Yes, you can sign a sale of Philippine land even if the real property tax is unpaid, but the unpaid tax is a serious problem that usually stops the buyer from getting a clean transfer of title. In practice, the Register of Deeds will require proof that real property taxes are fully paid before issuing a new title, and the unpaid tax remains a lien on the property until settled. That means the real question is not only “Can I sell?” but “Can the buyer safely register the sale and receive a clean title?”

The Short Answer: Yes, But the Tax Must Usually Be Settled Before Transfer

A landowner may enter into a deed of sale even if there are unpaid real property taxes, also called RPT or amilyar. A contract of sale is formed when the seller agrees to transfer ownership and deliver the property, and the buyer agrees to pay a certain price, under Article 1458 of the Civil Code. (Lawphil)

But unpaid RPT creates three practical consequences:

Issue	Effect
The tax follows the property	Real property tax becomes a lien on the land itself, not just a personal debt of the seller.
Registration may be blocked	The Register of Deeds generally requires real property tax clearance before issuing a new title.
The property may be levied or auctioned	If the tax remains delinquent, the local government may enforce collection through levy, auction, or court action.

So, while the sale document may be signed, notarized, and even binding between the parties, the buyer may not be able to complete the transfer of title unless the unpaid real property tax, interest, and related charges are resolved.

What Is Real Property Tax in the Philippines?

Real property tax is a local tax imposed on real property such as land, buildings, machinery, and improvements. Under Section 232 of the Local Government Code of 1991, a province, city, or municipality within Metro Manila may levy annual real property tax on real property not specifically exempted by law. (Supreme Court E-Library)

For ordinary property owners, RPT is usually paid at the City Treasurer’s Office or Municipal Treasurer’s Office where the property is located. The tax is based on the property’s assessed value, which comes from the local assessor’s records.

RPT commonly includes:

Basic real property tax
Special Education Fund tax, commonly an additional 1%
Idle land tax, if applicable
Special levies, in certain cases
Interest, penalties, and expenses, if the tax is delinquent

The tax is not paid to the BIR. It is paid to the local government unit, usually through the treasurer’s office.

Why Unpaid Real Property Tax Is a Big Deal in a Land Sale

Real Property Tax Becomes a Lien on the Property

Under Section 246 of the Local Government Code, real property tax accrues on January 1 of each year and from that date becomes a lien on the property, superior to other liens, mortgages, or encumbrances. (Supreme Court E-Library)

A lien means a legal claim or charge attached to the property. In simple terms, the local government has a legal hold over the land until the tax is paid.

Section 257 is even clearer: basic real property tax and other real property taxes constitute a lien on the property, superior to liens, charges, or encumbrances in favor of any person, and the lien may be extinguished only upon payment of the tax, related interest, and expenses. (Supreme Court E-Library)

This is why a buyer should never ignore unpaid RPT. Even if the seller promises to pay later, the unpaid tax can still affect the land.

The Register of Deeds Requires Real Property Tax Clearance

For titled land, the Land Registration Authority lists real property tax clearance showing up-to-date payment of taxes as a requirement for issuance of title transactions. The LRA also lists the original deed, latest tax declaration, owner’s duplicate certificate of title, BIR Certificate Authorizing Registration, and proof of transfer tax payment as key registration requirements. (Land Registration Authority)

This is the practical bottleneck in many sales.

A buyer may already have:

A notarized deed of absolute sale
Full payment receipts
BIR tax payment receipts
A BIR electronic Certificate Authorizing Registration, or eCAR
Transfer tax receipt

But without real property tax clearance, the Register of Deeds may not proceed with the transfer.

How Unpaid Real Property Tax Grows

Under Section 250 of the Local Government Code, real property tax may be paid in four equal installments: on or before March 31, June 30, September 30, and December 31. Payments are applied first to prior years’ delinquencies, interests, and penalties before being credited to the current period. (Supreme Court E-Library)

If the taxpayer fails to pay on time, Section 255 imposes interest of 2% per month on the unpaid amount or a fraction of a month, until fully paid, but the total interest cannot exceed 36 months. (Supreme Court E-Library)

This matters in negotiations. A seller who says, “Only three years unpaid,” may be surprised when the Treasurer’s Office computes:

Basic RPT
SEF
Idle land tax, if applicable
Interest
Prior-year balances
Possible publication or auction-related expenses

Always ask for an official Statement of Account or Tax Order of Payment from the Treasurer’s Office, not just an old tax receipt.

