If you own ten or more acres of Indiana woods, there is a state program that assesses that land at $17.74 per acre for 2026. Not $17.74 in tax — $17.74 of assessed value, per acre, before the tax rate even applies. For comparison, the DLGF's certified agricultural base rate for the same assessment year is $2,120 per acre.
The program is the Classified Forest & Wildlands Program, run by the Indiana DNR Division of Forestry, and it is one of the largest percentage property tax reductions available anywhere in Indiana law. It is also underused: plenty of rural landowners pay full freight on wooded back acreage for years without knowing the program exists.
The 2026 Numbers
The assessment rate for classified land is set by statute and adjusted annually for inflation. Each January the DLGF publishes the new figure; the January 9, 2026 memo walks through the math:
| Item | Value |
|---|---|
| Rate for the preceding assessment year (Jan 1, 2025) | $17.24 |
| CPI-U adjustment for calendar 2024 | × 1.029 |
| Assessment rate for January 1, 2026 | $17.74 per acre |
The same rate applies to land classified as native forest land, forest plantation, or wildlands under Ind. Code 6-1.1-6-14, as a windbreak under Ind. Code 6-1.1-6.2-9, or as a filter strip under Ind. Code 6-1.1-6.7-9.
What Unclassified Woodland Pays Instead
Woodland that is not enrolled is typically assessed as agricultural woodland: the certified base rate with a negative influence factor (commonly an 80% reduction). Against the 2026 base rate of $2,120, that works out to roughly $424 per acre of assessed value — about 24 times the classified rate. On 40 acres of woods at a 1.5% effective rate, that's the difference between roughly $250 a year and roughly $11 a year.
The gap widens further if your woods are being carried as excess residential acreage rather than agricultural land — a classification error worth checking on its own. Our farmland base rate appeal guide covers how land-type breakdowns drive rural assessments.
Note
The 2026 agricultural base rate actually fell — from $2,390 to $2,120 per acre, per the DLGF's January 2, 2026 certification. Even after that drop, classified land's $17.74 rate remains a small fraction of any alternative classification.
Who Qualifies
The DNR's program requirements are straightforward:
- At least 10 contiguous acres of forest, wetland, shrubland, and/or grassland
- A professionally written management plan you agree to follow
- The land must be kept in its natural, productive condition — no grazing livestock in the classified woods, no development on the enrolled acres
Enrollment does not lock the land away from you. Timber harvesting under the management plan is allowed (and encouraged — timber production is one of the program's stated purposes), as are hunting, hiking, and other recreational use. You can sell the land; classification runs with the property.
How to Enroll
- Contact your DNR district forester. They administer the program regionally and can tell you quickly whether your acreage qualifies.
- Get the management plan written. A professional forester prepares a plan covering timber, watershed, and wildlife objectives.
- File the classification application. Once approved, the classification is recorded and the assessor carries the enrolled acres at the classified rate beginning with the next assessment date.
There is no annual fee to remain in the program. Your obligation is ongoing compliance with the management plan, and the DNR does periodic inspections.
The Withdrawal Catch
The tax break is a bargain with the state, and unwinding it costs money. Withdrawing land from classification (or violating the terms so that the DNR withdraws it for you) triggers a withdrawal penalty designed to recapture the taxes you saved, calculated over as many as ten prior years, plus interest. Anyone considering enrollment ahead of a likely sale to a developer should run the withdrawal math first — the program rewards long-horizon ownership, not short-term parking. Confirm the current penalty computation with your district forester before signing, and again before withdrawing.
Check Whether Your Woods Are Already Classified
If you bought rural acreage recently, the prior owner may have enrolled it decades ago — or may have paid full price on eligible woods for decades. Two checks:
- Pull your parcel in our Indiana property explorer or property lookup and look at the assessed value per acre on the wooded portion. Land carried near $17–18 per acre is classified; land near $400+ per acre is not.
- Read your property record card. The land detail section shows acreage by type. Misallocated acreage — woods carried as tillable, or as residential excess acres — is one of the most fixable errors in rural assessments, appeal or no appeal.
If the acreage breakdown is wrong, that's a factual correction your assessor can make, and our tax appeal service handles the cases where the county pushes back.
