What is a BIR Notice of Discrepancy?
A BIR Notice of Discrepancy (NOD) is a preliminary notice issued by the BIR when they find possible differences in your tax records.
Key points to understand:
Think of it as a warning or clarification stage, not yet a penalty.
The BIR uses this to open communication with the taxpayer before moving to a formal audit.
Common Reasons You Receive a BIR NOD
Many small and medium businesses receive NODs due to simple mistakes or inconsistencies.
Here are the most common reasons:
Mismatch between sales and declared income
Example: POS sales higher than reported income tax
Third-party data discrepancies
BIR compares your data with:
- Suppliers
- Customers
- Withholding tax reports
Incorrect VAT or Percentage Tax filing
Wrong computation or classification
Missing or late filings
Unfiled monthly or quarterly returns
Inconsistent books of accounts
Records don't match tax returns
Issues with ORUS or book registration
Unregistered books or outdated registration
Most of these are fixable, especially if addressed early.
