In the coming weeks, we will break down our recently released 2018 State Business Tax Climate Index with several maps illustrating corporate, individual, sales, property, and unemployment insurance 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. rankings. Today, we look at corporate taxes.
The corporate tax component of our Index measures the impact of each state’s principal tax on business activities and accounts for 19.0 percent of each state’s total score.
Unlike other studies that look at overall tax burdens, the Index focuses on the structure of each state’s tax system. Our corporate tax component, for example, scores states not just on rates and brackets, but on how well they handle net operating losses, whether the state levies an economically harmful gross receipts-style tax, and whether a state indexes its brackets to inflation, among other things.
