Starke County is a small northwest Indiana county anchored by the city of Knox — agricultural land, the Kankakee River floodplain along the southern edge, several inland lakes, and a rural-residential housing stock that has been pulling its weight against the statewide DLGF cost-table reset carried into the 2026 cycle. Form 11 notices typically arrive by mid-April. Spring tax is due May 10, 2026, with the fall installment due November 10, 2026.
For Starke County owners, the 2026 cycle's practical question is the same one facing every smaller Indiana county: does the AV on the upcoming notice reflect actual neighborhood-level sales evidence, or has the cost-table reset overshot what local sales support? The county's modest combined rate stack means AV reductions translate cleanly to bill savings, with relatively few parcels bound by circuit breaker caps.
Starke County 2026 calendar. Form 11 notices typically mail by mid-April. Spring tax due May 10, 2026; fall installment due November 10, 2026. Form 130 appeal deadline: June 15, 2026, or 45 days after the Form 11 mailing date — whichever is later.
Starke County's Submarkets
1. Knox (City of)
The county seat. Standard small-city residential, modest commercial corridor, and the courthouse square. City-of-Knox combined rates run above the rural-township average due to municipal services and school district overlay.
2. Inland Lakes
Bass Lake — the largest natural lake in Starke County — anchors a small but active lake-property market. Smaller lakes (Koontz Lake straddles the Starke-Marshall border, plus several smaller bodies) carry waterfront and water-access parcels priced above the surrounding residential. As with Noble County's lakes country, small-population sales evidence can swing AVs sharply year-over-year for waterfront parcels.
3. Kankakee Marsh and Floodplain
The southern edge of the county along the Kankakee River carries floodplain land that's a mix of agricultural, hunting/conservation, and seasonal. Floodplain coefficients drive land-value treatment here.
4. Rural and Agricultural
The bulk of Starke County's land area. Farmland base-rate movement — set statewide by the DLGF — drives ag-acreage AV more than any local sale.
What to Verify on a Starke County Form 11
The statewide Form 11 walkthrough covers the basics. Starke-specific items:
Bass Lake Frontage and Coefficients
Waterfront parcels carry frontage-foot, access-type, and lake-quality coefficients. A coefficient that updated in error between cycles can produce a major land-side AV swing without any underlying sales evidence. Pull the prior year's notice and compare line by line.
Floodplain Coefficient on Kankakee Parcels
Land along the Kankakee corridor carries floodplain treatment. A coefficient that fell off in error inflates the land AV. Confirm the floodplain treatment on your 2026 notice matches the prior year.
Homestead Status on 2025 Closings
Confirm with the Starke County Auditor that any 2025 closing posted a homestead deduction and the SB 1 $300 homestead credit before the 2026 roll closed.
Acreage Breakdown
The split between tillable, woods, residential homesite, and outbuildings determines per-acre rate application. Stale acreage breakdowns are the most common rural-parcel error category.
Class Code on Lake Cottages
Seasonal lake cottages frequently carry improvement class codes that don't reflect actual condition. A 1960s cottage with original systems assessed at typical-condition cost rates will be overstated. Photos support a class-adjustment appeal.

Filing a Starke County Form 130
The Starke County Assessor's office at the courthouse in Knox accepts Form 130 petitions. Practical filing notes:
- One Form 130 per parcel.
- State your grounds clearly. Market value (with comparable sales), property condition (with photos), or assessment error (acreage, class code, square footage, coefficients).
- Lake-front appeals: lead with same-lake comparables. Cross-lake comps are weaker.
- Floodplain appeals: lead with FEMA-map evidence and any engineering documentation.
- Hand-deliver or certified mail near the deadline. Postmark does not control receipt.
- Track acknowledgment within 30 days.
- Pay during pendency. Indiana law requires payment of the prior year's tax × current rate while a petition is open.

SB 1 Homestead Credit on Starke County Bills
The 10% / $300 supplemental homestead credit appears on 2026 spring bills as a new line item below the cap calculation — for properly-filed homesteads only. A representative Knox-area homestead near the county median:
- AV ~$110K, homestead deductions applied
- Post-cap bill ~$1,000
- 10% credit: $100
- Final spring + fall obligation: ~$900 split across two installments
Lake cottages used as second homes do not qualify. Higher-AV homesteads — particularly waterfront primary-residence parcels on Bass Lake — can reach the $300 ceiling.
When to Appeal in Starke County
Starke County appeal candidates worth pursuing:
- Bass Lake waterfront with sharp year-over-year AV growth. Same-lake sales evidence is the right benchmark.
- Kankakee corridor parcels with floodplain coefficient changes.
- Older Knox housing stock with documented condition deficiencies.
- Rural acreage breakdown errors misallocating ag vs. residential.
- Class-code or homestead-status errors that pushed a homestead out of the 1% cap.
