Yes. A One Person Corporation (OPC) in the Philippines generally needs to file financial statements with the Securities and Exchange Commission (SEC) and an Annual Income Tax Return (AITR or ITR) with the Bureau of Internal Revenue (BIR). The common mistake is thinking that because an OPC has only one owner, it is treated like a freelancer or sole proprietor. It is not. An OPC is still a corporation, and once it is registered, it carries continuing SEC and BIR compliance duties even if the business is small, newly registered, or temporarily inactive.

This article explains what an OPC must file, when financial statements need to be audited, how the ITR fits into the process, what documents are commonly required, and the practical problems Filipino and foreign single-owner businesses often face.

What Is an OPC in the Philippines?

A One Person Corporation is a corporation with a single stockholder. It was introduced under Republic Act No. 11232, or the Revised Corporation Code of the Philippines. Under Section 116, only a natural person, trust, or estate may form an OPC, subject to certain exclusions such as banks, insurance companies, public and publicly listed companies, and licensed professionals incorporating only to practice their profession, unless a special law allows it. (Supreme Court E-Library)

An OPC is different from a sole proprietorship in three important ways:

Issue	Sole Proprietorship	One Person Corporation
Legal personality	Same person as the owner	Separate juridical person
Registration agency	DTI for business name, plus BIR/LGU	SEC, plus BIR/LGU
Annual SEC filings	None	Required
BIR ITR	Individual business ITR	Corporate ITR
Liability	Generally personal	Limited liability, subject to proof of proper separation and adequate financing

The “limited liability” feature of an OPC is not automatic protection for every situation. Section 130 of the Revised Corporation Code says the single stockholder claiming limited liability has the burden of showing that the corporation was adequately financed and that the OPC’s property is independent from the stockholder’s personal property. If the owner cannot prove that separation, the owner may become jointly and severally liable for OPC debts. (Supreme Court E-Library)

That is why financial statements are not just a formality. They help prove that the OPC exists and operates separately from the individual owner.

Do OPCs Need to File Financial Statements with the SEC?

Yes. An OPC must submit annual financial statements to the SEC.

Section 129 of the Revised Corporation Code specifically requires an OPC to submit:

Annual financial statements, audited by an independent Certified Public Accountant (CPA), subject to the applicable audit threshold;
A report by the president explaining any qualification, reservation, adverse remark, or disclaimer made by the auditor;
A disclosure of all self-dealings and related-party transactions between the OPC and the single stockholder; and
Other reports the SEC may require. (Supreme Court E-Library)

Section 177 also requires every domestic or foreign corporation doing business in the Philippines to submit annual financial statements and a General Information Sheet (GIS) within the period prescribed by the SEC. The SEC may place a corporation under delinquent status if it fails to submit reportorial requirements three times, whether consecutively or intermittently, within five years. (Supreme Court E-Library)

Are the financial statements always audited?

Not always.

The old statutory text of the Revised Corporation Code refers to the ₱600,000 asset-or-liability threshold. However, the SEC’s 2026 adjustment to the audit threshold under Revised SRC Rule 68 increased the threshold to more than ₱3,000,000 in total assets or total liabilities for corporations covered by the rule, with the revised threshold applying to financial statements covering fiscal years ending on or after December 31, 2025. Corporations at or below the threshold may generally file unaudited financial statements with a sworn Statement of Management’s Responsibility, unless they fall under a category that still requires an audit, such as entities vested with public interest or specially regulated entities. (Grant Thornton Philippines)

For practical purposes:

OPC situation	SEC financial statement requirement
Total assets or total liabilities exceed the applicable SEC audit threshold	Audited financial statements are generally required
Assets and liabilities are within the micro threshold	Unaudited FS with sworn responsibility statement may be allowed, unless another rule requires audit
OPC is regulated, public-interest, or under a special license	Audit may still be required regardless of size
OPC had no operations	Filing is still normally required unless the corporation has been properly closed or dissolved

The safest working rule is simple: an OPC must prepare and file annual financial statements every year. The question is whether those statements must be audited.

