The property tax is the most widely unpopular tax in America. States have responded to this public opposition by enacting a range of tax relief policies, especially for homeowners (Cabral and Hoxby 2012). Among the most commonly adopted programs are homestead exemptions and property tax credits; all but three states have at least one of these programs. But despite their broad use and their potentially large impact on the distribution of property tax burdens, there has been remarkably little data available on the tax savings generated by property tax exemptions and credits.

Two new resources, available through the Lincoln Institute’s Significant Features of the Property Tax subcenter, begin to fill this need. These tables provide information for each state on the share of homeowners eligible for these programs and the level of tax savings they receive, as well as an analysis of how eligibility and benefits vary across the income distribution (see box 1, p. 26). This article draws on these resources to provide the first national study of property tax exemptions and credits with estimates of tax savings from these programs. With this information, policy makers have a critical tool to evaluate and improve the effectiveness of their property tax relief programs.

Box 1: State-by-State Details on Property Tax Exemptions and Credits

The Significant Features of the Property Tax sub-center provides three key resources with information on property tax exemptions and credits in all 50 states; it is accessible at www.lincolninst.edu/subcenters/significant-features-property-tax.

Tax Savings from Property Tax Exemptions and Credits

This online Excel file includes estimates of tax savings from programs in individual states (see abbreviated example below), plus overview tables that make it easy to compare across states. For each program, the file provides estimates of the number of eligible homeowners and the median benefit, as well as a distributional analysis by income quintile. This is the first time that detailed data are available for most of these programs.

Summary Table on Exemptions and Credits

This online Excel file includes a set of tables for 167 programs displaying the value of exemptions expressed in terms of market value; criteria related to age, disability, income, and veteran status; the type of taxes affected (i.e., school or county taxes); whether the tax loss is borne by state or local governments; local options; and more. The summary table makes it easy to conduct quantitative analysis of these programs or make quick state-by-state comparisons. The information in these tables was used to generate the tax savings estimates.

Residential Property Tax Relief

This section of the Significant Features website includes detailed descriptions of property tax exemptions and credits, which were used to create the online Summary Table on Exemptions and Credits. It also describes other types of property tax relief, such as circuit breakers and tax deferral programs.

Notes: Total tax savings from the Senior and Disabled Property Tax Homestead Exemption ($392M) is less than the combined total of the programs for Seniors ($378M) and the Disabled ($22M), because homeowners who are 65+ and disabled cannot claim the exemption twice. The online Summary Table shows that the Senior and Disabled Exemption is a $25,000 exemption for homeowners who are 65+ or disabled; the two Rollback programs are percentage exemptions of 2.5% and 10% for all owner-occupied residences.

How Property Tax Exemptions and Credits Work

Property tax relief programs come in a variety of forms. Homestead exemptions reduce the amount of property value subject to taxation, either by a fixed dollar amount or by a percentage of home value. Property tax credits, in contrast, directly reduce the homeowner’s tax bill by a fixed dollar amount or certain percentage.

As table 1 illustrates, programs designed to provide identical benefits to owners of $200,000 homes have widely different impacts on homeowners with higher- and lower-valued properties. Given a 1% tax rate, a $20,000 flat dollar exemption reduces property taxes for each homeowner by $200 ($20,000 x 1%). This program has a progressive impact on the property tax distribution because lower-income households tend to have less valuable homes, and the exemption represents a larger share of their home values. In this case, the $20,000 exemption reduces property taxes by 20% on the $100,000 home, 10% on the $200,000 home, and 5% on the $400,000 home.

A percentage exemption, in contrast, provides the same percentage reduction in taxes for all three homeowners—in this example, 10%. In dollar terms, however, percentage exemptions favor owners with higher-valued homes: a 10% across-the-board reduction lowers property taxes by only $100 on the $100,000 home but $400 on the $400,000 home.

In the case of flat dollar credits, homeowners with lower-valued homes usually receive the largest tax cuts in percentage terms. In contrast, the percentage tax credit again provides the owner of the $400,000 home the largest tax cut in dollar terms.

An important feature of property tax exemptions and percentage credits is that the dollar reduction (but not the percentage reduction) in taxes increases with tax rates. For instance, if the homes in table 1 were subject to a 2% tax rate, the dollar savings to their owners would double under the $20,000 exemption, 10% exemption, and 10% credit. While the dollar savings from flat dollar credits do not vary with tax rates, the percentage savings to homeowners decrease as tax rates rise.

