This study by Jenna Griffin, Jennifer Klippel, Kathryn Maguire, and Brendon Riggs analyzes the effects of changes in the Shared Revenue Program on Wisconsin taxpayers. The study covers the background, goals, and components of the program, as well as the analytical approach, results, and conclusions drawn. The impact of changes such as level-funding, per capita reductions, and discontinuation of formulas are discussed, along with measures of fiscal disparity and taxpayer equity. The study suggests alternatives for addressing disparities and emphasizes the importance of long-term consequences.

Changes in Shared Revenue and the Effects on Wisconsin Taxpayers Jenna Griffin, Jennifer Klippel, Kathryn Maguire, Brendon Riggs May 5, 2006
Overview • The Shared Revenue Program • Measures • Analytical Approach • Results • Conclusions
The Shared Revenue Program • Background • Goals • Property Tax Relief • Guaranteed Tax Base
Formula Components • Per-capita • Utilities • Aidable Revenues • Local purpose revenues • Tax base weight • Minimum Guarantee
The Issue • Changes to Shared Revenue • Level-Funding • Discontinuation of Formula • Per Capita Reductions • Circumstances • Medicaid • Truth in Sentencing • School Aid
Measures of Fiscal Disparity • Tax price: price to taxpayers, in mills, of a given level of expenditures • t/E ratio: tax price of $1,000 in per capita expenditures • low t/E ratio indicates a high level of fiscal well-being • Coefficient of variation: measures of disparity across time, using variation in t/E ratios for each year (standard deviation ÷ mean x 100) • high coefficient of variation (given as %) means high disparity • Taxpayer equity: municipalities with similar property tax rates should be able to afford similar expenditures, regardless of property wealth
Analytical Approach • Municipalities by 2000 EQV deciles • not population weighted • not counties and school districts • Milwaukee analyzed separately • Interaction with School Aid
2000-04 Cuts in Shared Revenue as Percent of Total Revenue Loss
Coefficient of Variation of Combined Municipal and School District Mill Rate
Alternatives • Return to Equalizing Formula • Revisiting Land-Use Assessment Policy • Reconfiguring the Current Expenditure Restraint Program • Diversifying Municipal Revenue Sources
Conclusion • Formula Decreased Disparities • Changes Increased Disparities • Long-term Consequences
