Indiana Johnson County IN Homestead Exemption Guide
In Indiana, the benefit many homeowners call a homestead exemption is officially called the Homestead Standard Deduction.
Johnson County homeowners file this deduction with the Johnson County Auditor, not the Assessor or Treasurer.
The deduction lowers taxable assessed value. It is different from an assessment appeal, a tax bill payment, a deed recording and the 1% property tax cap.
File homestead deduction questions with the Johnson County Auditor at 86 W Court St, Franklin, IN 46131. Call 317-346-4310 if your deduction is missing, your title changed or you are not sure which form applies.

Deduction amount
How Much Is the Indiana Homestead Deduction in Johnson County?
Johnson County follows Indiana homestead deduction law and state DLGF forms.
The current HC10 form lists the standard deduction as the lesser of 60% of assessed value or $48,000.
A qualifying homeowner also receives the supplemental homestead deduction after the standard deduction is applied.
Use the smaller amount based on the homestead assessed value.
Current form instructions apply 35% to remaining assessed value not over $600,000.
Current form instructions apply 25% to remaining assessed value over $600,000.
Simple $250,000 Johnson County example
Gross assessed value: $250,000.
Standard deduction: $48,000 because it is less than 60% of $250,000.
Remaining value: $202,000.
Supplemental deduction: $70,700 using 35% of $202,000.
Net assessed value before other items: $131,300.
Some older state pages and county examples still show older homestead amounts. Use the current DLGF form, your Johnson County property record and your tax bill year before estimating.
Qualification rules
Who Qualifies for a Johnson County Indiana Homestead Deduction?
The home must be your Indiana principal place of residence when the application is signed.
Owners, recorded contract buyers, qualifying trust occupants and some entity-shareholder situations may qualify.
Indiana generally does not allow an individual or married couple to claim multiple homesteads.
The homestead includes the dwelling, garage, up to one acre around the dwelling and certain residential improvements.
Recorded contract buyer: the contract should be recorded and should require the buyer to pay property taxes.
Trust property: the Auditor may need trust evidence showing a qualifying beneficial interest or right to occupy.
Rental or business use: income-producing portions of a dwelling may not qualify for the homestead deduction.
Mobile or manufactured home: special limits can apply when the home is not assessed as real property.

When the Johnson County Recorder Matters
The Recorder does not approve homestead deductions.
The Recorder matters when your eligibility depends on a recorded deed, recorded contract, trust evidence or ownership history.
Recorded contract buyer: the contract should be recorded if you are claiming the deduction as a contract purchaser.
New deed: make sure the recorded deed and Auditor/Assessor records are aligned after purchase.
Trust property: have the trust or deed language ready if the Auditor needs to verify occupancy or beneficial interest.
Estate or death: ask the Auditor what is needed and use legal help for title-transfer questions.

Common Johnson County Homestead Deduction Mistakes
Calling it an exemption and filing with the wrong office: in Indiana, file the homestead deduction with the county Auditor.
Waiting until the tax bill arrives: the benefit must be filed before the applicable deadline for the bill cycle.
Ignoring title changes: a name change, deed change, trust transfer or ownership change can require review.
Forgetting to vacate a prior homestead: tell the Auditor if you moved or stopped using the property as your principal residence.
Confusing deductions with tax caps: the 1% cap is separate from the standard and supplemental deductions.
Using an old $45,000 example: check the current HC10 form and current tax-bill year before estimating.
Assuming a tax payment office can approve a deduction: the Treasurer handles bills and payments, not deduction approval.
Decision path
What Should You Do Next?
I just bought a Johnson County home: search Beacon, confirm ownership, then file with the Auditor as soon as you occupy the home.
I do not know my parcel number: use Beacon with address search and copy the parcel ID from the property summary.
My deduction is missing: email jcauditor@co.johnson.in.us with your name, address, phone number, parcel number and deduction type.
My assessed value looks too high: contact the Assessor and review your Form 11 appeal timing.
My bill amount or payment is wrong: confirm the deduction first, then contact the Treasurer about the bill.
I am 65, disabled or a veteran: open DLGF deduction forms and ask the Auditor which current form and proof are needed.
I moved or rented the home: file the change-of-use notice quickly to avoid back taxes and penalties.
