How to Compute and Pay Capital Gains Tax
The capital gains tax on the sale of property in the Philippines is six percent, and almost everyone gets the calculation wrong the first time. It is not six percent of your profit. It is six percent of the property's value, whether you made money on the sale or lost it.
That single misunderstanding produces most of the confusion around CGT Philippines, along with a second one: the tax base is frequently higher than the price you actually agreed. This guide covers how capital gains tax is computed, which figure the BIR uses, who pays it, the deadline that carries penalties, how to file and pay, the exemption for selling a principal residence, and when the tax does not apply at all.

What Capital Gains Tax on Property Actually Is
Capital gains tax on real property is a six percent final tax imposed on the sale, exchange, or other disposition of real property located in the Philippines and classified as a capital asset.
It is a final tax, which means it is not credited against your income tax or adjusted at year end. Once paid, the matter is closed.
It applies to capital assets, not to ordinary assets. This distinction decides which tax regime applies, and it is the first thing to establish.
A capital asset is property not used in trade or business. A family home, an inherited lot, a vacant parcel held as an investment by an individual.
An ordinary asset is property held for sale to customers in the ordinary course of business, property used in trade or business, or property subject to depreciation. A developer's inventory and a company's office building are ordinary assets.
Where the property is an ordinary asset, capital gains tax does not apply. Creditable withholding tax applies instead, at rates that vary, and value-added tax may also apply. Establish the classification with a tax adviser before signing anything, because the computation and the documentary requirements differ substantially.
The Calculation Nobody Expects
Capital gains tax is computed on the highest of three figures.
- The gross selling price, being what the buyer actually pays.
- The BIR zonal value, being the valuation the Bureau of Internal Revenue maintains for the area.
- The fair market value as shown in the tax declaration, being the Assessor's valuation.
Take a residential lot sold for ₱4,000,000. The BIR zonal value for the area is ₱5,000,000. The fair market value per the tax declaration is ₱3,500,000.
The tax base is ₱5,000,000, being the highest of the three. Capital gains tax at six percent is ₱300,000, not the ₱240,000 the selling price alone would suggest.
Your acquisition cost is irrelevant. Whether you bought the property for ₱1,000,000 or ₱4,500,000 makes no difference. You pay the same six percent even if you sold at a loss, which surprises sellers offloading a property in a soft market.
Check the zonal value before you agree a price. The BIR publishes zonal valuation schedules, and a seller who discovers after signing that the zonal value exceeds the agreed price has a tax bill larger than they budgeted for.
Who Pays It
By law, the seller is liable for capital gains tax. It is a tax on the disposition, and the person disposing bears it.
In practice it is negotiated, and both allocations are common. Some transactions have the buyer absorb it as part of the price arrangement, particularly where the buyer wants the transfer completed quickly and does not trust the seller to file.
Whatever you agree, put it in the deed. An unstated assumption about who pays which tax is the most common source of friction at closing.
The customary split in Philippine practice is capital gains tax to the seller, documentary stamp tax and transfer tax to the buyer, with registration fees to the buyer. This is convention rather than law, and it is negotiable.
The Deadline That Carries Penalties
Capital gains tax is due within thirty days of notarization of the deed of sale.
That clock runs from notarization, not from when you are ready to file. This is the single most expensive mistake in Philippine property transactions.
Do not notarize the deed until the parties are prepared to proceed. A deed notarized weeks before anyone assembles the documents has started a clock that will not stop, and late filing attracts a surcharge, interest, and a compromise penalty.
Documentary stamp tax runs on a different clock, due by the fifth day of the month following notarization. The two deadlines are not the same and both must be met.
How to File and Pay
File BIR Form 1706, the Capital Gains Tax Return for onerous transfer of real property classified as a capital asset.
Go to the Revenue District Office with jurisdiction over the property location, not over your residence.
Prepare the supporting documents, which typically include the notarized deed of absolute sale, the certified true copy of the title, certified true copies of the latest tax declarations for land and improvements, valid identification and TINs for both parties, and the real property tax clearance.
