Texas Property Tax Proration at Closing

Want to see what you qualify for? I can run your numbers and give you a clear answer quickly.

Texas Property Tax Proration at Closing

Texas property tax proration at closing divides the current year’s property taxes between the seller and buyer based on when each party owns the property.

Because Texas property taxes are generally billed later in the calendar year, a seller may transfer the property before the final tax bill is available.

Instead of waiting for the bill, the title company estimates the seller’s share and usually provides the buyer with a credit at closing.

That credit does not necessarily mean the taxes have been paid.

The buyer may still be responsible for paying the entire tax bill when it becomes due.

Understanding this distinction helps explain:

Why the seller receives a debit
Why the buyer receives a credit
Why the lender still collects an escrow deposit
Why prorations may change after closing
Why the seller’s existing exemptions matter
Why new-construction taxes can be misleading
Why the buyer’s future mortgage payment may be higher than expected

Texas property tax proration is part of the real estate settlement—not the same thing as the lender’s escrow-account calculation.

Texas Property Taxes Are Generally Paid in Arrears

Texas taxing authorities generally begin mailing property tax bills in October.

Payment is due upon receipt, and in most cases taxes must be paid by January 31 of the following year. Taxes generally become delinquent on February 1 if unpaid.

The Texas Comptroller explains the current schedule in its guide to paying Texas property taxes.

This creates a common closing situation.

A seller may own the property from January through June but sell it before the current year’s final tax bill has been issued.

Because the buyer will own the property when the bill arrives, the closing statement typically allocates the seller’s estimated share through a proration credit.

What Is a Property Tax Proration?

A property tax proration is an accounting adjustment between the buyer and seller.

It estimates how much of the current year’s taxes should economically belong to each party based on the closing date.

The calculation generally allocates:

Seller’s share through the closing date
Buyer’s share after the closing date

Under the current Texas Real Estate Commission One to Four Family Residential Contract, current-year taxes are prorated through the closing date. The contract also allows the calculation to consider changes in exemptions and provides for an adjustment when the final tax statements become available. The current form is available through the Texas Real Estate Commission.

The parties’ actual contract controls the closing allocation.

Not every property uses the same TREC form, and the parties can agree to different terms when legally permitted.

How the Seller Credit Works

Assume:

Estimated annual property taxes: $12,000
Closing date: June 30
Seller’s ownership period: 181 days
Calendar year: 365 days

The daily tax amount is:

$12,000 ÷ 365 = $32.88 per day

The estimated seller portion is:

$32.88 × 181 days = approximately $5,950.68

At closing:

The seller may receive a $5,950.68 debit
The buyer may receive a $5,950.68 credit

The buyer then becomes responsible for paying the complete tax bill when due, assuming the taxes were not already paid at closing.

The proration allocates responsibility between the parties. It does not necessarily send the seller’s share directly to the county tax office.

If you want help walking through your specific situation, I can run the numbers with you.

Get Pre-Approved

Is the Closing Date Charged to the Buyer or Seller?

The answer depends on the contract.

The current TREC resale contract provides that current-year taxes are prorated through the closing date.

That generally means the seller’s proration includes the closing date under that contract language.

However, different contracts may use different allocation terms.

Transactions involving:

New construction
Condominiums
Farm and ranch property
Commercial property
Builder contracts
Attorney-drafted contracts
Seller financing

may contain different language.

The title company should follow the executed purchase contract rather than a general assumption.

Why the Seller Usually Gives the Buyer a Credit

The seller occupied or owned the property for part of the year but may not yet have paid the corresponding property taxes.

The buyer will receive the tax bill later because the buyer owns the property when the bill is issued.

The seller credit reimburses the buyer in advance for the seller’s estimated portion.

Without the credit, the buyer could become responsible for the entire annual bill even though the buyer owned the property for only part of the year.

Does the Seller Credit Pay the Property Taxes?

Not always.

The seller’s proration credit is usually a closing adjustment between the parties.

It may reduce the buyer’s cash due at closing, but the taxes may remain unpaid.

The buyer or the buyer’s mortgage servicer will later pay the full tax bill.

