State Policy Trends

Property Tax Reform 2020 – 2026

Since 2020, states have increasingly turned to exemptions, credits and other measures to reduce property tax burdens, even as counties rely on this revenue to fund essential services. This report examines the nationwide push for property tax relief and what state-level reforms can mean for county budgets, local services and fiscal autonomy.

Introduction

Since colonial times, property taxes have been a cornerstone of local government in America, funding the essential services that communities rely on every day, such as public safety, education, hospitals, emergency response, roads and bridges, parks, libraries and more.

Yet amid a national affordability crisis, state policymakers and residents have been increasingly pursuing property tax reform to ease homeowners' financial burdens. While these sweeping proposals may offer some financial relief, the public debate about property taxes often overlooks the potential implications of tax reductions for local services and how state-imposed restrictions can limit local governments’ flexibility to invest in community priorities.

This report examines the recent wave of state property tax reforms from the perspective of county governments. As administrative subdivisions of the state, counties are mandated by law to provide essential services to residents, yet state funding does not fully cover the costs of these responsibilities. Counties, therefore, rely on a mix of local taxes, fees and intergovernmental funding to support service delivery.

Property taxes are fundamentally local taxes, with approximately 3% of revenue going to states and the remainder supporting school districts, counties, townships, municipalities and special districts. Counties balance the need to keep our share of the property tax bill affordable with the responsibility to maintain quality services for residents, a challenge compounded by rising costs. In nearly every state, counties already face limitations on the types of taxes we can levy and the rates we can set.

The sections below examine state property tax reforms enacted since 2020, the factors driving increases in property tax bills and the essential services these revenues support. As vital partners in our nation's federalist system, counties need the authority and flexibility to raise and invest revenues in ways that reflect community priorities and meet our responsibilities mandated by law.

Key Takeaways

From January 2020 to June 2026, state legislatures enacted at least 168 property tax actions in 40 states and the District of Columbia.

Relief measures (exemptions, credits, refunds) were the most common target, making up 72% of property tax actions. Only four states passed legislation to impose a more restrictive rate or levy limit, and 10 states implemented changes to assessments – limiting how property is valued.  Together, these actions are calculated to cost state and local governments, including school districts, nearly $30 billion over the two fiscal years following passage.


At least 15 states have discussed property tax elimination within the past two years, with no legislation having yet passed.

In most of these states (nine), legislators have been driving the push, while in three states (Florida, North Dakota, and Texas), governors have been leading the discussion. Ohio, Michigan and South Dakota have all seen citizen-led movements to eliminate the property tax with a ballot measure.  


Property tax bills have increased significantly in recent years, but much of the nominal increase reflects inflation.

While the median property tax bill increased by 57% ($1,168) from 2010 to 2024, most was due to inflation and real property taxes only increased by 9% ($189), using 2010 dollars. Over the same period, the calculated effective tax rate actually declined by 18%. 


Property taxes are politically vulnerable, as they make up over one quarter (26%) of county government revenue but less than 2% of state general revenue and 0% of federal revenue.

In 2022, residents and businesses paid $140 billion more in state and local sales and gross receipts taxes and $111 billion more in state and local income taxes than in property taxes.


Property tax limitations do not happen in a vacuum but have wide-ranging implications.

Depending on how reforms are structured and funded, reductions in property tax revenue may increase reliance on other taxes or charges, require adjustments to key community services and/or limit local fiscal flexibility. Local government leaders need the authority and flexibility to determine which revenue structure best fits their community – whether driven by property taxes or other revenue sources.
 

A Brief History

A Brief History of Property Tax in the United States

Property taxes are among the oldest forms of taxation. Kings in feudal Europe legally owned all the land and used property to estimate the amount each person could pay to the crown as their “rent”: it was an attempt at taxation based on wealth and the ability to pay. Only later did the tax come to be regarded as a tax on property itself. The property tax came over to the American colonies early on, but after the Revolutionary War, leaders began debating how to enshrine the ideals of equality and democracy found in the Declaration of Independence in the taxation system. No longer were citizens paying “rent” to a king who owned all the land and “[imposed] Taxes on us without our Consent”;i rather, Americans were contributing to a collective society of which each individual was a member – a government “of the people, by the people, for the people.”ii

