Facing a tax audit from the Bureau of Internal Revenue (BIR) can be intimidating.
However, knowing what to expect and preparing in advance can turn this challenge into an opportunity to improve compliance and financial management.
Understanding what a BIR Audit is
What is a BIR Audit?
A BIR audit is a formal review of a taxpayer's financial records and tax returns for a specific fiscal year, authorized by a Letter of Authority (LOA), to verify tax compliance and accuracy in reporting income, deductions, and tax liabilities.
The goal is to confirm that businesses have properly reported their income and paid the correct taxes.
Common Triggers for an Audit
Several factors may increase your chance of prompting a BIR audit, including:
Consistent Failure to Pay or Remit Taxes – Businesses that fail to pay taxes through the Electronic Bureau of Internal Revenue Forms (eBIRForms) or BIR’s Electronic Filing and Payment System (eFPS), or frequently amend tax returns to reflect lower dues, may be flagged.
Discrepancies in Tax Returns – Large inconsistencies between submitted financial records and reported tax figures can raise red flags.
Other Factors – Businesses with foreign shareholders, high and fluctuating revenues and profits would be more likely to be scrutinized.
What is an RDO?
The Revenue District Office (RDO) is the local BIR branch overseeing tax compliance and audits within a specific area.
While it handles the audit process, formal tax assessments are approved at the regional or national level.
The BIR Audit Process: Step-by-Step
1. Letter of Authority (LOA)
Definition: A Letter of Authority (LOA) is an official document issued by the BIR, signed by the Commissioner or authorized officials, granting permission to examine a taxpayer's books and records. The audit cannot proceed without a valid LOA.
Required Documents: Businesses must submit records like ledgers, sales invoices, tax returns, and purchase schedules.
2. Document Submission & Initial Examination
Organizing Your Records: Ensure all requested documents are complete and well-organized to facilitate a smoother audit.
Submission Deadline: Taxpayers typically have 10 days from receipt of the LOA to submit the required documents. If documents are not submitted within this period, the BIR may issue a first and second/final notice to present documents after receiving the LOA.
Non-submission can lead to an SDT (subpoena duces tecum), where BIR can ask the court to compel the taxpayer to comply and the liability shifts from civil to criminal.
3. Notice of Discrepancy (NOD) & Discussion
What It Means: If the BIR finds discrepancies, they issue a Notice of Discrepancy (NOD). The taxpayer has 30 days to discuss and submit supporting documents to refute the findings.
Response Options: Taxpayers have 5 days to present their explanation and supporting documents. If more time is needed, additional documents may be submitted within 30 days after the initial notice.
4. Preliminary Assessment & Final Notices
Preliminary Assessment Notice (PAN): A PAN is issued if discrepancies remain unresolved after the NOD stage. Taxpayers have 15 days to file a written reply, or the BIR may proceed with a Final Assessment Notice (FAN).
Formal Letter of Demand (FLD) & Final Assessment Notice (FAN): If the BIR finds discrepancies after the PAN response, they issue a Final Assessment Notice (FAN) with a Formal Letter of Demand (FLD). Taxpayers have 30 days to protest, and if a reinvestigation is requested, they have 60 days to submit supporting documents
Disputing or Settling: Upon receiving the FLD/FAN, taxpayers have 30 days to file a protest letter requesting reconsideration or reinvestigation. Failure to do so makes the assessment final.
5. Final Decision and Appeal
Final Decision on Disputed Assessment (FDDA): If the BIR rejects the protest, it issues a Final Decision on Disputed Assessment (FDDA). The taxpayer has 30 days to appeal to the Court of Tax Appeals (CTA). If the BIR fails to issue an FDDA within 180 days, the taxpayer can treat it as a deemed denial and file an appeal.
Appealing to the Court of Tax Appeals (CTA): Taxpayers can file an appeal with the CTA within 30 days of receiving the FDDA.
The CTA reviews the case and determines if the assessment should be modified or canceled.
Tips for a Smooth Audit Experience
Maintain a Professional and Courteous Approach – A cooperative attitude can lead to a more favorable outcome.
Keep a Record of All Communications – Always document exchanges with the BIR using signed transmittals for tracking.
Update Your BIR Officer Regularly – Keeping them informed about your audit progress shows transparency.
Meet All Deadlines – Late submissions can lead to penalties and delays.
Consult a Tax Professional – Expert guidance can help navigate the audit process and ensure compliance.
In short: To ensure a smooth audit, maintain organized records, verify the validity of the LOA, document all communications, meet deadlines, and consult a tax expert when necessary.
