Grading Perry’s Flat Tax: Some Missing Homework, But a Solid B+
by Dan MitchellGovernor Rick Perry of Texas has announced a plan, which he outlines in today’s Wall Street Journal, to replace the corrupt and inefficient internal revenue code with a flat tax. Let’s review his proposal, using the principles of good tax policy as a benchmark.
1. Does the plan have a low, flat rate to minimize penalties on productive behavior?
Governor Perry is proposing an optional 20 percent tax rate. Combined with a very generous allowance (it appears that a family of four would not pay tax on the first $50,000 of income), this means the income tax will be only a modest burden for households. Most important, at least from an economic perspective, the 20-percent marginal tax rate will be much more conducive to entrepreneurship and hard work, giving people more incentive to create jobs and wealth.
2. Does the plan eliminate double taxation so there is no longer a tax bias against saving and investment?
The Perry flat tax gets rid of the death tax, the capital gains tax, and the double tax on dividends. This would significantly reduce the discriminatory and punitive treatment of income that is saved and invested (see this chart to understand why this is a serious problem in the current tax code). Since all economic theories – even socialism and Marxism – agree that capital formation is key for long-run growth and higher living standards, addressing the tax bias against saving and investment is one of the best features of Perry’s plan.
3. Does the plan get rid of deductions, preferences, exemptions, preferences, deductions, loopholes, credits, shelters, and other provisions that distort economic behavior?
A pure flat tax does not include any preferences or penalties. The goal is to leave people alone so they make decisions based on what makes economic sense rather than what reduces their tax liability. Unfortunately, this is one area where the Perry flat tax falls a bit short. His plan gets rid of lots of special favors in the tax code, but it would retain deductions (for those earning less than $500,000 yearly) for charitable contributions, home mortgage interest, and state and local taxes.
As a long-time advocate of a pure flat tax, I’m not happy that Perry has deviated from the ideal approach. But the perfect should not be the enemy of the very good. If implemented, his plan would dramatically boost economic performance and improve competitiveness.
