An Indiana closing can involve both a property-tax bill already issued and taxes assessed but not yet billed. Understanding the state's payment calendar helps explain why the settlement figure may differ from a simple share of the current bill.
What paying in arrears means
Yes. The Department of Local Government Finance says it plainly: property taxes in Indiana are paid in arrears and are typically due annually in two installments, May 10 and November 10.
Arrears is the term used when taxes paid in the current year represent the taxes owed for the previous year.
The assessment date is the other half
The lag is built in at the front end. The state's 2026 assessment calendar lists January 1 as the real property and personal property assessment date for taxes due and payable in 2027, under Indiana Code 6-1.1-2-1.5. So the condition and value of a house on New Year's Day of one year produces a bill in the next one.
Which means that on the day you sell, two tax years are in play at once. One has been billed and is being paid off in installments. The next has already been assessed and has not been billed.
The two installments, as the state printed them this year
The same calendar gives the 2026 dates: the first installment of 2025 pay 2026 property taxes due May 11, and the second installment of 2025 pay 2026 taxes due November 10, both under Indiana Code 6-1.1-22-9. Note the May date. The customary date is the tenth, and it moves when the tenth lands on a weekend, which is why it was the eleventh this year.
Check the published due date for the relevant bill rather than assume the customary date applies.
What it does to a closing
It is the reason the property tax line on a settlement statement is almost never a simple split of the year. The bills in play do not cover the period either party owned the house, so the contract has to say who carries which installment, and the closing agent does the arithmetic from there. Two closings a month apart, in the same county, on the same purchase price, can show very different tax numbers, and both can be correct.
This is also why I would rather a seller bring the actual tax bill to the listing appointment than tell me from memory what the taxes run. The bill carries the pay year on its face. A number from memory usually carries the wrong one.
Where the deductions sit in this
The same lag governs the benefits attached to a house. A deduction or credit is tied to an assessment date, not to the day you move, so the question of what carries forward after a sale is a question about which January 1 you held the property on. I have written separately on whether you have to file the homestead deduction again when you move and on whether Indiana's over 65 property tax benefits survive a move, and both turn on this same calendar.
Review the property-tax line before closing using the bill and the agreement's allocation. Explaining the amount at that stage gives the seller time to raise questions with the closing agent.
What your bill will be, how your contract allocates the installments, whether a deduction applies to you, and what the assessor did with your parcel are not mine. Those belong to your county treasurer and auditor, to the closing agent and to your attorney or CPA. I will tell you which office owns the question, and I am not going to quote you a tax figure I have not read off your bill.
The note on what closing costs are and who pays them covers the rest of the money at the table, and the sellers page sets out how a listing is prepared.