In the United States, the property tax functioned as the bedrock of revenue for local governments in the early colonies, through the time of westward expansion and into our modern economic system. Throughout the two and half centuries which followed the birth of our nation, states and local governments have been reforming the property tax system to try and better estimate the amount each person is able to contribute to key shared services which the government provides, often driven by these major economic shifts.iii

There is currently a new movement seeking to reform property taxes, which has its roots in a wave of “tax revolts” in the 1970s and 1980s. At that time, a combination of rising housing prices, high inflation, high unemployment and low economic growth made it more difficult for many homeowners to afford their property tax bills: they felt their property values no longer reflected the amount they could contribute to the community.iv State policymakers channeled this public resentment into sweeping property tax limitations in the form of rate limits, levy limits, assessment limits and more – many of which are still in effect today.v

State Legislation

State Legislation on Property Tax Reform 2020 - 2026

Property taxation is primarily governed by state and local laws, with states establishing the framework within which local governments exercise their taxing authority. The question of property taxes, therefore, is not a federal issue, but a state one. Nevertheless, there is a current movement against property taxes which is national in scope. From January 2020 to June 2026, state legislatures enacted at least 168 property tax actions in 40 states and the District of Columbia.vi These actions were not limited to any one specific region or political party but were widespread across a variety of states. States as politically different as Texas and Minnesota, or as geographically separate as Georgia and Oregon, all enacted legislation which would reduce property tax revenues and discretion for local governments.

State legislative actions were calculated to reduce local tax revenues by $15.3 billion in the fiscal year after passage, followed by another $14.5 billion in the next fiscal year.

These actions have substantial impacts on current and future budgets: in total, state legislative actions were calculated to reduce local tax revenues by $15.3 billion in the fiscal year after passage, followed by another $14.5 billion in the next fiscal year – not including the 34 ballot measures and six other bills which passed and do not have fiscal notes.vii

Many of these bills will have longer-lasting consequences, resulting in compounding revenue losses in subsequent years. Of this nearly $30 billion two-year fiscal impact, approximately 16% of this cost will fall directly and solely on local governments.viii Another 25% of the cost will be borne by state governments – meaning the state has committed to paying local governments back for lost property tax revenue, at least temporarily.ix The majority (58%) of the cost will be shared between state and local governments in some way.x It is important to note, however, that the costs borne entirely or in part by state governments may easily shift to local governments in the future, since property tax revenue is fundamentally the purview of local governments, and some state legislation provides reimbursements for lost revenue only for a certain period of time.xi

See endnote for more information on estimated fiscal impact.v

Since 2020, states have cut back property tax revenues using a variety of methods. Traditional property tax limits set a cap on the amount of revenue local governments can collect from property taxes, whether by fixing a maximum tax rate (rate limit), capping increases in total tax revenue (levy limit) or limiting increases in assessed property values for tax purposes (assessment limit). Some states also mandate that local governments apply their property tax rates to only a fraction of a property’s total assessed value (assessment ratio). As previously mentioned, many states have had limits like these set in place since the “tax revolts” of the 1970s and 1980s.xii Local governments tend to bear the costs of these traditional limits, and they are the norm across the U.S.xiii In fact, all states except five – Hawaii, Kansas, Minnesota, New Hampshire and Tennessee – set significant limits on counties’ ability to raise revenue through property taxes.xiv

Property tax reductions can also come in the form of relief measures, which reduce property tax bills for certain eligible groups of residents. Some relief measures reduce the assessed value of certain kinds of property by a fixed amount (exemptions), while others reduce tax bills more directly through credits or refunds – usually only for low-income residents. Many of these exemptions, credits or refunds tend to be funded by the state in part, at least temporarily. And some states will even pay local governments directly to help fund services while lowering property tax rates. But states can easily pass these costs to local governments when state budgets are tighter. While not every state imposes limitations, all provide at least some property tax relief, most often in the form of exemptions, tax credits, circuit breakers and deferrals.

The largest share (65) of the policy actions passed between 2020 and June 2026 created or modified a property tax exemption.

