Can the BIR Look Into Your Bank Account? NIRC Section 6(F) Bank Deposit Inquiry Explained

The BIR cannot freely inspect a taxpayer’s bank account. Republic Act No. 1405 treats deposits as confidential, and NIRC Section 6(F), as amended by Republic Act No. 10021, lets the Commissioner of Internal Revenue inquire into bank deposits in three situations: a decedent’s gross estate, a taxpayer’s compromise application based on financial incapacity (with a written waiver), and a foreign tax authority’s treaty request.

What does the Bank Secrecy Law say? #

Republic Act No. 1405, approved September 9, 1955, declares deposits with banks and banking institutions in the Philippines to be of an absolutely confidential nature. It lists a short set of exceptions, and NIRC Section 6(F) adds a tax-specific exception on top of them. Section 2 of the law reads, in relevant part:

“All deposits of whatever nature with banks or banking institutions in the Philippines including investments in bonds issued by the Government of the Philippines, its political subdivisions and its instrumentalities, are hereby considered as of an absolutely confidential nature and may not be examined, inquired or looked into by any person, government official, bureau or office, except upon written permission of the depositor, or in cases of impeachment, or upon order of a competent court in cases of bribery or dereliction of duty of public officials, or in cases where the money deposited or invested is the subject matter of the litigation.”

— Republic Act No. 1405, Section 2 (LawPhil)

The phrase “government official, bureau or office” is why the BIR’s ordinary audit powers do not by themselves reach deposit records. A footnote on the LawPhil copy notes that Section 2 was later amended by Presidential Decree No. 1792 and that the decree was expressly repealed by Republic Act No. 7653; the quoted wording is the original text.

What does NIRC Section 6(F) provide? #

NIRC Section 6(F), titled “Authority of the Commissioner to Inquire into Bank Deposit Accounts and Other Related Information Held by Financial Institutions,” overrides bank secrecy laws for a defined list of taxpayers. Republic Act No. 10021, the Exchange of Information on Tax Matters Act of 2009, approved March 8, 2010, amended it to its current form. The operative text states:

“Notwithstanding any contrary provision of Republic Act No. 1405, Republic Act No. 6426, otherwise known as the Foreign Currency Deposit Act of the Philippines, and other general and special laws, the Commissioner is hereby authorized to inquire into the bank deposits and other related information held by financial institutions of: (1) A decedent to determine his gross estate. (2) Any taxpayer who has filed an application for compromise of his tax liability under Sec. 204 (A)(2) reason of financial incapacity to pay his tax liability.”

— NIRC Section 6(F), as amended by Republic Act No. 10021, Section 3 (LawPhil)

The same paragraph adds a third category, in clause (3): a specific taxpayer or taxpayers who are the subject of a request for tax information from a foreign tax authority under an international convention or agreement on tax matters to which the Philippines is a signatory or party. The three situations compare as follows.

How does the waiver work for a compromise application? #

A taxpayer who asks the BIR to compromise an assessment because of financial incapacity must waive bank secrecy in writing before the application is considered. The waiver itself is what authorizes the Commissioner to inquire into the taxpayer’s deposits, so the inquiry follows from the taxpayer’s own request for relief. Section 6(F) states:

“In case a taxpayer files an application to compromise the payment of his tax liabilities on his claim that his financial position demonstrates a clear inability to pay the tax assessed, his application shall not be considered unless and until he waives in writing his privilege under Republic Act No. 1405, Republic Act No. 6426, otherwise known as the Foreign Currency Deposit Act of the Philippines, or under other general or special laws, and such waiver shall constitute the authority of the Commissioner to inquire into the bank deposits of the taxpayer.”

— NIRC Section 6(F), as amended by Republic Act No. 10021 (LawPhil)

The text ties this clause to Section 204(A)(2), the financial-incapacity ground. For how the compromise itself works, including the minimum percentages for each ground, see BIR compromise settlement under Section 204. Applying for a compromise is voluntary, and a taxpayer who would rather not open deposit records can choose a different route to resolve the assessment.

