Higher Top Tax Rate Will Slow Economic Performance

April 6, 2011

A new study from the Adam Smith Institute in the United Kingdom provides overwhelming evidence that class-warfare tax policy is grossly misguided and self-destructive, says Daniel J. Mitchell, a senior fellow with the Cato Institute.

  • The authors examine the likely impact of the 10-percentage point increase in the top income tax rate, which was imposed as an election-year stunt by formerprime minister Gordon Brown and then kept in place by his successor, David Cameron.
  • They find that boosting the top tax rate to 50 percent will slow economic performance.
  • And because of both macroeconomic and microeconomic responses, tax revenues over the next 10 years are likely to drop by the equivalent of more than $550 billion.

President Obama wants to impose similar policies in the United States and there is every reason to expect similarly poor results, says Mitchell.