Can the Seller and Buyer Agree That the Buyer Will Pay the Back Taxes?

Yes. As between seller and buyer, they may agree that the buyer will pay the unpaid RPT. This is common when the buyer wants the land badly or when the unpaid tax is deducted from the purchase price.

But the agreement must be very clear.

A safe deed or side agreement usually states:

The exact amount of unpaid RPT, if already computed
Who will pay it
Whether it will be deducted from the purchase price
Whether payment must be made before notarization, before BIR filing, or before release of the final payment
What happens if the Treasurer’s Office later finds additional arrears
Whether the buyer may pay directly to the Treasurer and treat the payment as part of the purchase price

Without a clear written clause, disputes are common. The seller may later claim the buyer voluntarily assumed the taxes, while the buyer may insist the seller should deliver the property free from liens.

Under Article 1547 of the Civil Code, unless a contrary intention appears, the seller gives an implied warranty that he has the right to sell and that the buyer will enjoy legal and peaceful possession, and that the thing sold is free from hidden charges or encumbrances not declared or known to the buyer. (Lawphil)

Practical Ways to Sell Land With Unpaid Real Property Tax

Option 1: Seller Pays the RPT Before Signing the Deed

This is the cleanest option.

The seller goes to the City or Municipal Treasurer, pays all unpaid RPT, secures updated receipts, and obtains a real property tax clearance. The parties then sign and notarize the deed of sale.

This protects both sides because:

The buyer receives a cleaner transaction.
The seller avoids later accusations of hiding arrears.
BIR and Register of Deeds processing becomes smoother.
The sale price is easier to negotiate.

This is best when the arrears are manageable.

Option 2: Buyer Pays the RPT and Deducts It From the Price

This is also common.

Example:

Purchase price: ₱3,000,000
Unpaid RPT and interest: ₱180,000
Buyer pays ₱180,000 directly to the Treasurer’s Office
Buyer pays the seller the balance of ₱2,820,000

The deed or written agreement should say that the buyer’s RPT payment forms part of the purchase price. The buyer should keep:

Treasurer’s official receipt
Statement of Account
Tax clearance
Proof that the payment was for the exact property sold
Written acknowledgment from the seller

This approach is safer than giving the tax amount to the seller and hoping the seller pays.

Option 3: Use a Holdback From the Purchase Price

A holdback means the buyer withholds part of the purchase price until the seller clears the tax.

Example:

Buyer pays 80% upon signing.
Buyer holds 20% until the seller provides RPT clearance, BIR eCAR, and documents needed for title transfer.
If the seller fails to clear the RPT by a stated deadline, the buyer may pay the Treasurer directly and deduct it from the holdback.

This is useful when the exact tax amount is not yet known or when the LGU needs time to compute old arrears.

Option 4: Sell “Subject to” the Buyer Assuming the Tax

This is riskier but possible if both parties understand it.

A sale may state that the buyer purchases the property subject to unpaid real property taxes and assumes responsibility for payment. This may be acceptable to experienced buyers, developers, or relatives buying family land at a discount.

But for ordinary buyers, this is dangerous unless:

The exact arrears are known
There is no pending levy or auction
The title is checked for annotations
The discount reflects the tax risk
The buyer has enough cash to settle the RPT immediately

A buyer should not rely on the seller’s verbal statement that “the amilyar is small.” Old RPT can become expensive, especially if several years are unpaid.