How does Section 6(F) apply to a decedent’s estate? #

For a decedent, Section 6(F)(1) allows the Commissioner to inquire into the deceased person’s bank deposits for one stated purpose: determining the gross estate. The authority is tied to estate tax computation and does not reach the accounts of heirs or other living taxpayers. The gross estate is the starting figure for the estate tax return; the filing steps are covered in BIR Form 1801, the estate tax return.

Worked example: two taxpayers, two outcomes #

The examples below are fictional and use round numbers to show where Section 6(F) applies and where it does not.

1. Compromise applicant. Ms. Reyes, a sole proprietor, receives a final assessment of PHP 2,400,000 and files a compromise application claiming that her finances show a clear inability to pay. Under Section 6(F), her application is not considered until she signs a written waiver of her privilege under Republic Act No. 1405 and Republic Act No. 6426. The signed waiver is the Commissioner’s authority to inquire into her deposits.
2. Audit taxpayer. Mr. Santos receives a Letter of Authority for taxable year 2024 and has filed no compromise application. Section 6(F) does not list his situation, so the audit proceeds on his books and records. His deposit records would remain under Republic Act No. 1405 unless he gives written permission or another exception applies. The audit process is explained in what a BIR Letter of Authority is and what your rights are during an audit.

What about Republic Act No. 10365 and other bank-inquiry rules? #

Republic Act No. 10365, signed in February 2013, amended the Anti-Money Laundering Act (Republic Act No. 9160), not the NIRC. Inquiries into deposits for money-laundering purposes run through the Anti-Money Laundering Council under that separate law, which is outside Section 6(F). Press coverage at the time described RA 10365 as allowing the Council to look into the accounts of suspected money launderers, a power distinct from the BIR’s tax-administration authority. This article does not cover that regime in detail.

On procedure, this article does not cite a specific Revenue Regulation or Revenue Memorandum Order on bank-inquiry steps, because none was confirmed against a primary source while researching it. A taxpayer facing a request for bank records should ask the BIR office to state the legal basis in writing and consult a tax professional.

Summary #

NIRC Section 6(F), as amended by Republic Act No. 10021, is a narrow exception to the Bank Secrecy Law. It covers a decedent’s deposits (to determine the gross estate), the deposits of a compromise applicant who claims financial incapacity and has waived secrecy in writing, and a specific taxpayer named in a treaty-based foreign request. Outside those situations, Section 2 of Republic Act No. 1405 still applies.

Frequently asked questions #

Can the BIR look into my bank account? #

Not freely. Under Republic Act No. 1405, bank deposits are treated as absolutely confidential, and NIRC Section 6(F), as amended by Republic Act No. 10021, creates only specific exceptions: the deposits of a decedent (to determine the gross estate), of a taxpayer who has applied for compromise on the ground of financial incapacity (after a written waiver), and of a specific taxpayer named in a foreign tax authority’s information request under a tax treaty or convention.

What does the waiver in a financial-incapacity compromise application do? #

Section 6(F) provides that an application to compromise tax liabilities on the claim of a clear inability to pay shall not be considered unless and until the taxpayer waives in writing the privilege under Republic Act No. 1405, Republic Act No. 6426, or other general or special laws, and that the waiver constitutes the authority of the Commissioner to inquire into the taxpayer’s bank deposits.

Does Section 6(F) apply to a compromise based on doubtful validity of the assessment? #

The text of Section 6(F) refers to an application for compromise under Section 204(A)(2) by reason of financial incapacity to pay. It does not extend the bank-inquiry authority to a compromise that rests on the doubtful validity of an assessment.

Can the BIR inspect the bank accounts of a deceased person? #

Yes, for a limited purpose. Section 6(F)(1) authorizes the Commissioner to inquire into the bank deposits and other related information held by financial institutions of a decedent to determine his gross estate, the base for the estate tax reported in BIR Form 1801.

Does the Letter of Authority for a tax audit let the BIR see my bank records? #

Section 6(F) does not list a regular audit among the situations that override bank secrecy. A Letter of Authority authorizes an examination of the taxpayer’s books and records, but the bank-inquiry exceptions are the three situations written into Section 6(F) and the exceptions in Section 2 of Republic Act No. 1405.
