Indiana boasts a statewide effective property tax rate of roughly 0.76%, sitting comfortably below the national average. The state’s constitution strongly protects homeowners via “Circuit Breaker” caps, ensuring that property taxes on a primary residence cannot exceed 1% of its gross assessed value. Recent 2024 and 2025 legislative sessions have further enhanced these protections by converting senior and disabled deductions into direct tax credits (est., Tax Foundation 2026 / U.S. Census ACS 2023).
With a competitive statewide effective property tax rate of 0.76%, Indiana is highly attractive to both homeowners and retirees. Real property in Indiana is assessed at 100% of its market value-in-use. The state uses a 4-year cyclical reassessment process, meaning assessors physically inspect roughly 25% of the parcels in a county each year. However, property values are “trended” annually to reflect recent neighborhood sales data, meaning your assessed value can change every year even without a physical inspection.
The Constitutional 1-2-3 Property Tax Caps
The hallmark of the Indiana property tax system is the “Circuit Breaker” tax cap, officially written into the state constitution in 2010. This cap strictly limits a property’s maximum tax liability based on its classification and its gross assessed value:
- 1% Cap: Applies to owner-occupied primary residences (Homesteads).
- 2% Cap: Applies to other residential properties (like apartment complexes and rental homes), agricultural land, and long-term care facilities.
- 3% Cap: Applies to commercial and industrial real property, as well as business personal property.
If your local tax rates dictate a bill that exceeds 1% of your home’s gross assessed value, the Circuit Breaker is triggered, and your bill is reduced so that it exactly equals that 1% cap. The Exception: Voter-approved referendums (such as special school funding levies) are explicitly exempt from the caps. This is why residents in some districts may see tax bills that slightly exceed 1% of their home’s value.
Indiana statewide effective rate. On a $225,000 home, expect approximately $1,710 per year at the statewide average. Actual bills depend on your specific county and municipal tax rates (est., Tax Foundation 2026 / Census ACS 2023).
| Home Value | Annual Tax (est.) | Monthly Payment | vs. U.S. Average |
|---|---|---|---|
| $150,000 | $1,140 | $95 | -$210 below avg. |
| $225,000 | $1,710 | $143 | -$315 below avg. |
| $350,000 | $2,660 | $222 | -$490 below avg. |
| $500,000 | $3,800 | $317 | -$700 below avg. |
| $750,000 | $5,700 | $475 | -$1,050 below avg. |

Homestead Deductions and Credits (2024-2025 Updates)
Indiana offers powerful deductions to lower your taxable assessed value before the tax rate is even applied. The most important is the Homestead Standard Deduction, which shields the lesser of 60% of the assessed value or $48,000. Additionally, the Supplemental Homestead Deduction takes another 35% off the remaining value (up to $600,000) and 25% off any value above $600,000.
Recent legislative sessions (2024 and 2025’s Senate Enrolled Act 1) dramatically restructured benefits for seniors and disabled homeowners by converting complicated deductions into straightforward tax credits:
- Over 65 Credit: Replaces the old deduction with a flat $150 tax credit applied directly to the final bill. The income limits are $60,000 for single filers and $70,000 for married couples, and the previous assessed value limit has been removed.
- Over 65 Circuit Breaker Credit: An additional protection for eligible seniors that caps year-over-year property tax liability increases at a maximum of 2%.
- Blind/Disabled Credit: A $125 direct tax credit applied to the final bill for eligible individuals.
- Disabled Veteran Deductions: In 2024, the state expanded the eligibility for disabled veterans by raising the assessed value limit cap to $240,000. For the upcoming 2026 tax year, veterans will see up to a $400 stackable credit.
Major County Tax Rates in Indiana
While the constitutional 1% cap provides a ceiling for homeowners statewide, the actual effective rate you pay depends heavily on your county’s underlying tax base. Most of Indiana’s top 10 most populous counties fall right around the 0.76% to 1.05% mark.
The glaring exception is Lake County (Gary, Hammond). Because of a complex history of deindustrialization, heavy reliance on voter-approved referendums, and high local government costs, Lake County suffers from the highest effective tax rates in the state, averaging nearly 2.68%. Many homes in Lake County hit the 1% constitutional cap, but the sheer volume of exempt referendums pushes the actual tax burden much higher.
| County | Effective Rate | Annual Tax on $225,000 Home | Notes |
|---|---|---|---|
| Marion County | 1.17% | $2,633 | Most populous county (Indianapolis); heavily impacted by referendums. |
| Lake County | 2.68% | $6,030 | Highest effective rate in the state; heavy referendum reliance. |
| Allen County | 0.95% | $2,138 | Includes Fort Wayne. |
| Hamilton County | 0.89% | $2,003 | Wealthy suburban county north of Indianapolis; high home values. |
| St. Joseph County | 1.05% | $2,363 | Includes South Bend. |
| Elkhart County | 0.82% | $1,845 | Northern Indiana manufacturing hub. |
| Tippecanoe County | 0.64% | $1,440 | Includes Lafayette (Purdue University); very low effective rate. |
| Hendricks County | 0.90% | $2,025 | Fast-growing suburban county west of Indianapolis. |
| Vanderburgh County | 0.74% | $1,665 | Includes Evansville; tracks slightly below state average. |
| Porter County | 0.84% | $1,890 | Suburban county east of Lake County; significantly lower rates. |
Disclaimer and Methodology
This calculator provides estimates for planning purposes only, based on effective property tax rates (actual median taxes paid divided by median home values). Indiana law requires all real property to be assessed at 100% of market value-in-use. Because local tax rates vary by township and school district, and because the Homestead Deductions involve complex dual calculations (Standard + Supplemental), this calculator bypasses those intermediate steps. It uses historical effective rates to give you a highly realistic “bottom line” estimate of what homeowners in these counties actually pay.
What this calculator does not account for:
- Your specific Taxing District Rate (which determines whether you hit the 1% Circuit Breaker cap before or after referendums are applied).
- Voter-approved school referendums, which are exempt from the 1% constitutional cap and can cause your bill to exceed 1% of your home’s value (common in Marion and Lake counties).
- The difference between your home’s purchase price and the Assessor’s annual “trended” value.
How to get an accurate estimate:
- Use the Indiana Gateway Public Access Tool to find the precise tax rate for your specific address and township.
- Calculate your Taxable Value by applying the Standard Deduction ($48,000 max) and the 35% Supplemental Deduction to your Gross Assessed Value.
- Ensure your Homestead Exemption is filed with your County Auditor (you only need to file once unless you move or change the deed).
