Indiana counties are mailing the Notice of Assessment of Land and Structures/Improvements (Form 11) right now. If the assessed value looks higher than what your home could sell for, you have every right to challenge it but the clock is ticking.
What Exactly Is Form 11?
Form 11 is your county assessor's annual opinion of what your property was worth on January 1 of the assessment year. It drives how much tax you'll pay next year.
- Land Value – the price per acre or lot size
- Improvements – everything built on the land: house, garage, deck, pool, etc.
- Total Assessed Value – the sum that shows up on your property-tax bill
A sudden jump often happens when:
- Recent high-priced sales in your neighborhood influence the mass-appraisal model.
- Building permits flag renovations (kitchen remodel, finished basement).
- Data errors — square footage, condition, or even a wrong property record.
Appeal Deadlines You Cannot Miss
| If Form 11 Was Mailed… | Your Appeal Deadline |
|---|---|
| Before May 1 | June 15 of the same year |
| On or After May 1 | 45 days from the mailing date printed on the notice |
Miss the deadline and you're locked into the higher assessment for an entire tax cycle.
Pro-tip: The appeal deadline is in the top-right corner of the Form 11. Mark it in your calendar immediately.
Traditional Appeal Process (Form 130)
- Pick up Form 130 – Taxpayer's Notice to Initiate an Appeal for each parcel.
- Pull three to five comparable sales from MLS or public records.
- Attach photos, repair estimates, or an independent appraisal (Minimum $450).
- File in person or by certified mail with the county assessor.
- Wait months for an informal meeting, then possibly a PTABOA hearing.
