What Is BIR Zonal Value? How It Sets the Minimum Tax Base for Capital Gains Tax, DST, and Estate Tax
BIR zonal value is the per-square-meter valuation the Bureau of Internal Revenue assigns to real property within a defined zone, used as a floor for computing capital gains tax, documentary stamp tax, estate tax, and donor’s tax on property transactions. Whenever a property’s actual selling price is lower than its BIR zonal value, the BIR computes tax on the zonal value instead — a seller and buyer cannot reduce their tax base simply by agreeing to a lower price on paper.

Zonal value is the BIR’s own valuation of real property, set independently of both the parties’ agreed selling price and the local government’s assessed value, and it is published per Revenue District Office (RDO) by street, subdivision, or barangay. The BIR periodically reviews and revises zonal valuation schedules; a given area can carry the same published rate for years even while actual market prices move, which is why the “higher of” rule below matters in practice.
Why does the BIR use the higher of three values? #
Section 6(E) of the National Internal Revenue Code (NIRC) requires the BIR to compute capital gains tax and documentary stamp tax (DST) on whichever is highest among the gross selling price, the BIR zonal value, and the local assessor’s fair market value — not simply on the price stated in the deed of sale. This “higher of” rule exists specifically to stop parties from understating a deed’s consideration to shrink the tax base. In practice, for most residential and commercial lots, BIR zonal value ends up being the controlling figure because it is set closer to prevailing market conditions than an assessor’s schedule, which local governments revise less frequently.
| Value | Set by | Purpose |
|---|---|---|
| Selling price | Buyer and seller | Contract price stated in the deed of sale |
| BIR zonal value | BIR, per RDO | Minimum tax valuation for internal revenue taxes |
| Assessor’s fair market value | City/municipal assessor | Basis for local real property tax (amilyar) |
Which taxes actually use zonal value? #
Zonal value feeds directly into the computation of at least four separate BIR taxes on real property, each using the same “higher of” comparison but applying a different rate.
- Capital gains tax — 6% of the higher of selling price, zonal value, or assessed fair market value, on the sale of real property classified as a capital asset. See BIR Form 1706.
- Documentary stamp tax — 1.5% of the same base, under NIRC Section 196, reported on BIR Form 2000-OT.
- Estate tax — real property included in a decedent’s gross estate is valued at the higher of its zonal value or the assessor’s fair market value at the time of death.
- Donor’s tax — real property transferred by gift uses the same higher-of-zonal-or-assessed-value rule to compute the value of the donation.
Worked example: when zonal value overrides the contract price #
A property sold below its zonal value is still taxed on the zonal value, not the lower contract price the parties agreed to.
A seller agrees to sell a residential lot in Quezon City for ₱3,000,000. The BIR zonal value for that street is ₱4,500 per square meter, and the lot measures 800 square meters — putting the zonal value at ₱3,600,000, higher than the agreed selling price. The local assessor’s fair market value for the same lot is ₱3,200,000.
| Value | Amount |
|---|---|
| Selling price (as stated in the deed) | ₱3,000,000 |
| BIR zonal value (₱4,500/sqm × 800 sqm) | ₱3,600,000 |
| Assessor’s fair market value | ₱3,200,000 |
| Tax base used (highest of the three) | ₱3,600,000 |
Capital gains tax is computed as 6% × ₱3,600,000 = ₱216,000, and DST as 1.5% × ₱3,600,000 = ₱54,000 — both based on the zonal value, not the ₱3,000,000 actually paid. A seller who filed based on the ₱3,000,000 contract price would face a deficiency assessment for the difference plus surcharge and interest under BIR late filing and deficiency rules.
Frequently asked questions #
What is BIR zonal value? #
BIR zonal value is the per-square-meter valuation the Bureau of Internal Revenue assigns to real property within a defined zone — a street, subdivision, barangay, or municipality — for computing internal revenue taxes on property transactions. It is set and periodically revised by the BIR’s Revenue District Offices, independently of a local government’s assessed value or an owner’s asking price.
Is zonal value the same as the selling price? #
No. The selling price is what a buyer and seller actually agree to pay. Zonal value is the BIR’s own valuation for tax purposes. Under Section 6(E) of the NIRC, the BIR computes capital gains tax and documentary stamp tax on whichever is higher: the selling price, the BIR zonal value, or the local assessor’s fair market value — a low selling price does not reduce the tax base below zonal value.
How do I find the zonal value of a specific property? #
The BIR publishes zonal valuation schedules by Revenue District Office, listing rates per square meter for specific streets, subdivisions, and barangays. A taxpayer can request a certified zonal value from the RDO that has jurisdiction over the property’s location, or check the BIR’s published zonal value tables for that RDO.
What taxes use BIR zonal value as part of the computation? #
Zonal value is used to compute capital gains tax on the sale of real property classified as a capital asset (6% of the higher of selling price, zonal value, or assessed fair market value), documentary stamp tax on the same transaction (1.5% on the same base), and the value of real property included in an estate for estate tax or a gift for donor’s tax purposes.
Does zonal value ever go down or stay outdated for years? #
Zonal values are revised periodically by the BIR, not on a fixed annual schedule, and a given zone’s value can stay unchanged for several years even as market prices rise. When a property’s actual market value has clearly outpaced its zonal value, the BIR still uses whichever of selling price, zonal value, or assessed fair market value is highest — so an outdated (lower) zonal value does not reduce the tax base if the actual selling price is already higher.
Summary #
BIR zonal value is a per-square-meter valuation the BIR sets by area and uses, together with the selling price and the assessor’s fair market value, to determine the minimum tax base for capital gains tax, DST, estate tax, and donor’s tax under the “higher of” rule in NIRC Section 6(E). Before finalizing a deed of sale, check the published zonal value for the property’s RDO — a contract price below zonal value does not lower the tax due. See Capital Gains Tax vs Real Property Tax for how the resulting tax base flows into actual filing.
