For most taxpayers in the Philippines, the annual income tax return is not the only thing to watch. You also need to know when to submit the filed income tax return, Audited Financial Statements, and other attachments to the Bureau of Internal Revenue. As a general rule, calendar-year taxpayers file and pay their Annual Income Tax Return by April 15 of the following year, then submit applicable attachments through the BIR’s eAFS system within the period allowed by BIR issuances. For the 2025 taxable year filed in 2026, however, the BIR extended the deadline to May 15, 2026, with a limited further extension to May 25, 2026 only for taxpayers affected by eAFS system-related issues.

Quick Answer: What Is the Deadline?

The answer depends on which deadline you mean: the deadline to file the Annual Income Tax Return, the deadline to pay the tax, the deadline to submit BIR attachments through eAFS, or the separate deadline to submit Audited Financial Statements to the Securities and Exchange Commission.

Requirement	Usual deadline	Where submitted	Important note
Annual Income Tax Return for calendar-year taxpayers	April 15 of the following year	BIR eFPS, eBIRForms, authorized tax software provider, or manual filing only when allowed	This is also generally the deadline to pay the tax due.
BIR attachments, including filed ITR and AFS, if applicable	Usually within 15 days from the deadline of filing, or within 15 days from actual late filing	BIR eAFS facility	The eAFS confirmation receipt is the proof of submission.
2025 Annual ITR, payment, and required attachments filed in 2026	May 15, 2026	BIR electronic platforms and eAFS	The BIR clarified that the required attachments for 2025 returns were also due on May 15, 2026.
2025 AFS attachments affected by eAFS system issues	May 25, 2026	BIR eAFS or applicable contingency process	This did not extend the ITR filing deadline; it only applied to affected AFS/attachment submissions. (Bir Cdn)
SEC AFS for corporations	Based on SEC eFAST rules and SEC annual schedule	SEC eFAST	This is separate from BIR eAFS. The SEC may set a different date. (SEC eFAST)

The most common mistake is assuming that “filing the ITR” and “submitting the AFS” are the same act. They are related, but they are not the same deadline, not the same upload process, and not always handled by the same government system.

What Does “Submit Filed ITR and Audited Financial Statements” Mean?

In practice, this phrase usually refers to the BIR requirement to submit supporting attachments after filing the Annual Income Tax Return.

These attachments may include:

the filed Annual Income Tax Return;
proof of payment, if tax was paid;
Audited Financial Statements or unaudited financial statements, depending on the taxpayer;
Statement of Management’s Responsibility;
Certificate of Independent Certified Public Accountant, if applicable;
BIR Form 2307 for creditable withholding taxes;
BIR Form 2316 for compensation income, if applicable;
BIR Form 1709 for related-party transactions, if applicable; and
other supporting schedules and tax credit documents.

Under current BIR procedure, taxpayers who file electronically generally submit these attachments through the Electronic Audited Financial Statements system, commonly called eAFS. The BIR has also said that a physical “Received” stamp on the Annual Income Tax Return is not required where the taxpayer has the proper electronic proof of filing, such as the Filing Reference Number, Tax Return Receipt Confirmation, or eAFS confirmation receipt.

This matters because many taxpayers still think they need to line up at the Revenue District Office just to have documents stamped. In many cases, what the BIR now expects is proper electronic filing, electronic payment when applicable, and timely uploading of attachments.

Legal Basis for the Deadline

The deadline rules come mainly from the National Internal Revenue Code, as amended by later tax laws and implemented by BIR regulations and revenue memorandum circulars.

The Ease of Paying Taxes Act, Republic Act No. 11976, signed in 2024, modernized several taxpayer compliance rules. It recognized electronic and manual filing, payment through authorized channels, taxpayer classification by size, and the BIR’s move toward an integrated digital system for registration, filing, payment, and submission of supporting documents. (Lawphil)

For individual taxpayers, Section 51 of the Tax Code governs the filing of individual income tax returns. For corporations, the corporate annual return is generally filed as a final adjustment return after the close of the taxable year. For taxpayers required to keep books of accounts, Section 232 is especially important because it is the provision that requires certain taxpayers to have their books audited by an independent Certified Public Accountant when they exceed the statutory threshold. BIR issuances applying Section 232 refer to the rule that taxpayers whose gross annual sales, earnings, receipts, or output exceed ₱3,000,000 must have their books audited yearly by an independent CPA and attach the required financial statements to the income tax return. (Bir Cdn)

Who Needs to Submit Audited Financial Statements?

