Clark County sits at the southern hinge of Indiana — Jeffersonville and Clarksville pour directly into Louisville's metropolitan economy across the Ohio River, and the county's housing stock reflects that cross-state pull. The 2026 assessment cycle has surfaced the same pattern Clark County owners saw in 2025: high-rate Jeffersonville Township parcels carrying the heaviest combined tax rates in the county, while the southern river-front districts continue to absorb price growth from Louisville-side demand.
This guide walks through what makes Clark County's 2026 Form 11 cycle distinct, the township rate dispersion that makes one ZIP code 50% more expensive than another, and the practical filing logistics for an appeal.
Clark County 2026 calendar. Assessment notices arrive in the spring; spring tax due May 10, 2026; fall tax due November 10, 2026. Form 130 appeal deadline: June 15, 2026, or 45 days after the Form 11 mailing date — whichever is later.
The Cross-River Effect on Clark County Values
Clark County is one of the few Indiana counties where the comparable-sales evidence used in trending analysis is meaningfully shaped by a neighboring state's market. Sales in Jeffersonville frequently reflect Louisville-side buyer demand — particularly in the New Albany corridor that crosses into Floyd County and the Jeffersonville waterfront that benefits from Big Four Bridge pedestrian access.
The DLGF's trending model uses Indiana sales only to set Indiana AVs. But the buyers behind those sales often came from across the river, which means Clark County's AV growth tracks Louisville's metro housing pressure as much as it tracks Indiana's interior. For 2026, that has meant continued upward pressure on residential AVs in Jeffersonville and Clarksville townships and a comparatively quieter cycle in the rural eastern townships (Bethlehem, Charlestown's outer ring, Owen).
Township Rates: Why Your Address Matters
Clark County's township rates fan out widely. Jeffersonville Township carries the highest combined rate in the county — roughly $2.60+ per $100 of net AV in some districts, well above the rural-township rates closer to $1.40. That dispersion reflects the combination of city-of-Jeffersonville services, school referendum levies in Greater Clark County Schools, and special taxing districts inside city limits.
| Township area | Profile | Rate band |
|---|---|---|
| Jeffersonville (city) | Urban, highest service load | Top of county |
| Clarksville | Town services, mixed residential | Upper-mid |
| Charlestown | Mid-county, growing residential | Mid |
| Borden / Bethlehem / Owen | Rural east | Bottom of county |
A practical implication: two physically similar homes a mile apart but on opposite sides of a township boundary can carry tax bills 30–50% apart. Always check the district code on the Form 11 — and on any property you're considering buying in the county.
What to Verify on the 2026 Form 11
The statewide Form 11 walkthrough covers the basics. Clark County specifics:
River and Floodplain Adjustments
Properties along the Ohio River (lower-Jeffersonville waterfront, Utica, Bethlehem) carry floodplain coefficients on the land-value side. A floodplain coefficient that fell off in error inflates the land AV — confirm yours against the prior year's notice.
Bridge Proximity Premium
Big Four Bridge proximity has produced sustained AV growth in lower Jeffersonville. If your Form 11 shows a large land-value jump and you're inside the Big Four walking radius, the AV is likely defensible against sales evidence — but verify the improvement-value side hasn't been double-counted.
Charlestown and Riverside-Subdivision Class Coding
Charlestown's annexation history has produced class-code drift on subdivision parcels. A homestead inadvertently coded as rental loses the 1% cap and the SB 1 $300 credit — fixable, but only if you catch it on the notice.
Homestead Filing Timing
Buyers who closed late in 2025 should call the Clark County Auditor to confirm the homestead filing posted before the 2026 roll. A missing homestead deduction on the 2026 Form 11 is the single most common — and most expensive — Clark County error.
Clark County By the Numbers

| Largest city | Jeffersonville |
| Approximate population | ~125,000 |
| Townships | 11 |
| Top combined rate (2026) | ~$2.60 / $100 net AV (Jeffersonville Township areas) |
| Bottom combined rate (2026) | ~$1.40 / $100 net AV (rural townships) |
| Spring tax due | May 10, 2026 |
| Fall tax due | November 10, 2026 |
SB 1 and the 2026 Homestead Credit in Clark
The 10% / $300 supplemental homestead credit appears on Clark County 2026 spring bills as a new line item below the cap calculation. For Jeffersonville Township homesteads at the 1% cap, the credit math typically lands like this:
- Net AV $200K, 1% cap → $2,000 capped bill
- 10% credit, capped at $300 → $200 credit
- Final spring + fall obligation: $1,800 split across two installments
Higher-AV homesteads in Jeffersonville's growth corridors more often reach the $300 ceiling. Rural-township homesteads at lower combined rates may not be cap-bound at all — for those, the credit is calculated against the gross tax rather than the cap, and the savings still hit but are more tightly tied to the AV figure on the Form 11.
Filing a Clark County Form 130
Clark County accepts Form 130 petitions at the Assessor's office in Jeffersonville. Filing logistics:
- One petition per parcel.
- Hand-deliver or certified-mail in the final week. Mail submitted close to the deadline that arrives after the deadline is rejected — postmark does not control receipt date.
- Attach evidence at filing. Comparable sales from the trending window, photos of any condition deficiencies, and (for income properties) a current rent roll.
- Track acknowledgment. Clark County PTABOA issues written acknowledgment within 30 days; follow up before day 45 if you haven't received it.
- Pay during pendency. Indiana requires payment of the prior year's tax × current rate while a petition is open.
The Indiana property tax appeal guide walks through the full process including the PTABOA hearing, settlement negotiations, and escalation to the Indiana Board of Tax Review.
When the Numbers Justify an Appeal
The strongest Clark County appeal candidates are:
- Jeffersonville Township homes with AV growth above the neighborhood-code median — high township rates magnify the dollar value of any AV reduction.
- Waterfront and Big Four-corridor parcels where land-value methodology is contested by neighboring sales evidence.
- Annexed-in subdivision parcels with class-code or district-code errors.
- New-construction parcels completed late in 2024 or during 2025 where builder estimates and final assessed values diverge.
