In Philippine law, the transfer of real property by inheritance is governed by the National Internal Revenue Code (NIRC) of 1997, as amended, particularly by Republic Act No. 10963 (TRAIN Law), and supplemented by the Civil Code provisions on succession, the Property Registration Decree (Presidential Decree No. 1529), and various Bureau of Internal Revenue (BIR) Revenue Regulations. A pivotal requirement in effecting such transfers is the Electronic Certificate Authorizing Registration (eCAR). This article provides an exhaustive examination of whether an eCAR is mandatory for inherited real estate properties that are under construction, detailing the legal framework, tax implications, valuation rules, procedural requirements, registration process, potential challenges, and related considerations.

I. Legal Definition and Nature of eCAR

The eCAR is an official electronic document issued by the BIR that certifies the full payment of applicable internal revenue taxes on the transfer of real property. It serves as the BIR’s authorization to the Register of Deeds (RD) to register the transfer of title from the decedent to the heirs. Under Revenue Regulations (RR) implementing the eCAR system, the document is generated through the BIR’s electronic platforms and replaces the manual Certificate Authorizing Registration (CAR). Its issuance is a prerequisite for the annotation and issuance of a new Transfer Certificate of Title (TCT) or Condominium Certificate of Title (CCT) in the name of the heir or heirs.

The eCAR is not a tax exemption certificate; it is a clearance that confirms satisfaction of the estate tax liability under Section 84 of the NIRC (as amended) and, where applicable, Documentary Stamp Tax (DST) obligations. Failure to secure an eCAR renders the extrajudicial settlement of estate (EJS) or deed of partition unenforceable against third parties and prevents the RD from registering the inheritance.

II. Inheritance of Real Property Under Philippine Law

Upon the death of a natural person, all property, rights, and obligations constituting the estate pass to the heirs by operation of law (Article 777, Civil Code). Real estate forms part of the gross estate under Section 85 of the NIRC. The estate tax is imposed on the net estate at a flat rate of six percent (6%), computed as of the date of the decedent’s death, irrespective of whether the property is fully constructed, partially constructed, or bare land.

Inherited real estate “under construction” refers to any parcel of land with ongoing improvements—such as a residential house, commercial building, or condominium project—where construction has commenced but has not reached completion or occupancy permit stage at the time of death. The incomplete structure is still classified as real property because it is permanently attached to the land (Article 415, Civil Code). Consequently, both the land and the proportional value of the unfinished improvements are included in the gross estate.

III. Affirmative Requirement of eCAR for Properties Under Construction

Yes, an eCAR is unequivocally required for inherited real estate properties under construction. The obligation stems from the following principles:

Transfer of Ownership Trigger: The transmission of property from the decedent to the heirs constitutes a taxable transfer subject to estate tax. The eCAR is the BIR’s official acknowledgment that this tax has been paid, enabling registration under Section 91 of the NIRC and PD 1529.
No Statutory Exemption Based on Construction Status: Neither the NIRC, TRAIN Law, nor any implementing RR exempts incomplete structures from the eCAR requirement. The law focuses on the fact of transfer, not the degree of physical completion.
Uniform Application to All Real Properties: BIR policy treats all real properties uniformly for estate tax and registration purposes. Whether the property is a finished house and lot, a condominium unit under construction, or raw land with ongoing foundation work, the eCAR remains mandatory.

IV. Valuation of Real Estate Under Construction for Estate Tax Purposes

Valuation is critical because it determines the estate tax base, which in turn affects eCAR issuance.

Date of Valuation: Fair market value (FMV) is fixed at the time of death (Section 88, NIRC). Subsequent construction progress after death does not retroactively alter the tax base.
Basis of Valuation:
- Land: Higher of (a) BIR zonal value or (b) FMV per the latest tax declaration.
- Improvements Under Construction: The value of the partially completed structure is included based on the cost of materials, labor, and other expenses incurred up to the date of death, or the appraised value by a BIR-accredited appraiser if higher. Supporting documents such as construction contracts, progress billings, permits, and engineering reports are required.
- Schedule of Market Values (SMV): Local government units’ SMV for buildings may be used, adjusted for the percentage of completion.
BIR Appraisal: In cases of substantial unfinished improvements, the BIR Regional Office may conduct an ocular inspection or require an independent appraisal to prevent undervaluation.