Not every person who files an income tax return needs Audited Financial Statements. The requirement usually applies to businesses and entities that meet the audit threshold or are required by another regulator to submit audited financial reports.

Common taxpayers who may need AFS

Taxpayer	Is AFS usually required?	Practical explanation
Domestic corporation	Usually yes	Corporations commonly need audited financial statements for both BIR and SEC compliance.
Partnership	Usually yes if engaged in business and above the threshold	Partnerships generally keep books and file business tax returns.
Sole proprietor or professional	Required if gross annual sales, receipts, earnings, or output exceed ₱3,000,000	Below the threshold, unaudited financial statements or simpler records may apply, depending on the taxpayer’s classification and BIR requirements.
Mixed-income earner	Depends	A salaried employee with a small registered business may have business filing obligations separate from employment income.
Pure compensation-income employee	Usually no	Employees qualified for substituted filing normally do not submit AFS.
Branch or representative office of a foreign corporation	Usually yes	SEC and BIR compliance normally applies if registered and doing business in the Philippines.

The practical rule is simple: once you are operating a registered business, especially through a corporation, partnership, branch, or professional practice, you should confirm whether your books need to be audited before the annual filing season starts. Waiting until April often creates bottlenecks because accountants, auditors, and bookkeepers are handling many clients at the same time.

The Usual BIR Timeline for Calendar-Year Taxpayers

For a taxpayer using the calendar year, the normal annual tax compliance flow looks like this:

Close the books as of December 31. Sales, expenses, withholding tax certificates, inventories, depreciation schedules, bank balances, and year-end adjustments must be finalized.
Prepare the financial statements. These usually include the Statement of Financial Position, Statement of Comprehensive Income, Statement of Changes in Equity, Statement of Cash Flows, and Notes to Financial Statements.
Complete the audit, if required. If the taxpayer is required to submit Audited Financial Statements, the independent CPA performs audit procedures and signs the independent auditor’s report.
Prepare and file the Annual Income Tax Return. Common forms include BIR Form 1700 for pure compensation income, BIR Form 1701 or 1701A for individuals with business or professional income, and BIR Form 1702-RT, 1702-EX, or 1702-MX for corporations. BIR RMC No. 20-2026 listed these forms as available in the eFPS system for the 2025 filing season.
Pay the income tax due, if any. Payment may be made through authorized electronic channels or authorized agent banks, depending on the taxpayer and the BIR rules for that filing season. The BIR has recognized payment options such as LandBank Link.BizPortal, UnionBank, DBP PayTax, Maya, and other authorized channels in its filing-season guidance.
Submit the applicable attachments through eAFS. After filing the return, the taxpayer uploads the required attachments to the eAFS system within the BIR-prescribed period.
Save the proof of filing and submission. Keep the Filing Reference Number, Tax Return Receipt Confirmation, payment confirmation, and eAFS Transaction Reference Number or confirmation email. These are important if the taxpayer is later asked to prove timely compliance.

The Special 2025 Annual ITR Deadline Filed in 2026

For the taxable year ending December 31, 2025, the normal April 15, 2026 deadline was extended.

The BIR issued RMC No. 30-2026 extending the deadline for filing the 2025 Annual Income Tax Return, payment of the corresponding tax, and submission of required attachments to May 15, 2026. The BIR later clarified in RMC No. 39-2026 that the deadline for submitting the required attachments to the 2025 Annual Income Tax Return was also May 15, 2026, even if the taxpayer filed the return on or before April 15, on April 16, or on May 15.

This clarification is important because taxpayers might otherwise assume that the 15-day attachment period should be counted from May 15, giving them until May 30. For the 2025 annual return cycle, that was not the BIR’s clarification. The applicable deadline for the required attachments was May 15, 2026, except for the limited eAFS issue covered by RMC No. 46-2026.

