Brown County is unlike anywhere else in Indiana. Nashville, the county seat, is a tourism town built around arts, crafts, and the surrounding hills of Brown County State Park. The county has the lowest population density of any in central Indiana, the highest share of forested land, and a residential mix that includes second homes, short-term rental cabins, year-round residences, and a small commercial core in Nashville itself. The effective property tax rate runs around 0.67% — well below the statewide median — but the underlying property mix means the SB 1 reforms land here in distinctive ways.
Three Property Profiles in One County
Nashville Tourism Commercial
The Nashville core is a dense cluster of small commercial parcels — galleries, restaurants, retail, lodging — operating on the 3% commercial cap. The 2026 changes most relevant here:
- The DLGF base-cost reset that drove 2025 commercial AV growth carries forward into 2026 trended values
- The new business personal property exemption rising to $1M removes filing burden for most small Nashville operators
- Cap-bound parcels respond to AV moves differently than non-cap-bound ones
Second Homes and Short-Term Rentals
Brown County's residential stock includes a meaningful share of cabins, second homes, and short-term rentals scattered through the hills around Nashville and Bean Blossom. These properties are not homestead-eligible. They carry the 2% other-residential cap, get no standard or supplemental homestead deduction, and don't qualify for the new SB 1 $300 credit.
The new rental/farmland 2% deduction, starting at 13.3% in 2026, does apply to rented residential property — including short-term rental cabins held primarily for rental use.
Short-term rental classification matters in Brown County. A cabin used primarily for rental use is a 2%-cap rental property, not a homestead. A cabin used as a primary residence with occasional rental use can qualify as a homestead. The line between these is documentation-driven; assessors look at days-of-use, electric usage, vehicle registrations, and tax filings.
Year-Round Residential
For Brown County residents who live in their home full-time, 2026 brings the same SB 1 benefits as the rest of the state:
- New 10% supplemental homestead credit, capped at $300
- Supplemental homestead deduction rising from 35% to 40%
- Spring 2026 bill is meaningfully lower than the same parcel under 2025 rules
What Tourism Means for the Tax Base
Brown County's commercial AV is concentrated in Nashville's arts-and-tourism core, with a smaller perimeter of supporting commercial elsewhere in the county. When tourism softens (as it did during 2020-2021), commercial AV pressure rises and rates can shift upward to maintain the levy. When tourism is strong, the commercial base broadens and rates can ease.
For 2026, the commercial AV picture follows the statewide pattern of trended values reflecting the 2025 base-cost reset. For Nashville-core commercial owners, the most defensible 2026 appeal angles are condition documentation and verified comparable sales — the latter being challenging in a market with low sales volume relative to the parcel inventory.
What to Check on Your Brown County Form 11
The general Form 11 walkthrough applies. Brown-specific items:
Homestead vs. Second-Home Classification
This is the largest single tax-bill issue in Brown County. Verify that a primary residence is coded as homestead (1% cap, full deductions, SB 1 credit) and a second home or rental cabin is coded appropriately (2% cap, no homestead benefits, but eligible for the new 13.3% rental deduction).
Land vs. Improvement Split
Brown County's hilly, forested terrain produces unusual land valuations. Heavily wooded acreage or steep-grade land carries different productivity than the assessor's standard land schedule sometimes assumes. Verify the land valuation against actual topographic and forest-cover conditions.
Forest Reserve Classification
For larger parcels with substantial forest cover, Indiana's Forest Reserve classification can produce meaningful AV reductions. Verify whether your parcel qualifies and whether the classification is currently in place.
Short-Term Rental Tax Status
If your property is operated as a short-term rental, verify that the classification on your Form 11 reflects that use. Misclassification in either direction (homestead claimed on a rental, or rental treatment on a primary residence) creates appeal exposure and potential back-tax liability.

Filing a Brown County Appeal
The Form 130 appeal process follows the statewide framework. Local notes:
- Filing destination: Brown County Assessor's Office, Nashville
- Topographic adjustments: bring photos and topographic maps for any land valuation appeal
- Forest cover documentation: county forester records or aerial imagery support forest reserve classifications
- Short-term rental income: if appealing on a rental basis, bring rental income records to support the rental classification
- Comparable sales: low sales volume means comparables sometimes need to be pulled across longer time windows; note the timeframe in your filing
For most Brown County residential appeals, the strongest case is built on a combination of land valuation challenges (topography, forest cover) and condition documentation. For commercial appeals in the Nashville core, the strongest cases combine sales evidence with operating data.
A Note on Investor Buyers
Brown County's cabin and second-home market draws investor and lifestyle buyers from across the Midwest. For investor pro forma analysis:
- 2% other-residential cap applies (not 1% homestead) unless the buyer establishes residency
- No standard or supplemental homestead deduction
- No SB 1 $300 credit
- For rental use, the new 13.3% rental deduction does apply
- Mortgage deduction available regardless of residency
For year-round residents considering a rental property purchase in Brown, the math differs meaningfully from Marion or Hamilton County rental analysis given the lower base AVs and lower effective rates.
What Nashville Owners Should Do Next
Three steps for Brown County owners between Form 11 arrival and the May 11 spring deadline:
- Confirm the classification on each parcel (homestead, second home, or rental)
- Verify land valuation against actual topography and forest cover
- Compare your AV against comparable parcels in Property Lookup
