Property Tax Due Dates in Indiana

Indiana property taxes are administered at the county level. Property is assessed at 100% of market value (called "true tax value") as of January 1 each year. Indiana has a unique property tax cap system established by constitutional amendment: property taxes on homesteads are capped at 1% of assessed value, other residential at 2%, and commercial/industrial at 3%. This circuit breaker provides a guaranteed ceiling on tax liability. Tax bills are issued twice a year and cover taxes from the prior year — Indiana taxes are paid one year in arrears.

Indiana property taxes are paid in two equal installments for the prior tax year: First installment: Due May 10 Second installment: Due November 10 A 5% penalty applies if paid within 30 days after the due date; 10% after that. Most counties offer online payment. Contact your county treasurer for payment options. Indiana's property tax cap means no homeowner should pay more than 1% of their home's assessed value in property taxes. If your bill exceeds that threshold, a circuit breaker credit is automatically applied.

Indiana offers significant deductions that reduce assessed value: Homestead Deduction — Owner-occupied primary residences receive a deduction of 60% of the gross assessed value, up to a maximum of $45,000. Additionally, a Supplemental Homestead Deduction of 35% applies to the remaining assessed value up to $600,000, and 25% above that. Combined, these deductions dramatically reduce the taxable value for most homeowners. Mortgage Deduction — Homeowners with a mortgage may deduct up to $3,000 of assessed value. Over-65 Deduction — Homeowners 65 or older with adjusted gross income under $30,000 and assessed value under $240,000 may receive an additional deduction of up to $14,000. Disabled Veteran Deduction — Various deductions ranging from $12,480 to full exemption for 100% disabled veterans.

Indiana property tax appeals are filed with the county assessor: Deadline: File a written notice of appeal with the county assessor within 45 days of the date the tax bill is mailed (typically around April 15 for the first installment). Process: The county Property Tax Assessment Board of Appeals (PTABOA) hears disputes. Present comparable sales or other evidence. PTABOA must issue a decision within 180 days. Further appeal: Appeal PTABOA decisions to the Indiana Board of Tax Review within 45 days, and then to the Indiana Tax Court.
