Far more common is the rollback penalty, a development deterrent that requires the landowner to pay the difference between property taxes actually paid during recent years of use value assessment and the taxes that would have been paid during those years with market-value assessment (plus accrued interest on that difference in some cases). Twenty-six states utilize this form of development penalty. Economic research has demonstrated that failure to levy a development penalty severely weakens the capacity of a UVA program to delay development of rural land at the edge of metropolitan regions (England and Mohr 2006).

The practice of use value assessment sometimes creates political tension within a community and can even damage the legitimacy of property taxation as a local revenue source. In November 2011, a Wisconsin TV station reported that owners of vacant lots in an upscale residential subdivision had harvested weeds from their parcels and successfully applied for agricultural assessment of their house lots pending construction. This allegation led at least one state representative to call for legislative hearings about abuses of the state's use value assessment program. According to Rep. Louis Molepske, "It should upset every Wisconsinite because they are being duped by those who… [want] to shift their property taxes to everybody else, unfairly" (Polcyn 2011).

Saving Family Farmers and Rural Landscapes
Have UVA programs "saved the family farmer" as some proponents had originally predicted? Not exactly. During the 1980s, the U.S. farm population fell dramatically by 31.2 percent. From 1991 to 2007, the number of small commercial farms continued its decline, from 1.08 million to 802,000. During that same time period, very large farms (with at least $1 million of gross cash income) increased their share of national farm production from nearly 28 percent to almost 47 percent (USDA Economic Research Service n.d.).

If preferential assessment of rural land has not prevented the decline of family farming, has it slowed the rate of land development in rural America? The evidence on this question is positive, but modestly so. A study of land use change in New Jersey from its adoption of use value assessment in 1964 to 1990 found that the program had a very modest impact on the rate of conversion of agricultural land to urban uses (Parks and Quimio 1996). After her 1998 study of nearly 3,000 counties across the U.S., Morris (1998) concluded that, on average, UVA programs resulted in roughly 10 percent more of the land in a county being retained in farming after 20 years of program operation. After their detailed study of land use changes in Louisiana, Polyakov and Zhang (2008) concluded that an additional 162,000 acres of farmland would have been developed during the five years after 1992 if there had been no UVA program in the state. It seems, then, that UVA programs have slowed down metropolitan sprawl somewhat during recent decades.

Shifting the Tax Burden to One's Neighbors
Although slowing the rate of land development is an environmental and public benefit of UVA programs, it entails a social cost. When the properties of farmers, ranchers, and forest owners are assessed far below market value, local governments collect fewer property tax receipts unless they raise the tax rate that is levied on all taxable properties. If they raise their property tax rates to maintain public expenditure levels, rural towns and counties increase the tax bills of non-UVA owners, primarily homeowners.

This potentially regressive impact of UVA programs has been known for decades. In its 1976 report on preferential assessment of farms and open space, the President's Council on Environmental Quality (1976, 6–8) stated clearly that these state programs result in tax expenditures of significant magnitude that redistribute income among taxpayers:

"All differential assessment laws . . . [entail] 'tax expenditures,' by means of which the tax bills of some taxpayers are reduced. . . . In most cases, the cost of this reduction is spread over all the other taxpayers. . . . The effect of a tax expenditure is precisely the same as if the taxpayers who receive the benefit were to pay taxes at the same rate as other, non-preferred taxpayers, and then were to receive a simultaneous grant . . . in the amount of the tax benefit."

The magnitude of this tax shift among property owners can be quite substantial. Anderson and Griffing (2000) report estimates of the tax expenditures in two Nebraska counties associated with the state's UVA program. The average tax expenditure is approximately 36 percent of revenue in Lancaster County and 75 percent of revenue in Sarpy County.
