To find out the taxes on a property by address, go to the county assessor’s or treasurer’s website for the county where the property sits, open the property search tool, and enter the street address. The record that comes back will show the assessed value, the tax rate applied, any exemptions, and the current amount owed. It is public information, it is free, and it usually takes a few minutes.
Start With the County Website
Most counties publish property tax data through the assessor’s or treasurer’s office. On the official county site, look for a tab labeled “Property Search,” “Tax Records,” or “Parcel Lookup.” Enter the address, choose the matching record from the results, and the system will display the current assessed value, the tax amount, any exemptions, and the payment status. Many portals also show several years of history so you can see how the assessment has changed.
If a single address returns several results, that usually means the building has multiple units or the parcel has been subdivided. Adding the owner’s full legal name narrows the list. For a single exact record, search by the Assessor’s Parcel Number instead (see below).
What You Need Before You Search
A standard street address is enough in most cases. Two other identifiers help when the address does not.
The Assessor’s Parcel Number (APN, sometimes called a PIN) is a unique string of digits assigned to each piece of real estate by the local taxing authority. Every county assessor uses this number to track a property’s value and ownership history, and searching by APN returns a single, exact record. You can find the APN on a prior tax bill, a recorded deed, or the county assessor’s website.
In rural or undeveloped areas without a standard street address, properties are identified by a legal description based on Section, Township, and Range coordinates from the Public Land Survey System. You do not need to understand the grid yourself. Copy the legal description from the deed and paste it into the county search tool.
Assessor Versus Treasurer: Which Office Has What
Two local offices split the work, and knowing which is which saves time.
The county assessor determines the value of every property in the county for tax purposes. The assessor does not set tax rates, issue bills, or collect payments.
The county treasurer (or tax collector) generates the bills and processes payments. In some cities, a municipal tax office handles these functions independently of the county.
If you want the assessed value and property characteristics, start with the assessor. If you want the actual bill and whether it has been paid, start with the treasurer. Many counties link the two records together in a single search interface, so one lookup shows both.
One note for homeowners: if your lender collects property taxes through an escrow account, your servicer pays the bill on your behalf from that account each year. The underlying tax record is still maintained by the county and you can look it up directly at any time.
Other Ways to Look Up Property Taxes
Real Estate Sites
Zillow, Realtor.com, and Redfin display property tax estimates on their listing pages. These figures are pulled from public records and can give you a quick ballpark, but they may lag behind the county’s records by months. For an accurate, current figure, go directly to the county portal. Third-party tools are most useful as a starting point when you do not yet know which county to search.
In Person or by Mail
If the online system is unavailable, you can visit the assessor’s or treasurer’s office during business hours and request records at the counter. Mail-in requests are also accepted, though they typically require a written application and a small administrative fee. Government fees for issuing certified property tax documents vary widely, from under $10 in some areas to $75 or more elsewhere for a certified tax status report. Some offices also require a stamped, self-addressed return envelope.
How to Read the Record You Pulled Up
A property tax record packs several figures onto one page. Knowing what each one means is the difference between looking at numbers and understanding the bill.
- Market value. The assessor’s estimate of what the property would sell for in an open-market transaction. This is the starting point for the tax calculation.
- Assessed value. The portion of market value subject to taxation. Many jurisdictions apply an assessment ratio, taxing only a percentage of market value, so the assessed value is often lower than the market value.
- Exemptions. Reductions applied to the assessed value before the tax rate is calculated. A homestead exemption subtracts a fixed dollar amount from the taxable value of a primary residence. Other common exemptions target seniors, disabled veterans, and people with low incomes. Any exemptions on the property appear as line items reducing the taxable figure.
- Mill rate (or tax rate). The rate used to calculate the tax. One mill equals one dollar of tax for every $1,000 of taxable value. Some jurisdictions express this as a percentage instead. A rate of 20 mills is the same as 2%.
- Special assessments. Separate charges for local improvements like street lighting, sidewalks, or sewer upgrades. These appear as individual line items added on top of the base property tax.
- Payment status. Whether the current taxes are paid in full, partially paid, or delinquent. Unpaid amounts and any penalties or interest also appear here.
Doing the Math
The basic formula: divide the mill rate by 1,000, then multiply by the property’s taxable value (assessed value minus any exemptions). If a home’s taxable value is $200,000 and the local mill rate is 20, the annual property tax is 0.020 × $200,000 = $4,000.
One property usually has more than one taxing authority applying its own rate. The county, school district, city, and any special districts can each levy separately, and the tax bill adds them all together plus any special assessments. The total effective rate on a home varies significantly by location. The national average hovers below 1% of a home’s market value, while some areas exceed 2%.
Reading the Payment Status
The payment section of the record tells you whether the taxes on the property are current. Payment schedules themselves vary by jurisdiction: some counties bill annually with a single due date, others split the year into two or four installments, and semiannual billing is the most common structure, with payments typically due in the spring and fall. The tax bill or county treasurer’s website lists the exact dates for that area.
If the record shows a balance due, expect penalties and interest layered on top of it. Most jurisdictions impose a flat penalty (often around 10% of the overdue amount) shortly after the due date, then begin charging monthly interest on the unpaid balance. Annual interest rates on delinquent property taxes range from roughly 5% to 18% depending on the jurisdiction. These charges continue accruing until the balance is paid.
A long-unpaid balance can produce a tax lien, a legal claim by the local government that takes priority over most other debts, including mortgages. Under federal law, a tax lien attaches to all property belonging to the person who owes the tax once demand has been made and payment is refused.1Office of the Law Revision Counsel. 26 USC 6321 – Lien for Taxes State and local property tax liens generally take priority even over a previously recorded federal tax lien.2Office of the Law Revision Counsel. 26 USC 6323 – Validity and Priority Against Certain Persons In some states, the government sells the lien itself to an investor, who pays off the delinquent amount and then collects repayment plus interest from the owner. In other states, the government auctions the property directly through a tax deed sale after a waiting period. If you are looking up a property because you are considering buying it, a delinquent payment status is worth taking seriously before you go further.
A Note on Exemptions Not Yet on the Record
If you are looking up your own property and expected an exemption to appear but it does not, that usually means it was never applied for. Most states require you to apply for exemptions such as the homestead, senior, or disabled veteran exemption, and missing the application window means paying the full amount until the next cycle. The county assessor’s office can tell you which exemptions are available in your area, the forms, and the filing deadlines.