The estate tax return (BIR Form No. 1801) must include a detailed schedule of real properties, with separate descriptions for land and improvements under construction.

V. Procedural Steps to Secure an eCAR for Inherited Properties Under Construction

The process follows a standardized sequence under current BIR regulations:

Preparation and Filing of Estate Tax Return: Within one year from death (or extended period if granted), the executor, administrator, or any heir files BIR Form No. 1801, attaching:
- Death certificate
- Certified true copy of title
- Tax declaration
- Construction documents (building permit, as-built plans or progress reports, sworn statement of construction cost up to date of death)
- Proof of payment of local transfer taxes (if already paid)
Payment of Estate Tax: Full payment is required before eCAR issuance, unless a valid installment payment arrangement under Section 91 of the NIRC is approved.
Payment of Documentary Stamp Tax (DST): DST on the transfer by inheritance is imposed at P15.00 per P1,000.00 of the FMV (or consideration, whichever is higher) under Section 196 of the NIRC.
Issuance of eCAR: Upon verification and full payment, the BIR generates the eCAR electronically. Multiple eCARs may be issued if the property is partitioned among several heirs.
Registration with the Registry of Deeds: The EJS or deed of partition, together with the eCAR, is presented to the RD. The RD annotates the title and issues new titles in the heirs’ names. For properties under construction, the RD may note the incomplete status on the title until a final survey or completion report is submitted.

VI. Related Taxes and Fees Beyond Estate Tax

Local Transfer Tax: Imposed by the city or municipality (usually 0.5% to 1% of FMV) and payable to the local treasurer before RD registration.
Real Property Tax (RPT): Accrued RPT up to the date of death must be settled; post-death RPT becomes the heirs’ liability.
Other Charges: Notarial fees, RD registration fees, and barangay clearance fees.

All these must be cleared, but only the BIR taxes are covered by the eCAR.

VII. Common Challenges and Practical Considerations Specific to Properties Under Construction

Incomplete Documentation: Heirs often lack precise records of construction costs at the exact date of death, leading to BIR requests for additional affidavits or appraisals.
Ongoing Construction Post-Death: Heirs may continue building; however, the estate tax liability is locked at the date-of-death value. Any increase in value after death is not subject to additional estate tax but may affect future capital gains tax if sold.
Financing and Liens: If construction was financed by a bank loan secured by the property, the mortgage must be addressed or assumed by heirs before clear title transfer.
Multiple Heirs and Partition: If the property is indivisible or construction is at a sensitive stage, court approval for partition may be needed, further delaying eCAR utilization.
Electronic Filing Mandate: All estate tax returns and eCAR applications are processed through the BIR’s electronic system; manual filing is no longer accepted in most Revenue District Offices.
Penalties for Non-Compliance: Surcharges (25% or 50%), interest (12% per annum), and possible criminal liability for tax evasion apply for late filing or underdeclaration.

VIII. Relevant Legal and Regulatory Framework

NIRC Provisions: Sections 84–104 (estate tax), Section 196 (DST), Section 91 (eCAR issuance).
TRAIN Law (RA 10963): Introduced the 6% flat estate tax rate and simplified procedures.
Property Registration Decree (PD 1529): Mandates RD registration supported by eCAR.
Civil Code: Articles 774–1105 (succession) and 415 (classification of property).
BIR Revenue Regulations: Those governing estate tax returns, eCAR generation, and valuation of real properties (including improvements).

No provision in the foregoing exempts or waives the eCAR for properties under construction. The requirement is absolute once the property forms part of a taxable estate and is the subject of a title transfer.

IX. Conclusion

An Electronic Certificate Authorizing Registration (eCAR) is required for inherited real estate properties under construction in the Philippines. The incomplete status of the structure does not alter the fundamental obligation to pay estate tax and secure BIR clearance before registering the inheritance with the Registry of Deeds. Heirs must meticulously document the property’s condition and value as of the date of death, comply with filing and payment timelines, and coordinate with both BIR and RD offices. Proper adherence ensures clean title transfer, avoids penalties, and protects the heirs’ rights over the asset. Failure to obtain the eCAR effectively stalls the legal recognition of ownership, regardless of the property’s construction progress.