RMC No. 46-2026 then gave affected taxpayers until May 25, 2026 to submit AFS and other attachments without penalties if they were unable to successfully submit through eAFS on or before May 15, 2026 due to system-related issues, or if they submitted through the contingency email process but had not received acknowledgement. This was not a blanket extension of the income tax return filing deadline. (Bir Cdn)

How to Submit Filed ITR and AFS Through BIR eAFS

The usual process is straightforward, but mistakes in naming files, uploading the wrong documents, or missing the confirmation receipt can create problems later.

Step-by-step guide

File the Annual Income Tax Return first. Use the platform required for your taxpayer type: eFPS, eBIRForms, authorized tax software provider, or manual filing only if permitted by BIR rules.
Pay the tax due, if any. Save the payment confirmation, bank validation, or proof of electronic payment.
Prepare PDF copies of the attachments. Make sure the documents are complete, signed where required, and consistent with the figures in the filed return.
Upload the documents through eAFS. The BIR requires applicable attachments to be submitted electronically through eAFS, except when there is an official BIR advisory or recognized system unavailability allowing manual submission.
Download or save the confirmation. The eAFS Transaction Reference Number or confirmation receipt is your proof that the attachments were submitted.
Keep a compliance folder. Save the filed return, payment proof, AFS, eAFS confirmation, email acknowledgements, and screenshots in one folder. For companies, keep this together with the SEC eFAST submission proof.

Documents Commonly Submitted With the Annual ITR

The exact attachments depend on the taxpayer. The BIR expressly states that only applicable attachments need to be submitted.

Document	When commonly needed
Filed Annual Income Tax Return	For taxpayers submitting the annual return and attachments
Proof of payment	If income tax was paid
Audited Financial Statements	Required when the taxpayer meets the audit requirement or is otherwise required to submit AFS
Unaudited financial statements	For taxpayers required to submit financial statements but not required to submit audited ones
Notes to Financial Statements	Usually part of complete AFS
Statement of Management’s Responsibility	Commonly required with AFS
Certificate of Independent CPA accredited by BIR	For taxpayers with audited financial statements
BIR Form 2307	To claim creditable withholding taxes
BIR Form 2316	For compensation income or mixed-income cases where applicable
BIR Form 1709	For taxpayers with related-party transactions
SAWT validation or acknowledgement	When claiming withholding tax credits supported by Summary Alphalist of Withholding Taxes
Proof of foreign tax credits or prior-year excess credits	When claiming these tax credits

A common practical issue is that the income tax return may be ready before the audit is complete. If the taxpayer is required to submit AFS, the return, the AFS, and the tax credit documents should still be reconciled. Differences between the return and the financial statements can trigger BIR questions later.

BIR eAFS Deadline vs SEC eFAST Deadline

For corporations, there are usually two separate annual submissions:

BIR eAFS submission — for the filed tax return, AFS, and tax attachments; and
SEC eFAST submission — for the corporation’s annual financial statements and other SEC reportorial requirements.

Do not assume that submitting to one agency automatically satisfies the other. The BIR and SEC use different systems, different rules, and sometimes different deadlines.

The SEC’s eFAST system is used for electronic submission of financial statements and other corporate reports. SEC guidance states that financial statements are submitted through eFAST and that submissions may be reverted if the uploaded report has issues, meaning the report may be treated as not filed until properly corrected and accepted. (SEC eFAST)

For the 2025 AFS filing season, the SEC also adjusted deadlines following the BIR extension. Publicly reported guidance for 2026 showed that ordinary domestic and foreign corporations with fiscal year ending December 31, 2025 had an extended SEC AFS deadline of June 15, 2026, while certain regulated entities had different dates. (Grant Thornton Philippines)

The practical sequence for corporations is usually:

finalize and audit the AFS;
file the Annual ITR with the BIR;
submit BIR attachments through eAFS;
obtain the BIR eAFS confirmation;
submit the AFS to the SEC through eFAST, attaching the required proof of BIR submission when required.

