Tippecanoe County Property Tax: Due Dates, Deductions & Appeals

Property taxes in Tippecanoe County are billed in two installments each year, with the 2026 due dates falling on May 11 and November 10.¹ Three county offices handle the work behind that bill: the Assessor sets your property’s value, the Auditor applies deductions and calculates the rate, and the Treasurer collects what you owe.² Miss a deadline and the penalty starts at 5%.

When Payments Are Due and How To Pay

Tax bills are mailed once a year, typically in mid-April, and include coupons for both installments. For 2026, the spring installment is due May 11 and the fall installment is due November 10.¹

The Treasurer accepts payment through a secure online portal using credit cards or electronic checks. Credit card payments carry a convenience fee that typically runs between 2% and 5% of the amount paid. You can also mail a check with your payment coupon to the county courthouse or drop off payment at a designated local bank branch.³ Keep the receipt or confirmation number whichever way you pay.

What Happens If You Pay Late

Missing a due date triggers an immediate penalty. If you pay in full within 30 days of the deadline and have no prior delinquencies on the same parcel, the penalty is 5% of the unpaid amount. If you already owe any back taxes or penalties on that parcel, the penalty is 10%.⁴

It gets worse the longer the balance sits. Each year after the initial delinquency, another 10% is added to any remaining unpaid principal the day after each installment date. The added penalties apply only to the original unpaid tax, not to earlier penalties, but a two-year delay can still add roughly 30% to the bill.⁴

How Your Bill Is Calculated

The Assessor values every parcel in the county using mass appraisal. Under Indiana law, each assessment must reflect the property’s “true tax value,” which generally means its market value based on current use.⁵ After the Assessor finalizes a value, you receive a Form 11 (Notice of Assessment of Land and Improvements) showing the current and prior-year figures and instructions for appealing.⁶ Keep that form; the figures on it feed every deduction application and any appeal.

Indiana’s Property Tax Caps

Indiana’s constitution limits how much property tax you can owe compared to your property’s gross assessed value. If the calculated bill exceeds the cap, the Auditor automatically applies a credit that pulls it back down. The caps are:⁷

1% of gross assessed value for owner-occupied homestead property
2% for other residential property and agricultural land
3% for all other real and personal property

One exception matters: voter-approved referendum projects, such as school construction bonds or extra operating funds, are exempt from the caps. If your school corporation or municipality passed a referendum, those charges sit on top of the cap on your bill.⁷

Deductions That Lower What You Owe

Several deductions can reduce your assessed value before the tax rate is applied, but none of them are automatic. You apply through the Tippecanoe County Auditor’s office, either in person at the county building or through the online portal on the Indiana Department of Local Government Finance website.² To have a deduction appear on your next tax bill, file on or before January 5 of the year the taxes are first due and payable. Filing by January 5, 2026 means the deduction applies to your 2026 bills; miss that date and the benefit shifts to the following year.⁸

Most deductions only need to be filed once and carry forward each year, but the Auditor can revoke a deduction if you no longer qualify, so keep residency and income documentation current. Save your online confirmation code, or ask for a stamped copy when filing in person.

Homestead Standard and Supplemental Deductions

The standard homestead deduction cuts your assessed value by the lesser of 60% or $48,000. The property must be your primary residence, and you generally need a driver’s license or state ID showing the property address. Once the standard deduction applies, the supplemental homestead deduction kicks in automatically. For taxes due in 2026, the supplemental removes an additional 40% of the remaining assessed value after the standard deduction, and the total supplemental cannot exceed 75% of the property’s gross assessed value.⁹

Over 65 Credit

Homeowners aged 65 or older may qualify for a $150 property tax credit on their 2026 bills. Adjusted gross income cannot exceed $60,000 for individual filers or $70,000 for married joint filers. Bring proof of age and prior-year income documentation when you apply.

Blind or Disabled Person Deduction

Residents with qualifying vision impairments or permanent disabilities can apply for an additional deduction. The Auditor’s office typically requires a physician’s statement or a Social Security award letter. Contact the office directly for current amounts and eligibility details.

Disabled Veteran Deductions

Indiana offers two deductions for disabled veterans, and a qualifying veteran can claim both. A veteran with a service-connected VA disability rating of at least 10% who served during a recognized wartime period may deduct $24,960 from the assessed value of a primary residence. A separate $14,000 deduction is available to veterans who served at least 90 days and are either totally disabled or over 62 with at least a 10% VA rating, as long as the home’s assessed value is under $240,000. Together, that totals $38,960. Surviving spouses of eligible veterans also qualify.¹⁰

Mortgage Deduction (Repealed)

Older guidance sometimes mentions an Indiana mortgage deduction. The legislature repealed it effective January 1, 2023. It no longer appears on Tippecanoe County tax bills, and no application is accepted.

If a Mortgage Lender Pays Through Escrow

If you have a mortgage, your lender likely collects property taxes through an escrow account built into your monthly payment. The lender estimates the annual tax and insurance costs, divides by 12, and pays the Treasurer directly when each installment comes due.

Each year the lender runs an escrow analysis comparing what was collected to what was actually owed. If your assessed value or the local rate went up, the account may come up short and your monthly payment will rise to cover the gap. You can usually pay the shortage in a lump sum to keep the monthly amount lower, or let the lender spread it over the next 12 months.

Even with escrow, you remain responsible for making sure the taxes are paid. Verify each year that the payment actually posted by checking the Treasurer’s online portal or calling the office. Escrow does not always cover supplemental tax bills or special assessments, which can arrive separately and require direct payment.

Appealing an Assessment You Believe Is Too High

If the assessed value on your Form 11 looks too high, file a Form 130 (Taxpayer’s Notice to Initiate an Appeal) with the Tippecanoe County Assessor. The deadline depends on when the Form 11 was mailed. If it went out before May 1 of the assessment year, you must file by June 15 of that year. If it was mailed on or after May 1, your deadline extends to June 15 of the year the tax statement is mailed.¹¹ Waiting for the actual tax bill is risky; the deadline may already have passed.

After filing, the Assessor’s office schedules an informal conference to review your property’s record card. Errors in square footage, bathroom count, or whether a basement is listed as finished are the most common items resolved at this stage. If no agreement comes out of the conference, the case moves to the county’s Property Tax Assessment Board of Appeals (PTABOA) for a formal hearing.¹²

At the PTABOA hearing, both sides present evidence. The strongest cases rely on recent comparable sales showing similar homes sold for less than your assessed value, or on an independent appraisal from a certified residential appraiser. A professional appraisal typically costs between $575 and $1,300, so weigh that against potential tax savings over several years. If the PTABOA denies the appeal, you can escalate to the Indiana Board of Tax Review and then the Indiana Tax Court.¹²

When Unpaid Taxes Lead to a Tax Sale

If a property falls at least three installments behind with a combined delinquency of $25 or more, it becomes eligible for a tax sale under Indiana Code 6-1.1-24. The county sells a lien on the property to a third-party buyer. The owner then has a limited window to redeem the property by paying all back taxes, penalties, and costs. Failing to redeem within that window can let the buyer obtain a tax deed and take ownership of the property. It is the most severe consequence of ignoring a tax bill, and it happens more often than most homeowners expect.