Critical Features of Exemptions and Credits

The design of homestead exemption and property tax credit programs varies significantly across the 50 states. Figure 1 (p. 28) summarizes the number and share of state programs with the following key characteristics.

Benefit Calculation

Perhaps the most important feature of property tax relief programs is how benefits are calculated. In 2012, 59% of state programs provided flat dollar exemptions, 19% provided percentage exemptions, and the final fifth used property tax credits or other more complicated formulas to determine the amount of tax relief for each homeowner.

While the programs work in similar ways, their effects differ dramatically. As the examples in table 1 show, flat dollar exemptions and credits make the property tax distribution more progressive, while percentage exemptions and credits do not. As a result, to provide a certain level of tax relief for the median homeowner, percentage exemptions are more expensive than other programs because they result in larger property tax cuts for owners of higher-valued homes. Instead of changing the distribution of property taxes among homeowners, percentage exemptions are primarily a way to shift the tax burden away from homeowners as a group to businesses, renters, and owners of second homes.

State vs. Local Funding

The ultimate impact of exemptions and credits on property tax bills depends on how the programs are funded. Figure 1 shows that in 2012 only 28% of these programs included full state reimbursement to cover local revenue losses, while 57% had local governments bear revenue losses on their own. For 15% of programs, state and local governments shared the revenue loss in some way. (Broad-based programs for all homeowners or all seniors are more likely to receive state funding than programs for smaller groups such as veterans or the disabled. In 2012, 43% of tax relief programs for all homeowners or seniors were state-funded, 48% were locally-funded, and the rest split the revenue loss [Lincoln Institute of Land Policy 2014].)

The primary argument in favor of state funding of property tax exemptions and credits is that it can help mitigate disparities in property wealth across localities. Poorer communities and those without a significant business tax base typically have higher property tax rates, and these communities receive more funds per homeowner under state-funded programs. Without this assistance, communities with higher tax rates will experience larger revenue losses from tax relief programs unless they increase tax rates even further.

Seniors vs. All Age Groups

A number of states provide property tax relief for seniors. In 2012, more than a third favored seniors in some way: seven had statewide programs solely for this group, while 11 also covered younger homeowners but provided higher benefits for older homeowners. Other states provided either the same level of benefits for homeowners of all ages (15 states) or did not have broad-based programs (18 states).

Common arguments for targeting senior homeowners is that property taxes account for a larger share of their incomes, and local governments spend less on seniors than on younger homeowners with school-aged children. While it is true that property taxes account for a larger share of income for seniors than for working-age homeowners, the two groups devote nearly identical shares of their incomes to total housing costs because seniors are far less likely to have mortgages (Bowman et al. 2009, 11). In addition, property taxes are payments for public services, not user fees (Kenyon 2007, 36). Younger households without children in public schools do not benefit from property tax relief under these programs. The preferential tax treatment of seniors may simply reflect the fact that older households are a politically powerful group that votes in high numbers.

Estimating the Benefits of Exemptions and Credits

To estimate tax savings from homestead exemptions and property tax credits, the first step was to create the online Summary Table on Exemptions and Credits, which describes the key features of each program (see box 1 for description). These data draw almost entirely from the Residential Property Tax Relief Programs section of the Lincoln Institute’s Significant Features of the Property Tax database.

The second step was to combine this information with household-level data from the 2008–2012 American Community Survey (ACS). This nationally representative survey has data on more than 6.5 million U.S. households, including the household characteristics that determine program eligibility (age, income, disability, veteran status, etc.) and level of benefits received (home values and property tax bills). For a full explanation of the methodology used to estimate tax savings from exemptions and credits, see Langley (2015).

It is important to note that the estimates reported here are gross property tax savings. Tax relief programs often lead to higher property tax rates, especially under locally-funded programs where jurisdictions raise tax rates to offset the drop in the tax base from the exemptions. Estimates of net property tax savings would be lower in those communities, because the higher tax rates offset some of the direct tax relief provided from exemptions and credits.

Figure 2 shows that total property tax relief from homestead exemptions and property tax credits varies widely across states, but is generally small relative to total property tax revenues. In 14 of the 45 states with these programs, total savings are less than 0.5% of property tax revenues; in 27 states, the savings are less than 2.5%. At the same time, though, tax savings in nine states equal or exceed 10% of total property tax revenues. Indiana’s program is particularly generous, offering all homeowners a $45,000 exemption, then an additional 35% exemption for the first $600,000 in assessed value and a 25% exemption for value above $600,000.

