BIR Form 1801 – Estate Tax Return

A BIR Form 1801 – Estate Tax Return in the Philippines reports the income, deductions and tax due to the revenue authority for the period it covers.

BIR Form 1801 must be filed and the estate tax paid within one year from the date of death of the decedent under Section 90(B) of the NIRC. The BIR Commissioner may, in meritorious cases, extend the filing period up to 30 days. For decedents who died before the TRAIN Law took effect (before January 1, 2018), the graduated rates under the old NIRC apply — heirs of pre-TRAIN Law decedents who have not yet filed BIR Form 1801 may be entitled to an estate tax amnesty under Republic Act No. 11213 (Estate Tax Amnesty Act), as extended by Republic Act No. 11569 (2021) through June 2023, at a flat 6% amnesty rate.

The net taxable estate for Philippine estate tax purposes is the gross estate less authorized deductions under Section 86 of the NIRC. The TRAIN Law standard deductions are: PHP 5,000,000 standard deduction (applicable to all estates regardless of citizenship); PHP 10,000,000 family home deduction (for the decedent's family home, as certified by the Barangay Captain); deduction for retirement benefits from approved private benefit plans under RA 4917; claims against the estate; unpaid mortgages; taxes accrued before death; losses from casualty during settlement period; and medical expenses within one year of death.

For non-resident alien decedents, Philippine estate tax applies only to property situated in the Philippines (Philippine-situs property), with deductions proportional to the Philippine estate's ratio to the worldwide gross estate. Estate tax must be fully paid and a BIR Estate Tax Clearance obtained before the Register of Deeds will process the transfer of real property from the estate to heirs, and before banks will release the decedent's deposits to the estate.

The legal framework governing the BIR Form 1801 – Estate Tax Return in Philippines draws on several key statutes and regulatory bodies. Under Philippine law, the Civil Code of the Philippines (Republic Act No. 386) governs contractual obligations. The Revised Corporation Code (Republic Act No. 11232) regulates corporate entities through the Securities and Exchange Commission (SEC). The Labor Code of the Philippines (Presidential Decree No. 442) and Department of Labor and Employment (DOLE) govern employment matters. The Data Privacy Act of 2012 (Republic Act No. 10173) and the National Privacy Commission (NPC) protect personal data. The Bureau of Internal Revenue (BIR) administers tax obligations under the National Internal Revenue Code. Parties executing a BIR Form 1801 – Estate Tax Return in Philippines should confirm the document reflects current law, including any amendments enacted since the original drafting date. The National Internal Revenue Code (RA 8424) sets the foundational requirements.

BIR Form 1801 must be filed within 1 year from the date of death of a Philippine resident decedent or a non-resident alien with Philippine-situs property.

BIR Form 1801 is required when a decedent owned real property in the Philippines — house and lot, agricultural land, commercial property, or condominium units. The heirs cannot register the transfer of title to the inherited real property at the Registry of Deeds without the BIR Estate Tax Clearance issued after BIR Form 1801 is filed and estate tax is paid.

BIR Form 1801 is required when the decedent held bank accounts, investments, shares of stock, or other financial assets. Banks in the Philippines are prohibited under Section 97 of the NIRC from allowing withdrawal of the decedent's deposits exceeding PHP 20,000 without a BIR certification that the estate tax has been paid — BIR Form 1801 filing is the prerequisite for obtaining this certification.

BIR Form 1801 is required for the estate of a non-resident alien decedent who owned real property, shares in Philippine corporations, franchises, or other Philippine-situs assets at the time of death — Philippine estate tax applies to all Philippine-situs property regardless of the decedent's citizenship or place of death.

BIR Form 1801 is required even if the estate owes zero estate tax — for example, when all estate assets are below the PHP 5,000,000 standard deduction threshold. A nil or zero estate tax return must still be filed to obtain the BIR Estate Tax Clearance needed for asset transfers.

BIR Form 1801 is required for unsettled estates of decedents who died years ago — the estate cannot be judicially or extrajudicially settled and heirs cannot receive their inheritance without first settling the estate tax, including penalties for late filing.

A complete BIR Form 1801 for the Philippines must include the following schedules and information for accurate estate tax computation and clearance.

Decedent Information: Full legal name, TIN, date of birth, date of death, citizenship, civil status, and last address of the deceased. Whether the decedent was a Philippine resident or non-resident alien determines the scope of assets includible in the gross estate.

Estate Administrator/Executor: Name, TIN, and address of the estate's administrator or executor appointed by the Regional Trial Court (for judicial settlement) or the heir filing the return (for extrajudicial settlement). The administrator is personally liable for the estate tax until settlement.

Gross Estate: Schedule of all assets owned by the decedent at time of death, categorized as: real property (with TCT/CCT numbers, BIR zonal values, assessed values); personal property (bank accounts, vehicles, jewelry, shares of stock); intangible personal property (franchises, patents, royalties); and transfers in contemplation of death or with retained interest under Section 85 of the NIRC. Real property is valued at the higher of BIR zonal value or assessor's FMV per the latest Real Property Tax Declaration.

Deductions: Itemized allowable deductions under Section 86 of the NIRC: PHP 5,000,000 standard deduction; family home deduction (up to PHP 10,000,000, supported by Barangay Certification); claims against the estate (loans, mortgages on Philippine property); unpaid taxes due before death; medical expenses within 1 year of death (up to PHP 500,000); and retirement benefits under RA 4917.

Net Taxable Estate and Tax Due: Gross estate less total deductions equals net taxable estate. Estate tax = 6% of net taxable estate (or zero if net estate is negative or zero). Payment at the Authorized Agent Bank or BIR online channels within 1 year from death (or within the extended period if approved by the Commissioner).

Installment Payment Option: Under Section 91(B) of the NIRC, the estate tax may be paid in 2 years from the statutory deadline if immediate payment would impose undue hardship — subject to BIR Commissioner approval and a 25% surcharge on unpaid balance if not timely settled.
