Johnson County Property Tax Appeal, Indiana

Travis BunnTravis Bunn·Updated July 22, 2026

Johnson County is located in central Indiana, with Franklin serving as the county seat and Greenwood as the largest city with a 2026 population of approximately 70,440. The county has an estimated population of 174,262 as of 2025 and is the 11th most populous county in Indiana. Johnson County homeowners pay an average of $1,753 in annual property taxes on median home values of $240,700, resulting in an effective tax rate of 0.73%, which is below the national median rate of 1.02%. Property tax appeals matter here because approximately 25% of homes nationally are overassessed, and with property values continuing to rise in growing areas like Johnson County, homeowners may be paying more than necessary due to over-assessments or missed exemptions.

On the typical Johnson County home, valued near $240,700 at the county’s effective tax rate of 0.73%, an over-assessment of even 10% means you are overpaying year after year until you appeal it. Here is how to find out if yours qualifies.

How Johnson County Assesses Property

100%of market value

Assessed by: Johnson County Assessor's Office

Assessment cycle: annual

Notices typically mailed: April (by April 15)

Indiana assesses property at 100% of market value, meaning your assessed value equals your property's fair market value. For example, if your home's market value is $240,700 (the county median), at Indiana's 100% assessment ratio your assessed value would be $240,700. After applying the standard homestead deduction of $40,000 and supplemental deduction of 40% on the remaining value, your taxable assessed value would be approximately $120,420, resulting in approximately $1,753 in annual taxes at the county's effective rate of 0.73%.

The Appeal Process

Appeals are heard by the Property Tax Assessment Board of Appeals (PTABOA). PTABOA hearings are held between 9 a.m. and 4 p.m. at the county administrative building in Franklin. Board members will review your evidence and ask questions about your property valuation. You should be prepared to present objective evidence including comparable sales, photographs, and documentation of any property defects or errors in the assessment record.

1

File Form 130 (Taxpayer's Notice to Initiate an Appeal) with the Johnson County Assessor's Office by June 15, 2026, detailing the facts supporting why your assessed value is incorrect. You can file online at jcmaps.org, by mail, email, or in person.

2

Attend an informal conference with the local assessing official. The assessor will review your evidence and make a recommendation either approving or denying your appeal. This preliminary meeting allows you to present comparable sales, photos, repair estimates, and other supporting documentation.

3

If the informal review denies your appeal, it will automatically be forwarded to the Property Tax Assessment Board of Appeals (PTABOA) for a formal hearing. PTABOA meetings are held between 9 a.m. and 4 p.m. at 86 West Court St in Franklin.

4

Present your case at the PTABOA hearing with all supporting evidence including comparable property sales, photos showing property defects, contractor estimates for needed repairs, and copies of your property record card highlighting any errors.

5

If the PTABOA denies your appeal, you can file an appeal with the Indiana Board of Tax Review within 45 days of receiving the PTABOA decision. If denied by the Indiana Board of Tax Review, you may seek judicial review through the Indiana Tax Court.