Do OPCs Need to File an Annual ITR with the BIR?

Yes. An OPC must file a corporate Annual Income Tax Return with the BIR.

An OPC is a corporation for tax purposes. It does not use the personal business ITR forms used by sole proprietors or freelancers. Depending on its tax classification, it normally uses one of the corporate income tax return forms, such as:

BIR form	Common use
BIR Form 1702-RT	Corporation subject only to the regular corporate income tax rate
BIR Form 1702-MX	Corporation with mixed income tax rates or special tax regimes
BIR Form 1702-EX	Corporation claiming tax exemption

BIR Revenue Memorandum Circular (RMC) No. 20-2026 lists corporate AITR forms available through the electronic filing platforms, including BIR Forms 1702-RT, 1702-EX, and 1702-MX. It also reiterates that AITRs are filed through BIR electronic filing platforms such as eFPS and the Offline eBIRForms Package.

What corporate income tax rate applies to an OPC?

A domestic OPC is generally subject to corporate income tax. Under the Tax Code as amended by CREATE and CREATE MORE, the regular corporate income tax is generally 25%, but a 20% rate applies to domestic corporations with net taxable income not exceeding ₱5,000,000 and total assets not exceeding ₱100,000,000, excluding the land where the office, plant, or equipment is situated. Registered business enterprises under the enhanced deductions regime may also be subject to a 20% rate on taxable income from registered projects or activities. (Lawphil)

The ITR is still filed even if the tax due is zero. Filing and paying are different obligations. A company may have no income tax payable because of losses, excess credits, or no operations, but it may still need to file the required return and attachments.

SEC Financial Statements vs. BIR ITR: What Is the Difference?

Many owners confuse the SEC financial statements and the BIR ITR because they are prepared around the same time and use the same accounting records. They are related, but they are not the same.

Filing	Filed with	Purpose	Typical deadline
Financial Statements or AFS	SEC	Corporate reportorial compliance	Based on SEC annual filing rules; non-calendar fiscal years are generally within 120 calendar days from fiscal year-end
Annual ITR	BIR	Income tax declaration and payment	Generally 15th day of the 4th month after taxable year-end
BIR eAFS attachments	BIR	Submission of FS, SMR, certificates, proof of filing/payment, and supporting attachments	Usually within the BIR-prescribed period after ITR filing
GIS and other SEC reports	SEC	Updated corporate information and ownership/officer details	Based on SEC-prescribed periods

For the 2026 filing season covering calendar year 2025, BIR RMC No. 30-2026 extended the deadline for filing 2025 Annual Income Tax Returns, paying corresponding taxes, and submitting required attachments from April 15, 2026 to May 15, 2026. (Bir Cdn) The SEC also extended the 2025 AFS filing deadline for corporations with December 31, 2025 year-end from May 29, 2026 to June 15, 2026, following the BIR extension. (Grant Thornton Philippines)

For future years, always check the latest BIR and SEC circulars because annual filing calendars may change.

Step-by-Step Guide: How an OPC Usually Files FS and ITR

1. Check the OPC’s taxable year or fiscal year

Start with the Articles of Incorporation. Section 129 of the Revised Corporation Code says the fiscal year of an OPC is the one stated in its Articles of Incorporation; if none is stated, the calendar year applies. (Supreme Court E-Library)

Most small OPCs use the calendar year ending December 31. If your OPC uses a fiscal year, the deadlines move according to that fiscal year.

2. Close and reconcile the books

Before an accountant can prepare reliable financial statements, the OPC should reconcile:

Sales invoices and official receipts or invoices issued;
Purchases and expense receipts;
Bank statements;
Payroll records;
BIR Form 2307 certificates for creditable withholding tax;
Loans, advances, and payments between the OPC and the single stockholder;
Fixed assets, inventory, receivables, and payables;
VAT, percentage tax, expanded withholding tax, and compensation withholding tax filings, if applicable.

