How are property taxes handled when I buy or sell a home?

Property taxes rarely line up neatly with the day you close. Indiana bills taxes in installments through the year, so when a home changes hands mid-cycle, neither side should pay the whole year. The solution at closing is proration: the buyer and seller split the year's taxes so each pays only for the time they actually own the home.

How proration works

The closing statement divides the year at the closing date. The seller is responsible for the taxes covering the portion of the year before closing, and the buyer is responsible for the portion after closing. If the seller already paid an installment that covers part of the buyer's time, the buyer owes the seller a credit at closing. If taxes for the current period are not yet due, the seller typically pays the buyer a credit so the buyer can cover the bill when it arrives. The exact method can vary slightly by county practice, but the principle is the same across Northwest Indiana: each owner pays only their share.

What the closing statement shows

You will see property tax prorations as line items on your closing disclosure or settlement statement, along with the other costs of the transaction. This is where a good agent earns their keep. I review the proration math line by line with clients so no one signs a number they do not understand. My answer on closing costs covers the rest of the money moving at the table, and my guide on closing costs in Northwest Indiana goes deeper.

After closing: escrow and the homestead deduction

For buyers with a mortgage, the lender usually sets up an escrow account and collects property taxes as part of your monthly payment, then pays the county installments when they come due. I explain that rhythm in my answer on when property tax bills are due.

Separately, remember that the seller's homestead deduction ends when the title transfers. As the new owner, you must apply for the homestead deduction on your new primary residence with the county auditor, and the seller's old assessment may also be updated to the sale price. Budgeting for that means the closing table is not the end of the tax story, and my answer on the homestead deduction tells you exactly what to do.

Sellers: make the tax picture clear

If you are selling, buyers will ask about taxes, especially relocating buyers comparing their home state. Pull your current tax bill and any assessment records before listing so we can present an accurate, easy-to-read summary. It builds trust and prevents the "the taxes are higher than I expected" conversation from derailing a deal. You can look up your records using the resources in my answer on finding assessed value and tax bills online, and the neighborhood guides for Schererville, Highland, and Munster help buyers compare communities before they commit.

This is general information rather than tax or legal advice. Proration methods can vary by county and by the language of your purchase agreement, so review your contract and closing statement with your agent and closing professional, and confirm details with the county assessor or treasurer in Lake, Porter, or LaPorte County.
