On Wednesday the Tax Foundation released the updated State Business Tax Climate Index by Mark Robyn. Wyoming, South Dakota, and Nevada ranked highest on the index because they have low overall tax burdens and tax policies that introduce minimal distortions to business behavior.
The three states at the bottom of the ranking — New Jersey, New York, and California — were also the worst-ranked states last year. Unsurprisingly, these three states are also experiencing domestic outmigration as individuals and businesses leave for locations with lower tax burdens. A study by Jed Kolko, David Neumark, and Marisol Cuella Mejia demonstrates that the SBTCI is one of the most accurate indexes for predicting economic outcomes.
Illinois had the largest change in ranking over last year’s, dropping 12 spots. Robyn writes on the importance of tax policy in business decisions:
Anecdotes about the impact of state tax systems on business investment are plentiful. In Illinois early last decade, hundreds of millions of dollars of capital investments were delayed when then-Governor Blagojevich proposed a hefty gross receipts tax. Only when the legislature resoundingly defeated the bill did the investment resume. In 2005, California-based Intel decided to build a multi-billion dollar chip-making facility in Arizona due to its favorable corporate income tax system. In 2010 Northrup Grumman chose to move its headquarters to Virginia over Maryland, citing the better business tax climate. Anecdotes such as these reinforce what we know from economic theory: taxes matter to businesses, and those places with the most competitive tax systems will reap the benefits of business-friendly tax climates.
The Tax Foundation is not alone in finding these states relatively lacking in economic freedom. Indexes developed by the Mercatus Center and the American Legislative Exchange Council also ranked these states as among the least economically competitive in the country.
While lawmakers may be tempted to try to improve their states’ rankings in these types of indexes with special business tax breaks or increasing state spending, all three studies demonstrate that the best way to improve a state’s competitiveness ranking is to provide a climate of low, stable taxes that do not favor specific industries.
