County Assessor Search: Property Records for All 50 States and DC

How to Use This Directory

Three steps take you from a county name to the official parcel search. Every county page follows the same order, so once you know one page, you know them all.

1. Pick your state and county

   Open the state page for where the property sits, then choose the county, parish, borough, or city that holds the record. The page names the local assessing office and links to its official website.

2. Open the official parcel search

   Follow the link to the government office and search by parcel number, address, or owner name. A parcel number gives the cleanest match, and a street address is the easiest one to type.

3. Read the record, then act

   The record shows the owner, the assessed value, and any exemption on the account. Compare those figures with your notice, and use the appeal route and the deadline printed on the notice if something looks wrong.

Six Common Property Tasks, Answered

Every county page covers the same six tasks. Here is what each one gives you and what the office will show you when you arrive.

• 
  

  Find my county assessor

  You need the office that keeps the record for your property, and that office changes from one county to the next. Choose your state and your county, parish, borough, or city, and the page names the assessing office and the state agency that sets the rules. The valuation date, county seat, and 2020 population sit on the same page, so you can tell you are in the right place.

• 
  

  Look up a parcel record

  A parcel record is the file the office keeps for one piece of land, and each one has a parcel number. You can find that number on a tax bill or a notice of assessment. The office search takes a parcel number, a street address, or an owner name, and the result shows the owner, the assessed value, the land size, the structures, and the sale history.

• 
  

  Check my property value

  The assessor sets the assessed value on your property, and that number drives the bill. Staff set a market value first, and state law then applies a ratio. Georgia assesses at 40 percent of market value, and other states assess at 100 percent. Compare the value on the record with the number on your notice, and keep both in front of you.

• 
  

  Find exemptions and homestead

  Exemptions lower the taxable value of your property. Programs such as homestead, senior, veteran, and disability exemptions each have their own rules, and your state decides which ones apply and how you file for them. The state page lists the programs with their filing dates, so you can file in time and see the lower value on your next bill.

• 
  

  Appeal an assessment

  An appeal asks the county to review your property value. Many counties give you 25 to 60 days from the notice, and some states use a fixed date, such as April 1 in New Jersey or June 1 in Colorado. If the property details are wrong, ask the office for a correction first. If the value looks wrong, file with the board named on the notice before the deadline.

• 
  

  Read my tax bill

  The bill comes from the collector, not from the assessor, and the collector takes the payment. Taxing units set the rates, and the bill lists each one, so you can see what you are paying for. A question about a value goes to the assessor, and a question about a bill or a due date goes to the collector.

State Assessor Agencies and Valuation Dates

The map above opens every state page. This table lists the county count, the state agency that sets assessment rules, and the valuation date each office uses. The counts cover counties, parishes, boroughs, census areas, independent cities, and municipalities.

The District of Columbia has no county layer in this directory. It is a single jurisdiction, so its own state page names the Office of Tax and Revenue, the state agency, and the local rules. New York sets the assessment date by municipality, so the state has no single valuation date. A county can run its own schedule, so confirm the date with the local office.

How Property Assessment Works

The order below is the order the work happens in. It is the same order the county pages use, so you can read one page and carry the idea to any county in the country.

1. The office records the property

   Every parcel has an account on the assessment roll with an owner, a legal description, a property class, and a parcel number. The number ties the record to a map and a taxing district, which makes it the most reliable key.

2. A market value gets set

   Staff compare recent sales of similar property and adjust for size, age, condition, and location. The result is a market value as of the valuation date listed for that state in the table above.

3. The assessment ratio applies

   State law applies a ratio to the market value, and that produces the assessed value. Some states assess at full market value, others at a fraction such as 40 percent, and a few cap how fast a home’s value can rise each year.

4. Relief and exemptions apply

   Programs such as homestead, senior, veteran, and disability exemptions lower the taxable value. What remains times the rates set by each taxing unit becomes the property tax bill.

5. You review, then appeal

   The office mails a notice with the value and the date for a protest. If the record is wrong, ask for a correction first. If the value looks wrong, file with the board named on the notice before the deadline.
