The Corporate Income Tax

Should the U.S. Corporate Income Tax be increased from its current 21% (plus state corporate income taxes that average about 5%) back to 28%? No, it should be reduced to zero. The corporate income tax should be abolished. Only people pay taxes, either workers from their wages, consumers in the prices they pay goods and services, or shareholders from their business incomes. The corporate income tax, taxes these people twice.  So who really pays a corporate income tax?

One of the standards applied by economists for a “good” tax is that it does not distort the allocation of resources. If tax treatment encourages investments that are less productive than otherwise, output will be lower, and we will be poorer. This is called the tax neutrality principle. “Next up: tax-reform”  The corporate income tax violates this principle because it taxes the same income twice contributing to a bias toward debt rather than equity financing. The activities of corporations generate wage income to its workers, which is taxed as income of its workers. Their purchases of supplies and services from other companies generate income for those companies, which are taxed there. The difference between a corporation’s revenue on its sales and these expenditures–its profit–is paid to its owners (shareholders) and is taxed as part of their incomes.

But corporate income is taxed again in the name of the company itself–double taxation. That tax must come from some combination of reduced employee remuneration (wages and benefits) and shareholder income.  Studies indicate that it comes largely from reduced wages. https://www.forbes.com/sites/johngoodman/2021/04/02/who-pays-the-corporate-income-tax/?sh=4eb92e9b58ab

Another problem with this double tax on corporate income is that many corporations operate in many countries. It is not easy (if even possible) to agree with each of these countries, which have their own tax policies, which income to tax in which country. Companies have become expert at shifting their activities and attributing income to the lowest tax jurisdictions.  Where, for example, is the intellectual property, which can be an important source of company’s income, owned for tax purposes? The answer is often Ireland.

Economists agree that the most neutral tax is a flat rate consumption (sales) tax.  “The Principles of Tax Reform” Consumption would be taxed were it takes place thus avoiding the issues in current income taxes of where the income is produced. In our global, internet linked world, the applicable consumption tax would be the one levied on the residence of the consumer as it finances the government services provided there.

In an earlier note on a Universal Basic Income, I presented back-of-the-envelop estimates of the consumption tax rate required to finance a UBI of 18,000 dollars per year for each and every adult and half of that amount for children (under 20 years old) if we abolish all income taxes (individual and corporate) and replace existing entitlement programs (Social Security, Medicare, Medicaid, food stamps, unemployment insurance, etc.) with that UBI. The combination of a flat rate consumption tax and a UBI produces an interesting degree of tax progressivity relative to income. I hope that you find it interesting. “Replacing Social Security with a universal basic income”

What is SALT really about?

Here is the proper way to understand the SALT issue—whether State and Local Taxes should be deducted from taxable income on which federal taxes are levied.

Assume that taxpayer 1 (Jack) in state A and taxpayer 2 (Mary) in state B both have earned incomes of $150,000 each. If Uncle Sam needs to raise $60,000 each year from its income tax and applies a flat tax on each taxpayers’ total income, it would need to impose a tax rate of 20% (150,000+150,000=300,000*0.2=60,000). Each taxpayer would pay $30,000 in federal taxes.

Assume that Jack chooses to buy an expensive car costing $100,000 while Mary makes a more frugal choice and buys a $40,000 car. No one would think that they should be allowed to deduct the cost of their cars from their incomes for purposes of their federal income tax, but what if they could? Jack would now have $50,000 in federally taxable income (150,000-100,000) while Mary would have taxable income of$110,000 (100,000-40,000). To raise the same $60,000 needed by the Feds, the federal tax rate would need to be increased to 37.5% (50,000+110,000=160,000*0.375=60,000). Of the $60,000 in federal tax revenue, Jack would pay $18,750 (50,000*0.375) and Mary would pay $41,250 (110*0.375). Not only does Jack get a better car but he also pays less taxes. In fact, this tax treatment subsidizes Jack’s expensive car to the amount of $11,250 (30,000-18,750). This is likely to lead Jack to buy a more expensive car than he would have chosen if spending only his own money. Clearly that would be neither fair nor economically efficient.

Replace “car” in the above example with “state government expenditures”. Jack may well choose to have (and pay the higher taxes to finance) more extensive state government services than does Mary. That is fine as long as you are free to choose whether you live in state A or state B. But should Mary be forced to pay (subsidize) some of Jack’s tastes for larger state government expenditures? Surely not, but that is exactly what allowing tax payers to deduct their SALT from their taxable income for federal tax purposes does. Eliminating that deduction would restore fairness and remove any artificial inducement for larger state expenditures. In this way, every one would be free to support the level of state spending they are willing to pay for.
