Corporate tax rates and economic growth since 1947 | Economic Policy Institute
"The top statutory corporate tax rate has been falling since the early 1950s. The top corporate tax rate was 52 percent throughout the Eisenhower administration—17 percentage points higher than the current top rate of 35 percent. U.S. GDP grew by almost 4 percent annually in the 1950s compared with a 1.8 percent growth rate in the 2000s. On the surface, it would appear that more robust economic growth is associated with higher corporate tax rates. Further analysis, however, finds no evidence that either the statutory top corporate tax rate or the effective marginal tax rate on capital income is correlated with real GDP growth."