The Closing Disclosure or settlement statement should show whether:

Taxes were paid directly at closing
The seller provided only a proration credit
The lender collected escrow reserves
Delinquent taxes were paid
A prior tax installment was reimbursed
A tax holdback was established

These entries should not be treated as interchangeable.

Property Tax Proration Versus the Buyer’s Escrow Account

The seller’s tax credit and the lender’s escrow account serve different purposes.

Seller Tax Proration

The tax proration:

Divides current-year tax responsibility
Is based on the purchase contract
Appears as a buyer credit and seller debit
Usually covers the seller’s ownership period
May be estimated before the final bill exists

Lender Escrow Account

The lender’s escrow account:

Accumulates money for future taxes and insurance
Is governed by mortgage and federal escrow requirements
May require an initial deposit at closing
Is funded through the borrower’s monthly mortgage payment
Is maintained by the mortgage servicer

The lender may still collect several months of property taxes for escrow even when the buyer receives a substantial seller tax credit.

The seller credit can reduce the buyer’s net cash-to-close, but it does not necessarily replace the servicer’s required escrow balance.

Why the Lender Collects Tax Reserves

The lender wants enough money in the escrow account to pay the property taxes when due.

The number of months collected depends on:

Closing date
First mortgage payment date
Expected tax due date
Annual tax estimate
Federal escrow limits
Existing tax payments
Loan program
Servicer requirements

A buyer closing early in the year may see a different escrow deposit from a buyer closing in September or October.

This does not mean one buyer is being taxed more.

It reflects when the servicer expects to collect monthly deposits before the annual tax bill must be paid.

Does the Buyer Receive the Seller Credit as Cash?

Usually not as a separate cash payment.

The credit is generally applied within the closing statement.

It may reduce the amount the buyer must bring for:

Down payment
Closing costs
Prepaid expenses
Escrow deposits
Other settlement charges

The exact impact depends on:

Loan program
Minimum borrower contribution
Interested-party contribution limits
Final closing figures
Treatment by the title company and lender

The credit should not be confused with a negotiated seller concession for closing costs.

It is generally an allocation of taxes between the parties rather than an optional sales incentive.

How the Title Company Estimates the Taxes

If the current year’s tax bill is unavailable, the title company may estimate the proration using:

Previous year’s tax bill
Current assessed value
Current tax rates
Known exemptions
Expected exemption changes
County tax records
Contract instructions
Tax certificates
New-construction information

The estimate may not match the eventual tax bill.

Differences can occur because of:

Higher assessed value
New tax rates
Lost exemptions
New exemptions
Completed construction
Supplemental assessments
Corrected appraisal rolls
Property splits or combinations
Special district taxes
Disabled-veteran eligibility
Agricultural appraisal changes

The contract determines whether and how the parties must reconcile the difference later.

Re-Proration After the Final Tax Bill

The current TREC resale contract provides that if the current year’s taxes differ from the amount prorated at closing, the parties will adjust the proration when the actual tax statements become available.

This is commonly called:

Re-proration
Post-closing tax adjustment
Tax reconciliation
Final tax proration

Suppose the title company estimated annual taxes at $10,000, but the final bill is $11,200.

The seller’s actual share would be higher than the amount credited at closing.

Under the applicable contract, the seller may owe the buyer an additional amount.

If the final bill is lower, the buyer may owe part of the difference back to the seller.

The title company does not necessarily manage or enforce every post-closing adjustment. The buyer and seller may need to coordinate directly.

Example of a Post-Closing Adjustment

Assume:

Closing date: September 30
Seller days: 273
Estimated annual taxes: $9,000
Actual annual taxes: $10,500

Estimated seller share:

$9,000 ÷ 365 × 273 = approximately $6,731.51

Actual seller share:

$10,500 ÷ 365 × 273 = approximately $7,853.42

Difference:

$7,853.42 − $6,731.51 = approximately $1,121.91

The seller may owe the buyer approximately $1,121.91, subject to the contract and the final calculation.

Why Exemptions Matter

The seller and buyer may qualify for different property-tax exemptions.

