Start with your county assessor or tax collector

Property tax information lives in two places: your county assessor's office holds the property record and value, and your county tax collector or treasurer holds the bill and payment history. Most counties now post both online, searchable by address or parcel number. You do not need to visit in person — a county website search takes minutes.

To find the right office, search "[your county name] assessor" or "[your county name] property tax" in a search engine. The assessor's site usually has a "property search" or "property records" tool. The tax collector's site typically has a "tax bill lookup" or "payment history" section. Both will ask for your address or parcel number, which you can find on an old tax bill, a mortgage statement, or a deed.

If your county does not have online access, call the assessor's office directly. They can mail you a property record card or read the information over the phone. Some counties charge a small fee for mailed copies; phone calls are free.

Key Takeaways

  • Your county assessor's website holds the property record, assessed value, and ownership history; your tax collector's site holds the bill amount and payment dates.
  • Search by address or parcel number on the county website — no login or fee required for basic information.
  • If online records are not available, the assessor's office will provide information by phone or mail.
  • Your mortgage lender or title company can also provide a copy of the property record if you cannot locate the county website.
  • Property tax bills are public record in all states, so anyone can look up what your taxes are.

What the assessor's record shows you

The assessor's property record lists the assessed value (the value the county uses to calculate your tax bill), the land value and building value separately, the square footage, lot size, year built, number of bedrooms and bathrooms, and recent sales history. It also shows whether the property is classified as residential, commercial, or agricultural — this classification affects your tax rate.

The record may also note exemptions you hold, such as a homestead exemption, agricultural exemption, or disability exemption. If you think you may have access to for an exemption but it is not listed, the assessor's office is where you file the paperwork. The record is updated annually, usually after a reassessment or after you report a change in use.

What the tax collector's bill shows you

The tax bill breaks down the total amount owed: the assessed value, the tax rate (often shown as a millage rate or per-$1,000 amount), the calculated tax, and any special assessments or fees. It shows the due date, the payment address, and accepted payment methods. Most bills also show the payment history for the current year and sometimes prior years.

The bill tells you whether taxes are paid in full by a single date or in installments. Some counties split the bill into two or four payments throughout the year. The bill also notes if you are behind on payments or if a lien has been filed against the property.

How to find your parcel number if you do not have a bill

Your parcel number is a unique identifier assigned by the county. It appears on tax bills, property deeds, and mortgage statements. If you do not have any of those documents, you can find it by searching the assessor's website with your street address alone — most systems return results by address and show the parcel number in the results.

You can also call the assessor's office and give them your street address; they will read the parcel number to you over the phone. Some counties print the parcel number on utility bills as well, so check a recent electric or water bill.

Accessing records if you do not own the property

Property tax records are public in all states. You can look up anyone's property information, tax bill, and assessed value without their permission. This is useful if you are buying a home and want to see what the current owner pays in taxes, or if you are researching a neighborhood.

Search the county assessor's or tax collector's website by the street address. No login is required. Some counties charge a fee to request a certified copy of a record by mail, but viewing online is always free.

What to do if you find an error on your record

If the assessed value seems too high, the square footage is wrong, or a property feature is listed incorrectly, contact the assessor's office. They can explain how the value was calculated and may allow you to file a formal challenge called an appeal or protest. The important date to file varies by state — some allow appeals year-round, others have a narrow window after the assessment is mailed.

Bring documentation of the error: a recent appraisal, photos, a contractor's estimate, or a deed showing different property details. The assessor will review your evidence and may adjust the record. If you disagree with their decision, most states allow a second appeal to a county board or to tax court, though this usually requires a fee and sometimes a lawyer.

Using third-party property sites

Websites like Zillow, Redfin, and Trulia display property tax information pulled from county records. These sites are free to use and often easier to navigate than county websites, but the information is not always current — some sites update quarterly or annually rather than in real time. The official county assessor or tax collector website is always the most up-to-date source.

Third-party sites are useful for comparing taxes across neighborhoods or seeing historical tax trends, but if you need the exact current bill amount or payment status, go directly to the county. County websites also show details that third-party sites omit, such as exemptions, special assessments, and payment history.

Frequently Asked Questions

Can I see someone else's property tax bill?

Yes. Property tax records are public in all states. You can search any address on the county assessor's or tax collector's website and see the assessed value, tax amount, and payment history. No permission is required.

What if my county does not have an online search tool?

Call the assessor's office or tax collector's office directly. They will provide the information by phone or mail. Some counties charge a small fee for mailed copies, but phone lookups are free. Ask for the property record card or a copy of the current tax bill.

How often is property tax information updated?

Assessed values are updated annually, usually in the spring or fall depending on your county. Tax bills are updated as payments are made and posted. Check the county website for the specific assessment date in your area — this is when the new value takes effect.

What does "millage rate" mean on my tax bill?

The millage rate is the tax rate per $1,000 of assessed value. If your assessed value is $200,000 and the millage rate is 10, you owe $2,000 in tax. The rate varies by county and sometimes by school district or municipality within the county.

Can I dispute my assessed value?

Yes. If you believe the value is wrong, contact the assessor's office about filing an appeal or protest. The important date varies by state — some allow year-round appeals, others have a specific window after the assessment is mailed. Bring documentation such as a recent appraisal or photos showing property condition.
