Do lower income tax rates bring in more tax revenue to the treasury or less revenue to the treasury?

Answer 1

The simple answer to your question is that (in theory) tax reduction stimulates the economy, which increases income. It often (NOT ALWAYS, because that is not the primary reason)results in more income tax; that is,a lower tax rate on a larger tax base.

Answer 2

It depends more on the economy.

Clinton: Raised taxes in the early 90's. Tax Revenues increased and the economy boomed.

Bush: Lowered taxxes in the 2000's. Tax Revenues increases and the economy grew...though slower.
