What Happens to a Sole Proprietor's BIR Registration When the Owner Dies?

When a sole proprietor dies, their BIR registration does not pass to their heirs — it ends with them. The business’s Taxpayer Identification Number (TIN), books of accounts, and Certificate of Registration stay tied to the deceased individual. If the heirs want the business to continue, the estate must register as its own taxpayer under BIR Form 1904 (and BIR Form 1901 if it keeps operating), and every filing from the date of death forward — 1701Q, 2551Q or 2550Q, and 1604 alphalist entries — moves onto the estate’s own TIN.

Does a sole proprietor’s BIR registration end automatically when the owner dies? #

Yes — a sole proprietorship’s BIR registration is personal to the individual who owns it, and death ends that registration; it does not pass by inheritance the way a bank account or a piece of land does. A surviving spouse or child cannot simply keep issuing receipts or filing returns under the deceased owner’s TIN, even if they physically keep the sari-sari store or online shop running the very next day.

This is a direct consequence of how the Philippine Tax Code treats income earned after death. Under NIRC Section 60(A)(3), as amended, income received during the period of administration or settlement of an estate is taxed to the estate itself, as a distinct taxpayer from the person who died. Section 60(A) of the National Internal Revenue Code, as reproduced by the Tax and Accounting Center, Inc., includes among the categories of income subject to fiduciary taxation:

“Income received by estates of deceased persons during the period of administration or settlement of the estate[.]”

That single clause is why the business cannot simply keep running invisibly under the old TIN after the owner dies — the law already treats post-death business income as belonging to a different taxpayer, the estate, from day one. For the broader framework this clause sits inside, see How Are Trusts and Estates Under Administration Taxed by the BIR? Fiduciary Income Tax Under NIRC Sections 60–66.

What happens to the deceased owner’s TIN, Certificate of Registration, and books of accounts? #

The deceased owner’s individual TIN is not deleted, but it is retired and tagged as belonging to a deceased taxpayer — it is never reused or reassigned, even to an heir who takes over the same business. The Certificate of Registration (BIR Form 2303) issued under that TIN, along with any unused receipt or invoice booklets and previously registered books of accounts, stays attached to the retired TIN and cannot be relabeled for the estate.

The mechanics of retiring the TIN run through the same multi-purpose registration-update form used for other changes:

• The executor, administrator, or an heir with legal authority files BIR Form 1905 at the RDO where the deceased was registered, checking the box for TIN cancellation due to death.
• Supporting documents typically include the decedent’s death certificate and, where the filer is not a court-appointed executor or administrator, proof of the heir’s authority to act (such as an extrajudicial settlement document).
• Once processed, the RDO tags the TIN as belonging to a deceased taxpayer, closing out the tax types and registered receipts tied to it.

How do heirs register the estate to keep the business running? #

Registering the estate is a two-step process: first securing the estate’s own TIN as a one-time taxpayer, then separately registering it as an entity engaged in trade or business if the heirs intend to keep operating it. Skipping either step leaves the business with no valid registration to issue receipts or file returns under.

1. Secure the estate’s TIN using BIR Form 1904, filed at the RDO with jurisdiction over the decedent’s residence at the time of death (or, for a nonresident decedent, the RDO of the executor or administrator), attaching the death certificate.
2. If the business will continue operating, additionally file BIR Form 1901 to register the estate as a taxpayer engaged in trade or business — the same form category historically used for estates and trusts — covering the sari-sari store, online-selling activity, or other line of business, under the estate’s new TIN.
3. Register new books of accounts, invoices, and receipts under the estate’s TIN; the deceased owner’s previously registered books do not transfer.
4. Identify the return filer correctly. BIR Form 1701 guidance for estates engaged in trade or business calls for the taxpayer name to read “ESTATE of [First Name, Middle Name, Last Name]” rather than the decedent’s own name, so the return is unmistakably filed by the estate as fiduciary, not by the deceased individual.

