To check your property tax, go to your county assessor or treasurer’s website and search by parcel number or street address. Nearly every county in the United States publishes a free, searchable database showing your current balance, assessed value, payment history, and upcoming due dates. If you’d rather not use the website, the same information is available by phone or in person at the county tax office, through your mortgage lender’s escrow disclosures, and on the notices the county mails you each year.
What to Have in Front of You Before You Search
Every county database asks for at least one identifier. The most reliable is your parcel number, sometimes called an Assessor’s Parcel Number or Property Identification Number. It’s a unique code the county assigns to your specific piece of land, and it prevents confusion when two properties share a similar address or sit on subdivided lots. You’ll find it on your property deed, last year’s assessment notice, or any prior tax bill.
No parcel number handy? Most search tools also accept a street address. Enter it exactly as it appears in county records, including the directional prefix (North, South, East, West) and any unit or apartment number. Small misspellings or abbreviation mismatches often return no results. Some portals also let you search by the owner’s name as it appears on the title, which helps when you’re checking on behalf of a family member or verifying a property before purchase.
Look It Up on the County Assessor or Treasurer Site
Start with the official website for your county assessor or county treasurer. These sites use .gov domain extensions and pull from the same records the county itself uses. Stick to those official portals rather than third-party lookup services, which repackage the same public data and often charge a fee for it.
Once you’re on the site, look for a link labeled something like “property search,” “tax bill lookup,” or “pay your taxes.” After you enter your parcel number or address, you’ll typically see:
- The property’s current assessed value.
- The tax rate applied to it.
- A breakdown showing which local taxing districts (school, city, fire, library) receive portions of your payment.
- Any outstanding balance.
- Payment history going back several years.
- Exemptions applied to the property.
- The date of the most recent appraisal.
This is the most complete snapshot of your property tax situation, and it updates in near real time as payments post.
When You Don’t Know the Parcel Number: GIS Parcel Maps
Many counties also offer a Geographic Information System viewer, an interactive map that lets you click on any parcel and pull up its tax and assessment data. These tools are especially useful when you don’t know your parcel number or when you’re researching a property you don’t yet own. Zoom into the neighborhood, click the parcel, and the map displays the owner’s name, property class, appraised values, and often a direct link to the tax account.
GIS viewers vary. Some show building footprints, lot dimensions, and flood zone overlays alongside the tax information. Others are more bare-bones but still let you navigate visually to the right parcel. On the assessor’s website, look for “GIS,” “parcel viewer,” or “property map.”
Check Through Your Mortgage Lender
If your mortgage includes an escrow account, your lender collects a portion of your estimated property taxes every month and pays the county on your behalf. You can monitor this through two disclosures your loan servicer is required to provide.
Your monthly mortgage statement must include a breakdown showing how much of your payment goes to principal, interest, and escrow.1Office of the Comptroller of the Currency. Truth in Lending Act Interagency Examination Procedures That escrow line reflects money set aside for taxes and insurance. Your servicer must also send an annual escrow account statement within 30 days of the end of the escrow computation year, recapping what was collected, what was paid out, and whether your account is on target.2Consumer Financial Protection Bureau. 12 CFR 1024.17 – Escrow Accounts
Compare the annual statement against the county’s records to confirm your lender paid the right amount. Discrepancies between what your lender says it paid and what the county shows as received can snowball into penalties if they go unaddressed.
If Your Escrow Account Falls Short
A property tax increase can create an escrow shortage, meaning your account balance has dropped below the target needed to cover the next payment. Your servicer identifies this during its annual analysis and will notify you of the gap.2Consumer Financial Protection Bureau. 12 CFR 1024.17 – Escrow Accounts The typical fix is a bump in your monthly payment to make up the difference over the next year. If the shortage is large, you may have the option to pay a lump sum instead.
Call or Visit the Tax Office
When the website is down, confusing, or simply not your preference, call or visit the county treasurer or tax collector’s office directly. That office maintains the official ledger of property tax accounts and handles payment processing. You can find contact information on the county’s main website or with a quick search for your county name and “tax collector.”
Staff can look up your account, confirm your balance, explain local rules about due dates and late fees, and walk you through any charges you don’t understand. Bring your parcel number or a copy of a prior tax bill if you’re visiting in person. Some offices will print a copy of your full tax history for a small administrative fee. This route is also the best option if you need to update a mailing address, report an ownership change, or ask about exemptions you might qualify for.
Mailed Notices and Tax Bills
Counties send two key documents by mail each year. The assessment notice comes first and tells you the value the assessor has placed on your property. This is the starting point for calculating what you’ll owe. The actual tax bill arrives later, once local taxing authorities have set their rates, and lists the final amount due along with payment deadlines.
Some jurisdictions mail one annual bill; others split it into two installments. If you haven’t received a notice by the time you normally expect it, contact the tax office right away. Not receiving a bill does not excuse you from the deadline or protect you from late penalties. The legal obligation to pay runs with the property, not with the mail carrier.
Reading What You See on the Screen
Knowing where to check your property tax is more useful when you can make sense of the numbers on screen. The basic formula is straightforward: your assessed value multiplied by the local tax rate equals your tax bill.
Assessed value isn’t always the same as market value. Many jurisdictions apply an assessment ratio, a percentage set by state law that converts the appraised market value into a smaller taxable figure. Ratios vary widely. Some states assess residential property at 100% of market value; others use 25% or 40%. If your home appraises at $300,000 and your state uses a 25% ratio, your assessed value is $75,000.
The tax rate is often expressed in mills. One mill equals $1 of tax for every $1,000 of assessed value. A 25-mill rate on a $75,000 assessed value produces a $1,875 tax bill. Your county portal will usually list the combined millage rate along with the individual rates for each taxing district, so you can see exactly how much goes to the school district versus the city versus the fire department.
Confirm Your Exemptions Are Applied
While you have the account open, check whether every exemption you qualify for is showing. The most common is the homestead exemption, which reduces the taxable value of a primary residence. Eligibility details differ by location, but the core requirements are consistent: you must own the property, occupy it as your main home, and in many places you must actively apply rather than receive the benefit automatically.
Beyond the homestead exemption, most jurisdictions offer additional reductions for specific groups. Senior citizen programs are often available at age 65 or older, sometimes with an income ceiling, and some freeze your assessed value so it doesn’t rise year over year. Disabled homeowner programs are comparable, typically requiring documentation of a qualifying disability. Veterans with a service-connected disability may qualify for reductions that range from partial to full elimination of property tax, depending on the disability rating and the jurisdiction.
Your county assessor’s website will list the exemptions available in your area and the application deadlines. If you already have an exemption, it should appear on the tax account page when you look up your property. If it’s missing, call the assessor’s office before the next billing cycle rather than waiting for it to correct itself.