Check the 2026 Real Property Tax Amnesty Before Closing

Republic Act No. 12001, the Real Property Valuation and Assessment Reform Act, created a temporary real property tax amnesty covering penalties, surcharges, and interest from unpaid real property taxes, including SEF, idle land tax, and other special levies incurred before the law’s effectivity. The law allows delinquent property owners to avail of the amnesty through one-time or installment payment within the two-year period, but excludes properties already disposed of at public auction, properties under compromise agreements, and properties subject to pending court cases for RPT delinquencies. (Supreme Court E-Library)

For sellers in 2026, this can be very important because the amnesty may substantially reduce the amount needed to clear old RPT. Several summaries of BLGF Memorandum Circular No. 003-2025 state that the amnesty covers unpaid RPT incurred before July 5, 2024 and is available until July 5, 2026. (InsightPlus)

Because implementation is handled locally, the seller should ask the Treasurer’s Office whether the property qualifies, what principal tax remains payable, and whether the LGU allows installment payment.

Step-by-Step Guide to Selling Land With Unpaid Real Property Tax

Step 1: Gather the Property Documents

Before negotiating seriously, prepare copies of:

Owner’s duplicate Transfer Certificate of Title or Original Certificate of Title
Latest tax declaration for land
Latest tax declaration for improvements, if any
Old RPT receipts
Valid government IDs of the seller and buyer
Marriage certificate, if the seller is married
Special Power of Attorney, if someone else will sign
Extrajudicial settlement or court documents, if the registered owner is deceased

If the seller is abroad, the SPA or deed signed overseas may need apostille or consular authentication, depending on where and how it is executed. The LRA notes that documents executed abroad require authentication by the nearest Philippine Consulate, while current BIR checklists also recognize consular certification or apostille for transfer documents and SPAs executed abroad. (Land Registration Authority)

Step 2: Request an Official RPT Computation

Go to the City or Municipal Treasurer’s Office where the property is located and request:

Statement of Account
Updated tax computation
Breakdown per year
Interest computation
Amnesty computation, if applicable
Certification if there is no delinquency
Information on any levy, auction notice, or pending enforcement

Bring the title number, tax declaration number, property identification number, and location details.

Step 3: Check the Title for Liens or Levy Annotations

A buyer should obtain a Certified True Copy of the title from the Register of Deeds or through authorized LRA channels. Check the memorandum of encumbrances for:

Notice of levy
Tax sale annotation
Mortgage
Adverse claim
Lis pendens
Attachment or execution sale
Restrictions under agrarian reform or subdivision laws

Under Section 258 of the Local Government Code, when real property is levied for unpaid RPT, notice of levy is served and the levy is annotated on the tax declaration and certificate of title. (Supreme Court E-Library)

If a levy is already annotated, the sale becomes much more sensitive. The buyer should not release full payment unless the tax delinquency and levy issue are resolved.

Step 4: Decide How the Tax Will Be Paid

The parties should agree in writing whether:

The seller pays the arrears before signing.
The buyer pays and deducts the amount from the price.
Part of the price is held back until clearance.
The buyer expressly assumes the unpaid RPT as part of the bargain.

For most ordinary sales, the safest arrangement is either seller payment before signing or buyer direct payment with deduction from the purchase price.

Step 5: Secure Real Property Tax Clearance

After payment, request the official RPT clearance from the Treasurer’s Office. Do not rely only on a receipt if the Register of Deeds requires a separate clearance.

The clearance should match:

Registered owner
Tax declaration number
Title number, if indicated
Property location
Land and improvement records
Year covered

If there is a building or other improvement with a separate tax declaration, make sure the improvement tax is also cleared.

Step 6: Execute and Notarize the Deed of Sale

The deed should identify the property clearly and state the parties’ tax agreement.

Important clauses may include:

Seller’s warranty that all RPT up to a specific date has been paid
Disclosure of unpaid RPT, if any
Agreement on who pays arrears
Authority of buyer to pay arrears and deduct from price
Holdback clause
Deadline for delivery of tax clearance
Consequences if additional arrears appear
Possession and turnover date

Under Article 1498 of the Civil Code, when a sale is made through a public instrument, execution of the instrument is generally equivalent to delivery of the thing sold, unless the deed shows a contrary intention. (Lawphil)

This is why the deed should not be carelessly signed before tax and possession issues are clear.

