Proposals to spend the state's $1.9 billion surplus in this year's legislative session are quickly being framed as a choice between tax relief for overburdened businesses and individuals or investments in the common good. In fact, there are persuasive cases to be made for both thoughtful tax reform and smart spending. But the best choices will be made if Minnesotans treat the surplus for what it is — a temporary windfall symptomatic of the state's antiquated tax system.
If the way to measure the success of Minnesota's recent "tax-the-rich" policy is the progressivity of the state income tax relative to other states, then the 2013 tax-law changes enacted by a DFL Legislature and Gov. Mark Dayton are a ringing triumph. An in-depth analysis conducted by the nonpartisan and highly regarded Minnesota Center for Fiscal Excellence (MCFE) shows how dramatic the impact of higher taxes has been on the state's wealthy.
For example, a Minnesota married couple with an income of $500,000 was paying state income taxes at a rate about 19 percent above the national average before the 2013 tax changes. Today, that same couple has a state income tax burden that is more than 40 percent above the national average.
Certainly, though, the gauge of a policy that puts Minnesota so far out of line with other states should be more than just whether it produces additional revenue for government to spend. The most important measures are whether the revenue is needed, collected fairly and used wisely. On those points, the policy of imposing new taxes on the wealthy is a mixed success.
By some measures, many Minnesotans are better off today than they were in pre-tax-the-rich days (to the extent such days ever existed in high-tax Minnesota). More people have access to health care, homelessness has been reduced (including, most significantly, among families with children) and more at-risk kids will receive the early education they need to improve the likelihood of school success. An improving economy has helped many Minnesotans, but the positive results of more government spending also can't be ignored.
Neither, though, can we ignore the cost of those gains. While the ideological debate between "tax the rich" and "no new taxes" will rage as long as there are Democrats and Republicans, the more important discussion is whether Minnesota can continue to be successful with its excessive reliance on individual income taxes — a dependency that has become much greater since 2013.
The state now gets about half of its operating revenue from individual income taxes, more than three times the national average. That is an unsustainable reliance on "the most unstable and unpredictable" source of revenue, as Dayton's own Department of Revenue stated in a 2013 briefing paper. The income tax produces a lot of revenue in good economic times — especially during bull stock markets — which falls precipitously during slowdowns.
Minnesota's aging demographics will add to the state's challenges not just on the spending side (huge new expenditures for health programs), but on the revenue side as well. As economists have pointed out, when more people move from their earning years to their retirement years, revenue from income taxes drops.