Separately, and on its own one-year clock from the date of death, the estate (transfer) tax itself is computed and paid using BIR Form 1801 — a one-time tax on the value of everything the decedent owned at death, distinct from the ongoing income tax and business-tax registration covered here. See How to Compute Philippine Estate Tax: A Step-by-Step Worked Example Under the TRAIN Law for that computation.

One procedural relief no longer applies: the old requirement to file a separate “Notice of Death” with the BIR within two months of death, formerly under NIRC Section 89, was repealed by the TRAIN Law (Republic Act No. 10963). Heirs today proceed straight to estate registration and the BIR Form 1801 estate tax return rather than filing a preliminary notice first.

What happens to the decedent’s own, unfinished-year income tax? #

Income the deceased owner earned from January 1 up to the date of death is still reported under their own individual TIN, on a final BIR Form 1701 covering that shortened period — it does not move to the estate. Only income earned from the date of death onward shifts to the estate as a separate taxpayer under NIRC Section 60(A)(3).

In practice, this means the executor, administrator, or an heir files the decedent’s last individual annual income tax return on their behalf, reporting business and other income for the stub period ending on the date of death, using the decedent’s own TIN one final time. This return is separate from, and filed independently of, the BIR Form 1801 estate tax return on the value of the estate itself.

How should DAT-file and quarterly filings split at the date of death? #

Filings that cover a period entirely before the date of death stay filed under the individual TIN and are not reopened; filings for any period from the date of death onward belong to the estate’s TIN once it is registered. The clean cases are whole quarters — a 2551Q or 1701Q for a quarter that closed before the owner died is simply the individual’s last quarterly return, filed as normal.

The harder case is the quarter in which death actually falls, since BIR percentage tax, VAT, and quarterly income tax returns are not designed with a mid-quarter change of taxpayer in mind. There is no single BIR issuance that spells out a mechanical formula for splitting a partial quarter this way; in practice, the individual TIN’s share of that quarter (up to the date of death) and the estate’s share (from the date of death forward) should be worked out with the RDO once the estate’s TIN is active, rather than assumed. What is clear and grounded in NIRC Section 60(A)(3) is the underlying boundary: pre-death income belongs to the individual, post-death income belongs to the estate. The same boundary carries through to:

• 1604 alphalist entries — payees and payments recorded before death stay under the individual TIN’s alphalist; payments made or received after death are recorded under the estate’s TIN.
• RELIEF, SAWT, and QAP DAT files — sales and purchase listings, and summary alphalists of withholding, split the same way by transaction date relative to the date of death.
• Withholding certificates (BIR Form 2307) issued to or by the business — a certificate covering income paid before death names the individual; one for income paid after the estate takes over names the estate.

A worked example: a sari-sari store owner and online seller who dies in Q2 2026 #

Juan dela Cruz runs a small sari-sari store and sells overruns through an online marketplace, registered as a non-VAT percentage taxpayer under his individual TIN. He dies unexpectedly on April 20, 2026 — partway through the April–June quarter — leaving his spouse to decide whether to continue the business.

Juan’s Q1 2026 returns were already filed in April before his death and are not touched. His spouse, acting as administrator, files BIR Form 1905 to have Juan’s TIN tagged as deceased, then registers the estate’s own TIN under BIR Form 1904 and, since she continues running the store and the online shop, registers the estate as a business under BIR Form 1901 — securing new books of accounts and receipt booklets before issuing another sale in the estate’s name. Sales made April 21 onward go through the estate’s TIN; sales made April 1–20 stay part of Juan’s final individual return.

How is this different from simply closing the business voluntarily? #

Death and voluntary closure both end a registration, but death is procedurally heavier because there is no living registrant left to sign the closure paperwork — the business’s fate depends on estate settlement and the heirs’ choices, not a single retirement filing. RMC No. 47-2026: How to Close or Cancel Your BIR Business Registration covers the voluntary case: a taxpayer who is retiring from business while still able to file BIR Form 1905 for closure themselves, surrender their Certificate of Registration, and settle final returns and liabilities in one relatively streamlined process.

