How Property Tax Works

Property taxes in Posey County, Indiana fund essential local services including schools, law enforcement, fire protection, roads, and county government operations. The county operates under Indiana's property tax system where taxes are calculated based on assessed value multiplied by local tax rates. For the 2025 tax year, Posey County's base property tax rate is 0.0060530 (approximately 0.61%), though this represents only a portion of the total tax bill.

Property tax rates vary significantly by location within Posey County due to special taxing districts including school corporations, townships, libraries, fire districts, and tax increment financing (TIF) areas. The total effective tax rate typically ranges from 1.5% to 2.5% of assessed value depending on your specific location and applicable special districts. Property is assessed at 100% of true market value, with assessments updated annually by the Posey County Assessor's Office.

Section 4

Supplemental Tax Bills

Supplemental property taxes are additional assessments that occur when property changes ownership, undergoes new construction, or receives improvements that increase its assessed value mid-tax year. These taxes cover the period from when the change occurred until the end of the current tax year. The supplemental tax is calculated by applying the current tax rate to the difference between the old and new assessed values, prorated for the remaining months in the tax year.

For example, if you purchase a home in Posey County in July that was previously assessed at $200,000 but now has a market value of $250,000, you would receive a supplemental tax bill for the $50,000 increase in assessed value, multiplied by your area's tax rate, multiplied by 6/12 months (July through December). This supplemental bill is separate from the regular property tax bill and typically arrives 4-8 weeks after the assessment change is processed.

Escrow & Property Taxes

Most mortgage lenders in Posey County require property tax escrow accounts to ensure timely payment of property taxes. Your lender collects 1/12 of your estimated annual property tax bill each month along with your mortgage payment. The lender maintains these funds in an escrow account and pays your property taxes directly to Posey County when due. Property taxes in Posey County are paid in two installments: the first installment is due May 11, 2026, and the second installment is due November 10, 2026, with a final deadline of December 31, 2026.

Lenders typically review and adjust escrow accounts annually based on actual tax bills and assessment changes. If your property taxes increase due to rising assessments or rate changes, your monthly escrow payment will be adjusted accordingly. You should receive an annual escrow analysis from your lender showing the account activity and any required payment changes. Property owners can verify tax payments and balances through the Posey County Treasurer's online portal or by contacting the office directly.