Tax Savings for Different Types of Programs

Most states have more than one property tax exemption or credit program, with different programs targeting different groups of taxpayers—typically all homeowners, seniors, veterans, or the disabled. Figure 3 presents estimates on the share of homeowners eligible for these programs, along with the level of tax savings they receive.

Homeowners

Programs in 26 states are for nearly all homeowners, but usually limited to owner-occupied primary residences. In the typical state with these programs, the median homeowner receives a 12.5% cut in property taxes. On the high end, however, the median property tax cut was at least 25% in more than a quarter of states with these programs.

Seniors

Property tax relief programs in 18 states target older homeowners (typically at least age 65). These programs are much more generous than those covering all homeowners, with a median tax reduction of nearly 30% in the typical state. More than half of these programs provide a median tax cut of at least 25%, while only a sixth of them provide a median tax savings of less than 10%.

In the median state, 19.6% of homeowners are eligible for the programs, but eligibility rates vary greatly across states depending on whether there is an income ceiling. In the seven states that provide property tax relief to seniors regardless of income, 25–30% of homeowners are typically eligible. But in seven states with low income cutoffs ($10,000 to $30,000), only 5–10% of homeowners qualify. The other four states with property tax relief programs for seniors do not fit neatly into these two categories because they have higher income ceilings, strict wealth limits, or other eligibility criteria.

Veterans

State programs for veterans are more common than for any other group of homeowners, although eligibility is often limited to those who are disabled. Indeed, only 10 states provide property tax exemptions or credits for all veterans, even those without disabilities. In the median state with these programs, the typical beneficiary receives a property tax cut of just 3.2%.

There are 31 states that provide property tax exemptions or credits to veterans with service-connected disabilities. Because of the disability requirement, most veterans are ineligible for the programs. Indeed, only 15% of veterans qualify in the typical state. Overall, just 0.6% of homeowners are eligible for these programs in the median state.

Moreover, most of the 31 programs base eligibility and benefit levels on disability ratings from the Department of Veterans Affairs. Just seven states have programs for all partially disabled veterans, and veterans with lower disability ratings typically receive modest tax savings. On the other hand, 18 states restrict eligibility to veterans who are permanently and totally disabled. These programs benefit a very small share of veterans, but they usually provide a full 100% exemption.

Disabled

Programs in 23 states cover disabled homeowners, but really target two distinct groups: disabled homeowners and blind homeowners. In 2012, 12 states had programs for disabled homeowners, seven states had programs for the blind, and five states covered both groups. Programs for the disabled typically require beneficiaries to be permanently and totally disabled, but exact criteria vary. In the median state, 2.3% of homeowners are eligible for these programs and they receive a median property tax cut of 21%.

Conclusion

Homestead exemptions and property tax credits are an important part of the property tax system. These programs are used in nearly all states and can make the distribution of property taxes significantly more progressive. It is therefore critical that policymakers have good data on the property tax relief that these programs actually provide.

New research makes this information available for the first time. Using the Lincoln Institute’s Significant Features of the Property Tax subcenter, policymakers can easily compare key features of property tax exemption and credit programs across states, and see estimates of eligibility and tax savings. These data make it possible to evaluate the impacts of property tax exemptions and credits in their particular states as well as find ideas for program improvements.

Municipalities across the United States face social problems caused by high land prices and a shortage of affordable housing. Dick Netzer, professor emeritus of economics and public administration at the Wagner Graduate School of Public Service at New York University, discusses the role that land taxation might play in addressing these issues. Netzer is a long-time faculty associate of the Institute and is the editor of several Institute publications, including Land Value Taxation: Can It and Will It Work Today (1998).

Land Lines: Could a land tax affect the building portion of the housing supply?

Dick Netzer: Yes. This is a point on which it is useful to distinguish the effect of taxes on land, capital and labor. A change in the tax system that affects the return on an investment in any of these factors will affect the amount that is invested, because a higher rate of return will encourage more investment in that factor and increase its supply. Here, of course, land is an unusual factor of production, because for most purposes we can consider the supply of land as fixed. An increase in demand will not produce an increased supply of land, and reduced demand will not decrease the supply.

On the other hand, lower taxes on capital and labor will cause their supply to increase because of the increased net return to these factors. So a tax shift that reduces taxes on capital and labor and increases taxes on land will increase the supply of capital and labor but not reduce the supply of land. Building construction is a very capital-intensive industry, and an increased supply of capital and labor, reflecting their higher after-tax rewards, will allow more building construction to take place.

