Quick answer
For a Philippine sale of real property classified as a capital asset, calculate both taxes using the highest of:
- The selling price or consideration stated in the deed;
- The BIR zonal value; or
- The fair market value shown in the provincial or city assessor’s schedule of values or tax declaration.
Then apply:
- Capital gains tax (CGT):
6% × tax base - Documentary stamp tax (DST):
₱15 × ceiling(tax base ÷ ₱1,000)
DST is therefore approximately 1.5%, but every fraction of ₱1,000 is rounded up to the next ₱1,000.
The first question is whether the property is a capital asset or an ordinary asset. If it is an ordinary asset—such as property held for sale by a developer or used in the seller’s business—the 6% CGT generally does not apply. Ordinary income tax, expanded withholding tax, VAT or percentage tax may apply instead. DST usually remains due.
The basic calculation
Let:
SP= selling price or consideration in the deedZV= applicable BIR zonal valueAFMV= fair market value shown in the assessor’s schedule or tax declaration
The tax base is:
Tax base = highest of SP, ZV, and AFMV
The taxes are:
CGT = tax base × 6%
DST = ₱15 × ceiling(tax base ÷ ₱1,000)
Do not use the property’s acquisition cost, outstanding mortgage, net proceeds, brokerage commission, renovation expenses or the seller’s actual profit to reduce this tax base. The 6% tax is imposed on a gain presumed to have been realized. It can therefore be due even if the seller actually lost money. The Supreme Court has recognized this treatment in CIR v. Aquafresh Seafoods, Inc., G.R. No. 160756.
Also distinguish the assessor’s fair market value from the lower assessed value used to compute real property tax. For CGT and DST, the relevant figure is the fair market value before application of the assessment level.
Worked example
Assume a house-and-lot sale has these values:
- Price in the deed: ₱5,000,000
- BIR zonal value: ₱5,600,000
- Assessor’s fair market value: ₱4,700,000
The highest amount is ₱5,600,000, so this is the tax base.
Capital gains tax
₱5,600,000 × 6% = ₱336,000
Documentary stamp tax
₱5,600,000 ÷ ₱1,000 = 5,600 units
5,600 × ₱15 = ₱84,000
Total CGT and DST
₱336,000 + ₱84,000 = ₱420,000
This total does not include local transfer tax, registration fees, notarial charges, unpaid real property taxes, association clearances or other transfer expenses.
When the tax base is not an exact multiple of ₱1,000
If the tax base is ₱5,600,500:
₱5,600,500 ÷ ₱1,000 = 5,600.5
Round that up to 5,601 units:
5,601 × ₱15 = ₱84,015 DST
Simply multiplying by 1.5% would produce ₱84,007.50 and understate the DST.
Confirm whether the property is a capital asset
The classification depends on the property’s character in the hands of the seller, not the buyer’s intended use.
| Situation | Usual classification and tax treatment |
|---|---|
| Personal home, inherited land or investment property never used in business by an individual not engaged in real estate | Usually a capital asset; 6% CGT generally applies |
| Inventory of a real estate dealer or developer | Ordinary asset; no 6% CGT |
| Property held primarily for sale to customers in the ordinary course of business | Ordinary asset |
| Building, rental property or land used in the seller’s trade or business | Generally an ordinary asset |
| Business property that became idle | It does not automatically become a capital asset |
| Land or building sold by a domestic corporation and classified as a capital asset | Generally subject to 6% CGT |
| Property sold by a resident or nonresident foreign corporation | Different income-tax rules may apply; do not assume the 6% CGT applies |
BIR Revenue Regulations No. 7-2003 contains the detailed classification rules. Among other qualifications, property used in a non-real-estate business may be converted to a capital asset upon adequate proof that it was no longer used in business for more than two years before the transaction. Property originally held as inventory by a real estate business generally remains an ordinary asset even after becoming idle.
Classification should be resolved before the deed is signed. An incorrect classification can change not only the income tax but also the withholding, invoicing and VAT or percentage-tax consequences.
How to determine the three values
Selling price
Use the full consideration contracted to be paid, as reflected in the deed and related agreements. Side payments, assumed obligations and inconsistent contract documents can lead to reassessment or allegations that the consideration was understated.
BIR zonal value
Locate the property in the applicable BIR schedule based on:
- Revenue District Office;
- City or municipality;
- Barangay, street or condominium project;
- Property classification, such as residential, commercial or industrial; and
- Effective date of the zonal-value schedule.
For land, the value commonly begins with the area multiplied by the applicable rate per square metre. Condominium units, parking slots and improvements can have separate classifications or valuation rules. Use the schedule effective on the transaction date, not one downloaded for an earlier negotiation.
Current schedules are available through the BIR’s official zonal-values page.
Assessor’s fair market value
Obtain certified tax declarations for both land and improvements, where applicable. Use the fair market value appearing in the assessor’s records—not merely the amount of annual real property tax or the assessed value.
If the property has no improvement, the BIR may require a certificate of no improvement from the assessor. Undeclared or newly constructed improvements can delay the computation and issuance of the electronic Certificate Authorizing Registration.