Step 7: Process BIR, Transfer Tax, and Register of Deeds Requirements

After notarization, the parties usually process:

Office	Main Purpose	Common Requirements
BIR RDO	Payment of national taxes and issuance of eCAR	Notarized deed, title, tax declarations, TINs, tax returns, proof of payment
City/Municipal Treasurer	Local transfer tax and RPT clearance	Deed, tax declaration, tax clearance, official receipts
Register of Deeds	Registration and issuance of new title	Original deed, owner’s duplicate title, BIR eCAR, transfer tax receipt, RPT clearance
Assessor’s Office	New tax declaration in buyer’s name	New title or registered deed, old tax declaration, transfer documents

BIR materials for one-time transactions list documents such as TINs of seller and buyer, notarized deed, certified true copies of tax declarations, title copies, SPA or secretary’s certificate where applicable, and proof of payment for eCAR processing. (Bir Cdn)

For BIR filing, capital gains tax on sale of real property classified as capital asset is generally filed using BIR Form 1706 within 30 days following the sale, while documentary stamp tax on real property transfers is generally filed using BIR Form 2000-OT within five days after the close of the month when the taxable document was made, signed, issued, accepted, or transferred. (Bir Cdn)

What If the Property Is Already Scheduled for Tax Auction?

This is urgent.

Under Section 254 of the Local Government Code, when RPT becomes delinquent, the treasurer must cause a notice of delinquency to be posted and published. The notice must state that unless the tax, surcharges, and penalties are paid before the expiration of the year for which the tax is due, the delinquent property may be sold at public auction, subject to the owner’s or interested person’s one-year right of redemption from the date of sale. (Supreme Court E-Library)

Under Section 260, within 30 days after service of the warrant of levy, the local treasurer proceeds to advertise the property for public sale or auction. The owner or person with legal interest may still stop the proceedings before the sale date by paying the delinquent tax, interest, and expenses of sale. (Supreme Court E-Library)

If the auction has already happened, Section 261 gives the owner or person with legal interest one year from the date of sale to redeem the property by paying the required amounts, including interest and sale expenses. (Supreme Court E-Library)

A buyer should be extremely careful with land that has already been levied, auctioned, or forfeited to the LGU. The transaction may involve redemption rights, auction purchaser rights, and strict deadlines.

Special Situations That Commonly Cause Problems

The Registered Owner Is Deceased

If the title is still in the name of a deceased parent or grandparent, unpaid RPT is only one issue. The heirs may also need:

Extrajudicial settlement of estate, if allowed
Publication once a week for three consecutive weeks
Estate tax settlement with BIR
eCAR for estate transfer
Settlement of RPT
Transfer or direct sale documents signed by all proper heirs

The LRA lists affidavit of publication, court approval for minors, and court documents for judicial settlement among additional title issuance requirements depending on the transaction. (Land Registration Authority)

A buyer should confirm that all heirs who must sign are actually signing.

The Seller Is Abroad

For overseas Filipinos, the usual issue is authority to sign. If the seller cannot come home, the seller may execute a Special Power of Attorney authorizing someone in the Philippines to sell the land, receive payment, pay taxes, and sign documents.

The SPA should be specific. A vague SPA “to transact with government offices” may not be accepted for sale of land. It should identify the property and expressly authorize sale, signing of the deed, payment of taxes, BIR processing, and registration.

The Buyer Is a Foreigner

A foreigner generally cannot buy private land in the Philippines by ordinary sale. Article XII, Section 7 of the 1987 Constitution provides that, except in cases of hereditary succession, private lands may be transferred only to individuals, corporations, or associations qualified to acquire or hold lands of the public domain. (Supreme Court E-Library)

This means unpaid RPT is not the main issue if the buyer is a foreign national buying land directly. The bigger issue is constitutional capacity to own the land. Common lawful alternatives may include purchase by a Filipino spouse in that spouse’s name, long-term lease structures, condominium ownership within allowed limits, or acquisition by a qualified Philippine corporation, depending on the facts.

