Minnesota state and local roads generate 52 billion vehicle miles of travel (VMT) annually at a cost of $2.6 billion. Spending averages 5 cents per VMT statewide, but travel on local government roads, especially low volume networks, costs more. State road aid reduces the local tax effort significantly in most high cost areas. State and local road funding is supported primarily with motor fuels excise taxes, vehicle registration and sales taxes, local property taxes, and state property tax relief. The average Minnesota household pays about $600 annually for roads, but this estimate varies widely with household characteristics. Substituting travel-dependent taxes for fixed or hidden charges could improve the tax system efficiency, and potentially distribute the road tax burden more fairly. Compared to current law, even radical tax reform may not change the road tax bill for some households.
Local governments in the U.S. use a variety of tax mechanisms to fund local roads. Twelve options are examined in this report related to property access, vehicle use or local economic activity. The most frequent local levies are property taxes, special assessments, vehicle registration taxes, motor fuel taxes and local sales taxes. The overall mix of local road funding also varies widely by state and region. Nebraska, Wisconsin and Kansas have local road revenues most like Minnesota, while local roads funding in New Hampshire, Florida and Nevada is the least similar. The benefits of any individual road tax must be judged in the context of the larger state and local tax system.
The future adequacy of Minnesota road funding is evaluated in a 27-year forecast of current law road taxes (motor vehicle registration tax, motor vehicle sales tax, and motor fuels excise tax). Revenue projections are compared with inflation-adjusted base costs in three economic growth scenarios (Trend, Optimistic, and Pessimistic), using two price deflators (core-CPI and state/local government costs). The Trend scenario predicts road tax revenues will lose purchasing power to inflation by 2020, but over the forecast period cumulative revenues and costs nearly balance out. According to this scenario, current tax policy can support 2003 service levels into the future, but not fund system improvements. The Optimistic scenario forecasts a surplus in purchasing power in all 27 years, providing the opportunity for significant new spending without changing current law. Under the Pessimistic scenario, tax revenues fall short of inflationary costs by 2012, with the annual loss in purchasing power reaching $1 billion by 2030. In this scenario, road tax policy changes are needed to avert significant declines in road service.
This report examines the changes in city and county spending observed between 1993 and 2003 to determine whether there have been any major changes in the trend toward government spending.
