Does broadening the tax base raise more revenue than higher top rates?
Core argument: Raising top tax rates to 70% would generate less than one-third of the revenue produced by a base-broadening approach, indicating inefficiency in targeting high earners.
Increasing top tax rates to 70% would raise less than one-third of the revenue compared to a base-broadening approach, highlighting inefficiencies in targeting high earners. The elasticity of taxable income suggests a 1% increase in top rates reduces reported income by 0.6%, as individuals engage in tax avoidance. This results in high economic distortion relative to revenue raised, especially with proposals pushing rates over 80% in areas like NYC. Broadening the tax base can lower elasticities, making it harder for the wealthy to shield income. Thus, traditional tax reform, focusing on efficient and progressive revenue generation through base broadening, should precede any consideration of wealth taxes or high-income rates, avoiding a confrontational approach with successful individuals.
