Property taxes explained in plain terms can save homeowners hundreds, sometimes thousands, of dollars each year. These taxes fund local schools, fire departments, roads, and public services. Yet many property owners pay their bills without understanding how the numbers are calculated or what options exist to reduce them.
This guide breaks down the core techniques for understanding property taxes. It covers how local governments calculate these taxes, the difference between assessed value and market value, and proven strategies to lower what homeowners owe. Anyone who receives a property tax bill should know these fundamentals.

ToggleKey Takeaways
- Property taxes are calculated by multiplying your assessed value by the local tax rate, so understanding both figures is essential for managing costs.
- Assessed value often differs from market value—many jurisdictions assess properties at only 50–80% of what they’d sell for.
- Claim all available exemptions (homestead, senior, veteran, disability) through your assessor’s office to legally reduce your tax bill.
- Review your property record card for errors like incorrect square footage or room counts that could inflate your assessment.
- Track comparable home sales in your area to identify if your assessed value is too high and build a case for appeal.
- File property tax appeals within the strict deadline (typically 30–90 days after receiving your notice) to preserve your right to challenge an unfair assessment.
How Property Taxes Are Calculated
Property taxes follow a straightforward formula: the assessed value of a property multiplied by the local tax rate (also called the mill rate). The result determines the annual property tax bill.
For example, if a home has an assessed value of $300,000 and the local tax rate is 1.5%, the owner pays $4,500 in property taxes that year.
Local governments set tax rates based on their budget needs. School districts, counties, municipalities, and special districts each may add their own rates. These rates combine to form the total property tax rate applied to each property.
Assessors, typically county officials, determine the assessed value. They evaluate properties periodically, often every one to three years. The assessment process considers factors like:
- Square footage and lot size
- Number of bedrooms and bathrooms
- Age and condition of the structure
- Recent sales of comparable properties nearby
- Improvements or renovations made to the property
Property taxes explained this way reveal why two similar homes in different neighborhoods can have very different tax bills. Location matters because tax rates vary between jurisdictions. A home worth $400,000 in one county might have a $6,000 tax bill while an identical home across the county line pays $8,000.
Some states cap how much assessed values can increase annually. California’s Proposition 13, for instance, limits assessment increases to 2% per year until a property sells. Other states reassess at full market value each cycle. These rules significantly impact long-term property tax costs.
Understanding Assessed Value Versus Market Value
Assessed value and market value are related but distinct concepts. Many homeowners confuse them, which leads to misunderstandings about their property tax bills.
Market value represents what a buyer would pay for a property in an open sale. Real estate agents, appraisers, and buyers determine this through comparable sales and market conditions.
Assessed value is the figure local tax authorities use to calculate property taxes. It may equal market value, but often it doesn’t. Many jurisdictions assess properties at a percentage of market value, sometimes 80%, 50%, or even lower.
Consider a home with a market value of $500,000. If the local assessment ratio is 60%, the assessed value becomes $300,000. Property taxes are then calculated on that $300,000 figure, not the full market value.
Property taxes explained through this lens help homeowners spot potential errors. If a home’s assessed value exceeds its market value, the owner is likely overpaying. This situation creates grounds for an appeal.
Homeowners should review their assessment notices carefully each year. These notices list the assessed value and often explain how it was determined. Comparing the assessed value to recent sales of similar homes reveals whether the assessment seems accurate.
Some states offer homestead exemptions that reduce the taxable portion of assessed value. A $50,000 homestead exemption on a $300,000 assessed value means property taxes apply only to $250,000. These exemptions typically require the owner to live in the property as a primary residence.
Techniques to Lower Your Property Tax Bill
Homeowners have several legitimate techniques to reduce their property tax burden. These strategies work within the legal framework while ensuring fair taxation.
Claim All Available Exemptions
Most states offer property tax exemptions that many homeowners overlook. Common exemptions include:
- Homestead exemptions for primary residences
- Senior citizen exemptions for homeowners over a certain age
- Veteran exemptions for those who served in the military
- Disability exemptions for qualified individuals
- Agricultural exemptions for working farmland
These exemptions don’t apply automatically. Homeowners must apply through their local assessor’s office. Missing an exemption means paying more than required.
Review Your Property Record Card
Assessors maintain records on every property. These records include details like square footage, number of rooms, lot size, and property features. Errors happen. A property record might list four bathrooms when only three exist, or include a finished basement that’s actually unfinished.
Homeowners can request their property record card from the assessor’s office. Checking this information against the actual property reveals mistakes that inflate assessed values.
Monitor Comparable Sales
Property taxes explained through comparables show why staying informed matters. If similar homes in the neighborhood sell for less than a property’s assessed value, the assessment may be too high.
Track recent sales within a half-mile radius. Note the sale prices, square footage, and condition of these homes. This data supports an appeal if the assessed value seems inflated.
Time Improvements Strategically
Major renovations increase property value, and property taxes. Homeowners who plan additions, pools, or extensive remodels should understand how these changes affect their tax bills. Some delay projects until after the assessment date to postpone the tax increase by a year.
How to Appeal Your Property Tax Assessment
Property owners who believe their assessment is too high can file an appeal. The process varies by state and county but follows a general pattern.
Gather Evidence First
Successful appeals rely on solid evidence. Before filing, homeowners should collect:
- Recent sales data for three to five comparable properties
- Photos showing any property damage or issues affecting value
- Professional appraisals (if available)
- The property record card with any identified errors
- Documentation of neighborhood factors that hurt values
The goal is proving the assessed value exceeds fair market value or contains factual errors.
File Within the Deadline
Every jurisdiction sets strict deadlines for assessment appeals. These deadlines typically fall 30 to 90 days after assessment notices arrive. Missing the deadline forfeits the right to appeal for that year.
Homeowners should mark their calendars when assessment notices arrive and act quickly.
Present the Case Clearly
Most initial appeals go to a local review board. Property taxes explained concisely and supported by evidence have the best chance of success. Stick to facts: comparable sales prices, square footage differences, condition issues, and record errors.
Boards review dozens of cases. Clear, organized presentations stand out. Bring copies of all evidence for board members.
Consider Further Appeals
If the local board denies an appeal, higher levels of review exist. State tax courts or tribunals hear cases that local boards reject. These formal proceedings may justify hiring a property tax attorney or professional consultant.
The cost of professional help makes sense when thousands of dollars in potential savings are at stake. Many consultants work on contingency, taking a percentage of the savings they achieve.
