Search by Address or Owner
If you don’t know your parcel number, you can generally search using other property information.
Having the correct parcel number can be helpful when contacting county offices because it identifies the exact property involved.
You’ll often find the parcel number on your property tax bill or through the online property search.
Understanding Your Assessed Value
Indiana real property is generally assessed according to its market value-in-use.
The Assessor considers property characteristics and market information when determining assessed values.
Factors may include:
- Location
- Square footage
- Lot size
- Age
- Construction
- Condition
- Improvements
- Comparable properties
- Local market activity
Assessments can change through Indiana’s annual adjustment process, even if you haven’t recently bought or improved the property.
Is the Assessor the Same as the Treasurer?
No. These offices have different jobs.
Allen County Assessor: Determines and maintains property assessments.
Allen County Auditor: Handles many property tax deductions, transfers and tax-related records.
Allen County Treasurer: Collects property tax payments.
If your question is “Why is my property valued at this amount?”, start with the Assessor.
If your question is “How do I pay my property tax bill?”, contact the Treasurer.
Correcting Property Information
It’s a good idea to review your property record occasionally.
Look for incorrect information involving:
- Home square footage
- Number or type of structures
- Property classification
- Lot information
- Building features
- Condition
- Improvements
If something appears wrong, contact the Assessor at 260-449-7123.
An incorrect property characteristic could affect your assessment.
Property Assessment Appeals
If you disagree with your property’s assessed value, Indiana provides a process for challenging the assessment.
Before filing an appeal:
- Review your property record.
- Verify that property details are accurate.
- Compare similar properties.
- Gather supporting evidence.
- Review your assessment notice.
- Check the filing deadline.

Property Tax Deductions
The Assessor isn’t the primary office for most property tax deductions.
Deductions such as the Homestead Deduction, Mortgage Deduction and certain senior or veteran deductions are generally handled through the Allen County Auditor.
If your assessed value looks correct but your tax bill seems unusually high, check whether all applicable deductions are being applied.
Before You Call
Having this information ready can make it easier for the Assessor’s Office to help:
- Property address
- Owner’s name
- Parcel number
- Assessment notice, if applicable
- Specific property information you believe is incorrect
- Photos or other documentation if relevant
Local Tip
Use the online property search before calling the Assessor. You may find the assessed value, parcel number and property details you need without making a trip downtown.
If something looks wrong, write down the specific issue before calling—for example, incorrect square footage or a structure that no longer exists.
