On the typical DeKalb County home, valued near $112,300 at the county’s effective tax rate of 0.79%, 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.
2026 Appeal Deadline: June 15, 2026 (if Form 11 mailed before May 1) or 45 days from Form 11 notice date
The filing deadline depends on when your Form 11 Notice of Assessment is mailed. If mailed before May 1 of the assessment year, the deadline is June 15 of that year. If mailed on or after May 1, the deadline is June 15 of the following year when tax bills are issued. You have 45 days from the date on your Form 11 notice to file an appeal.

How DeKalb County Assesses Property
Assessed by: DeKalb County Assessor's Office
Assessment cycle: annual
Notices typically mailed: April (before May 1)
Indiana assesses property at 100% of market value using annual trending factors. If your home's market value is $112,300 (the county median), your assessed value would be $112,300. After applying the standard homestead deduction of $48,000 plus the 40% supplemental deduction on the remaining $64,300 ($25,720), your taxable assessed value would be approximately $38,580, resulting in approximately $305 in annual taxes at DeKalb County's effective rate of 0.79%.
The Appeal Process
Appeals are heard by the Property Tax Assessment Board of Appeals (PTABOA). PTABOA hearings are informal proceedings lasting 15-30 minutes where you present your evidence and testimony. The board reviews your case along with the assessor's response and issues a written determination typically within 120 days of the hearing.
Step 1: Review your Form 11 Notice of Assessment when it arrives (typically April). Note the deadline printed on the notice - you have 45 days to file an appeal.
Step 2: Gather supporting evidence including recent comparable sales in your neighborhood, photos of property condition issues, repair estimates, or a recent appraisal. Research comparable properties using the county's online assessment portal.
Step 3: Complete Form 130 (Taxpayer's Notice to Initiate an Appeal). Section I and II are for assessment value appeals based on overvaluation. Section III is for objective errors like incorrect property details. State your opinion of value and reasons for appeal.
Step 4: File Form 130 with the DeKalb County Assessor's office by mail, in person, or online through the county portal. Keep a copy for your records and note your filing date.
Step 5: Preliminary Conference - The assessor's office will contact you within 180 days to schedule an informal meeting or phone call to discuss your case. Many appeals are resolved at this stage through stipulation agreement.
Step 6: PTABOA Hearing - If the informal review does not resolve your appeal, your case will be forwarded to the Property Tax Assessment Board of Appeals (PTABOA) for a formal hearing within 180 days of filing. Present your evidence and testimony at the hearing.
Step 7: Appeal to Indiana Board of Tax Review (IBTR) - If you disagree with the PTABOA decision or if they fail to issue a determination within 120 days of the hearing, you may appeal to the state IBTR by filing Form 131 within 45 days of receiving the PTABOA determination.
Step 8: Further Appeals - After IBTR review, you may appeal to the Indiana Tax Court within 45 days, and subsequently to the Indiana Supreme Court if necessary.
