Where to look for your property tax information
Your property tax bill or assessment notice is the fastest place to find what you owe. This document arrives by mail once or twice a year, depending on your county or municipality, and shows the assessed value of your property and the tax amount due. If you have received one recently, that is your current property tax figure.
If you cannot locate a bill, your county assessor's office holds the official record. You can contact them by phone, visit their office in person, or search their online database — most counties now post property records on a public website you can search by address or parcel number. The assessor's office is part of your county government, not a private company, and the information is public record.
Your mortgage lender also has this information. If you have a mortgage, your lender collects property taxes as part of your monthly escrow payment and can tell you the annual amount. This is useful if you need the figure quickly and your county's website is slow or offline.
Key Takeaways
- Your property tax bill arrives by mail from your county or municipality and shows exactly what you owe for the current tax year.
- Your county assessor's office maintains public records you can search online by address, and staff can provide the information by phone if you call during business hours.
- If you have a mortgage, your lender knows your annual property tax amount because they collect it in your escrow payment.
- The assessed value on your tax bill is not the same as your home's market value, and the two can differ significantly.
How to search your county assessor's online database
Most counties maintain a searchable property records database on their assessor's website. To use it, you will need your street address or your parcel number (a unique identifier assigned to your property). Start by going to your county government website and looking for a link labeled "Property Records," "Assessor Database," "GIS Map," or "Property Search."
Once you find the database, enter your address or parcel number. The system will return a record showing the assessed value, the tax rate for your area, and sometimes the annual tax amount. Some counties also display the property's square footage, lot size, and the year it was built. The exact layout and information available varies by county, but the assessed value and tax rate are standard.
If you cannot find the database online or your county does not have one, call the assessor's office directly. They can provide the information over the phone or mail you a copy of your property record. Most offices answer calls during standard business hours, Monday through Friday.
Understanding assessed value versus market value
The assessed value shown on your property tax record is not what your home is worth on the open market. Assessed value is the figure your county uses to calculate your property tax bill, and it is often lower than what you could sell your home for. In some states, assessed value is set at a percentage of market value — for example, 50 percent in one state or 100 percent in another. In other states, the assessor uses a formula based on recent sales of comparable homes in your area.
This distinction matters because your property tax bill is based on the assessed value, not the market value. If your home's market value has risen significantly but your assessed value has not been updated, you may be paying less tax than your neighbors with similar homes. Conversely, if your assessed value was set years ago and has not been adjusted downward, you may be paying more than you should.
You can find your home's estimated market value through real estate websites like Zillow or Redfin, which pull data from recent sales and listing prices. These estimates are not official, but they give you a sense of whether your assessed value is in the ballpark or significantly out of line.
What to do if you cannot find your property tax information
If you have searched your county's online database and cannot locate your property, try searching by parcel number instead of address. Parcel numbers are sometimes listed on your deed, mortgage documents, or utility bills. If you have none of these, call the assessor's office and provide your full street address and the owner's name — they can look it up and read the information to you over the phone.
If you recently purchased the property, the previous owner's tax bill may still be in the system under their name. The assessor's office can confirm whether the property has been transferred and provide you with the current owner's record. This process usually takes a few days.
For properties in areas that have not yet digitized their records, you may need to visit the assessor's office in person or request a certified copy of the property record by mail. Some offices charge a small fee for certified copies, typically between five and twenty dollars depending on the county.
How property tax is calculated from assessed value
Your property tax bill is calculated by multiplying your assessed value by the tax rate for your area. The tax rate is expressed as a percentage or as a dollar amount per thousand dollars of assessed value. For example, if your assessed value is $300,000 and your tax rate is 1.2 percent, your annual property tax would be $3,600. If the rate is expressed as $12 per $1,000 of assessed value, the calculation is the same: $300,000 divided by $1,000, multiplied by $12, equals $3,600.
Tax rates vary widely by location. A property worth the same amount in one county may have a much higher or lower tax bill in a neighboring county because the tax rates are different. This is why property tax is often a major factor in choosing where to buy a home.
Your county assessor's office or tax collector's office can explain how the rate is set and whether it has changed from the previous year. Some counties adjust rates annually based on the total value of all properties in the county and the amount of revenue needed to fund schools, roads, and other services.
When your property tax assessment changes
Your assessed value can change for several reasons. If you made major improvements to your home — such as adding a room, replacing the roof, or finishing a basement — the assessor may increase the assessed value. Some counties reassess all properties every few years, which can result in increases or decreases depending on the real estate market. In some states, assessed value is frozen until the property is sold, so your tax bill may not change for years.
You will receive notice if your assessed value changes. The notice usually arrives in the mail and explains the new value and the reason for the change. If you disagree with the new assessment, most counties allow you to file a formal challenge, often called an appeal or protest. The important date to file is usually 30 to 60 days from the date of the notice, so act quickly if you plan to challenge it.
To challenge an assessment, you typically need to show that the assessed value is higher than the market value or that the assessor made an error in calculating it. Gathering recent sales data for similar homes in your area, or getting an independent appraisal, can support your case. The assessor's office can explain the specific process and important date in your county.
Frequently Asked Questions
Is property tax the same as my mortgage payment?
No. If you have a mortgage, your lender collects property tax as part of your monthly payment and holds it in an escrow account, then pays the tax bill when it is due. Your mortgage payment itself covers the loan principal and interest. Property tax is a separate obligation to your county or municipality.
Can I find out what my neighbors pay in property tax?
Yes. Property tax records are public, and most county assessor websites display assessed values and sometimes tax amounts for all properties. You can search by address to see what your neighbors' properties are assessed at, though the actual tax bill depends on the tax rate for each property's location within the county.
What if I rent instead of own?
Renters do not pay property tax directly. The property owner pays it, and the cost is often factored into the rent. If you want to know the property tax on a rental home, you can search the county assessor's database using the address, just as you would for any other property.
How often does my property tax bill change?
This varies by state and county. Some counties send bills annually, others twice a year. The assessed value can change annually, every few years, or only when the property is sold, depending on your state's reassessment rules. Your tax bill will show the current year's amount and any changes from the previous year.
What if the assessed value seems too high?
Compare it to recent sales prices of similar homes in your area using real estate websites. If the assessed value is significantly higher than comparable homes sold recently, you may have grounds to challenge it. Contact your county assessor's office to ask about the appeal process and important date in your area.