Frequently Asked Questions

What is the deadline to appeal my property taxes in Johnson County for 2026?
The deadline to file a property tax appeal in Johnson County for the 2026 assessment year (taxes payable in 2027) is June 15, 2026. This deadline applies if your Form 11 assessment notice was mailed before May 1. If your notice was mailed after April 30, the deadline moves to June 15 of the year your tax statements are mailed. Missing this deadline means you must wait until the next assessment year to appeal, so it's critical to file by early June to ensure your appeal is received on time.
How do I file a property tax appeal online in Johnson County?
Johnson County offers a convenient online filing system through jcmaps.org. To file your appeal online, visit the website and enter identifying information for your property such as your address, name, or parcel number. Then click the blue 'File an Appeal' button, which will walk you through the process of filing Form 130 for your 2026 assessment. You can also download Form 130 from the Indiana Department of Local Government Finance website at in.gov/dlgf or from johnsoncounty.in.gov, and submit it by mail, email, or in person at the Assessor's Office at 86 W Court St in Franklin.
What is the homestead deduction worth in Johnson County in 2026?
For the 2026 assessment year, Johnson County homeowners receive a standard homestead deduction of $40,000 off their assessed value, plus a supplemental deduction of 40% of the remaining value. For example, on a home assessed at $240,700, you would subtract $40,000, leaving $200,700, then deduct 40% ($80,280) more, resulting in a taxable assessed value of $120,420. You also receive an automatic 10% homestead tax credit (up to $300) applied directly to your tax bill. Combined, these benefits can save the median homeowner over $1,000 annually compared to paying taxes on the full assessed value.
What happens at a PTABOA hearing in Johnson County?
After you file your Form 130 appeal, you'll first have an informal conference with the county assessor's office. If that doesn't resolve your appeal, it moves to the Property Tax Assessment Board of Appeals (PTABOA) for a formal hearing. PTABOA meetings are held between 9 a.m. and 4 p.m. at the county administrative building at 86 West Court St in Franklin. During the hearing, board members will review your evidence and ask questions about why you believe your assessment is too high. You should bring comparable sales data from your neighborhood, photos of any property defects or needed repairs, contractor repair estimates, and documentation of any errors on your property record card. The board will issue a written decision, and if you disagree, you can appeal to the Indiana Board of Tax Review within 45 days.
How much can I save by appealing my property taxes in Johnson County?
Successful property tax appeals in Johnson County save homeowners an average of $631 per year according to recent data. However, your actual savings depends on how much your property is overassessed. With approximately 25% of homes nationally being unfairly overassessed, and with Johnson County's effective tax rate of 0.73%, even a $50,000 reduction in assessed value would save you approximately $365 per year. For a property overassessed by $100,000, you could save $730 annually. These savings continue year after year, making a successful appeal valuable for long-term homeowners. The appeal process is free if you file it yourself.
What evidence do I need for a successful Johnson County property tax appeal?
To win your Johnson County property tax appeal, you need objective evidence that your assessed value exceeds your property's true market value. The strongest evidence includes recent comparable sales from your neighborhood showing similar homes sold for less than your assessment, photographs documenting property defects or needed repairs, contractor estimates for repair costs, and a copy of your property record card highlighting any errors in square footage, bedroom/bathroom count, or features that don't exist. A recent independent appraisal can also be powerful evidence. During informal review and PTABOA hearings, board members respond to data and facts, not emotions or complaints about high taxes. The more documentation you provide showing your home is worth less than its assessed value, the better your chances of success.
Can disabled veterans get property tax exemptions in Johnson County?
Yes, Indiana offers significant property tax relief for disabled veterans in Johnson County. Veterans with a 100% service-connected disability rating or Individual Unemployability (IU) status qualify for a complete property tax exemption on their primary residence with no home value cap, meaning they pay zero property taxes. Veterans with 10%-90% service-connected disability who served during wartime receive a $350 annual tax credit, and if they're also age 62 or older, they receive an additional $250 credit for a combined maximum of $600. These benefits apply regardless of home value as of 2026. Veterans should apply through the Johnson County Auditor's office or contact the County Veteran Service Officer for assistance with applications.
How does Johnson County assess property values each year?
Johnson County conducts annual assessments of all properties using a mass appraisal system. The county assessor's office reviews approximately 70,000 parcels each year, using recent sales data (sales disclosures) to establish land rates and property values in each neighborhood. Indiana assesses property at 100% of market value, so your assessed value should equal your home's fair market value as of January 1 of the assessment year. The assessor utilizes recent sales of comparable properties, adjusts for location and amenities, and reviews property characteristics. Assessment notices are mailed by April 15 each year. If you believe your assessment is incorrect, whether due to errors in your property record, failure to account for needed repairs, or assessed value exceeding recent comparable sales, you have the right to appeal by June 15.
