VAT Compliance Philippines: Common Errors That Trigger BIR Audits
VAT compliance is one of the most closely audited areas in Philippine tax enforcement — and one of the most frequently mismanaged. Most businesses don’t discover their VAT exposure
One missed filing. One outdated receipt. That’s all it takes to trigger a costly audit. Let UNA’s Tax Health Check uncover hidden risks before the BIR does.
If you said YES to any of these, this Tax Health Check is for you.
Many businesses get into tax trouble not because of fraud or bad intent, but because of small mistakes like late filings, missing documents, or outdated processes. A Tax Health Check is like a routine check-up for your business taxes. It’s a professional review that identifies potential compliance risks, highlights red flags based on BIR standards, and ensures your business is audit-ready before any issues arise.
More importantly, tax Health Check can also uncover tax-saving opportunities and guide you in improving your processes for smoother, stress-free compliance in the future.
Your result will show how aligned your tax documentation and reporting practices are with current compliance standards—and what level of risk your business may be facing.

A Tax Health Check is a diagnostic review of your company’s tax filings, supporting documents, and compliance practices to identify risks, gaps, or missed opportunities—before they impact your operations.
It’s ideal for startups, growing businesses, or companies that have experienced rapid changes, complex transactions, or inconsistent filing practices. It’s also useful for businesses planning for expansion, restructuring, or seeking peace of mind.
We review tax return filings, schedules and attachments, reconciliation practices, VAT claims, withholding taxes, supporting documentation, and internal processes related to tax compliance.