Common Scenarios and What They Mean

You filed the Annual ITR on time but uploaded the AFS late

This can still create a compliance problem. Filing the return and submitting attachments are separate requirements. A taxpayer may have timely filed and paid the tax but still be exposed to penalties for late submission of required attachments.

You filed late

Under the usual BIR rule stated in filing-season guidance, if a taxpayer files late, the applicable attachments are submitted within 15 days from the actual late filing. But late filing of the return itself can still result in surcharge, interest, and compromise penalties.

You have no tax payable

A “no payment” return is still a return. If you are required to file, you must file even if the tax due is zero. If you are required to submit attachments, the lack of tax payable does not automatically remove the attachment requirement.

Your accountant filed the return but did not send you proof

Ask for copies of:

the filed BIR form;
Filing Reference Number or Tax Return Receipt Confirmation;
payment confirmation, if any;
AFS and audit report;
eAFS confirmation receipt; and
SEC eFAST proof, if the taxpayer is a corporation.

In real BIR examinations, the taxpayer—not the bookkeeper—is the one expected to produce proof of filing and submission.

The eAFS system was down

Save screenshots, BIR advisories, email acknowledgements, and proof of attempted submission. The BIR has recognized system-related problems in specific issuances, such as RMC No. 46-2026 for the 2025 AFS submission period, but taxpayers should not assume that every technical issue automatically excuses late filing. (Bir Cdn)

You are abroad and managing a Philippine company remotely

Foreign-based officers and Filipino owners abroad should plan earlier. Documents may need wet signatures, notarization, board approvals, auditor coordination, or apostille if signed abroad for certain corporate purposes. For BIR eAFS, scanned electronic submissions are common, but the underlying documents should still be properly executed and available in company records.

Foreigners, OFWs, and Philippine Tax Filing

Foreigners and Filipinos abroad often ask whether they need to file Philippine income tax returns and submit AFS.

The key question is whether the taxpayer is earning taxable income connected to the Philippines.

Under Philippine tax rules, resident citizens are generally taxed on worldwide income, while nonresident citizens, overseas Filipino workers, aliens, and foreign corporations are generally taxed only on income from Philippine sources, depending on their classification. (ICNL)

Republic Act No. 11976 also reflects the rule that an overseas Filipino worker or nonresident citizen earning income solely from abroad is generally not required to file a Philippine income tax return for that foreign income. (Lawphil)

But this does not mean that every Filipino abroad or foreigner can ignore Philippine tax filing. Examples where Philippine filing may still matter include:

a Filipino abroad who owns a registered rental business in the Philippines;
a foreigner who operates a Philippine sole proprietorship or professional practice;
a nonresident alien engaged in trade or business in the Philippines;
a foreign corporation with a Philippine branch;
a foreign shareholder dealing with dividends, capital gains, or other Philippine-source income; or
a Philippine corporation owned or managed by foreigners.

If there is a registered Philippine business, the BIR and SEC compliance obligations usually follow the registration, not the physical location of the owner.

Penalties for Missing the Deadline

Late filing, late payment, and late submission of attachments can result in tax penalties. These may include:

surcharge;
interest;
compromise penalties;
denial or delay of tax credit claims if supporting documents are incomplete;
problems during BIR audit or tax clearance applications; and
SEC penalties for corporations that fail to file reportorial requirements on time.

The Ease of Paying Taxes Act introduced reduced penalties for micro and small taxpayers in certain situations, including reduced civil penalties, lower interest, and reduced compromise penalties, but this does not remove the obligation to file and submit required documents on time. (Lawphil)

The safest practical approach is to treat the ITR deadline, the eAFS deadline, and the SEC eFAST deadline as separate compliance dates and track each one.