Potential exemptions include:

General residence homestead exemption
Over-65 exemption
Disabled-person exemption
Disabled-veteran exemption
Surviving-spouse exemption
Local-option exemptions
Agricultural or open-space appraisal

The seller’s current tax bill may be unusually low because of exemptions the buyer will not retain.

The TREC contract allows the tax proration calculation to consider changes in exemptions that will affect current-year taxes.

The Texas Comptroller provides current information about Texas property-tax exemptions.

The Seller’s Homestead Exemption May Not Transfer

A general residence homestead exemption is tied to the qualifying owner and occupancy.

The buyer must generally establish their own eligibility and file the appropriate application.

A buyer should not assume that the seller’s:

Homestead exemption
Appraisal cap
Over-65 tax ceiling
Disabled-veteran exemption
Surviving-spouse exemption

will transfer automatically.

Some exemptions may apply for part of the year, while others involve more complicated qualification or tax-ceiling rules.

The county appraisal district determines exemption eligibility.

Disabled Veteran Exemption Example

Suppose the seller is a qualifying veteran receiving a total residence-homestead exemption.

The property’s current tax bill may be close to zero.

The buyer does not qualify for the same exemption.

If closing documents simply use the seller’s current tax bill, the proration and buyer’s future payment could be severely understated.

The title company and lender may need to estimate taxes without the seller’s exemption.

This protects the buyer from an unrealistic closing estimate and helps the lender calculate an accurate future mortgage payment.

Over-65 Exemptions and Tax Ceilings

A seller age 65 or older may benefit from:

Additional exemptions
School-district tax ceiling
Local tax limitations
Deferred taxes

Those benefits do not necessarily transfer to a younger buyer.

The buyer’s future tax bill may be significantly higher than the seller’s.

A lender should not use the seller’s tax ceiling as the buyer’s permanent tax estimate unless the buyer independently qualifies.

This is one reason Why Are Mortgage Payments Higher Than Expected? can become relevant after closing.

Homestead Appraisal Cap

A Texas residence homestead may benefit from limitations on annual increases in taxable appraised value.

When the property changes ownership, the prior owner’s capped taxable value may not continue in the same way for the buyer.

The county appraisal district may later reassess the property based on applicable law.

That can create a future tax increase even when:

The tax rate remains unchanged
The buyer files a new homestead exemption
The seller’s last tax bill was low
The lender originally estimated taxes from public records

The buyer should review both:

Current tax bill
Potential future assessed value

New-Construction Property Tax Proration

New construction creates some of the largest property-tax surprises.

The current tax records may reflect only:

Vacant land
Partially completed construction
A builder-owned parcel
An incomplete improvement value
A larger parent tract
No individual lot assessment

The final tax bill after completion may be much higher.

For example:

Current land-only taxes: $1,500
Expected completed-home taxes: $9,500

A builder contract might prorate taxes using the current land-only amount, while the lender qualifies the buyer using the projected completed-home taxes.

Those are different calculations serving different purposes.

The buyer should review:

Builder contract
Preliminary Closing Disclosure
County appraisal records
Estimated completed value
Tax rates
Planned escrow collection

A low seller proration does not guarantee a low future property-tax bill.

Builder Contracts May Use Different Rules

The standard TREC resale contract is not intended for every new-construction transaction.

Builders often use proprietary contracts.

A builder contract may:

Use the previous year’s taxes
Use land-only taxes
Limit post-closing re-proration
Make the buyer responsible for supplemental taxes
Establish a specific proration method
Include special district assessments
Allocate rollback taxes separately

The buyer should read the builder’s tax-proration provision rather than assuming the resale-contract rules apply.

Property Purchased Early in the Year

If a buyer closes early in the year, the current tax bill may not yet exist.

The title company will likely estimate the seller’s short ownership period.

For example, with $12,000 in annual estimated taxes and a February 28 closing:

Seller days in a non-leap year: 59
Daily taxes: approximately $32.88
Seller credit: approximately $1,939.73

The buyer will own the property for most of the year and will ultimately bear most of the tax cost.

Property Purchased Late in the Year

A late-year closing may occur after tax bills have been issued.

