How to check for unpaid property taxes before closing

Unpaid property taxes are one of the most common last-minute surprises at the closing table. A delinquent balance can stall your loan, force a rushed payoff, or leave you responsible for a bill you never expected. The fix is straightforward: verify the tax status yourself, early, and confirm in writing how the balance will be handled.

Why unpaid taxes block a closing

Title companies generally require all outstanding property taxes to be paid before closing, because a tax lien can attach to the property and take priority over other claims. If taxes are unpaid at the time of sale, the seller is typically debited for their share, and the buyer's share may be collected in escrow. In many transactions, the title company settles these unpaid taxes during closing through tax proration, with the seller compensating for the period they owned the property.

That means an unpaid balance is not automatically fatal — but it must be discovered and resolved before the deed transfers.

Step 1: Find the right county office

Residential property taxes are collected by the county where the property is located, and in some counties the assessor determines the amount owed while the treasurer collects it. Start by identifying the county treasurer or tax collector for the property's address, then use their online search.

Many counties offer a public portal. For example, the City of Virginia Beach Treasurer's Office lets you search real estate tax information by primary owner name, parcel number, or property address, and shows base tax due, penalty, interest, and total due. Similar tools exist in most jurisdictions.

Step 2: Search by parcel number, not just address

Address searches can fail on rural routes, new subdivisions, or properties with multiple parcels. The parcel number — sometimes called a Property Index Number (PIN) — is the reliable identifier. In Cook County, for instance, the Cook County Property Tax Portal lets you search by 14-digit PIN or property address to see a five-year history of billed amounts and tax history.

Use the parcel number from the deed or the seller's tax bill, and pull at least five years of history. A single current-year balance can hide older delinquencies.

Step 3: Check whether taxes were sold or forfeited

In some states, unpaid taxes are sold at an annual tax sale. When owners don't pay, the taxes are sold at the annual tax sale, which occurs at least nine months after the second installment is due. A tax sale creates a lien that a buyer may need to redeem.

Search the county's tax sale records directly. The Cook County Treasurer's Office allows properties with delinquent taxes eligible for sale to be searched by PIN, and the county portal lets you see whether delinquent taxes have been sold or forfeited and whether they were subsequently redeemed.

If a certificate was sold and not redeemed, the payoff amount is not simply the face value of the taxes — it includes penalties and interest. Ask the county for an "estimate of redemption" to find out how much is owed; the county can charge a fee for this information.

Step 4: Understand who pays what at closing

Property taxes are generally prorated between buyer and seller based on the closing date. The common convention is that the seller covers taxes from January 1 up to the closing date, while the buyer becomes responsible for the remaining portion of the year. If the seller has already paid the full year, the buyer reimburses the seller for their prorated share; if taxes are unpaid, the seller is typically debited for their share and the buyer's share may be collected in escrow.

Some states pay taxes in arrears, meaning the bill you pay covers the previous year. In Texas, for example, property taxes are paid in arrears, so a mid-year sale splits the prior year's tax between buyer and seller based on days of ownership. Confirm your state's convention before you assume the standard January-to-December split applies.

Step 5: Get it in writing before closing

Verbal assurances are not enough. Ask for the following in the closing documents:

• A current tax status printout from the county showing the balance due, penalties, and interest.
• A written proration statement showing the seller's share and the buyer's share.
• If a tax sale certificate exists, the redemption amount and who is paying it.
• Confirmation of whether an escrow holdback will cover any unassessed or pending tax bill.

A quick pre-closing checklist

1. Identify the county treasurer or collector for the property.
2. Pull the parcel number from the deed or tax bill.
3. Search the county portal for at least five years of tax history.
4. Check the tax sale list for the parcel.
5. Request an estimate of redemption if a certificate was sold.
6. Confirm the proration method used in your state.
7. Review the settlement statement for the tax line items before you sign.