This step is where many OPCs run into problems. If the owner used one personal bank account for both personal and company transactions, the accountant may need more time to classify deposits, withdrawals, reimbursements, and owner advances.

3. Determine whether the FS must be audited

Ask two questions:

Does the OPC exceed the applicable SEC audit threshold?
Is the OPC in a category that requires audit regardless of size?

If an audit is required, the financial statements must be examined by an independent CPA. If not, the OPC may still need properly prepared unaudited financial statements, notes, and a sworn management responsibility statement.

4. Prepare the financial statements and supporting SEC documents

A basic annual FS package usually includes:

Statement of Financial Position;
Statement of Comprehensive Income or Income Statement;
Statement of Changes in Equity;
Statement of Cash Flows, when applicable;
Notes to Financial Statements;
Statement of Management’s Responsibility;
Independent Auditor’s Report, if audited;
President’s explanation of any auditor qualification or adverse remark, if applicable;
Related-party or self-dealing disclosure involving the single stockholder.

For OPCs, related-party disclosure is especially important because transactions between the owner and the corporation are common: cash advances, owner-funded expenses, loans, rent of owner property, use of vehicles, reimbursements, and management fees.

5. File the Annual ITR and pay any tax due

The OPC files the correct corporate AITR through the applicable BIR platform. RMC No. 20-2026 states that taxpayers mandated to use eFPS must file electronically and pay through enrolled eFPS-authorized agent banks, while non-eFPS taxpayers use the Offline eBIRForms Package for electronic filing. Manual filing is allowed only in limited situations such as BIR-advised system unavailability, justifiable reasons determined by the Commissioner or authorized representative, or unavailability of the return in the electronic platforms.

Payment may be made through eFPS, BIR ePayment gateways, or authorized payment channels. RMC No. 20-2026 identifies electronic payment options such as Land Bank Link.BizPortal, UnionBank online facilities, DBP PayTax Online, MyEG, and Maya, with certain over-the-counter options depending on the situation.

6. Submit BIR attachments through eAFS

After filing the AITR, the OPC submits applicable attachments through the BIR eAFS system. RMC No. 20-2026 lists common attachments such as proof of eFiling, proof of payment, certificate of the independent CPA duly accredited by the BIR, audited or unaudited financial statements, notes to FS, Statement of Management Responsibilities, BIR Form 2307, BIR Form 2304, BIR Form 2316, SAWT acknowledgment or validation report, and other applicable proofs of credits or related-party forms.

The same circular provides that applicable attachments are generally submitted through eAFS within fifteen days from the deadline of filing the return, or within fifteen days from filing in case of late filing.

7. File the FS or AFS with the SEC through eFAST

SEC filings are now made electronically through eFAST. For the 2026 filing season, SEC Memorandum Circular No. 9, Series of 2026 required AFS and GIS filings through eFAST, with AFS filing deadlines based on the corporation’s fiscal year and special rules for regulated entities. (Grant Thornton Philippines)

In practice, the SEC-uploaded FS should already show BIR receipt or eAFS confirmation, depending on the applicable SEC and BIR rules for that filing year.

8. Keep all confirmations and corporate records

Do not stop at uploading. Save copies of:

Filed AITR;
Filing Reference Number or Tax Return Receipt Confirmation;
Proof of payment;
eAFS Transaction Reference Number or confirmation receipt;
SEC eFAST QR code or confirmation;
Final signed FS or AFS;
CPA certificate, if applicable;
Corporate resolutions and minutes book entries;
Related-party disclosure;
Books of accounts and source documents.

For an OPC, these records are especially useful if the SEC, BIR, bank, investor, buyer, or court later asks whether the corporation was truly separate from the owner.