The title company may:

Pay the full bill at closing
Credit one party for taxes already paid
Prorate the paid amount between the parties
Require the seller to satisfy unpaid taxes
Coordinate payment with the buyer’s lender or servicer

If taxes have already been paid by the seller, the settlement may show a buyer debit reimbursing the seller for the buyer’s portion.

This is the reverse of the more familiar seller-credit scenario.

What If the Seller Already Paid the Taxes?

If the seller paid the full current-year tax bill before closing, the buyer may owe the seller for the buyer’s share after the closing date.

For example:

Annual taxes already paid: $12,000
Closing date: September 30
Buyer’s portion: October 1 through December 31
Buyer days: 92

Buyer’s reimbursement:

$12,000 ÷ 365 × 92 = approximately $3,024.66

The settlement statement may show:

Buyer debit: $3,024.66
Seller credit: $3,024.66

The taxes have already been paid to the taxing authorities, so the allocation reimburses the seller.

What If the Current Taxes Are Unpaid?

Under the current TREC resale contract, if current-year taxes are not paid at or before closing, the buyer is responsible for paying the current year’s taxes.

The seller’s proration credit is designed to compensate the buyer for the seller’s share.

The title company still must verify that prior delinquent taxes are addressed.

A buyer cannot obtain clear title while delinquent property-tax liens remain unresolved.

Delinquent Property Taxes

Texas property taxes generally become delinquent on February 1 when not timely paid, subject to exceptions involving late-issued bills.

Penalties and interest can accrue.

A tax lien automatically attaches to taxable property on January 1 to secure that year’s taxes, according to the Texas Comptroller.

At closing, delinquent property taxes may need to be:

Paid from seller proceeds
Paid through the refinance
Resolved through an approved arrangement
Addressed as a title condition

A seller credit for current-year proration does not resolve prior-year delinquent taxes.

Who Is Legally Liable for the Taxes?

The Texas Comptroller states that a person who owns taxable property on January 1 is liable for the taxes due for that year.

The tax lien also attaches to the property, which means unpaid taxes can affect the property after ownership changes.

This is why the title company:

Verifies tax status
Requires delinquent taxes to be paid
Obtains tax certificates or statements
Allocates current-year taxes through the contract
Protects the lender’s lien position

The seller’s personal liability and the property’s tax lien are related but distinct from the contractual proration between buyer and seller.

Proration Does Not Change the Taxing Authority’s Records

The county tax office does not generally divide the annual bill according to the buyer’s closing statement.

The taxing authority issues the bill according to its records and collection procedures.

The buyer and seller’s proration is a private contractual allocation.

If the final bill differs, the taxing authority usually expects the full amount regardless of whether one party refuses to honor a re-proration obligation.

The Lender’s Property Tax Estimate

The lender must calculate property taxes when determining the borrower’s proposed housing payment.

That calculation can affect:

Debt-to-income ratio
Maximum loan amount
Cash-to-close
Initial escrow deposit
Monthly mortgage payment
Automated underwriting

The lender may use:

Current tax bill
Tax certificate
County records
Applicable tax rates
Projected assessment
Known exemption changes
New-construction estimate

The lender’s underwriting estimate may differ from the title company’s contractual proration.

That does not automatically mean either calculation is wrong.

They may be answering different questions.

Example of Different Closing and Underwriting Calculations

Suppose:

Seller’s current annual taxes: $4,000
Seller has an over-65 exemption and tax ceiling
Buyer’s estimated annual taxes: $10,000

The title company may calculate the seller’s proration using an adjusted estimate based on the contract’s exemption-change provision.

The lender may use $10,000 to calculate the buyer’s future monthly payment:

$10,000 ÷ 12 = $833.33 per month

Using the seller’s $4,000 bill would produce only:

$4,000 ÷ 12 = $333.33 per month

That $500 monthly difference could materially affect mortgage qualification.

Tax Proration and Seller Concessions

A property-tax proration is generally separate from a negotiated seller concession.

Seller concessions may be used for eligible buyer costs, subject to loan-program limits.

Tax proration compensates the buyer for the seller’s estimated share of taxes.

The Closing Disclosure may show both:

Seller concession
Property-tax adjustment

The lender should not automatically combine them when testing interested-party contribution limits.

