How Property Tax Works

Brown County, Indiana operates under a property tax system that funds essential local services including schools, public safety, infrastructure, and county government operations. Property taxes are calculated based on the assessed value of your property multiplied by the applicable tax rate, which varies by location within the county due to different special taxing districts such as school corporations, library districts, and fire departments.

For the 2025-2026 fiscal year, Brown County has adopted a total tax rate of 0.49482%, which is significantly lower than Indiana's typical base rate of around 1%. However, your actual tax rate may differ depending on which special taxing districts serve your specific property location within the county. The county uses a market value-in-use assessment approach, with properties typically reassessed on a cyclical basis to ensure fair and equitable taxation across all property owners.

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.

Supplemental Tax Bills

Supplemental taxes in Brown County are additional property tax bills issued when there are changes to property ownership, value, or assessment during the tax year. Common triggers include new construction, major improvements, ownership transfers, or corrections to the original assessment. These supplemental bills are calculated based on the difference between the old and new assessed values, multiplied by the applicable tax rate, and prorated for the portion of the tax year affected.

For example, if you complete a $50,000 home addition in March and your total tax rate is 0.75%, you would receive a supplemental bill for approximately $375 ($50,000 × 0.0075) prorated for the remaining months of the tax year. Supplemental tax bills are issued as changes are processed and have separate due dates from your regular property tax installments, typically 30 days from the date of issuance.

Escrow & Property Taxes

Most mortgage lenders in Brown County require property tax escrow accounts for borrowers with less than 20% equity. Your lender collects monthly escrow payments along with your mortgage payment, typically 1/12th of your estimated annual tax bill. The lender holds these funds in a separate account and pays your property tax bills directly to the Brown County Treasurer when due.

Lenders must provide annual escrow analysis statements showing the account balance, payments made, and any adjustments needed. If your taxes increase, your monthly escrow payment will be adjusted accordingly. You should verify that your lender pays both installments on time (first installment due January 31st, second installment due July 31th for the current tax year) to avoid penalties. If you pay taxes directly without escrow, you're responsible for meeting these deadlines and can make payments online through the Brown County Treasurer's website or in person at the county offices.
