Introduction

In the Philippine tax system, estate tax is imposed on the privilege of transferring the net estate of a decedent to his or her heirs. The Tax Reform for Acceleration and Inclusion (TRAIN) Law, or Republic Act No. 10963, which took effect on January 1, 2018, introduced significant changes to the estate tax regime, including a shift from a progressive tax rate to a flat 6% rate and an increase in the standard deduction to PHP 5 million. However, for decedents who passed away before this date—specifically, prior to January 1, 2018—the computation of estate tax follows the provisions of the National Internal Revenue Code (NIRC) as amended before the TRAIN Law. This article provides a comprehensive overview of the estate tax computation under the pre-TRAIN framework, with a focus on properties inherited by the decedent prior to the law's enactment. It covers the legal basis, components of the gross estate, allowable deductions, tax rates, valuation methods, filing requirements, and related administrative procedures.

The discussion is grounded in Sections 84 to 97 of the NIRC (Republic Act No. 8424, as amended up to Republic Act No. 9224), relevant Bureau of Internal Revenue (BIR) regulations, and jurisprudence from the Supreme Court and Court of Tax Appeals. Understanding this regime is crucial for estates involving properties acquired through inheritance before 2018, as the tax treatment remains tied to the date of the decedent's death.

Legal Basis and Applicability

The estate tax under the pre-TRAIN Law applies to the estates of individuals who died before January 1, 2018. This includes Filipino citizens, resident aliens, and non-resident aliens with property in the Philippines. For non-resident aliens, only properties situated in the Philippines are subject to estate tax.

Properties inherited by the decedent prior to the TRAIN Law are included in the gross estate at their fair market value (FMV) at the time of the decedent's death, regardless of when they were acquired. The key principle is that estate tax is a transfer tax on the right to transmit property upon death, not on the property itself. Thus, even if the property was inherited by the decedent decades earlier, its value forms part of the taxable estate under the old rules if the death occurred pre-2018.

BIR Revenue Regulations (RR) No. 2-2003, as amended, provides guidelines for estate tax computation, emphasizing that the tax is computed on the net estate after deductions. Transitional rules under RR No. 12-2018 clarify that estates of decedents dying before 2018 are not retroactively affected by TRAIN amendments.

Composition of the Gross Estate

The gross estate includes all property, real or personal, tangible or intangible, wherever situated, owned by the decedent at the time of death. For properties inherited prior to TRAIN, the following categories are relevant:

1. Real Property

Includes land, buildings, and improvements. Inherited real properties, such as ancestral homes or agricultural lands, are valued at the higher of the zonal value (as determined by the BIR) or the FMV as assessed by the provincial/city assessor.
Example: If the decedent inherited a parcel of land in 1990 and died in 2015, the land's value in 2015 (e.g., PHP 10 million based on zonal value) is included.

2. Personal Property

Tangible items like vehicles, jewelry, and artworks inherited by the decedent.
Intangible items such as stocks, bonds, bank deposits, and intellectual property rights.

3. Special Inclusions

Transfers in contemplation of death (e.g., donations made within three years before death, presumed to be in anticipation of death unless proven otherwise).
Revocable transfers where the decedent retained control.
Property passing under a general power of appointment.
Proceeds of life insurance where the decedent had incidents of ownership.
For non-resident aliens, only Philippine-situs properties (e.g., shares in Philippine corporations) are included.

Exclusions from the gross estate include separate property of the surviving spouse under the conjugal partnership or absolute community regime, as well as properties already taxed in prior estates if transferred within five years (under the "prior taxation" rule, allowing credit for previously paid taxes).

Valuation of Properties

Valuation is critical for accurate computation, especially for inherited properties whose values may have appreciated over time.

Real Property: Valued at FMV at death, using the BIR zonal value or local assessor value, whichever is higher. If no zonal value exists, appraisal by a BIR-accredited appraiser is required.
Stocks and Securities: Listed stocks at the mean between highest and lowest quotations on the date of death or nearest trading day. Unlisted stocks at book value.
Other Assets: Bank deposits at face value plus interest; receivables at face value less allowance for bad debts.
Foreign Currency Assets: Converted to Philippine pesos using the exchange rate at death.

For inherited properties, historical cost is irrelevant; only current FMV matters. BIR RR No. 6-2013 provides detailed valuation guidelines.

