TL;DR:
External audits verify financial accuracy, ensure regulatory compliance, and boost credibility with lenders and investors.
The SEC and BIR apply separate thresholds — assets/liabilities and gross revenue respectively — and a business must satisfy both. Only the very smallest companies will be fully exempt.
Preparing for audits and maintaining strong internal controls remain essential regardless of exemption status.
Many business owners assume external audits are reserved for large corporations. While thresholds have recently been updated, exemptions still concern only the smallest companies — meaning most operating businesses will still need to undergo an external audit. With the April 15 deadline approaching for many businesses, understanding the external audit process is no longer optional. This guide breaks down what external audits are, who needs one this year, how the process works step by step, and what the 2026 reforms mean for your compliance strategy.

What is an external audit?
An external audit is an independent examination of a company’s financial statements, conducted by a licensed Certified Public Accountant (CPA) who has no affiliation with the business. The auditor’s job is to verify that your financial records accurately reflect the company’s actual financial position, following the Philippine Financial Reporting Standards (PFRS).
This is different from an internal audit, which is performed by someone within your organization. Internal audits focus on operational efficiency and internal controls. External audits focus on accuracy, transparency, and regulatory compliance. Think of it this way: an internal audit is a self-check, while an external audit is an independent verification.
Why does it matter for your business?
External audits serve several practical purposes beyond just checking a box:
-
They give lenders and investors confidence in your financial data
-
They reduce the risk of red flags during BIR tax audits
-
They surface errors in your books before regulators do
-
They strengthen your credibility when bidding for contracts or applying for loans
As noted by audit professionals, external audits boost trust and open doors for loans and contracts that would otherwise be out of reach for smaller businesses. This is especially relevant for foreign-owned enterprises in the Philippines, where demonstrating financial transparency is critical for regulatory standing.
For businesses navigating BIR filings and other obligations, pairing your audit readiness with solid tax compliance steps is the most efficient path forward.
Pro Tip: Even if your business is not legally required to have an external audit this year, having audited financials can significantly improve your chances of securing bank loans or attracting investors.
Who needs an external audit in the Philippines?
Understanding what an external audit is raises the next key question: does your business actually need one under the current rules?
The answer depends on your business type, size, and the 2026 threshold changes that have reshaped requirements for many companies.
Businesses that are generally required to have an external audit:
-
Stock corporations registered with the Securities and Exchange Commission (SEC)
-
Foreign-owned corporations and branch offices operating in the Philippines
-
Companies in regulated industries (banking, insurance, publicly listed firms)
-
Partnerships and corporations with total assets or revenues above the updated 2026 thresholds
-
Businesses applying for specific government contracts or licenses that require audited financials
The 2026 reforms introduced a significant change: more micro, small, and medium enterprises (MSMEs) are now exempt from mandatory external audits if they fall below the revised asset and revenue thresholds. According to updated audit requirements, this shift is designed to reduce compliance costs for smaller businesses and allow auditors to focus their capacity on larger entities.
What this means in practice:
| Business type | Audit required in 2026? |
|---|---|
| Micro enterprises | Generally exempt (see updated thresholds below) |
| Small enterprises | May be exempt (see updated thresholds below) |
| Medium enterprises | Required |
| Large corporations | Required |
The SEC and BIR thresholds are independent of each other.
The SEC looks at total assets or total liabilities (updated threshold: ₱3,000,000), while the BIR looks at gross annual sales or receipts (threshold: ₱3,000,000). A company must clear both tests to be fully exempt. In practice, this means a company with modest assets but active revenues — which describes most operating businesses — will still require an audited financial statement for BIR purposes even if it qualifies for the SEC exemption.
The cost savings for qualifying MSMEs are real. Audit fees in the Philippines can range from tens of thousands to hundreds of thousands of pesos depending on company size and complexity. Being exempt frees up budget for operations and growth.
However, exemption does not mean you can ignore your books. You still need accurate financial records for BIR filings, SEC submissions, and any future audit triggers. Staying current on 2026 regulatory trends will help you stay ahead of any additional changes that could affect your status.
Pro Tip: Check your total assets and gross revenues against the updated SEC and BIR thresholds before assuming you are exempt. The thresholds apply to specific reporting periods, and crossing them mid-year can affect your obligations for the following cycle.
What to do if you are below the thresholds:
If your company falls below both the SEC and BIR thresholds, you are not required to submit audited financial statements — but you are still required to file financial statements. For the SEC, you must submit unaudited financial statements accompanied by a sworn Statement of Management’s Responsibility (SMR), signed by your board chair, president or CEO, and treasurer or CFO. For the BIR, financial statements must still be attached to your Annual Income Tax Return, prepared in accordance with applicable standards.
Importantly, management assumes full legal responsibility for the accuracy and completeness of unaudited submissions. False or misleading statements carry penalties under both the Securities Regulation Code and the Revised Corporation Code. The absence of an external auditor does not reduce your legal exposure — it shifts the accountability entirely onto your officers.
Note: Prior to 2026, companies below the threshold only needed financial statements certified by the treasurer or CFO. The new rules under MC No. 4 require a full SMR signed by three officers, reflecting a higher accountability standard even for exempt companies.
The external audit process: Step by step
Once you know you need an audit, you will want to understand exactly how the process works in practice. Knowing what to expect reduces stress and helps you prepare the right documents in advance.
The typical external audit process follows these phases:
-
Engagement and planning. You hire an independent CPA firm and sign an engagement letter. The auditor reviews your business, identifies risk areas, and plans the scope of the audit.
