Property Taxes at Closing: Understanding Prorations When You Buy or Sell a Home
If you’ve bought or sold a home in Texas, you’ve likely seen a line item on your closing statement related to property tax ‘prorations’ — and it can be confusing, especially given how Texas property taxes work on a calendar-year, paid-in-arrears basis. Here’s what’s actually happening. For expert advice and loan quotes related to property taxes, contact American Finance and Investment Co., Inc. (AFIC).
The Core Issue: Taxes Are Assessed for the Whole Year, But Ownership Changes Mid-Year
As discussed in our property tax calendar article, property taxes for a given year reflect ownership/value as of January 1st of that year, but the bill is generally due by the following January 31st. If a property sells partway through the year, someone needs to account for the fact that the eventual tax bill covers a period during which both the seller and buyer owned the property for portions of it.
The General Solution: A Proration Credit at Closing
To address this, closings generally include a proration: the seller provides the buyer with a credit (reducing what the buyer pays, or increasing what the seller receives less, depending on how it’s structured) representing the seller’s share of the year’s property taxes — covering the period from January 1st through the closing date. The buyer then becomes responsible for paying the full year’s tax bill when it comes due, having effectively been reimbursed for the seller’s portion through this credit.
This Is a Credit, Not an Actual Payment to the Tax Office
It’s important to understand: this proration is a financial adjustment between buyer and seller as part of the purchase transaction — it’s not a payment made to the appraisal district or tax office at that time. The actual tax bill is still paid (by whoever owns the property and however their tax payment is set up — directly or through escrow) when it’s due, typically by the following January 31st.
How the Proration Is Calculated
Generally, the proration is based on:
- The estimated or most recent known annual tax amount for the property (since the actual bill for the current year may not yet be available, especially for sales earlier in the year before appraisal notices are issued)
- The portion of the year each party owned the property (calculated to the closing date)
Specific calculation conventions (360-day vs. 365-day year, etc.) can vary slightly by title company or local custom — your closing documents will show the specific calculation used for your transaction.
Why Estimates Matter Here
Since the actual tax bill for the current year often isn’t finalized at the time of a sale (particularly for sales that close before the fall, when bills are typically issued), prorations are often based on the prior year’s tax amount or an estimate — which means the proration might not exactly match what the actual bill turns out to be. This is generally accepted as a normal part of the process, though some closings include provisions for later adjustment if the actual bill differs significantly from the estimate.
What This Means for Buyers
As a buyer, the proration credit you receive at closing is meant to offset the portion of the upcoming tax bill that relates to the seller’s period of ownership — but you (or your escrow account, if applicable) will be responsible for paying the full tax bill when it’s due. Don’t think of the proration credit as ‘extra money’ separate from your tax obligation — it’s specifically there to help cover that obligation.
What This Means for Sellers
As a seller, the proration credit you provide reflects your fair share of taxes for the period you owned the property — even though you won’t be the one writing the check to the tax office (since you no longer own the property when the bill comes due).
New Construction and Prorations
For newly constructed homes, prorations can be particularly tricky, since the property may not have an established tax history, or the land-only value (pre-construction) might be very different from the eventual completed-home value — closing professionals handling new construction transactions are generally familiar with these complexities.
If You Have Questions About Your Specific Closing
Title companies and closing agents handle these calculations as a routine part of their work — if you have questions about how the proration on your specific closing statement was calculated, asking them directly (during the transaction, when they can explain the line items) is the most direct path to understanding your specific numbers.
