ILLINOIS PERSONAL INCOME GROWTH 2ND LOWEST IN U.S. SINCE GREAT RECESSION by Illinois Policy.
Only Mississippi has fared worse than Illinois in personal income growth since the Great Recession hit at the end of 2007. Analysis shows state income taxes matter.
Recovery from the Great Recession has been uneven among U.S. states, but Illinois has especially struggled, according to a recent analysis from The Pew Charitable Trusts.
Illinois underperformed every state except for Mississippi in growth of personal income. The U.S. average was a 2.1% inflation-adjusted compound average annual growth rate since the recession, but Illinois averaged only 1.1% a year.
A deeper look at the data by the Illinois Policy Institute shows one common factor in personal income recovery is state income tax policy
States with more competitive income tax policies such as no-income tax states or states with low, flat income taxes, on average, have experienced stronger personal income growth both since the recession and in the most recent 12-month period. States with progressive income tax rates have experienced the slowest growth in personal income and also have higher income tax burdens on average. Four of the five worst-performing states for personal income growth have progressive income taxes.
Those with flat income taxes have performed better than their progressive income tax peers, but still lag the performance of states with no income tax. Of the top performing states, 4 out of 5 have either a flat income tax or no income tax, the exception being North Dakota, which benefited from a large natural resource boom and levies a top marginal tax rate of 2.9%. North Dakota’s personal income growth benefited from the fracking boom that occurred shortly before the start of the recession, although growth in recent years has faltered due to fluctuations in the price of oil.
California, a state with one of the highest income taxes in the nation, has ranked 6th in terms of personal income growth since the beginning of the recession, benefitting from annual population growth that exceeds the national median and is characteristic of most western states. While California’s 10-year performance has been stronger than all neighboring states, the opposite is true for the past year, with personal income growth lagging all neighboring states.
States with progressive income taxes have higher income tax burdens on average and have generally lagged their peers. This is unsurprising, as the relationship between economic growth and income tax policy is well established. Higher taxes have negative effects on the economy, and progressive income taxes are more damaging to the economy than equivalent flat income taxes.
While there are many policy factors that may be pushing a state’s performance up or down, all state economies would likely benefit from lower and flatter income taxes. For example, a friendlier tax climate could have resulted in even stronger personal income growth for California and prevented the state from lagging neighbors in 2019.
The analysis from Pew highlights several common themes. First, South and West region states have generally been experiencing the strongest income growth, while Midwest and Northeast states have lagged during the recovery. This trend also holds with population growth.
Besides North Dakota, the top states in personal income growth are Utah, Washington, Texas and Colorado. Each experienced much more consistent growth year over year. These states have all been experiencing more rapid population growth compared to the rest of the country, a common sign of a healthy labor market and economic growth.
States performing the worst have been Mississippi, Illinois, Connecticut, Rhode Island, and West Virginia. These are among the states with the lowest population growth, with each state experiencing at least one year of population loss since the recession. Illinois and Connecticut have had population decline for six consecutive years, and West Virginia has experienced seven consecutive years of population decline.
Long-run economic growth is closely related to population growth. Population growth represents a growing workforce and consumer base that allows businesses to confidently invest, knowing that they will be able to find workers and consumers for their products. Similarly, workers are more easily able to secure employment and enjoy increases in their incomes in healthy, growing economies. Regardless of which factor leads to the other, population and income growth are closely related and pose serious concerns for states such as Illinois.
As Illinoisans are being asked to approve a progressive income tax at the ballot on Nov. 3 and politicians promise that it will be a magic pill for all of the state’s problems, it is important to keep analysis like this in mind. Illinois suffers from population loss, and shrinking states face more economic challenges.
The Illinois Policy Institute’s analysis of our state’s slow growth since the recession highlights again the trouble progressive income tax states have in fostering a healthier labor market relative to their peers. If Illinois adopts a progressive income tax, it won’t be to grow the state’s population, its economy or its labor market.