  • Exemption: An exemption lowers the taxable value of a property by a fixed dollar amount or percentage. Often, they are used to target specific property types, such as primary residences or farms, or to select populations, such as seniors, veterans or people with disabilities.
    • Effect: Lowers tax bills for certain residents but increases taxes for those not covered by the exemption. Fixed-dollar exemptions can make the property tax system more progressive, while still providing relief to all taxpayers. Typically applied only to homesteads (a homeowner's primary residence), so shifts the burden to businesses, second-home owners and renters.
    • Fiscal Burden: Varies – can be local, state or mixed.
  • Credit or Refund: An amount deducted from the final property tax bill, which either lowers the bill as a credit, or is paid and then later refunded. Often, but not always, tied to income-based requirements to provided targeted relief. Usually a fixed-dollar amount, but can also be a percentage of final tax bill, sometimes with a fixed-dollar cap.
    • Effect: Similar to exemptions, lowers tax bills for certain residents but increases taxes for those not covered by the credit or refund. Fixed-dollar credits or refunds can make the property tax system more progressive, especially if applied with income requirements. Typically applied only to lower-income homesteads, so shifts the burden to other non-eligible homesteads, businesses, second-home owners and renters.
    • Fiscal Burden: Varies – can be local, state or mixed.
  • Circuit Breaker: An upper limit on how much a household or individual pays based on income. Typically used for targeted tax relief for low-income residents.
    • Effect: Lowers tax bills for eligible lower-income households, with the state covering the remainder of the property tax bill. Adds a progressive element to the property tax system.
    • Fiscal Burden: State
  • Deferral: The option to delay the payment of taxes. Instead, a lien accrues in value against the property, allowing taxes to be collected when the property is sold or the estate is settled.
    • Effect: Provides relief to low- and fixed-income residents (especially, seniors) by decreasing property tax revenues in the short term.
    • Fiscal Burden: State or local

The current movement against property taxes is taking the form of relief measures which chip away at the tax base. Nearly three-quarters (72%) of the property tax actions passed from 2020 through June 2026 – 121 out of 168 – increased relief measures in some way. The largest share (65) created or modified a property tax exemption in 20 different states.

Wyoming and Texas are two prominent examples.

  • Wyoming created a 50 percent exemption (up to $3 million) for long-term homeowners 65 and older who have paid property taxes for 25 years or more (HB 3 and HB 45), as well as a 25 percent exemption on the first $1 million of market value for owner-occupied residential properties (SF 49).
  • Texas raised its general homestead exemption for school property taxes from $100,000 to $140,000 (SB 4) and increased its additional senior and disabled exemption from $10,000 to $60,000 (SB 23); these two increases alone are expected to reduce property tax revenues in Texas by $2 billion each year.

Sixteen pieces of legislation in 11 states (Arizona, Arkansas, Delaware, Georgia, Indiana, Maine, Maryland, Massachusetts, Missouri, Nebraska and North Dakota) implemented new or modified existing property tax credits.

  • Indiana enacted a piece of major property tax legislation which included a 10 percent property tax credit (up to $300) on all homesteaded properties in 2026, additional credits for seniors and disabled veterans, an increased exemption for business personal property and modified farmland assessment ratios (SEA 1).
  • Delaware increased the senior property tax credit from $400 to $500 per year (HB 250).
  • Arizona, Arkansas and North Dakota all expanded their homestead property tax credits (SB 1828, SB 263 and HB 1176, respectively). All of these property tax credits combined cost (or will cost) state and local governments nearly $3.3 billion in the first two years after passage.

Twenty-six state actions provided other kinds of direct or indirect property tax relief, whether in the form of direct payments to residents, circuit breakers, deferrals or supplemental aid to local governments. Twelve pieces of legislation across eight states (Colorado, Delaware, Georgia, Idaho, Illinois, Massachusetts, Montana and Utah) provided relief directly to homeowners, like the $30 million Veterans Property Tax Relief Reimbursement Program in Illinois (SB 1293) or the one-time property tax relief grant in Georgia (HB 18). Another 14 pieces of legislation in Minnesota and Wisconsin provided aid to local governments or special taxing districts to help relieve some pressure on property taxes as the demand for local services increases: for example, a $188-million school aid increase in Wisconsin (AB 68) or an $80-million county aid increase in Minnesota (HF 1938). In total, these other forms of relief are estimated to cost over $3.5 billion in the two years following their passage.

Over the past six years, four states (Colorado, Iowa, Ohio and North Dakota) and the District of Columbia passed legislation to impose a rate or levy limit or to make an existing one more restrictive.