Who pays the taxes?
As an economic matter, the seller ordinarily bears the CGT, while sale contracts often assign DST to the buyer. The parties may negotiate a different allocation.
For BIR compliance, however:
- BIR Form 1706 identifies the buyer and seller as joint filers and instructs the buyer or transferee to withhold and deduct the 6% CGT from the agreed consideration.
- BIR Form 2000-OT is filed by the person making, signing, issuing, accepting or transferring the taxable document.
- If one party is exempt from DST, the non-exempt party may be directly liable.
A contractual clause shifting a tax cost between buyer and seller does not eliminate the tax or prevent the BIR from enforcing the governing tax rules.
Filing forms and deadlines
| Tax | Form | General deadline |
|---|---|---|
| Capital gains tax on capital-asset real property | BIR Form 1706 | Within 30 days following the sale, exchange or disposition |
| Documentary stamp tax on the deed | BIR Form 2000-OT | Within five days after the close of the month in which the taxable document was made, signed, issued, accepted or transferred |
These are separate deadlines. Do not assume that paying CGT also pays DST, or that either deadline waits for the Register of Deeds to transfer the title.
BIR Form 1706 and its instructions state the 30-day rule. BIR Form 2000-OT and its instructions state the five-days-after-month-end rule.
Electronic filing and available BIR payment channels should be used in accordance with current BIR instructions. Payments may generally be made through authorized agent banks, Revenue Collection Officers or available electronic payment facilities. The Ease of Paying Taxes implementing rules changed older venue restrictions, but the ONETT review and eCAR application are still routed to the appropriate BIR office handling the property transaction.
Practical ONETT and eCAR process
Resolve the seller and asset classification. Confirm whether the seller is an individual, estate, trust or corporation and whether the property is capital or ordinary.
Gather the valuation records. Obtain the current zonal-value schedule and certified assessor’s tax declarations for the land and all improvements.
Prepare a consistent deed. Names, TINs, civil status, title numbers, property descriptions, consideration and dates should match the title, tax declarations and supporting contracts.
Request the ONETT computation. The transaction may be submitted through the BIR eONETT system or processed under the procedure of the concerned RDO. The BIR reviews the documents and issues an approved ONETT Computation Sheet.
File the correct returns and pay on time. File Form 1706 and Form 2000-OT and retain the electronic confirmation, validated bank documents or Revenue Official Receipt. Do not allow an unfinished computation request to push the transaction beyond a statutory deadline; coordinate promptly with the concerned RDO if the deadline is close.
Submit proof for the eCAR. The BIR requires the filed returns, proof of payment or exemption, approved computation sheet, transfer document and applicable authority documents.
Obtain the eCAR. The Register of Deeds ordinarily requires the eCAR before registering the transfer. BIR materials also prescribe a certification fee and loose documentary stamp for the eCAR, which are separate from the DST on the deed.
The current documentary checklists are in the annexes to BIR Revenue Memorandum Order No. 17-2026.
Documents and evidence to preserve
Keep both paper and clear digital copies of:
- Notarized deed of absolute sale or other transfer document;
- Contract to sell, payment schedule and receipts, if payment is deferred or by installment;
- Certified copy of the OCT, TCT or CCT;
- Certified tax declarations for land and improvements;
- Certificate of no improvement, when applicable;
- BIR zonal-value schedule effective on the transaction date;
- TIN information for every seller and buyer;
- Government-issued IDs and civil-status documents;
- Special power of attorney, secretary’s certificate or board resolution, when applicable;
- Apostille or Philippine consular certification for documents executed abroad;
- Approved ONETT Computation Sheet;
- Filed Forms 1706 and 2000-OT;
- Bank validation, Revenue Official Receipt or electronic payment confirmation;
- eCAR and claim slip;
- Evidence of how the sale proceeds were received and applied; and
- Written allocation of taxes and closing expenses between the parties.
Preserve earlier drafts and related agreements if they explain the true date, price or installment terms. Do not create a second deed with a different price merely to satisfy a lender, broker or informal arrangement.
Important exceptions and special situations
Sale of a principal residence
A natural person may qualify for CGT exemption when the proceeds from the sale of a genuine principal residence are fully used to acquire or construct a new principal residence within 18 calendar months from the sale.
Key conditions include:
- The seller must notify the BIR of the intention to claim the exemption within 30 days from the sale through the prescribed return and sworn documentation;
- The exemption may generally be used only once every 10 years;
- The historical cost or adjusted basis of the old residence carries over to the new one;
- The prescribed escrow arrangement for the otherwise-due CGT must be followed; and
- Proof of purchase or construction and a sworn statement of utilization must be submitted.
If only part of the proceeds is used, CGT applies proportionately to the unutilized portion. A working formula is:
CGT = 6% × higher tax base × (unutilized proceeds ÷ gross selling price)
The BIR should validate the calculation and documentation. This exemption concerns CGT; DST on the deed generally remains due unless a separate exemption applies.
