Ranking Corporate Income Taxes on the 2020 State Business Tax Climate Index

In the coming weeks, we will break down our recently released 2020 State Business Tax Climate Index with maps illustrating each of the five major components of the Index: corporate, individual, sales, property, and unemployment insurance taxes. Today we look at states’ rankings on the corporate tax component, which accounts for 19.7 percent of each state’s overall rank.

The corporate taxA tax is a mandatory payment or charge collected by local, state, and national governments from individuals or businesses to cover the costs of general government services, goods, and activities. component of our Index measures each state’s principal tax on business activities. Most states levy a corporate income tax on a company’s profits (receipts minus most business expenses, including compensation and the cost of goods sold), while some states levy gross receipts taxes, which allow few or no deductions for a company’s expenses.

Unlike other studies that look solely at tax burdens, the Index measures how well or poorly each state structures its tax system. It is concerned with the how, not the how much, of state revenue, because there are better and worse ways to levy taxes. Our corporate tax component, for example, scores states not just on their corporate tax rates and brackets, but also on how they handle net operating losses, whether they levy gross receipts-style taxes (which are more economically harmful than corporate income taxes), whether businesses can fully expense purchases of machinery and equipment, and whether states index their brackets for inflation, among other factors.
