How Much Can Property Taxes Increase Per Year?

Property taxes serve as a primary funding source for essential local services, including public schools, road maintenance, and emergency services. These taxes are locally assessed and collected, based on the value of real estate within a jurisdiction. Understanding how these taxes are calculated, the factors that cause them to change, and the mechanisms that may limit their annual increase is important. This article explores property tax components, potential fluctuations, and state and local provisions designed to cap their growth.

Understanding Property Tax Calculation and Fluctuation

A property tax bill is determined by two main components: the property’s assessed value and the local tax rate. The assessed value is the valuation assigned to a property for tax purposes, which may not always equal its full market value. Assessors use mass appraisal techniques, considering factors like sales of similar homes, square footage, and property characteristics. This assessed value can change over time due to market conditions, property improvements, or periodic reassessments conducted by local authorities.

The second component is the tax rate, often referred to as the millage rate. This rate is set by local taxing authorities such as county, city, or school districts to meet their budgetary needs. A mill is equivalent to $1 of tax for every $1,000 of assessed property value. For example, a millage rate of 10 mills means $10 in tax for every $1,000 of assessed value.

Property tax bills can increase if either the assessed value of a property rises, the tax rate increases, or both. Local governments adjust tax rates based on their revenue requirements to fund public services. Both market dynamics influencing property values and local government fiscal decisions contribute to changes in a property owner’s tax obligation.

State and Local Limits on Property Tax Increases

Various state and local laws exist to limit the annual increase in property taxes, offering homeowners a degree of predictability. These limitations vary significantly by jurisdiction, aiming to protect property owners from sudden, substantial increases. These measures can come in several forms, including assessment caps, tax rate or levy limits, homestead exemptions, and circuit breaker programs.

Assessment caps directly limit how much a property’s assessed value can increase in a given year for tax purposes, regardless of its market value. Some jurisdictions might cap annual assessment increases to a specific percentage, such as 2% or 3%, or the rate of inflation, whichever is lower. Other approaches include capping increases at a higher percentage, for instance 10%, for primary residences, or allowing the assessed value to reset to market value only upon sale or significant improvement. These caps aim to prevent rapid market value appreciation from translating directly into proportionally high tax increases.

Tax rate or levy limits restrict the amount of revenue local governments can collect from property taxes. Some jurisdictions cap the millage rate itself, while others limit the total amount of property tax revenue a local government can collect annually, often to a percentage increase over the previous year, such as 1% or 2.5% plus new construction. These limits ensure that even if property values rise substantially, the overall tax burden collected by the taxing authority grows at a controlled pace. Voters may approve a “lid lift” to temporarily or permanently exceed these limits for specific needs.

Homestead exemptions reduce the taxable assessed value for primary residences, thereby lowering the tax bill. For example, a state might exempt the first $25,000 or $50,000 of a primary residence’s assessed value from property taxes. Eligibility for these exemptions depends on factors such as the property being a primary residence, homeowner’s age, disability status, or veteran status.

Circuit breaker programs provide property tax relief to eligible low- and moderate-income individuals and families when their property tax liability exceeds a certain percentage of their income. These programs function like an electrical circuit breaker, kicking in to provide a tax credit or refund when the tax burden becomes too high relative to income. While the specific design varies, many programs target seniors, disabled individuals, or those below a certain income threshold. This relief is provided after taxes are paid, often through a state-funded tax credit.

Managing Your Property Tax Assessment

Property owners can take steps to manage their property tax assessment and potentially reduce their tax burden. A first action involves reviewing the annual property tax assessment notice received from the local assessor’s office. This notice details the assessed value, any exemptions applied, and the deadline for appealing the assessment. It is important to check for factual errors in property characteristics listed, such as incorrect square footage, number of rooms, or property features.

If a property owner believes their assessment is inaccurate, they have grounds for an appeal. Common reasons for appealing include the assessed value being higher than the property’s actual market value, or the assessed value being inconsistent with comparable properties in the neighborhood. Discrepancies due to physical damage or deterioration not reflected in the assessment can also be valid reasons for an appeal.

The appeal process begins with an informal review or discussion with the assessor’s office to resolve discrepancies. If an agreement is not reached at this stage, a formal appeal can be filed with a local board or committee, often called a Board of Equalization and Review or Property Tax Assessment Board of Appeals. During a formal appeal, property owners should gather supporting documentation, such as recent comparable sales data, a professional appraisal, or photographs illustrating property conditions. Further appeals may be possible to a state board or even a court if the local decision is unsatisfactory.