LL: How would a land tax affect the price of land?

DN: We can assume that the pre-tax prices reflect “what the market would bear,” and that imposition of a tax will not increase demand or raise the amount that buyers would be willing to pay for land. In that case, the total amount buyers will pay, including the new tax that they will face, will be unchanged. But the division of that payment will change. Less will go to the seller, and that will be balanced by the increased tax that will be paid to the government. We need to distinguish here between short-term and long-term effects. In the long term, the price does not change—it just is divided differently between the seller and the government. But the short-run outlay does change, because the tax is a periodic charge over time, while the price paid to the seller is a lump sum, or requires a mortgage and a down payment. Reducing the lump-sum component and increasing the periodic charge can ease liquidity problems, making land more accessible to purchasers who cannot readily raise large amounts of cash but who can meet their tax obligations.

LL: So the overall effect would be to help make housing more affordable?

DN: Yes. Together these effects on building supply and on land prices should result in lower rents and lower housing prices. Note that this is not a direct effect of increasing land taxes, but an indirect effect as a consequence of untaxing labor and capital.

LL: How do you analyze our current shortage of affordable housing?

DN: Since landowners are currently able to command an outsized return on their landholdings, tenants are paying higher rents than one would expect if the returns to land ownership were more modest. We are fortunate to live at a time when demand for housing is increasing—and so is demand for land on which to build new housing or to renovate existing housing. When demand rises for a product in fixed supply, prices generally rise as well. But this rising demand and these rising prices are not the result of actions by landowners themselves. So there is neither an economic need nor an equitable requirement that this increasing demand produce larger returns to landowners.

LL: What would the economic transition to higher land taxes look like?

DN: In a period when housing demand is rising, one solution would be to increase the tax on land values while reducing taxes on labor, machinery and other productive equipment. First, let’s consider the effect of untaxing labor and capital to some extent. A reduction in taxes on labor and machinery will allow people who offer their labor and savings to earn more after taxes. When these earnings increase, we would expect that more labor and savings will be offered, which in turn will cause some reduction in earnings, but not enough to drive the supply to its previous levels. Because the costs of construction and the cost of equipment will be lower, the prices that consumers pay for new housing will decline.

I don’t want to overstate the scale of this effect. If housing demand is very strong, the effects on prices are likely to be modest, but the supply of housing will increase. The net result will be to dampen increases in housing prices and rents.

LL: What about the effect of the transition on land prices themselves?

DN: That is the other part of the tax shift. Right after such a change in the tax system, the prices of land for new buyers will fall sharply, because along with the land they are buying an obligation to pay the new, higher land taxes. So homebuyers and renters, as well as homebuilders, will face lower immediate prices for land, offset by the higher taxes they will pay over time. Even with this offset, they will be in a better position than they were before the tax shift. There will be a significant lowering in the need for cash when homebuilding begins, when a home is purchased, and when rental property is sold to new investors. These are critical times for homebuyers and for investors in residential property, and a reduction in their cash requirements at these points can be a great benefit. Of course, they will have to pay the higher land taxes each year. But these taxes do not require an advance lump-sum payment, and they require no mortgage or construction loans. These positive liquidity effects can be very important in housing markets—perhaps not to the very largest commercial homebuilders or to the most affluent buyers, who may not require a mortgage at all, but very important to ordinary participants in the housing market.

LL: What about existing landowners who suddenly face higher taxes?

DN: This is a genuine issue, and there may well be negative liquidity effects for them. The sale value of their land will fall immediately and substantially. If so, they may be less willing or able to withhold their land from the market in hopes of gains from increases in market values in the future.

We can expect another impact on land taxes, in a different direction. The lower prices on labor and equipment will cause a greater investment in housing and other construction. That means there will be more demand for land, and this increased demand will raise land prices. However, this rise will be of a different character from the price increase that we considered at the beginning of this discussion, which represented an outsized return to landowners. Unlike speculative price increases that stem from expectations of even higher prices in the future, the rise in land values resulting from increased investment in labor and equipment will not outpace the increase in income generally. The knowledge that a large portion of the future gains will have to be paid to the government in the form of a high land value tax will prevent buyers from bidding up the price of land simply in expectation of those gains. This is a good example of the distinction between two types of price increases. The purely speculative increase produces outsized returns to current landowners but does not benefit society as a whole. A price increase that reflects greater availability of labor and capital can serve the function of allocating land among competing uses, which helps the economy function efficiently.