Required Documents for OPC Annual FS and ITR Filing

Requirement	Usually needed for	Practical notes
SEC Certificate of Incorporation	Accountant, auditor, bank, SEC filing	Confirms the OPC’s legal existence
Articles of Incorporation	SEC/BIR deadline review	Shows fiscal year, purpose, nominee details
BIR Certificate of Registration	Tax filing	Shows registered tax types and RDO
Books of accounts	FS and ITR preparation	Must match returns and source documents
Sales invoices and expense documents	Income and deduction support	Missing receipts can cause tax exposure
Bank statements	Reconciliation	Very important for single-owner companies
BIR Form 2307	Tax credits	Must match claimed creditable withholding tax
Payroll and withholding records	Expense and tax compliance	Needed if the OPC has employees
Audited or unaudited FS	SEC and BIR attachments	Audit depends on threshold and classification
Statement of Management’s Responsibility	SEC/BIR attachment	Signed by responsible corporate officers
CPA certificate	BIR attachment if audited	CPA must be properly accredited where required
Related-party disclosure	OPC SEC compliance	Important for owner-company transactions
eAFS and eFAST confirmations	Proof of filing	Keep digital and printed copies

Common Mistakes OPC Owners Make

Thinking “small business” means “no SEC filing”

An OPC may be small, but it is still a corporation. SEC registration gives it corporate personality, and that comes with continuing reportorial obligations.

Filing the ITR but forgetting SEC financial statements

The BIR and SEC are different agencies. Filing the Annual ITR does not automatically complete SEC compliance. The same financial statements may support both filings, but they must be submitted through the proper channels.

Filing with the SEC but forgetting BIR eAFS attachments

The BIR may require attachments after the AITR filing. RMC No. 20-2026 makes clear that applicable attachments are submitted electronically through eAFS, and the eAFS-generated reference or confirmation receipt serves as proof of submission.

Mixing personal and corporate money

This is one of the most dangerous mistakes for OPCs. If the owner freely mixes personal funds and OPC funds, it becomes harder to prove that the corporation has property separate from the single stockholder. That weakens the liability protection under Section 130 of the Revised Corporation Code. (Supreme Court E-Library)

Ignoring a “no operation” year

If the OPC has not been dissolved or its BIR registration has not been properly closed, assume annual filings may still be required. A dormant corporation can still accumulate SEC and BIR compliance problems.

Asking the CPA too close to the deadline

Audited financial statements take time. The CPA may need bank confirmations, schedules, invoices, contracts, inventory lists, tax returns, and explanations for unusual transactions. Starting only a few days before the deadline often leads to incomplete schedules, wrong tax credits, rushed notes, and late filings.

Not checking foreign ownership restrictions

A foreigner may be the single stockholder of an OPC if the business activity is not restricted and all applicable laws are followed. However, foreign ownership rules still apply. The current Foreign Investment Negative List identifies activities reserved for Philippine nationals or subject to foreign equity limits. Executive Order No. 113, s. 2026 promulgated the Thirteenth Regular Foreign Investment Negative List to reflect current restrictions and liberalizations. (Supreme Court E-Library)

Foreign OPC owners should also watch paid-in capital rules, nationality-sensitive industries, land ownership restrictions, and licensing requirements. The filing duties for FS and ITR remain the same, but the business may have additional compliance requirements depending on the activity.

What Happens If an OPC Does Not File?

Non-filing can create problems on several levels.

For the SEC, repeated failure to submit reportorial requirements can lead to delinquent status. Under the Revised Corporation Code, failure to submit required reports three times within five years may cause the SEC to place the corporation under delinquent status. (Supreme Court E-Library)

For the BIR, late or non-filing can result in penalties, interest, compromise penalties, and possible enforcement action. The BIR’s penalty guidance identifies failure to file returns, supply correct information, pay tax, withhold, or remit tax as a violation under Section 255 of the National Internal Revenue Code. (Bureau of Internal Revenue)

In real life, non-compliance may also block:

Bank account opening or loan applications;
Visa or investor documentation for foreigners;
Business permit renewals;
Government bidding or supplier accreditation;
Sale of the company or onboarding of investors;
SEC amendments, conversions, or dissolution;
BIR tax clearance or closure.