  • In Iowa, counties have long been subject to a property tax rate limit of $3.50 per $1,000 of assessed value. Thirty counties used certain provisions to levy rates above this limit, until a 2023 law (HF 718) made this cap fully binding. Furthermore, a 2026 law (SF 2472) enacted a new 2 percent levy limit for Iowa counties, while leaving 3.5 mills as the rate limit in effect as a fixed ceiling.
  • North Dakota counties are now subject to a new 3 percent levy limit (HB 1176), which caps total property tax revenue collected by all local governments, irrespective of inflation (though not including new construction). This bill is a major change for a state where counties were previously subject only to a 60-mill rate limit. Not including what may compound in the future, the estimated two-year cost of all the rate and levy limit changes nationwide is nearly $2.6 billion.

Ten states implemented changes to property assessments (Alabama, Arizona, California, Colorado, Delaware, Louisiana, Minnesota, Montana, South Dakota and Wyoming), which alter the calculation of property values.

  • Alabama passed a new assessment limit of 7 percent for both residential and commercial properties (HB 73), though any change of ownership or major renovations would reset the property’s assessed value to market value.
  • Arizona reduced its assessment ratio for commercial property from 18 percent to 16 percent (SB 1093).
  • South Dakota introduced a new 3 percent limit on increases in aggregate assessed value of all owner-occupied, single-family homes in each county (SB 216) – a unique approach, since typical assessment limits cap growth for the value of individual homes. While not as impactful as the rate and levy limit changes, state actions related to assessment changes are estimated to cost counties at least $200 million annually.

Although nearly every state imposes limits on local property tax authority, and every state also provides property tax relief, policymakers and residents are increasingly expressing that these limits are enough. Since 2024, at least 15 states have discussed some form of property tax elimination, though none have passed any legislation to do so.xv Proposals to eliminate property taxes have included numerous options to replace the lost revenue.

  • A bill in Georgia proposed charging direct fees for local services (HR 1114 / HB 1116). Bills in Indiana and Kansas planned to fill in the funding gap by eliminating certain sales tax exemptions (HB 1288 and HCR 5014, respectively).
  • Nebraska, Oklahoma, South Dakota and Wyoming have all seen elimination proposals which include higher sales or consumption taxes.
  • North Dakota has begun paying down property taxes using a state fund generated from oil revenue and is considering increasing that amount until the state can effectively eliminate property taxes.

Since 2024, at least 15 states have discussed some form of property tax elimination, though none have passed any legislation to do so.

As research from the Tax Foundation demonstrates, any replacement revenue at the local level could result in widely different rates across counties to generate the same funding levels, while state-level replacement revenue would result in a politically challenging redistribution of funding, with losers effectively subsidizing the winners.xvi Not every state, however, has settled on a replacement revenue stream in their elimination proposals.

The Political Vulnerability of Property Taxes

There are a number of factors driving these state policy trends, with concerns about affordability at the top. From 2010 to 2024, median property tax bills increased by $1,168 (57%).xvii Most of that increase was due to inflation, yet on paper, residents only see that nearly $1,200 nominal increase, not the less than $200 real, inflation-adjusted increase.xviii Now, median per capita personal income increased during this time by 82% – more quickly than property tax bills.xix However, home prices doubled in this time period, and personal income did not increase equitably for everyone.xx Although the effective property tax rate declined by approximately 18% between 2010 and 2024, median property tax bills continued to increase, alongside broader increases in the cost of living and home values. Together, these trends help illustrate why residents remain concerned about housing affordability.xxi

Median Property Tax Bills Rose More Slowly Than Home Values, 2010–2024

Note: Data for 2020 was not released due to the COVID-19 pandemic. All series are indexed to 2010 = 100. The effective property tax rate is calculated as aggregate real estate taxes paid divided by aggregate owner-occupied home values; it does not represent statutory tax rates. Standard ACS 1-year estimates are unavailable for 2020.

Property taxes are politically vulnerable in part because of their visibility. Transparency is considered a good thing in government, but it can have its challenges for policymakers. Even though residents pay substantially more in state and local sales and income taxes than they do in property taxes ($140 billion and $111 billion more, respectively);xxii and even though state and local sales and income taxes have risen more quickly than property taxes (107% and 106% vs. 70%, respectively, from 2010 to 2024);xxiii homeowners know exactly what they pay in property taxes each year from the bill they receive, while sales and income taxes are paid incrementally in much smaller amounts. Very few residents understand the impact of a sales tax increase on their household budget, but any homeowner can immediately see the impact of a property tax increase. Furthermore, no state government relies on property tax revenue for its budget,xxiv placing cuts to property tax revenue squarely on the shoulders of county governments, public schools and other local entities which are already in a strained fiscal environment.