The Tax Declaration Is Updated but the Title Is Not

A tax declaration is not the same as a land title. It is evidence used for tax assessment, but it does not by itself prove ownership the way a Torrens title does.

A buyer should compare:

Name on the title
Name on the tax declaration
Technical description
Lot number
Area
Location
Boundaries
Improvements declared

Discrepancies should be explained before payment.

There Are Improvements on the Land

Some properties have separate tax declarations for land and building. A seller may have paid the land tax but not the building tax, or vice versa.

Before closing, ask the Assessor’s Office whether there are separate declarations for:

Land
Residential building
Commercial building
Machinery
Other improvements

RPT clearance should cover all taxable components relevant to the sale.

Common Mistakes to Avoid

Signing the deed before knowing the exact RPT arrears
Paying the seller extra money “for amilyar” without proof of actual payment
Assuming the latest tax receipt means all prior years were paid
Ignoring separate tax declarations for improvements
Buying despite a levy annotation without understanding the auction timeline
Relying on tax declaration alone instead of checking the title
Forgetting BIR deadlines after notarization
Using a vague SPA for a seller abroad
Letting the buyer pay back taxes without a written deduction clause
Assuming the 2026 RPT amnesty applies even if the property was already auctioned or is in court

Frequently Asked Questions

Can I sell my land if I have unpaid amilyar?

Yes, you can agree to sell and sign a deed, but the unpaid amilyar must usually be settled before the buyer can complete title transfer. The unpaid tax is a lien on the property and the Register of Deeds commonly requires RPT clearance.

Who should pay unpaid real property tax, buyer or seller?

As a practical rule, the seller usually pays taxes up to the date of sale, unless the parties agree otherwise. The buyer may agree to pay the arrears if the amount is deducted from the purchase price and clearly stated in writing.

Can the buyer pay the unpaid RPT directly to the Treasurer?

Yes. This is often safer than giving the money to the seller. The deed or written agreement should state that the buyer’s payment to the Treasurer is part of the purchase price or is deductible from the amount payable to the seller.

Can the Register of Deeds transfer title without real property tax clearance?

In ordinary title issuance transactions, the LRA lists real property tax clearance showing up-to-date payment as a required document. Without it, registration may be delayed or refused. (Land Registration Authority)

What happens if real property tax is unpaid for many years?

The Treasurer’s Office may charge interest, issue notices of delinquency, levy the property, advertise it for public auction, and sell it to satisfy the tax delinquency. The owner or person with legal interest may have redemption rights if the property is sold at auction. (Supreme Court E-Library)

Is there a real property tax amnesty in the Philippines in 2026?

Yes, RA 12001 created a temporary amnesty for penalties, surcharges, and interest on certain unpaid RPT incurred before the law’s effectivity, subject to exclusions. Published summaries of BLGF MC No. 003-2025 state that the availment period runs until July 5, 2026. (Supreme Court E-Library)

Does unpaid RPT make the sale void?

Not automatically. The sale may still be valid between seller and buyer if the Civil Code requirements for a sale are present. But unpaid RPT can prevent smooth registration, expose the buyer to lien risks, and create breach of warranty issues if the seller failed to disclose it.

Can a buyer cancel the sale if the seller hid unpaid RPT?

Possibly, depending on the deed, negotiations, and facts. Under the Civil Code, the seller generally gives warranties against undisclosed charges or encumbrances unless the parties agreed otherwise. Remedies may include price reduction, damages, or rescission in proper cases. (Lawphil)

Can the LGU auction land even if it is being sold?

Yes. A private sale does not automatically stop the LGU’s collection remedies. If the RPT is delinquent and the legal requirements for levy and auction are followed, the LGU may proceed unless the delinquency, interest, and sale expenses are paid before the auction.

Should the deed of sale mention unpaid real property tax?

Yes. If there are unpaid taxes, the deed or a separate written agreement should clearly state the amount, who will pay, whether it is deducted from the price, and what happens if additional arrears are later discovered.
