Three Powerful Arguments For A Simple And Fair Flat Tax
Dan Mitchell, International Liberty
There are many powerful arguments for junking the internal revenue code and replacing it with a simple and fair flat tax.
- It is good to have lower tax rates in order to encourage more productive behavior.
- It is good to get rid of double taxation in order to enable saving and investment.
- It is good the end distorting preferences in order to reduce economically irrational decisions.
Today, let’s review a feature of good tax reform that involves the second and third bullet points.
Under current law, there is double taxation of corporate income. This means that companies must pay a tax on income, but that the income is then taxed a second time when distributed to the owners of the company (i.e., shareholders).
This means that the effective tax rate is a combination of the corporate income tax rate and the tax rate imposed on dividends. And this higher tax rate is an example of why double taxation discourages capital formation and thus leads to lower wages.
But this double taxation of dividends also creates a distortion because there isn’t double taxation of corporate income that is distributed to bondholders. This means companies have a significant tax-driven incentive to rely on debt, which is risky for them and the overall economy.
Curtis Dubay has a very straightforward explanation of the problem.
In debt financing, a business raises money by issuing debt, usually by selling a bond. In equity financing, a business raises funds by selling a share in the business through the sale of stock. The tax system provides a relative advantage to financing capital expenditures through debt because under current tax law, businesses can deduct their interest payments on the debt instruments, but dividend payments to shareholders are not deductible. Thus, equity is disadvantaged because it is double taxed while debt correctly faces only a single layer of taxation.