What Do Property Taxes Pay For?

Counties invest over $740 billion each year to provide crucial local services, with most funding going to health, public safety and education.

County leaders understand that rising property tax bills are a challenge for many residents and small businesses, and actively work to keep property tax rates as low as possible while still providing for the needs of local communities. But it is a balancing act. Counties invest over $740 billion each year to provide state-mandated local services, including roads, bridges, hospitals, courts, jails, public safety, 911 centers, education, utilities, parks, libraries, economic development and much more.xxv

Note: Adjustments were made to account for city-county consolidations and for states in which counties fund the public school system directly (rather than through separate school districts). Our analysis does not parse out any municipal funds which go directly to schools.

Over one quarter of this investment ($200 billion, or 26%) is only possible because of property taxes – the largest source of revenue for local services.xxvi And although counties usually collect all property taxes, the largest share of the revenue (41%) goes toward schools.xxvii As previously mentioned, states collect very little property tax revenue, and the federal government collects none: it is a specifically local source of revenue. As such, property taxes are invested locally to tangibly benefit those who pay them, that is, the homeowners and renters living nearby, with their direct input – more so than any state or federal taxes.

Even though residents tend to have a negative view of property taxes in the abstract,xxviii on the ground, community members tend to support property taxes and local control of them. In an analysis of 292 local ballot measures related to property taxes which were introduced from 2020 to 2025, 246 (84%) passed.xxix Most of these ballot measures were connected to specific services, such as schools, parks, physical or behavioral health services or libraries, because residents are often willing to pay more in taxes if they understand where the money will go. Furthermore, no state to date has had a property tax elimination ballot pass. As an example, North Dakota voters were directly asked in 2024 if they would like to eliminate property taxes and replace them, not with an additional sales or income tax levy, but with revenue from the state’s oil fund. This measure was voted down by a very large margin: 63-37.xxx

Cost of Government Services Rose Faster Than Cost of Living

After adjusting for population growth and the cost of government services, county property tax revenues increased by less than 1% annually, on average, between 2002 and 2022.xxxi These revenues have not increased exponentially in line with the housing market, but have simply kept pace with inflation and population growth and have consistently provided about three-fifths of all county tax revenue.xxxii In fact, the cost of providing government services has risen more quickly than the cost of living (49% vs. 44%, respectively, from 2010-2024), reflecting how fiscally strained local governments are, in addition to their residents.xxxiii

There may be a movement to curtail property tax bills, but on the ground, residents still expect and value high-quality services. Roads, bridges, 911 centers, parks, libraries, schools, police and fire protection, trash and recycling centers, clean water and many other local services are integral to the wellbeing of any community. If state lawmakers aim to reduce property tax revenues, they must consider alternatives. Property taxes are the number one source of revenue for counties – not to mention the most flexible under current laws – but they are not the only source of revenue.xxxiv Counties in every state utilize some combination of property taxes with other tax revenue, fees for services and intergovernmental transfers to provide services.xxxv For some county governments, this revenue structure is an intentional policy decision, while for many others, their revenue structure is imposed and limited by state statutes.

County Revenue Structure is Diverse

County-Generated Revenue Breakdown by State

Source: NACo Analysis of U.S. Census Bureau - 2022 Census of Individual Governments: Finance

Counties across the country have distinct needs and thus set our own property tax rates (within limits imposed by state statutes). From agricultural and manufacturing centers to communities reliant on natural resource development and tourism, and from growing communities with young families to those with aging populations, local priorities and service needs vary widely. Some communities may be willing to pay higher property taxes in exchange for higher levels of service, while other communities may be content with lower taxes and lower levels of service. Property taxes may work well as the top source of revenue in one county, while sales or income taxes may work better in a neighboring county. Residents should make these decisions at the local level with their local government, rather than be subject to a “one-size-fits-all” decision imposed by a higher level of government.

Conclusion

Local fiscal autonomy is a bedrock of our democratic system.

In many areas across the United States, county government is the level of government closest to the people, where individual voices can be heard most directly by elected leaders — whether at town hall meetings, through emails and phone calls or even at the grocery store or local park. Empowering county and municipal governments to make decisions about how to fund and deliver local services strengthens the voice of individual voters and reinforces the foundations of our nation's federalist system.

