By GoGIS · 2025 tax roll, V12 statewide parcels · Updated October 31, 2026

WI 2026 puts all 50,762 parcels in Sauk County on your phone: owner names, site addresses, assessed values and acreage from the county’s 2025 tax roll. The county download is about 16 MB, and once it’s on your phone you can search it and tap any parcel with no signal.

The parcels cover 542,387 mapped acres across 39 towns, villages and cities, and 10 school districts. The most parcels are in the City of Baraboo. The data is the State Cartographer’s Office V12 statewide parcel map, loaded from the county on February 20, 2026.

What the Sauk County records include

Counties fill in the statewide schema differently. This is how complete Sauk County’s 2025 records are:

Sauk County parcel records with each field filled in
Field	Filled in
Owner name	99.9% of parcels
Site (street) address	62.4% of parcels
Assessed or estimated value	88.5% of parcels
Assessed or deeded acres	90% of parcels
Net property tax	88.5% of parcels

Only 62.4% of parcels have a street address, which is normal for rural land: fields and woods often have no house number. Search by owner name or parcel ID to find those.

How the land is classed

By mapped area, Sauk County is agricultural 58%, residential 16%, government-owned / county forest 11%, undeveloped / ag forest 4%. The median estimated fair market value of a residential parcel is $262,200, across 25,194 residential parcels with a value.

In WI 2026, open the legend and color the map by Class of Property to see the same picture, or by Estimated Fair Market Value to see where values rise and fall.

Deer season: public land and Managed Forest Law

The tax roll marks parcels that are government-owned or enrolled in Wisconsin’s forest tax programs. In Sauk County:

Federal-owned: 2,961 acres in 35 parcels
State-owned: 31,946 acres in 1,513 parcels
County-owned: 3,585 acres in 228 parcels
Managed Forest Law, open to public hunting, fishing, hiking, sightseeing and cross-country skiing: 819 acres in 25 parcels
Managed Forest Law, closed (no public access without permission): 69,147 acres

In WI 2026, color the map by Auxiliary Class of Property to see these parcels, and tap one for the owner and acreage. The acreages are whole-parcel areas from the tax roll: a parcel that is only partly enrolled counts in full, and the tax roll doesn’t show posted areas or access routes. Before you hunt, check the DNR’s map of private forest land open to the public and the signs on the ground.