Installment and deferred-payment sales
A sale may qualify for installment treatment when the applicable legal conditions are met, generally including initial payments in the year of sale not exceeding 25% of the selling price. BIR Form 1706 provides for filing and payment within 30 days after the first downpayment and each subsequent installment where installment payment of CGT is legally allowed.
Deferred-payment and installment transactions are not interchangeable. The timing of the contract to sell, deed of absolute sale, collections and transfer of possession matters. For DST, BIR instructions state that in an installment or deferred-payment arrangement, DST accrues upon execution of the deed of absolute sale, while its base is determined using the higher selling price or fair market value at the time of the contract to sell.
Sale to the government
For an individual’s disposition of a capital asset to the government, a political subdivision, government agency or government-owned or controlled corporation, the seller may have a statutory option between the 6% final CGT and taxation under the applicable regular income-tax rules.
For DST, when one contracting party is the government, the tax is based on actual consideration under the statutory rule. Obtain transaction-specific advice before exercising the income-tax option.
Mortgage foreclosure
BIR Form 2000-OT states that DST in a mortgage foreclosure sale is based on actual consideration. Foreclosure does not, by itself, change whether the property was a capital or ordinary asset in the mortgagor’s hands.
Tax-free exchanges and transfers under special laws
Corporate reorganizations, mergers, qualifying tax-free exchanges, agrarian-reform transfers, socialized-housing transactions and transfers involving entities with statutory exemptions can follow different rules. An income-tax exemption does not automatically create a DST exemption. Obtain the required BIR ruling or certificate of tax exemption where the applicable rule calls for one.
Common mistakes
- Automatically multiplying the deed price by 6% and 1.5% without checking the two official fair market values;
- Using assessed value instead of the assessor’s fair market value;
- Applying CGT to property that is actually an ordinary asset;
- Assuming a capital asset because the property is currently vacant;
- Using an outdated zonal-value schedule or the wrong street, barangay or property classification;
- Ignoring a separately titled parking slot or undeclared improvement;
- Deducting acquisition cost, commissions, mortgage balance or renovation expenses from the CGT base;
- Treating DST as exactly 1.5% without rounding every fractional ₱1,000 upward;
- Waiting for full payment or title registration before checking the tax deadlines;
- Claiming the principal-residence exemption without timely notice, escrow and proof of reinvestment;
- Assuming a low price between relatives prevents tax because no profit was earned;
- Losing the validated returns or electronic payment references needed for the eCAR; and
- Signing inconsistent deeds, contracts to sell or receipts showing different prices or dates.
Late filing or payment can produce surcharge, interest and compromise penalties. The standard civil surcharge for covered failures is generally 25%, while qualified micro and small taxpayers receive reduced penalties under the Ease of Paying Taxes Act. Fraudulent returns and willful nonfiling can carry more serious consequences. Ask the BIR to compute late-payment additions rather than guessing.
When professional help is urgent
Consult a Philippine tax lawyer, CPA or experienced ONETT practitioner before signing—or immediately after discovering a problem—when:
- The property was rented, depreciated or used in any business;
- The seller is a developer, dealer, corporation, estate, trust or foreign person;
- There are several sellers, deceased co-owners or unresolved marital-property issues;
- The transaction involves a contract to sell, installment payments, assignment of rights or foreclosure;
- The deed price is materially below market value;
- The principal-residence exemption is being claimed;
- The seller previously claimed that exemption within the last 10 years;
- The property has multiple titles, improvements or conflicting classifications;
- The deed was signed earlier but no tax return was filed;
- Documents contain different transaction dates or prices;
- A tax-free exchange or special-law exemption is claimed; or
- The BIR valuation or proposed classification appears incorrect.
Frequently asked questions
Is CGT based on the seller’s actual profit?
No. For a qualifying capital-asset sale, it is 6% of the higher selling price or official fair market value. Acquisition cost and selling expenses do not reduce that base.
Is DST always 1.5%?
It is ₱15 for every ₱1,000 or fractional part. It equals 1.5% only when the base is an exact multiple of ₱1,000; otherwise, the fraction is rounded upward.
What if the zonal value is higher than the selling price?
Use the zonal value if it is also higher than the assessor’s fair market value. The parties’ lower contract price does not control the tax base.
What if the assessor’s value is highest?
Use the assessor’s fair market value as the base for both CGT and DST, subject to any specific statutory exception such as the DST rule for government or foreclosure transactions.
Does the buyer’s intended use determine whether CGT applies?
No. Classification is determined in relation to the seller at the time of sale.
Is a residential property automatically a capital asset?
No. A residential unit can be an ordinary asset if it is inventory, held for sale in a real estate business, rented out as part of the seller’s business or otherwise used in trade or business.
Does the principal-residence exemption also remove DST?
Generally, no. It is a CGT exemption. DST remains payable unless an independent exemption applies.
Can the parties agree that the buyer will pay CGT?
They can allocate the economic cost in their contract, but that agreement does not change the tax’s legal character or the BIR filing and withholding requirements.
Are transfer tax and registration fees included?
No. Local transfer tax, Registry of Deeds fees, notarial costs, real property tax clearances and other closing expenses are separate.