Practical Filing Checklist

Use this checklist before the annual filing season:

Item	Why it matters
Confirm taxpayer classification	Micro, small, medium, and large taxpayers may have different compliance rules under the Ease of Paying Taxes framework.
Confirm correct BIR form	Filing the wrong form can cause delays or amendments.
Reconcile books, tax returns, and withholding certificates	Differences can affect tax credits and audit risk.
Confirm whether AFS must be audited	The ₱3,000,000 threshold and corporate requirements are common triggers.
File the Annual ITR on time	This is the main income tax filing obligation.
Pay the tax due on time	Filing without payment may still lead to penalties.
Upload attachments through eAFS	Filing the return alone may not complete the annual compliance package.
Save all confirmations	Electronic proof is critical if questioned later.
Check SEC eFAST deadline if a corporation	SEC filing is separate from BIR filing.

Frequently Asked Questions

When is the deadline to submit filed ITR and AFS to the BIR?

Under the usual BIR filing-season rule, applicable attachments are submitted through eAFS within 15 days from the deadline of filing the Annual Income Tax Return, or within 15 days from actual filing if the return was filed late. For the 2025 Annual ITR filed in 2026, the BIR set May 15, 2026 as the extended deadline for filing, payment, and required attachments.

Is the AFS deadline always April 15?

No. April 15 is usually the calendar-year Annual ITR filing and payment deadline. The AFS and other attachments usually have their own submission period through eAFS. For corporations, the SEC AFS deadline is also separate and may fall on a different date.

If I filed my ITR on April 15, can I submit AFS later?

Usually, yes, if the BIR allows a separate attachment submission period. But you must follow the specific BIR deadline for that taxable year. For the 2025 return cycle, the BIR clarified that required attachments were due by May 15, 2026, even for taxpayers who filed earlier. (Bir Cdn)

Do I still need to submit AFS if my business had no income?

Possibly. A registered corporation or business may still have filing obligations even if it had no income or no tax payable. The requirement depends on the taxpayer type, registration, gross receipts, and applicable BIR or SEC rules.

Who is required to submit Audited Financial Statements in the Philippines?

Taxpayers required to keep books whose gross annual sales, earnings, receipts, or output exceed ₱3,000,000 are generally required to have their books audited by an independent CPA and attach the required financial statements to the income tax return. Corporations also commonly have SEC AFS obligations. (Bir Cdn)

Is eAFS the same as eFAST?

No. eAFS is the BIR system for submitting tax return attachments, including AFS. eFAST is the SEC system for submitting corporate reports such as financial statements. A corporation may need to use both.

What proof should I keep after submitting through eAFS?

Keep the eAFS Transaction Reference Number or confirmation receipt, the filed Annual ITR, proof of payment, AFS, tax credit certificates, and email confirmations. BIR guidance recognizes the eAFS confirmation as proof of submission.

What happens if eAFS rejects or fails to process my upload?

Correct the issue immediately and keep proof of the failed attempt. If the BIR issues a specific advisory or circular allowing contingency submission or granting relief, follow that issuance closely. For the 2025 AFS submission period, the BIR allowed a limited extension until May 25, 2026 for taxpayers affected by eAFS system-related issues. (Bir Cdn)

Do OFWs need to file Philippine income tax returns and AFS?

An OFW or nonresident citizen earning income solely from abroad is generally not required to file a Philippine income tax return for that foreign income. But if the OFW has Philippine business income, rental income, professional income, or owns a Philippine corporation, separate Philippine tax and reportorial obligations may apply. (Lawphil)

Key Takeaways

The usual calendar-year Annual Income Tax Return deadline is April 15 of the following year, but BIR extensions may change this for a specific taxable year.
Filing the ITR, paying the tax, submitting BIR attachments through eAFS, and submitting AFS to the SEC are separate compliance steps.
For the 2025 Annual ITR filed in 2026, the BIR extended the filing, payment, and required attachment deadline to May 15, 2026.
The May 25, 2026 extension applied only to affected taxpayers with eAFS system-related issues and did not extend the Annual ITR filing deadline.
Taxpayers with gross annual sales, receipts, earnings, or output exceeding ₱3,000,000 generally need Audited Financial Statements prepared by an independent CPA.
The eAFS confirmation receipt, Filing Reference Number, payment proof, and SEC eFAST confirmation should be saved permanently with the taxpayer’s annual compliance records.
Corporations should track both the BIR eAFS deadline and the separate SEC eFAST deadline.