Death removes that option entirely. There is no retirement election to make — the individual taxpayer simply ceases to be able to file anything, the heirs must first establish who has authority to act (an executor under a will, a court-appointed administrator, or heirs under an extrajudicial settlement), and only then can registration matters proceed, running in parallel through TIN cancellation for the decedent, estate tax on the transfer itself, and, if the business continues, a fresh registration for the estate. Voluntary closure ends a registration; death forks it into a closed individual registration and, potentially, a brand-new estate registration.

Frequently asked questions #

Does a sole proprietor’s BIR registration automatically transfer to their heirs when they die? #

No. A sole proprietorship is registered to a single individual’s Taxpayer Identification Number, and that registration does not carry over to a spouse, child, or other heir by operation of death. If the heirs want to keep the business running, they must register the decedent’s estate with the BIR as its own taxpayer, under NIRC Sections 60 to 66, which treat an estate under administration or settlement as a separate taxable entity from the individual who died.

What BIR form is used to register the estate of a deceased sole proprietor? #

The estate first secures its own Taxpayer Identification Number using BIR Form 1904, the application for one-time taxpayers, filed at the Revenue District Office with jurisdiction over the decedent’s residence at the time of death, together with a copy of the death certificate. If the heirs will continue operating the business under the estate, they additionally file BIR Form 1901 to register the estate as an entity engaged in trade or business — the same form category used for estates and trusts — covering the store, invoices, receipts, and books of accounts under the estate’s new TIN.

What happens to the deceased sole proprietor’s original TIN? #

It is retired, not reused. The heirs or executor file BIR Form 1905 with the RDO to have the decedent’s TIN tagged as belonging to a deceased taxpayer, which closes out the tax types registered under that TIN. A Philippine TIN is issued to one person for life and is never reassigned or transferred to another taxpayer, including an heir who takes over the business.

Do quarterly returns filed before the owner’s death need to be refiled under the estate’s TIN? #

No. Percentage tax, VAT, and quarterly income tax returns already filed for periods before the date of death remain valid filings under the deceased owner’s individual TIN and are not amended or transferred. Only the reporting period from the date of death forward — including the stub portion of the quarter in which death occurred — needs to move to the estate’s TIN once it is registered.

Is a sole proprietor’s death treated the same as voluntarily closing a business under RMC No. 47-2026? #

No. RMC No. 47-2026 streamlines the documentary requirements for a taxpayer who chooses to retire from business, cease operations, or transfer ownership voluntarily while still alive to sign the closure paperwork themselves. Death is a different and more procedurally complex trigger: there is no living registrant to file a closure request, the business’s continuation depends on estate settlement and who the heirs are, and the transition runs through estate registration under NIRC Sections 60 to 66 rather than a simple retirement filing.

Does the estate need its own books of accounts, invoices, and receipts, or can it use the deceased owner’s? #

The estate needs its own registered books of accounts, invoices, and receipts under its own TIN once BIR Form 1901 registration is complete. The deceased owner’s previously registered books and unused receipt booklets stay tied to the individual TIN being retired and cannot be carried over or relabeled for the estate’s use.

Summary #

A sole proprietor’s death is a registration break, not a handover: the individual TIN, Certificate of Registration, and books of accounts stop with the person who died and get formally retired through BIR Form 1905, while the estate — if the heirs continue the business — starts fresh with its own TIN under BIR Form 1904 and, where trade or business continues, its own BIR Form 1901 registration, books, and receipts. Filings split cleanly at the date of death under NIRC Section 60(A)(3): everything before stays on the individual’s record, everything after belongs to the estate, with the quarter of death itself needing direct coordination with the RDO since no single issuance spells out the mid-quarter mechanics. That procedural weight is exactly what sets death apart from a simple, voluntary business closure under RMC No. 47-2026 — one is an election a living taxpayer makes, the other is a legal transition the heirs must carry out.