However, unusual tax credits or amounts exceeding a reasonable proration may receive additional scrutiny.

Tax Proration and Cash-to-Close

A seller tax credit can reduce the buyer’s net cash required at closing.

For example:

Down payment and costs: $45,000
Seller tax-proration credit: $6,000
Other credits: $2,000

Estimated buyer cash:

$45,000 − $6,000 − $2,000 = $37,000

The final Closing Disclosure controls.

The buyer should not spend the tax credit after closing because the annual tax obligation still exists.

If the mortgage has no escrow account, the buyer may need to preserve the credit for the tax bill.

What If the Buyer Waives Escrow?

When permitted by the loan program and lender, a borrower may pay property taxes directly instead of maintaining an escrow account.

The buyer then becomes responsible for:

Monitoring tax bills
Paying each taxing unit
Meeting the January deadline
Maintaining sufficient reserves
Addressing supplemental bills
Confirming exemption changes

The seller’s tax credit should be treated as money allocated toward the upcoming tax obligation—not free cash.

Failure to receive the bill generally does not eliminate the tax, penalty, interest, or lien.

Refinances Do Not Have a Seller Tax Proration

A refinance does not transfer ownership from a seller to a buyer.

Therefore, there is generally no seller tax-proration credit.

The new lender may still:

Pay delinquent taxes
Collect an initial escrow deposit
Refund an old escrow account after payoff
Require taxes due soon to be paid at closing
Verify exemptions
Recalculate future taxes

The borrower may temporarily see both:

New escrow funding at closing
Old escrow funds still held by the prior servicer

The prior servicer typically issues the remaining escrow refund separately after the mortgage payoff is processed.

Tax Proration in an Assumption

A mortgage assumption and property purchase can still involve property-tax proration between seller and buyer.

The existing mortgage escrow account does not automatically determine the contractual tax allocation.

The servicer, title company, seller, buyer, and assumption documents must address:

Existing escrow balance
Current-year tax responsibility
Paid or unpaid taxes
Required escrow transfer
Settlement credits

The assumption should not proceed based solely on the seller’s current monthly payment.

Special Assessments and Other Prorated Charges

The TREC contract’s proration paragraph can also address items such as:

Interest
Rents
Regular maintenance fees
Assessments
Association dues
Prepaid items

These are separate from property taxes but may appear in the same section of the settlement statement.

Public improvement district assessments, municipal utility district charges, HOA assessments, and other obligations may require additional review.

Not every charge follows the same proration method.

Multiple Taxing Authorities

A Texas tax bill may include charges from several taxing units, such as:

County
City
School district
Hospital district
Community college district
Emergency services district
Municipal utility district
Other special district

Some counties issue a consolidated bill.

Others may have separate collection offices.

The title company should verify every applicable taxing unit rather than relying on only one county record.

Multiple Parcels

A property composed of multiple parcels may have several tax-account numbers.

The title company and lender must confirm:

Every parcel included in the sale
Taxes for each parcel
Delinquent balances
Current exemptions
Whether parcels were recently split
Whether the residence crosses parcel lines
Whether the tax proration includes the complete property

Missing a parcel can produce an incomplete tax estimate or unresolved tax lien.

Related issues appear in Buying a Property With Multiple Parcels.

Questions Worth Asking Before Closing

Before accepting the Texas property tax proration at closing, ask:

What annual tax amount was used?
Is that amount estimated or final?
Which exemptions does the seller currently receive?
Will the buyer qualify for the same exemptions?
Does the calculation include all taxing authorities?
Does it include every parcel?
How many seller days were used?
Does the contract prorate through the closing date?
Have current taxes already been paid?
Are any taxes delinquent?
Will the lender maintain an escrow account?
How much initial escrow will be collected?
Could the parties need to re-prorate after closing?
Is the property new construction?
Is the current tax bill based only on land?
Are special assessments included?
What future annual tax amount did the lender use for qualification?

These questions can explain significant differences in the final cash-to-close.

Common Misconceptions

“The Seller Pays Their Taxes Directly at Closing”

Sometimes taxes are paid at closing.

