Start with your county assessor's office
Your county assessor maintains the official record of every property in the county, including its assessed value, ownership history, and the tax amount owed. This is the primary source for property tax information. Most county assessor offices now publish searchable databases online where you can look up a property by address, parcel number, or owner name.
To find your county assessor's office, search "[your county name] assessor" plus your state. The office website typically has a link to the property search tool. You will need either the street address or the parcel number (a unique identifier assigned to each property). If you do not know the parcel number, the address alone usually works.
If the online database is not available or you cannot find what you need, you can visit the assessor's office in person or call during business hours. Staff can print out your property record, which shows the assessed value, land use classification, square footage, and the calculation used to arrive at the tax amount.
Key Takeaways
- Your county assessor's office maintains the official property record and publishes a searchable database on its website where you can look up assessed value and tax details by address.
- The parcel number (a unique property identifier) makes searching faster, but the street address alone usually works in the online database.
- Your property tax bill or mortgage statement shows the amount owed, but the assessor's record shows how that amount was calculated.
- If you disagree with the assessed value, most counties have a formal appeal process with a deadline that varies by state, usually 30 to 60 days after the assessment notice is mailed.
- Tax collector or treasurer offices handle payment and payment history, while the assessor handles valuation; both may have separate online portals.
Check your property tax bill or mortgage statement
If you own the property and have a mortgage, your lender sends you an annual property tax statement or includes the tax amount in your mortgage payment coupon. This document shows the total tax owed for the year and sometimes breaks down the amount by school district, county, and municipality.
The bill lists the parcel number, property address, and the tax amount due. It also shows the deadline for payment and the penalty for late payment. If you pay through escrow (your lender collects the tax as part of your monthly mortgage payment), the lender's annual statement will show how much was paid on your behalf.
If you rent the property, you will not receive a tax bill directly — the owner pays it. If you own the property outright with no mortgage, the county tax collector or treasurer mails the bill directly to you.
Use your county tax collector or treasurer's office
The tax collector (or treasurer, depending on your state) is the office that collects tax payments and maintains payment history. This is different from the assessor, who determines the value. The tax collector's office can tell you whether a payment was received, when it was received, and what the current balance is.
Most tax collector offices have online portals where you can view your account, see payment history, and sometimes set up automatic payments. Search "[your county name] tax collector" or "[your county name] treasurer" to find the office website and the payment portal.
If you need to know the exact amount owed or want to set up a payment plan because you are behind, the tax collector's office is the correct place to contact. They can also tell you whether a property is subject to a tax lien or foreclosure sale.
Access records through your state revenue or taxation department
Some states maintain a centralized database of property tax information that you can search without going to the county level. This is useful if you are looking up property in a county where the assessor's website is outdated or difficult to navigate.
Search "[your state name] property tax records" or "[your state name] revenue department" to find out whether your state offers this service. A few states charge a small fee for detailed records, but basic information is usually free. The state database may not be as current as the county assessor's records, so use it as a starting point and then confirm details with the county office.
Request records in person or by mail
If you cannot find the information online or need certified copies of property records, you can request them directly from the assessor's or tax collector's office. Most offices charge a small fee (typically $5 to $25) for copies and may take 5 to 10 business days to process the request.
Call the office to ask what documents you need to provide (usually just the property address or parcel number) and what the fee is. Some offices accept requests by mail, email, or through an online form on their website. If you need the records urgently, ask whether you can pick them up the same day or the next day.
Certified copies are necessary if you are using the records for a legal proceeding, a mortgage application, or a property dispute. For personal reference, an uncertified printout from the online database is usually sufficient.
Understand what each document shows
Property tax information comes in several forms, and each shows different details. The property assessment record (from the assessor) shows the assessed value, land use type, building square footage, lot size, and the formula used to calculate the tax. The property tax bill (from the tax collector) shows the amount owed, the due date, and payment instructions. The payment history (from the tax collector) shows when payments were made and in what amounts.
If you are researching a property you do not own, the assessor's record will show the current owner's name and mailing address. Some states restrict access to certain details (such as the owner's phone number or email), so you may not see all information online. The assessor's office can tell you what is public record and what is restricted.
What to do if you cannot find the information
If the county website is down or the search tool is not working, call the assessor's office directly. Most offices have staff available during business hours (usually 8 a.m. to 5 p.m. on weekdays) who can look up the information over the phone or direct you to an alternative source.
If you are looking up a property in a different state or county and do not know where to start, search the county name plus "assessor" or "property appraiser" (some southern states use "appraiser" instead of "assessor"). If that does not work, call the county clerk's office — they can direct you to the correct department.
If the property is very old or was recently transferred, the record may take several weeks to appear in the online database. The assessor's office can confirm whether the record exists and when it will be available online.
Frequently Asked Questions
Can I look up someone else's property tax information?
Yes. Property tax records are public record in all states, so you can look up any property by address. The assessor's online database will show the owner's name, assessed value, and tax amount. Some states restrict access to the owner's contact information, but the property details themselves are public.
What is the difference between assessed value and market value?
Assessed value is what the county assessor estimates the property is worth for tax purposes. Market value is what the property would sell for on the open market. Assessed value is usually lower than market value and is used to calculate the tax bill. The assessor updates assessed values periodically, but not every year in every state.
How do I find out when my property tax bill will arrive?
Contact your county tax collector's office or check their website for the tax bill mailing date. Most counties mail bills in the fall (September through November), but the timing varies by state. If you have a mortgage, your lender can also tell you when to expect the bill.
Can I see a breakdown of where my property tax money goes?
Yes. Your property tax bill usually shows how much goes to the school district, county government, municipality, and special districts (such as fire or water). The assessor's office can also provide this breakdown. The percentages vary by location and change year to year based on local budgets.
What if I think my property is assessed too high?
Most states allow you to file a formal appeal with the assessor or a county board of appeals within 30 to 60 days of receiving the assessment notice. The deadline and process vary by state. Contact your assessor's office to request the appeal form and deadline for your county.
