BIR Zonal Value of Property in the Philippines: How to Check and Use It

BIR zonal value is the government-set peso-per-square-meter benchmark that the Bureau of Internal Revenue uses to compute national taxes on a property sale, donation, or inheritance — capital gains tax, documentary stamp tax, donor’s tax, and estate tax are all based on the higher of the zonal value, the local assessor’s fair market value, or the actual selling price stated in the deed. You check it by finding the Revenue District Office (RDO) that covers the property’s location on the BIR website and matching the exact barangay, street, or subdivision in that RDO’s published schedule (BIR Zonal Values). A 2024 law is gradually replacing this system with a unified valuation standard, so the figure you find today may not be the final word — verify with your RDO before relying on it for a transaction.

Decision Snapshot

• What it is: A government-prescribed value per square meter, set by the BIR for each barangay/zone, used as a tax base — not a market appraisal and not what a buyer would actually pay.
• Where to check it: bir.gov.ph/zonal-values, organized by Revenue Region and Revenue District Office (RDO).
• Which RDO matters: The RDO with jurisdiction over the property’s location — not the owner’s or buyer’s residence.
• Main taxes that use it: Capital gains tax (6% on capital assets), documentary stamp tax (1.5%), donor’s tax (6% on the excess over the exempt amount), and estate tax (6% of net estate).
• Important 2026 caveat: Republic Act No. 12001 (2024) is replacing BIR zonal values with a unified Schedule of Market Values (SMV) maintained by local assessors, with a transition period running into 2026. Existing zonal values remain in force until superseded in a given locality.
• Next step: Confirm the exact figure with your property’s RDO or a BIR-accredited appraiser before using it in a tax computation, since schedules are updated periodically and not every street is listed individually.

What Is BIR Zonal Value?

Zonal value is a valuation the Bureau of Internal Revenue assigns to real property within a defined zone — typically a barangay, subdivision, or a stretch of a named street — expressed in pesos per square meter. It is set by classification (residential, commercial, industrial, agricultural) and by location factors such as road access and distance from a main thoroughfare (Respicio & Co., How to Check the BIR Zonal Value of Property in the Philippines).

It is not an appraisal of what a specific unit or lot is worth. Two lots on the same street with the same zonal value can have very different market prices depending on condition, view, or improvements. Zonal value exists for one purpose: to give the BIR a minimum, geography-based benchmark so that national taxes on a property transfer cannot be understated by declaring an unrealistically low selling price in the deed.

What BIR Zonal Value Is Used For

For a sale of real property classified as a capital asset (most owner-occupied homes and condo units held for personal use, as opposed to inventory held by a real estate dealer), the BIR computes the transaction’s tax base as the higher of: the gross selling price stated in the deed, the BIR zonal value at the time of sale, or the local assessor’s fair market value on the tax declaration (Respicio & Co., Capital Gains Tax in the Philippines: Rates and Calculation). That base then drives several separate taxes:

These rates reflect the National Internal Revenue Code as amended by the TRAIN Law and are cross-checked against multiple current summaries (Respicio & Co., Capital Gains Tax; REN.PH, Documentary Stamp Tax Philippines). Rates and exemption thresholds can change by legislation, so confirm the current figures with the BIR or a tax professional before filing, especially for donor’s and estate tax computations, which involve additional deductions and exemptions this guide does not cover in full.

How to Check the BIR Zonal Value of a Property

The BIR publishes zonal values by Revenue Region and Revenue District Office rather than as a single searchable database, so the process is manual. Follow these steps (adapted from Respicio & Co.’s verification walkthrough and the official BIR Zonal Values page):

1. Go to the official BIR Zonal Values page at bir.gov.ph/zonal-values. Do not rely on third-party zonal value lookup sites for a live transaction — use them only as a rough starting point, then confirm on the official page or with the RDO.
2. Identify the correct Revenue District Office (RDO). This is the RDO with jurisdiction over where the property is physically located, not where the owner or buyer resides or is registered. The property’s city or municipality determines the RDO.
3. Open the current zonal value schedule (PDF) for that RDO. These are typically organized as revenue district schedules covering all barangays within that district.
4. Search for the exact city or municipality using the spelling that appears on the property’s tax declaration, since schedules can use official rather than colloquial place names.
5. Locate the correct barangay section, then find the specific street, subdivision, or condominium project listed under it.
6. Confirm the property classification shown — residential, commercial, industrial, or agricultural — matches the actual use, since the same street can carry different zonal values by classification.
7. Note that the figure is per square meter of land area (or, for condominium units, per square meter of unit floor area under a separate condominium schedule), then multiply by the property’s documented area to get the zonal value of the whole property.
8. If the street or subdivision is not individually listed, the RDO may apply a default classification for that barangay, or you may need to request a certification directly from the RDO.

For condominium units, zonal values are usually published in a separate schedule per project or per general commercial/residential-condominium classification within the RDO, rather than folded into the land schedule — check both if you don’t find the property under the general listing.

Zonal Value vs. Fair Market Value vs. Assessed Value

These three terms are often used loosely and confused with each other. Here is the practical distinction, based on how the BIR and local assessors actually use each figure:

The BIR uses the higher of zonal value or the assessor’s fair market value (not the lower assessed value) when comparing against the declared selling price (Respicio & Co.). A tax declaration’s assessed value is almost always the smallest of the three figures, which is why relying on it alone tends to understate the taxes actually due on a sale, donation, or inheritance.

Why the Zonal Value System Is Changing in 2026

Republic Act No. 12001, the Real Property Valuation and Assessment Reform Act (RPVARA), was signed into law on June 13, 2024. It creates a single, LGU-by-LGU Schedule of Market Values (SMV) maintained by local assessors under the supervision of the Bureau of Local Government Finance (BLGF), intended to eventually replace both the separate BIR zonal valuation system and each city or municipality’s own fair market value schedule with one unified figure (Republic Act No. 12001, Supreme Court E-Library; full text via LawPhil).