Other times, the seller provides a credit and the buyer later pays the full bill.

The settlement statement shows which method applies.

“The Seller Tax Credit Is Free Money”

The credit represents the seller’s estimated share of an upcoming tax bill.

The buyer will generally remain responsible for the full bill when due.

“The Tax Credit Replaces My Escrow Deposit”

The seller credit and lender escrow account are separate calculations.

The lender may still collect an initial escrow reserve.

“The Seller’s Tax Bill Will Become My Tax Bill”

The seller may have exemptions, tax ceilings, or capped values that do not transfer.

The buyer’s future taxes can be substantially higher.

“The Proration Is Always Final”

If the final tax bill differs from the estimate, the purchase contract may require the parties to adjust the proration after closing.

“The County Splits the Bill Between Buyer and Seller”

The proration is generally a contractual allocation.

The taxing authority expects payment of the full bill.

“New-Construction Taxes Are Low”

Current records may reflect only the land or partial construction.

The completed property’s future taxes may be much higher.

Real Scenarios We Encounter

The Seller Has a 100% Disabled Veteran Exemption

The current tax bill is zero or extremely low.

The buyer does not qualify for that exemption.

The title company and lender must avoid using zero taxes as the buyer’s permanent estimate.

The Seller Is Over 65

The seller benefits from an additional exemption and school-tax ceiling.

The buyer is younger and does not qualify.

The lender calculates a higher future payment, and the proration may consider the exemption change.

The New Home Is Taxed as Vacant Land

The builder’s current tax bill reflects only the lot.

The purchase contract provides a small seller proration, while the lender escrows based on projected taxes for the completed home.

The buyer must plan for the higher future bill.

Taxes Were Already Paid Before a December Closing

The seller paid the entire annual tax bill.

The buyer reimburses the seller for the buyer’s portion through a debit on the settlement statement.

The Final Bill Is Higher Than the Estimate

The title company prorated taxes using the prior year’s bill.

The county later issues a higher bill.

The buyer asks the seller to complete the post-closing adjustment required by their contract.

A Parcel Was Omitted

The property includes the house parcel and a separate driveway parcel.

The initial proration includes only the house.

The title company must correct the settlement calculation and verify taxes on both parcels.

Real Lender Perspective

Property tax proration becomes confusing because three different calculations can appear in the same transaction:

The seller and buyer’s contractual proration
The lender’s future monthly tax estimate
The lender’s initial escrow deposit

Those numbers do not have to match.

For example, the seller may receive a debit based on the seller’s actual exemptions, while the lender qualifies the buyer using higher projected taxes and collects enough escrow to pay the future bill.

The strongest review asks:

What taxes are being allocated?
What taxes are being used for qualification?
What taxes are being collected for escrow?
What exemptions will change?
Who will pay the actual bill?

When those questions are answered separately, the Closing Disclosure becomes much easier to understand.

Who This Guide Is For

This guide may be especially helpful for:

Texas homebuyers
Texas home sellers
First-time homebuyers
Buyers closing late in the year
New-construction buyers
Veterans purchasing from exempt sellers
Buyers purchasing from sellers over age 65
Borrowers waiving escrow
Buyers of multiple-parcel properties
Real estate agents
Title professionals
Buyers whose cash-to-close changed unexpectedly

Final Thoughts

Texas property tax proration at closing is an accounting adjustment between the buyer and seller.

When current-year taxes have not been paid:

The seller generally credits the buyer for the seller’s ownership period
The buyer usually becomes responsible for the complete tax bill
The lender may separately collect an escrow deposit
The parties may need to adjust the proration after the final bill is issued

The seller’s tax credit, buyer’s monthly tax estimate, and lender’s escrow deposit are separate calculations.

The most significant surprises occur when:

The seller has exemptions the buyer will not receive
The property is new construction
The taxable value is capped
Multiple parcels are involved
The annual tax estimate increases
The buyer assumes the credit represents taxes already paid

Reviewing the tax bill, exemptions, contract, Closing Disclosure, and lender escrow calculation before closing can prevent both cash-to-close surprises and a larger-than-expected mortgage payment later.