The deed must show the TINs of both buyer and seller. A deed without them will be returned.
Pay at an Authorized Agent Bank, then submit the deposit slips with your document set to the RDO.
The RDO processes the filing and issues the electronic Certificate Authorizing Registration, the eCAR. Without it, the Registry of Deeds will not register the transfer, so the eCAR is the actual output of this step.
Where the filing is done through a representative, a Special Power of Attorney is required, notarized locally or apostilled if executed abroad.
The Principal Residence Exemption
There is a genuine exemption available to individuals selling their family home, and it is underused because the conditions are specific.
The sale of a principal residence may be exempt from capital gains tax where the proceeds are fully used to acquire or construct a new principal residence, subject to strict conditions.
The conditions generally require the following.
- The property sold must be the seller's actual principal residence.
- The full proceeds must be used to acquire or construct a new principal residence within the prescribed period, commonly eighteen months from the date of sale.
- The Commissioner of Internal Revenue must be notified of the intention to avail of the exemption, within the prescribed period from the date of sale.
- The exemption may generally be availed of only once every ten years.
- The historical cost or adjusted basis of the property sold carries over to the new residence.
Where only part of the proceeds is used, the exemption is proportional and tax is due on the unutilized portion.
The notification requirement is where this exemption is most often lost. A seller who used the proceeds correctly but never notified the BIR within the period has a difficult conversation ahead. Raise this with a tax adviser before the sale, not after.
When Capital Gains Tax Does Not Apply
Ordinary assets. Creditable withholding tax applies instead, and VAT may apply. Developers, corporations holding property for business use, and anyone dealing in real estate as a trade fall here.
Transfers that are not sales. Donations attract donor's tax. Transfers on death attract estate tax. Neither is a capital gains tax event.
Certain transfers to the government and transactions expressly exempted under the tax code.
Shares of stock are treated under separate provisions, though a corporation whose assets are principally real property carries its own considerations.
Expropriation and sales to the government may be subject to an election between capital gains tax treatment and ordinary income treatment, which is worth advice.
Where This Sits in the Transfer Process
Capital gains tax is step one of five, and the sequence cannot be rearranged.
Notarize the deed. Pay CGT and DST at the BIR. Secure the eCAR. Pay transfer tax at the Treasurer. Register at the Registry of Deeds. Update the tax declaration at the Assessor.
Each office requires the output of the one before it. You cannot pay transfer tax without BIR-stamped documents, and you cannot register without the eCAR.
Total transaction cost across the whole sequence runs roughly eight to twelve percent of property value, of which capital gains tax at six percent is the largest single item.
Documentary stamp tax adds 1.5 percent, transfer tax 0.5 to 0.75 percent, and registration fees roughly a quarter of one percent on the LRA graduated scale, plus notarial and incidental costs.
Practical Points That Save Money
Check the zonal value before agreeing the price. If zonal value exceeds your selling price, you are paying tax on a figure higher than you received, and that should be factored into the negotiation rather than discovered afterwards.
Establish capital asset versus ordinary asset at the outset. Getting this wrong means filing the wrong return and paying the wrong tax.
Do not notarize early. Once notarized, the thirty-day clock runs regardless of whether your documents are ready.
Settle amilyar before the sale. You cannot obtain a real property tax clearance while arrears exist, and without the clearance the transfer stops.

Read the annotations on the certified true copy of the title. An uncancelled mortgage from years ago must be released before a clean transfer, and it takes time to locate a lender who has since merged or closed.
Keep every receipt and the brown copy of the eCAR, alongside your new title and tax declaration. They form the document set for the property for the rest of your ownership.
Engage a tax adviser before the deed is drafted, not after it is signed. The structural questions of asset classification, VAT treatment, and exemption eligibility are all decided at that point, and unwinding an executed document costs considerably more than reviewing a draft.
Capital gains tax is the largest single cost in a Philippine property sale, and the figure it is computed on is frequently higher than the price agreed.
