Start with your county assessor's office
Your county assessor keeps the official record of every property in the county, including its assessed value, the owner's name, and the tax amount owed. This is the single most reliable source for property tax information. Most county assessor offices now have searchable online databases where you can look up a property by address or parcel number and see the assessed value, recent tax bills, and sometimes payment history.
If the online database is not available or you cannot find what you need, call the assessor's office directly or visit in person. The phone number and address are listed on your county's official website — search "[your county name] assessor" to find it. Staff can tell you the current assessed value, explain how it was calculated, and point you to tax bills or appeals records if you need them.
Some assessor offices charge a small fee to print or mail records, but online access is almost always free. Bring or provide the property address and the owner's name if you have them, though the address alone is usually enough.
Key Takeaways
- Your county assessor's office maintains the official property tax record and usually offers a free online search by address or parcel number.
- The tax collector or treasurer's office handles payment and can show you what is owed, what has been paid, and payment due dates.
- Your property tax bill arrives by mail once or twice a year and lists the assessed value, tax rate, and amount due.
- If you own the property, the deed is filed with the county clerk or recorder and shows ownership history and any liens against the property.
- Online county portals vary widely — some are searchable by address, others require a parcel number, and some require you to create an account.
Check your property tax bill
If you own the property, you receive a tax bill by mail, usually once or twice per year depending on your county. This bill is the fastest way to see what you owe, when it is due, and the breakdown of the assessed value and tax rate. Keep bills from recent years so you can track changes in the assessed value and compare year to year.
The bill shows the parcel number, which is a unique identifier for the property. Write this number down — it makes searching county databases much faster and more accurate than using the address alone. If you have lost a bill or need a copy, the tax collector's office (sometimes called the treasurer's office) can mail or email it to you.
Use your county tax collector or treasurer's office
The tax collector or treasurer handles payment and maintains records of what has been paid and what remains owed. This office is separate from the assessor — the assessor sets the value, and the collector manages the money. Call or visit the collector's office to ask about payment history, current balance, or payment plans if you are behind.
Many counties now offer online payment portals where you can see your account balance, view past bills, and set up automatic payments. Search "[your county name] tax collector" or "[your county name] treasurer" to find the office website and portal. Some portals require you to create an account using your parcel number or property address.
Search the county clerk or recorder's office for deed and ownership records
The county clerk or recorder (the title varies by state) keeps the deed to the property, which shows who owns it and any liens or mortgages against it. This is different from tax information but is often needed to understand the full picture of a property. Most county clerk offices have searchable online databases of recorded documents, including deeds, mortgages, and tax liens.
Search by property address or owner name to find the deed and see the chain of ownership. If a property tax lien has been filed because taxes were not paid, it will show up in the recorder's database as well. This record is public and free to search online in most counties.
Access parcel maps and property details through GIS systems
Many counties maintain a Geographic Information System (GIS) that shows property boundaries, lot size, building footprints, and sometimes photos of the structure. These systems are free and searchable by address. The map view can help you confirm you are looking at the right property and see details like square footage or number of buildings on the lot.
Search "[your county name] GIS" or "[your county name] property appraiser" to find the system. Some counties call it the property appraiser's office instead of the assessor's office, but the function is the same. The GIS often links to the assessor's database, so you can move between the map view and the tax record in one place.
Request records by mail or in person if online access is limited
Not all counties have fully searchable online databases. If the county website does not have what you need, you can request records by mail, email, or in person. Call the assessor's or tax collector's office and ask what documents they can provide and whether there is a fee. Most counties charge between $5 and $25 for copies of tax bills, deeds, or assessment records.
Provide the property address and owner name, and ask for the most recent tax bill, the current assessed value, and payment history. Requests by mail usually take one to three weeks. If you need the information faster, visiting in person is usually the quickest option, and staff can often answer questions on the spot.
Understand what information you will find
Property tax records show the assessed value (what the county says the property is worth for tax purposes), the tax rate (set by your local government), and the amount owed. They do not show the market value or sale price of the property — the assessed value is often lower than what the property would sell for. Records also show whether taxes are current or overdue, and sometimes show payment history going back several years.
Deed and ownership records show who legally owns the property and any mortgages or liens filed against it. A tax lien means the county has a legal claim on the property because property taxes were not paid. This information is public and can be viewed by anyone, not just the owner.
Frequently Asked Questions
How do I find my parcel number?
Your parcel number appears on your property tax bill. If you do not have a recent bill, call the county assessor's or tax collector's office with your address and they will give it to you. The parcel number is usually printed in the upper corner or header of the bill.
Can I look up someone else's property tax information?
Yes. Property tax records are public. You can search by address or owner name in the county assessor's or tax collector's online database. Deed and ownership records are also public and searchable through the county clerk or recorder's office.
What if my county does not have an online database?
Call the assessor's or tax collector's office directly and ask how to request records. They can mail or email copies of tax bills and assessment information, usually for a small fee. Some smaller counties still maintain records on paper only, but staff can pull them for you by phone or mail request.
How often is property tax information updated?
The assessed value is usually updated once per year, though the timing varies by county. Tax bills are issued once or twice per year depending on your county's schedule. Payment records update as soon as a payment is processed, which is usually within a few business days.
What does it mean if there is a tax lien on the property?
A tax lien means property taxes were not paid and the county has filed a legal claim against the property. The lien appears in the county recorder's database and gives the county the right to sell the property to recover the unpaid taxes. If you see a lien, contact the tax collector's office immediately to discuss payment options or payment plans.
