tax rate and the lower rates abroad encourages U.S. firms to locate production in foreign countries and discourages foreign firms from producing in the U.S. unless absolutely necessary. The result is less capital at home, reduced productivity, and therefore lower real wages.

Our high corporate tax rate also makes the cost of capital higher for American firms than for their foreign competitors, forcing them to charge higher prices on American products. That makes U.S. producers less able to compete in global markets or with imports to the U.S. from abroad.

All this is compounded by the unusual way in which U.S. firms are taxed on overseas incomes. Firms in every country pay taxes on the profits they earn at home and pay taxes to foreign governments on the profits they earn abroad. Generally, however, foreign firms pay only a small token tax if they bring their after-tax profits back to their home country.

But that's not how it works for American firms. Our companies must pay the difference between the U.S. tax rate and the tax that they have already paid. For example, French and American firms that invest in Ireland pay a corporate tax of only 12.5% to the Irish government. The French firm can then bring its after-tax profit back to France by paying less than 5% on those repatriated profits while an American firm would have to pay the 22.5% difference between our 35% corporate tax and the 12.5% Irish tax.

The extra tax that American firms must pay when they repatriate foreign profits encourages those firms to leave profits abroad, investing those funds to expand foreign operations instead of bringing that money back to invest in new plants and equipment at home. The extra tax paid by U.S. firms when repatriating profits also raises the effective cost of capital to American firms operating in other countries, making them less able to compete in those markets. That shrinks their scale of global production, reducing the cost savings that would result from spreading domestic R&D and other fixed costs over a larger volume of sales."