Under the law’s transitory provisions, existing BIR zonal values remain valid and continue to apply until they are formally superseded by an approved SMV in that locality — the law gives local government units up to two years from its effectivity to adopt updated SMVs (RA 12001, Sections 29 and 31). In the interim, where an updated SMV is not yet available for a given area, the BIR is directed to use the higher of the existing zonal value, the existing SMV, or the actual transaction price declared. Because SMV adoption is happening on a per-LGU basis and rollout pace varies by locality, this article cannot confirm which cities or municipalities have already transitioned to a new SMV as of this writing — treat any zonal value you find as provisional and confirm the currently applicable valuation directly with the property’s RDO or the local assessor’s office before finalizing a tax computation.

Worked Example: How Zonal Value Affects the Tax Bill

The figures below are a hypothetical illustration only — not a real property, not a real zonal value, and not tax advice. They exist to show the mechanics of the calculation, not to predict what any specific transaction will cost.

• Inputs: A 60 sqm condo unit sold with a deed of sale price of ₱3,000,000. For illustration, assume a hypothetical zonal value of ₱55,000/sqm for that unit’s classification (₱3,300,000 total) and an assessor’s fair market value of ₱3,100,000.
• Step 1 — determine the tax base: Compare all three figures (₱3,000,000 selling price; ₱3,300,000 zonal value; ₱3,100,000 assessor’s FMV) and use the highest: ₱3,300,000.
• Step 2 — capital gains tax: 6% × ₱3,300,000 = ₱198,000.
• Step 3 — documentary stamp tax: 1.5% × ₱3,300,000 = ₱49,500.
• Result: Because the hypothetical zonal value was higher than the actual selling price, both taxes were computed on ₱3,300,000 rather than the ₱3,000,000 the parties agreed to — a ₱54,000 higher combined CGT and DST bill than if the selling price alone had been used.

This is the practical reason zonal value matters even to buyers and sellers who never interact with the BIR directly: it can raise the tax bill above what the contract price alone would suggest, and closing costs are frequently negotiated around who absorbs that difference.

What to Verify Before You Rely on a Zonal Value

• Confirm the RDO is correct for the property’s exact address, not an adjacent district.
• Confirm you have the current schedule. RDOs periodically issue updated Revenue District schedules; an outdated PDF found through a search engine may not reflect the latest figures.
• Check whether RA 12001’s Schedule of Market Values has already taken effect for that specific LGU, since this can change which figure legally applies.
• For a street, project, or classification not individually listed, request written confirmation from the RDO rather than assuming a nearby figure applies.
• For an active transaction, have the computation reviewed by the handling notary, broker, or a tax professional before paying — errors here affect eCAR issuance and title transfer timelines.

Frequently Asked Questions

Is BIR zonal value the same as market value?

No. Zonal value is a government tax benchmark set per zone or barangay; actual market value depends on a specific unit’s condition, floor, view, and current demand, and can be higher or lower than the zonal figure for that area.

Who sets the BIR zonal value?

The Bureau of Internal Revenue proposes zonal values, which are then approved by the Secretary of Finance. Under RA 12001, this authority is transitioning toward a unified Schedule of Market Values developed by local assessors and reviewed by the Bureau of Local Government Finance.

Can I check zonal value online without visiting the BIR?

Yes, the official schedules are published at bir.gov.ph/zonal-values, organized by Revenue Region and RDO. For a transaction with real money at stake, confirm the figure with the RDO directly, since third-party lookup tools may not reflect the latest published schedule.

What if my property’s street isn’t listed in the zonal value schedule?

Some schedules apply a default or general classification for barangays where not every street is individually listed. If you cannot find a clear match, request a certification from the RDO with jurisdiction over the property rather than estimating from a nearby street.

Does zonal value affect real property tax (amilyar)?

Real property tax is computed on the assessed value set by the local assessor, not directly on BIR zonal value, although both are ultimately meant to reflect market conditions. This guide covers zonal value for national taxes; if you want the property tax computation itself, see our related guide on real property tax rates and deadlines once published.

Will BIR zonal values disappear because of RA 12001?

Over time, yes — the law directs a transition to a single Schedule of Market Values per LGU that is meant to replace separate zonal and assessor valuations. Existing zonal values remain in force in a given locality until its updated SMV is approved and takes effect, so both systems are expected to coexist during the transition.

Is the higher of zonal value or selling price always used?

For capital gains tax and documentary stamp tax on a capital-asset sale, yes — the BIR uses the higher of the gross selling price, the zonal value, and the assessor’s fair market value. Donor’s tax and estate tax use similar fair-market-value comparisons but involve additional deductions and exemptions specific to those taxes.

What to Do Next

If you’re preparing to sell, donate, or transfer inherited property, start by identifying the correct RDO for the property’s address and pulling its current zonal value schedule from bir.gov.ph/zonal-values. Then compare that figure against the assessor’s fair market value on the tax declaration and the price you intend to declare in the deed, since the BIR will use whichever of the three is highest. For anything beyond a rough estimate, have a notary, broker, or accountant confirm the computation before you pay capital gains tax, documentary stamp tax, or file for an eCAR.

Figures in this article reflect published BIR, legal, and tax-reference sources as of August 21, 2026, and rates cited (6% capital gains tax, 1.5% documentary stamp tax, 6% donor’s and estate tax) are general national rates that do not account for exemptions, deductions, or property-specific classifications. Property valuation rules are actively transitioning under RA 12001 as of this writing — always confirm the currently applicable value and rate with the BIR or a licensed tax professional before a transaction.
