Indiana's property tax rates vary dramatically from county to county. A home assessed at $200,000 might owe $2,000 in one county and $4,000 in another. Understanding where your county falls in the statewide ranking — and why — can save you real money.
This guide ranks all 92 Indiana counties by effective property tax rate and explains the factors driving the differences.
How Indiana Property Tax Rates Work
Indiana doesn't have a single statewide property tax rate. Instead, rates are set locally by overlapping taxing units — county government, township, municipality, school district, library district, and special districts. Your effective rate is the sum of all applicable levies for your specific location.
This is why two properties in the same county can have different tax rates — they may be in different school districts or municipalities.
Indiana also caps property taxes through its circuit breaker system:
- 1% of assessed value for homesteads
- 2% for residential rental and agricultural property
- 3% for commercial and industrial property
These caps mean that even in high-rate areas, your actual tax bill is limited. But they also mean that some taxing units receive less revenue than their levy would otherwise generate, creating pressure on local services.
What Drives Rate Differences?
Several factors explain why tax rates vary across counties:
School Funding
School districts are typically the largest component of property tax bills. Counties with higher school operating and debt service levies have higher overall rates. Marion County and Lake County tend to have higher school-related levies than rural counties.
Assessed Value Base
Counties with a large assessed value base can generate the same revenue with lower rates. Hamilton County, with high-value residential property in Carmel, Fishers, and Noblesville, can fund services at lower rates than counties with smaller tax bases.
Debt Service
Counties and municipalities that have issued bonds for infrastructure, schools, or public safety carry debt service levies that add to the overall rate. Recent bond issues can spike rates temporarily.
Local Government Efficiency
The number of taxing units and the efficiency of local government operations affect rates. Indiana has over 2,900 taxing units statewide — consolidation efforts in some counties have helped reduce overhead.
High-Rate Counties
Counties with the highest effective tax rates tend to share several characteristics: smaller assessed value bases, higher school district levies, and more overlapping taxing units.
Several counties in the Lake County region and parts of central Indiana consistently rank among the highest. Urban areas with older housing stock and aging infrastructure often carry higher debt service obligations.
If you're in a high-rate county, it's especially important to verify that your assessment is accurate. An over-assessment in a high-rate county means you're paying a higher premium on every dollar of excess assessed value.
Low-Rate Counties
Counties with the lowest effective rates typically have:
- Large assessed value bases relative to their levies
- Fewer overlapping taxing units
- Conservative bonding practices
- Efficient government operations
Several suburban counties surrounding Indianapolis — including Hamilton, Hendricks, and Boone — benefit from strong assessed value growth that keeps rates relatively low despite growing service demands.
Rate vs. Bill: An Important Distinction
A low tax rate doesn't necessarily mean a low tax bill. If your county has a low rate but high assessed values, your bill could still be substantial. Conversely, a high rate in a county with low assessed values might produce a modest bill.
What matters most to individual property owners is the effective tax as a percentage of market value. This accounts for both the rate and how accurately properties are assessed.
Counties where assessments run significantly below market value effectively have lower real tax burdens, even if their nominal rates are higher. Our AI Valuation product can estimate the gap between your assessed value and market value.
How to Lower Your Tax Bill
Regardless of which county you're in, several strategies can reduce your property tax burden:
Claim All Deductions
Make sure you're receiving every deduction and exemption you're entitled to. The homestead exemption alone can reduce your assessed value by up to $48,000.
Appeal If Over-Assessed
If your assessment exceeds your property's market value, file a Form 130 appeal. Our Tax Appeal Automation product identifies over-assessed properties and handles the filing process.
Know Your Deadlines
Don't miss payment deadlines — late payments incur penalties that add up quickly.

Methodology
Tax rate data is derived from the Indiana Department of Local Government Finance certified levy and assessed value data. Effective rates are calculated as total certified levy divided by total net assessed value for each county. Individual property rates vary based on the specific taxing units that overlap the property's location.
