What Is a Single Proprietorship Affidavit (Philippines)?
A Single Proprietorship Affidavit in the Philippines provides a formal sworn account of the facts it concerns, executed in the manner the law requires for it to be relied on.
The Single Proprietorship Affidavit serves as a supporting document for numerous government and private sector transactions in the Philippines. The Bureau of Internal Revenue (BIR) accepts the affidavit in support of BIR Form 1901 registration applications where the applicant needs to establish that their business is a sole proprietorship rather than a partnership or joint venture for tax classification purposes under Sections 22 and 24 of the National Internal Revenue Code (NIRC, RA 8424). Philippine banks regulated by the Bangko Sentral ng Pilipinas (BSP) under BSP Circular No. 950 (2017) on Anti-Money Laundering Act (AMLA, RA 9160) customer due diligence require the affidavit as part of corporate account opening Know Your Customer (KYC) documents for sole proprietorship accounts.
For government procurement bidding under the Government Procurement Reform Act (RA 9184), the Philippine Government Electronic Procurement System (PhilGEPS) requires a Single Proprietorship Affidavit for sole proprietor bidders as part of Class A eligibility documents. The Implementing Rules and Regulations (IRR) of RA 9184, specifically Section 23.1, lists the required eligibility documents for bidders, and the affidavit substitutes for the corporate Secretary Certificate required from corporations.
The affidavit must be executed under the Rules on Notarial Practice (A.M. No. 02-8-13-SC), with the affiant personally appearing before the commissioned notary who verifies the affiant's identity through competent evidence of identity under Rule II, Section 12, and affixes the notarial certificate with the document number, page number, book number, and series year.
The legal framework governing the Single Proprietorship Affidavit (Philippines) 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 Single Proprietorship Affidavit (Philippines) in Philippines should confirm the document reflects current law, including any amendments enacted since the original drafting date. The Revised Corporation Code (RA 11232, 2019) sets the foundational requirements.
When Do You Need a Single Proprietorship Affidavit (Philippines)?
A Single Proprietorship Affidavit is needed in the Philippines in several specific circumstances where a sole business owner must formally attest to their status.
A Single Proprietorship Affidavit is required when a sole proprietor applies for a corporate bank account with any BSP-supervised bank. Under BSP Circular No. 950 (2017) on AMLA compliance and Know Your Customer (KYC) requirements, banks require sole proprietors to submit a notarized affidavit alongside the DTI Certificate, BIR Form 2303, government-issued ID, and proof of business address.
A Single Proprietorship Affidavit is needed for PhilGEPS registration and government procurement bidding under RA 9184. The Bids and Awards Committee (BAC) of the procuring entity requires the affidavit as part of the eligibility documents package to confirm that the bidder is the sole owner with full legal authority to enter contracts on behalf of the business.
A Single Proprietorship Affidavit is required when a sole proprietor applies for a small business loan from the Small Business Corporation (SB Corp), the Development Bank of the Philippines (DBP), or the Land Bank of the Philippines. These government financial institutions require the affidavit as part of their loan documentation to confirm the borrower's sole ownership and authority over the business assets offered as collateral.
A Single Proprietorship Affidavit is needed when a sole proprietor renews their Mayor's Permit (Business Permit) with the Local Government Unit (LGU) following a business address change, business name amendment, or any change in the ownership structure. Some LGUs require a fresh affidavit when the DTI Certificate has been renewed or reissued.
A Single Proprietorship Affidavit is required for export permit applications with the Bureau of Export Trade Promotion (BETP) or import permit applications with the Bureau of Customs (BOC) where the importer/exporter is a sole proprietor.

}Frequently Asked Questions
Philippine banks regulated by the Bangko Sentral ng Pilipinas (BSP) require a Single Proprietorship Affidavit as part of their Know Your Customer (KYC) process under BSP Circular No. 950 (2017), which implements the Anti-Money Laundering Act (AMLA, RA 9160, as amended by RA 11521). The affidavit serves multiple purposes: it confirms that the account applicant is the actual sole owner of the business (not a nominee or front for another party), it establishes the legal capacity of the individual to enter contracts on behalf of the business, and it creates a sworn record of ownership that the bank can rely on in compliance examinations by the BSP's Financial Supervision Sector. Without a notarized affidavit, banks cannot open a business account in the trade name of a sole proprietor — they would instead open only a personal savings account, which is unsuitable for business transactions requiring official receipts and invoicing under BIR Revenue Regulations.
Yes, a Single Proprietorship Affidavit must be notarized before a commissioned Notary Public in the Philippines to be legally effective for the purposes for which it is typically used. The affidavit is an instrument executed under oath, and the notarial act attests to the affiant's identity, personal appearance, and the voluntariness of the oath, under the Rules on Notarial Practice (A.M. No. 02-8-13-SC, as amended). The Bureau of Internal Revenue (BIR), Philippine banks, the PhilGEPS procurement portal, and government financial institutions such as the Small Business Corporation (SB Corp) and Development Bank of the Philippines (DBP) all require a notarized affidavit. An unnotarized affidavit is a private document and does not carry the presumption of authenticity that a public instrument — such as a notarized affidavit — enjoys under the Rules of Court, Rule 132, Section 19. The notary's fee in the Philippines is typically PHP 100 to PHP 500 depending on the notary's location and the document's complexity.
A Single Proprietorship Affidavit in the Philippines does not have a statutory validity period — its validity depends on the requirements of the institution requesting it. Philippine banks, government agencies, and procurement offices typically require an affidavit that is not more than three to six months old from the date of notarization, as older affidavits may not reflect the current status of the business. Since the affidavit attests to the current ownership of the business, any change in ownership, DTI registration status, or business structure requires a new affidavit. When renewing a DTI business name certificate — which is valid for five years under DTI Administrative Order No. 18-10 — the proprietor typically executes a fresh Single Proprietorship Affidavit as part of the renewal process. For PhilGEPS registration renewals, the procurement portal requires updated eligibility documents, including a current affidavit, within the prescribed renewal period.
A Single Proprietorship Affidavit (Philippines) does not legally require a lawyer in Philippines, and individuals and businesses may draft and execute the document independently. The Revised Corporation Code (RA 11232, 2019) does not mandate legal representation for the creation or signing of this type of document. However, seeking independent legal advice from a qualified Philippines lawyer is recommended for transactions involving substantial financial value, complex regulatory requirements, or cross-border elements where multiple legal jurisdictions may apply. A lawyer can verify that the document complies with all applicable statutory requirements, identify potential risks specific to the transaction, and confirm that the terms adequately protect the interests of all parties involved. The Supreme Court of the Philippines has jurisdiction over disputes arising from this type of document, and Securities and Exchange Commission (SEC Philippines) may impose additional compliance obligations depending on the nature of the underlying transaction. Professional legal review is particularly advisable where the document will be submitted to government agencies or used as evidence in legal proceedings.