Practical Filing Timeline for a Calendar-Year OPC

For an OPC using the calendar year ending December 31, a practical annual workflow looks like this:

Period	What to do
January	Close books, collect bank statements, request BIR Form 2307 from clients
February	Reconcile taxes, sales, expenses, payroll, and related-party transactions
March	Finalize draft FS and determine whether audit is required
March to April	Complete audit or unaudited FS package, prepare Annual ITR
April 15, unless extended	File corporate Annual ITR and pay tax due
After ITR filing	Submit applicable BIR attachments through eAFS
SEC filing period	Submit FS or AFS through eFAST based on SEC schedule
After filing	Save all confirmations, update records, prepare for GIS or other SEC filings

Some years have special deadline extensions, as happened in 2026 for 2025 AITRs and related attachments. Treat those as year-specific relief, not a permanent rule.

Frequently Asked Questions

Does an OPC need audited financial statements every year?

Not always. An OPC must prepare and file annual financial statements, but audit depends on the applicable SEC threshold and the OPC’s classification. As of the 2026 SEC threshold adjustment, corporations at or below ₱3,000,000 in total assets or total liabilities may generally be allowed to file unaudited financial statements with a sworn responsibility statement, unless a special rule requires audit.

Does an OPC need to file an ITR even with no income?

Yes, if it remains BIR-registered and has not been properly closed. The ITR may show no tax payable, but the filing obligation normally remains.

What ITR form does an OPC use?

Most ordinary domestic OPCs subject only to the regular corporate income tax use BIR Form 1702-RT. OPCs with mixed tax regimes may use 1702-MX, while exempt corporations use 1702-EX, if applicable.

Is an OPC taxed like a sole proprietor?

No. An OPC is taxed as a corporation. A sole proprietor reports business income in an individual income tax return, while an OPC files a corporate income tax return.

Can the single stockholder sign the financial statements?

The required signatories depend on the filing, the SEC/BIR form, and whether the FS is audited or unaudited. For OPCs, the single stockholder is the sole director and president, but the OPC also has a treasurer and corporate secretary. The single stockholder may not be the corporate secretary. (Supreme Court E-Library)

What if my OPC did not operate after registration?

You should still address SEC and BIR filings unless the OPC has been properly dissolved and its BIR registration closed. Non-operation is not the same as closure.

Are BIR financial statements and SEC financial statements the same?

They usually come from the same accounting records, but they are submitted for different purposes. BIR uses them to support the ITR and tax attachments. SEC uses them for corporate reportorial compliance.

Do foreign-owned OPCs have different FS and ITR filing rules?

The annual filing duties are generally the same. The difference is that foreign-owned OPCs must also check foreign equity restrictions, paid-in capital rules, nationality limits, licensing requirements, and other industry-specific rules.

What is the biggest risk of not filing?

The biggest practical risk is accumulated non-compliance. One missed filing may be manageable, but repeated SEC and BIR failures can lead to penalties, delinquent status, difficulty closing or amending the corporation, and problems proving limited liability.

Key Takeaways

An OPC is a corporation, even if it has only one stockholder.
An OPC generally must file annual financial statements with the SEC and a corporate Annual ITR with the BIR.
The main question is not whether financial statements are needed, but whether they must be audited.
The corporate ITR is separate from SEC filing; both must be handled.
BIR attachments are commonly submitted through eAFS, while SEC financial statements are submitted through eFAST.
No operations or no income does not automatically remove filing duties.
Mixing personal and OPC funds can weaken limited liability protection.
Foreign single stockholders must comply with the same tax and SEC filings, plus applicable foreign ownership restrictions.
Keep all filing confirmations, receipts, financial statements, and corporate records because they prove both compliance and corporate separateness.