-
Document request. The auditor sends a list of required documents, typically including financial statements, general ledgers, bank statements, invoices, contracts, and tax returns.
-
Fieldwork. This is the main phase. Auditors test transactions, verify balances, and examine supporting documents. They may conduct interviews with your accounting staff.
-
Audit testing. Auditors perform substantive testing (verifying specific transactions) and analytical procedures (comparing ratios and trends against industry benchmarks).
-
Draft report review. The auditor shares preliminary findings. This is your chance to clarify discrepancies or provide additional documentation.
-
Final audit report. The auditor issues a signed opinion, typically one of four types: unqualified (clean), qualified, adverse, or disclaimer of opinion.
-
Submission. You file the audited financial statements with the BIR (attached to your Annual Income Tax Return) and the SEC, generally within 120 days after your fiscal year-end.
Common documents auditors request:
-
Audited and unaudited trial balances
-
Bank reconciliation statements
-
Accounts receivable and payable schedules
-
Fixed asset register
-
Official receipts and sales invoices
-
Payroll records and government remittance proof (SSS, PhilHealth, Pag-IBIG)
-
BIR tax clearance and prior-year returns
Pitfalls to avoid:
-
Submitting incomplete or inconsistent records, which triggers extended fieldwork
-
Missing the document request deadline from your auditor, which delays the final report
-
Failing to reconcile bank statements before the audit begins
Solid compliance preparation before the audit starts saves you significant time and reduces the risk of a qualified opinion.
How recent reforms change external audits in 2026
The core change in 2026 centers on revised audit thresholds issued under SEC Memorandum Circular No. 4, Series of 2026 (effective January 20, 2026). The SEC raised the mandatory audit threshold from ₱600,000 to ₱3,000,000 in total assets or liabilities — a fivefold increase designed to reduce compliance costs for micro-enterprises. The BIR threshold, set under the TRAIN Law, remains at ₱3,000,000 in gross annual sales or receipts. Both thresholds apply to financial statements covering fiscal years ending on or after December 31, 2025.
Key features of the 2026 reforms:
-
Higher asset and revenue thresholds before mandatory audit applies
-
Clearer exemption criteria for micro and small enterprises
-
Increased focus of audit resources on medium and large corporations
-
Encouragement for exempted businesses to adopt stronger internal financial controls
-
No change to audit requirements for foreign-owned corporations and regulated industries
Experts offer a nuanced view. On one hand, the reforms provide real financial relief for small business owners. On the other, audit professionals warn that exempted businesses face a risk of reduced financial assurance, making strong internal controls and accurate bookkeeping even more critical.
The relief for MSMEs is welcome, but businesses that skip the audit process must compensate with stronger internal processes. The absence of an external check does not mean the absence of risk.
For businesses that are no longer required to be audited, this is not a green light to relax your financial discipline. Lenders, investors, and government agencies may still request audited financials. And if your revenue grows past the threshold mid-cycle, you could find yourself scrambling to prepare for an audit you did not plan for.
Keeping pace with Philippines 2026 reforms ensures you are not caught off guard by any further adjustments to these thresholds or submission timelines.
Our perspective: What most business owners overlook about external audits
Most guides stop at compliance. They tell you who needs an audit and when to file. That is useful, but it misses the bigger picture.
An external audit is not just a regulatory exercise. It is one of the most credible signals you can send to banks, investors, and partners. A clean audit opinion says: this business knows its numbers, and someone independent verified that. That kind of credibility is hard to build any other way.
Here is the part that often gets overlooked: even if you are now exempt under the 2026 reforms, your financial discipline should not change. Audit professionals emphasize that exempted businesses need stronger internal controls, not weaker ones. The audit was a forcing function for accuracy. Without it, that discipline has to come from within.
Our advice: adopt the audit mindset regardless of your exemption status. Keep your books clean, reconcile monthly, and maintain documentation as if an auditor could walk in tomorrow. This keeps you lender-ready and investor-ready at all times. Pair this with a clear compliance and tax strategy and you will be ahead of most businesses your size.

Frequently asked questions
What is the deadline for submitting external audit reports in the Philippines?
Audit reports are typically filed with the BIR and SEC within 120 days after your fiscal year-end, with the April 15 deadline applying to calendar-year filers submitting their Annual Income Tax Return. Specific deadlines may vary based on entity type and any updated regulatory guidance.
Are all MSMEs required to have an external audit in 2026?
Not automatically — but most will still need one. Full exemption requires falling below both the SEC threshold (₱3M in total assets or liabilities) and the BIR threshold (₱3M in gross annual sales or receipts). These are separate tests. Those below both thresholds must still file unaudited financial statements with the SEC accompanied by a sworn SMR, and attach financial statements to their Annual ITR with the BIR.
How does an external audit reduce tax audit risk?
A properly conducted external audit ensures your financial statements are accurate and well-documented, which means fewer red flags for BIR examiners and a lower likelihood of being selected for a tax audit.
What should I prepare for my first external audit?
You will need complete financial records, bank reconciliation statements, supporting documents for all income and expenses, payroll records, and proof of tax payments and government remittances. The earlier you organize these, the smoother the audit will go.
What happens if a company required to be audited does not comply?
Noncompliance can result in monetary fines, denial of SEC or business permit renewal, and potential tax investigations by the BIR. It is not a risk worth taking when the consequences directly affect your ability to operate legally.
