Jackson County homeowners pay a median of $881 a year in property tax on a median home value of $178,300. Its effective tax rate (property taxes paid as a share of home values, per the Tax Foundation) is 0.53%, the 80th highest of 92 Indiana counties. The Jackson County Assessor values homes in Jackson County as of January 1 each year (in a few townships an elected township assessor does this). The Jackson County Property Tax Assessment Board of Appeals (PTABOA) hears appeals the assessor cannot settle.
Closed for 2026Closed for 2026 in counties that mailed Form 11 notices before May 1 (the deadline was June 15, 2026). The next window opens when 2027 notices arrive in spring 2027, with a deadline of June 15, 2027; if your county mailed its 2026 notice on or after May 1, your 2026 appeal is also due June 15, 2027.
File Form 130 with the assessor by June 15 of the assessment year if the Form 11 notice was mailed before May 1. If the notice was mailed on or after May 1 (or none was sent), the deadline is June 15 of the next year, when the tax bill is mailed. The exact deadline is printed on your Form 11. Example: Monroe County mailed 2026 Form 11 notices on April 28, 2026, and the deadline to appeal the 2026 value was June 15, 2026. Separately, certain errors (assessment against the wrong person, a math or clerical mistake, a wrong description of the property, a missed deduction or credit) can be raised on page 2 of Form 130 up to three years after the taxes were first due.

In most townships the county assessor sets your home's assessed value (a few townships have their own township assessor who does this), mails the Form 11 notice, receives your Form 130 appeal and holds the informal meeting before the PTABOA hearing.
The assessor mails a Notice of Assessment (Form 11) showing your land and building values and the appeal deadline. In recent years counties have mailed it in late April (for example Boone and Monroe counties mailed their 2026 notices on April 28, 2026). If no Form 11 is sent, your tax bill serves as the notice.
Look up your home on the Jackson County Assessor website and check square footage, bathrooms, condition and features. Mistakes are the easiest wins. Use our record card checklist.
File Form 130 with the Jackson County Assessor (or your township assessor, if your township has one) by the deadline printed on your Form 11 notice, usually June 15. The assessor then sets up an informal meeting; if you do not agree, the Jackson County PTABOA holds a hearing.
Your own recent purchase price (an arm's-length sale) or a recent purchase offer; Sales of comparable homes near the assessment date, with an explanation of how they compare (size, age, condition, location); An appraisal by a licensed appraiser, tied to the January 1 assessment date (helpful but not required); Corrections to your property record card (square footage, finished basement, garage, condition).
Usually the current assessment is presumed correct and you must prove a different value. But if your assessment rose more than 5% over the prior year's, the burden shifts: the assessor must prove the value is correct, unless the increase came from new construction, renovations, zoning or use changes not counted the year before. If the burden has shifted and neither side proves a value, the prior year's assessment is used. Evidence must be objectively verifiable and market-based; you do not need an appraisal.
Next step: Indiana Board of Tax Review (IBTR). 45 days after the PTABOA gives notice of its decision (Form 115). If the PTABOA has not decided within 180 days of your Form 130 filing, you may go directly to the IBTR. File Form 131 online through the IBTR's POPLAR portal (which notifies the assessor automatically) or by mail to the IBTR, 100 N. Senate Ave., Room N-1026, Indianapolis, IN 46204, and mail a copy to the county assessor. Attach your Form 130 and the Form 115 decision. One petition per parcel and year. No filing fee is listed on the form or in the IBTR's guides. Hearings are by phone or in person, usually before an administrative law judge; homeowners can use small-claims procedures. Bring labeled exhibits and send them to the IBTR and the assessor so they arrive 5 days before the hearing; evidence from the PTABOA hearing is not carried over. The IBTR must hold the hearing within a year and decide within 90 days after it (it can extend that to 180 days). Its decision can be appealed to the Indiana Tax Court within 45 days.
The official appeal form is 130: Taxpayer's Notice to Initiate an Appeal (State Form 53958).
Open Form 130Enter the market value on your assessment notice and what you think the home would really sell for. We estimate the yearly saving if the board agrees with you.
Some states cap how fast the taxable value of a home can rise (California, Florida, Michigan and Texas homesteads, for example). If your taxable value is already held below market value by a cap, a lower market value may not lower this year's bill.

File Form 130 with the assessor by June 15 of the assessment year if the Form 11 notice was mailed before May 1. If the notice was mailed on or after May 1 (or none was sent), the deadline is June 15 of the next year, when the tax bill is mailed. The exact deadline is printed on your Form 11. Example: Monroe County mailed 2026 Form 11 notices on April 28, 2026, and the deadline to appeal the 2026 value was June 15, 2026. Separately, certain errors (assessment against the wrong person, a math or clerical mistake, a wrong description of the property, a missed deduction or credit) can be raised on page 2 of Form 130 up to three years after the taxes were first due.
File Form 130 with the Jackson County Assessor (or your township assessor, if your township has one); appeals not settled there go to the Jackson County Property Tax Assessment Board of Appeals.