Allowable Deductions

Deductions reduce the gross estate to arrive at the net estate. Under the pre-TRAIN Law, deductions are more varied and limited compared to post-TRAIN simplifications.

1. Ordinary Deductions

Funeral Expenses: Actual expenses up to 5% of the gross estate or PHP 200,000, whichever is lower.
Judicial Expenses: Costs of estate administration, such as attorney's fees and court costs.
Claims Against the Estate: Debts owed by the decedent, provided they are notarized or supported by evidence.
Claims Against Insolvent Persons: If included in gross estate.
Unpaid Mortgages or Taxes: On included properties.
Losses: From fire, storm, etc., not compensated by insurance, occurring after death but before distribution.

2. Special Deductions

Standard Deduction: PHP 1 million (fixed, unlike the PHP 5 million post-TRAIN).
Family Home: Up to PHP 1 million, if the home is the decedent's dwelling and certified as such.
Medical Expenses: Actual expenses incurred within one year before death, up to PHP 500,000, substantiated by receipts.
Retirement Benefits: Exempt if under RA 4917 or similar laws.

For non-resident aliens, deductions are prorated based on the ratio of Philippine gross estate to worldwide gross estate.

Vanishing deduction applies to properties previously taxed (e.g., inherited by the decedent within five years before his death): 100% if within one year, decreasing by 20% per year up to five years.

Computation of Net Estate and Tax Due

The net estate is gross estate minus deductions. The estate tax is then computed using the progressive rates under the pre-TRAIN NIRC:

Net Estate Value (PHP)	Tax Rate	Plus (PHP)
Up to 200,000	Exempt	-
200,001 - 500,000	5%	-
500,001 - 2,000,000	8%	15,000
2,000,001 - 5,000,000	11%	135,000
5,000,001 - 10,000,000	15%	465,000
Over 10,000,000	20%	1,215,000

Formula: Tax = (Rate on excess over bracket) + Base tax from previous bracket.

Example: For a net estate of PHP 3 million (including inherited properties valued at PHP 2 million):

Tax = 11% of (3,000,000 - 2,000,000) + 135,000 = 11% of 1,000,000 + 135,000 = 110,000 + 135,000 = PHP 245,000.

Tax credits are available for estate taxes paid to foreign countries on foreign-situs properties.

Filing and Payment Requirements

The estate tax return (BIR Form 1801) must be filed within six months from death, extendable up to 30 days. Payment is due upon filing, but installment payment may be allowed if the estate lacks liquidity, subject to BIR approval.

For properties inherited prior to TRAIN, if the estate includes illiquid assets like real property, the executor may request payment in kind or deferred payment. Penalties for late filing include 25% surcharge, 20% interest per annum, and compromise penalties.

Extrajudicial settlement requires payment of estate tax before property transfer. BIR certification (CAR - Certificate Authorizing Registration) is needed for transferring titled properties.

Administrative and Judicial Remedies

If the BIR issues a deficiency assessment, the estate may protest within 30 days. Appeals go to the Commissioner, then Court of Tax Appeals, and Supreme Court.

Jurisprudence, such as in CIR v. Pineda (G.R. No. L-22734, 1967), emphasizes strict compliance with deduction substantiation. Cases like Marcos v. Sandiganbayan highlight valuation disputes for inherited assets.

Special Considerations for Inherited Properties

Capital Gains Tax Implications: When heirs sell inherited properties, capital gains tax (6% on gain) applies, but basis is stepped-up to FMV at death.
Donor's Tax Overlap: If the decedent donated the inherited property pre-death, donor's tax may have been paid, but it doesn't affect estate tax.
Estate Planning: Pre-TRAIN, strategies like trusts or life insurance were used to minimize tax, but these must comply with anti-avoidance rules.
Amnesty Programs: The Estate Tax Amnesty under RA 11213 (extended to 2023) allowed settlement of unpaid pre-2018 estate taxes at 6%, but eligibility required no prior payment.

Conclusion

The pre-TRAIN estate tax regime demands meticulous valuation and deduction claims for properties inherited by the decedent, ensuring the net estate accurately reflects transferable wealth. While more complex than the current flat-rate system, it provides opportunities for deductions that can significantly reduce liability. Executors and heirs must adhere to BIR procedures to avoid penalties and facilitate smooth property transfers.
