Sangamon County Parcel Search: Tax Parcel Viewer and Property Tax Search
A Sangamon County parcel search, whether in Springfield or out in the townships, comes down to two free county tools: the Tax Parcel Viewer map and the county’s property tax search. Here is how each one searches, what the viewer’s layers show, and the number-format quirks that trip people up.

The Sangamon County Tax Parcel Viewer
The Tax Parcel Viewer, titled “Sangamon County IL - Parcel Viewer,” opens with an agreement you accept by clicking OK. Its search menu offers five modes:
- Parcel Number
- Parcel Address
- Parcel Owner
- Subdivision
- Clicking on the map
The viewer has a note for mobile users and suggests Firefox for anyone having trouble on Android.
Aerials and layers in the parcel viewer
The viewer is stronger than most on historical imagery. You can switch between aerials from 2023, 2019, 2015, 2011, 2007, 2003, 1983 and 1969. Comparing a recent photo with 1969 or 1983 shows when a house, pond or subdivision appeared. Other layers include:
- FEMA flood zone
- Soils
- Farm land use
- 2007 topography
- 4-year sales
- 100-scale and 400-scale PDF index grids that point to the county’s PDF map sheets
Soils and farm land use are handy for farmland buyers, and the sales layer gives a quick look at nearby transfers. For more on flood layers, see FEMA flood zones in county parcel viewers.
Sangamon parcel numbers and tax search tips
The county’s tax search explains its own formatting rules:
- Parcel numbers are 11 digits. In most cases the fifth digit is a zero. You do not need spaces or dashes.
- Owner searches go last name, then first name.
- Address searches use separate fields. On single-digit numbered streets, you may need a leading zero.
The same search is where you start to pay taxes online or file an assessment complaint, so it is the practical tax side of a Sangamon County parcel search.
More Sangamon County GIS maps and records
The county’s interactive maps gallery has more apps, including a PLSS locator for legal descriptions, school and fire district maps, and an aerial comparison running back to 1939. The Recorder’s land records search covers deeds and other recorded documents, and the county’s property information page ties the offices together.
Step-by-step Sangamon County parcel search
- Open the Tax Parcel Viewer and accept the agreement.
- Search by address or owner, or click the parcel on the map.
- Copy the 11-digit parcel number.
- Paste it into the tax search, without dashes, to see the bill.
- Use the Recorder’s land records search for the deed and legal description.
If the Sangamon parcel viewer is down
On a phone, use the mobile link or try another browser, as the viewer suggests. If the map will not load at all, the tax search still finds parcels by number, owner or address without a map. You can also reach the viewer from Sangamon County in our Illinois directory.
Find other Illinois parcel viewers
Platbookmapper keeps a free, county-by-county directory of official parcel viewers and county GIS maps across the United States. The Illinois county GIS page lists every county in the state. If you research land in more than one county, start at the all-states directory or pick a county on the national parcel map, and you will land on the official viewer instead of a data-broker copy.
Frequently asked questions
How many digits is a Sangamon County parcel number?
Eleven. The county notes that the fifth digit is usually a zero, and you can leave out spaces and dashes.
Can I search the Sangamon parcel viewer by owner?
Yes. The Tax Parcel Viewer searches by parcel number, address, owner or subdivision, or you can click the map.
Does the Sangamon viewer have old aerial photos?
Yes. It has aerials back to 1969, and the county’s map gallery has a comparison tool going back to 1939.
Why does my Sangamon address search fail?
On single-digit numbered streets you may need a leading zero, and the street goes in its own field.

Start from the county’s property tax search. Look up the parcel, then follow the payment option.