Yet, states increasingly impose mandates and shift responsibility for delivering essential services to counties while simultaneously restricting our authority to raise the revenue needed to fulfill those obligations. State-imposed property tax restrictions further constrain local discretion, leaving county leaders accountable for meeting community needs without the flexibility or resources to do so effectively. The consequences extend beyond local government budgets, undermining local accountability and weakening the ability of residents to shape the services and priorities of their own communities.

vi NACo analysis of National Conference of State Legislatures, “State Tax Actions Database,” (2020-2025); National Conference of State Legislatures, “State Ballot Measures Database,” (2020-2025); and additional sources from NACo’s own research. Unless otherwise noted, the remainder of the discussion in this section references information retrieved from these databases or NACo’s own research.

vii Note: Total costs were estimated by NCSL based on fiscal notes from state fiscal offices, when these were available. NACo research examined additional fiscal notes for bills missing from the database, when available. Ballot measures and some bills did not have publicly-available fiscal notes.

viii Note: Estimated breakdown of local vs. state fiscal impact was developed through NACo’s analysis of the 168 property tax actions. Some legislation explicitly mentions which level of government will bear the cost, adjusts a specifically state or specifically local levy, or includes partial or full state reimbursements. When this information is not explicitly available, we infer which level of government will bear the cost based on the type of limit or relief program. For example, the cost of a limit on increases to assessed value is typically borne by local governments unless a state reimbursement is specified. On the other hand, if the legislation increases a certain property tax credit which is already funded by the state, we can infer that the state will bear the increased cost. It is important to note, however, that some states may bear all or a portion of the cost only temporarily, so the fiscal costs of long-term property tax actions may increasingly shift to local governments in the future.

xvii Source: NACo analysis of U.S. Census Bureau, American Community Survey (ACS), 2010 and 2024 one-year estimates, and U.S. Bureau of Labor Statistics, Consumer Price Index for All Urban Consumers (CPI-U), annual averages. Median real estate taxes paid increased from $2,043 in 2010 to $3,211 in 2024, an increase of approximately 57% in nominal terms. After adjusting the 2024 amount for inflation using CPI-U, the increase was approximately $189, or 9%, expressed in constant 2010 dollars.

The estimated effective property tax rate is calculated by dividing aggregate real estate taxes paid by the aggregate value of owner-occupied housing units. This measure declined by approximately 18% between 2010 and 2024 and should not be interpreted as a statutory property tax rate.

xxii NACo Analysis of U.S. Census Bureau Annual Survey of State and Local Government Finances, 1977-2022 (compiled by the Urban Institute via State and Local Finance Data: Exploring the Census of Governments). Comparisons are based on combined state and local government tax collections in 2022. State and local sales and gross receipts taxes exceeded property tax collections by approximately $140 billion, while state and local individual and corporate income taxes exceeded property tax collections by approximately $111 billion. These comparisons reflect aggregate tax collections across state and local governments rather than taxes paid by a representative household.

xxvii Source: NACo analysis of U.S. Census Bureau, 2022 Census of Governments, Individual Unit Finance File. The distribution of property tax revenue by government type is based on NACo's adjusted analysis of Census of Governments data. To account for states in which county governments fund public education, a portion of county property tax revenue was reallocated to school districts, using education expenditures as a share of total county expenditures. Property tax revenue associated with consolidated city-county governments was also adjusted, with remaining revenue allocated equally between county and municipal governments after applicable education adjustments. The analysis excludes Connecticut, Rhode Island and the District of Columbia. These adjustments provide an estimated distribution of property tax revenue across government types and do not represent a direct allocation reported by the Census Bureau.

xxviii See AP-NORC Center for Public Affairs Research, “Majorities view local, state, and federal taxes as too high and delivering too little value for people like them” (January 2024). The survey shows residents have negative views not only of local property taxes, but of state sales taxes and the federal income tax.

xxix NACo analysis of Ballotpedia, “Local property tax ballot measures,” using only years 2020-2025. Note that this list is not comprehensive, and that Ballotpedia only includes local ballots within the 100 largest cities, within state capitals and throughout California and Virginia. Only 26 of the 292 ballot measures included increased a type of exemption, and only two measures proposed any decrease in property taxes. The large majority of these measures resulted in an increase or renewal of property taxes.
