In the Philippine legal and tax landscape, the transfer of real property is governed by a dual-layered system of national and local taxation. Understanding the basis for computing these taxes is critical for both sellers and buyers to ensure compliance with the National Internal Revenue Code (NIRC) and the Local Government Code (LGC).

The "Higher Of" Rule: The Statutory Tax Base

The foundational principle for computing almost all land-related taxes in the Philippines is the determination of the Tax Base. Unlike other jurisdictions where the actual transaction price is the sole basis, Philippine law requires the use of the highest among three values:

Gross Selling Price (GSP): The total consideration stated in the Deed of Absolute Sale.
Zonal Value (ZV): The fair market value of the land as determined by the Commissioner of Internal Revenue (Bureau of Internal Revenue).
Assessed Value (AV): The fair market value as shown in the schedule of values of the Provincial or City Assessor’s Office.

The mathematical representation of the Tax Base is: $$Tax\ Base = \max(GSP, ZV, AV)$$

National Internal Revenue Taxes

1. Capital Gains Tax (CGT)

CGT is imposed on the "presumed gain" realized by a seller from the sale, exchange, or disposition of real property classified as a capital asset. It is a final tax, meaning it is not subject to further adjustment regardless of the actual profit or loss.

Rate: $6%$
Formula: $$CGT = 0.06 \times Tax\ Base$$
Liability: Usually borne by the Seller, though contractual agreements may shift the payment burden.
Deadline: Must be filed and paid within 30 days from the date of notarization of the Deed of Sale.

2. Documentary Stamp Tax (DST)

DST is an excise tax on the documents, instruments, and papers evidencing the transfer of property.

Rate: $1.5%$
Formula: $$DST = 0.015 \times Tax\ Base$$
Liability: Traditionally paid by the Buyer, unless otherwise agreed upon.
Deadline: Due by the 5th day of the month following the date of notarization (for manual filing) or as prescribed under the Electronic Filing and Payment System (eFPS).

Local Government Taxes and Fees

1. Local Transfer Tax

This is a tax imposed by the province or city on the sale, donation, or any other mode of transferring ownership of real property.

Rate: Varies by location.
- Provinces: Not exceeding $0.50%$ (or $1/2$ of $1%$).
- Cities (within Metro Manila and others): Generally up to $0.75%$ (or $3/4$ of $1%$).
Basis: The same "Higher Of" Tax Base used for CGT and DST.
Deadline: Within 60 days from the date of the execution of the deed.

2. Registration Fees

To finalize the transfer and obtain a new Transfer Certificate of Title (TCT), the buyer must pay registration fees to the Land Registration Authority (LRA) through the Registry of Deeds.

Basis: Graduated scale based on the Tax Base.
Approximate Rate: Roughly $0.25%$, though specific LRA tables apply for different valuation brackets.

Exceptions and Special Classifications

Ordinary Assets vs. Capital Assets

The $6%$ CGT only applies to Capital Assets (properties not used in business). If the property is an Ordinary Asset (e.g., owned by a real estate developer or used in trade), the following apply instead:

Creditable Withholding Tax (CWT): Ranging from $1.5%$ to $6%$ depending on whether the seller is habitually engaged in real estate.
Value-Added Tax (VAT): $12%$ of the selling price or FMV, applicable if the seller is VAT-registered or if the property exceeds the current threshold (typically $\approx$ ₱3.2 Million for residential dwellings).
Income Tax: The gain is included in the seller's gross income and taxed at graduated rates (for individuals) or corporate rates.

Principal Residence Exemption

A seller may be exempt from the $6%$ CGT if the property sold is their principal residence, provided the proceeds are fully utilized to acquire or construct a new principal residence within 18 months, and the BIR is notified within 30 days. This exemption is only available once every 10 years.

Legislative Updates: EOPT and RPVARA (2024-2026)

The tax landscape has been recently streamlined by two major acts:

Ease of Paying Taxes (EOPT) Act (RA 11976): Since 2024, the "File-and-Pay Anywhere" rule allows taxpayers to settle CGT and DST at any Authorized Agent Bank or RDO, eliminating the "wrong venue" surcharge.
Real Property Valuation and Assessment Reform Act (RPVARA - RA 12001): This law mandates a Single Valuation Base to eventually eliminate the discrepancy between BIR Zonal Values and Local Assessor Values. By 2026, the transition toward a unified "Market Value" aims to simplify the computation basis into a single, transparent figure.

Tax/Fee	Rate	Basis
Capital Gains Tax	$6%$	Higher of GSP, ZV, or AV
Documentary Stamp Tax	$1.5%$	Higher of GSP, ZV, or AV
Local Transfer Tax	$0.5% - 0.75%$	Higher of GSP, ZV, or AV
Registration Fees	Graduated ($\approx 0.25%$)	Higher of GSP, ZV, or AV
Notarial Fees	Negotiable ($1% - 2%$)	Agreed Contract Price
