About Property Taxes 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.
Payment & Assessment
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.
