A New Line on the Invoice: BIR Expands Mandatory Invoicing Information
The Bureau of Internal Revenue (“BIR”) has issued Revenue Regulations (“RR”) No. 6-2026, further strengthening the invoicing requirements introduced under the Ease of Paying Taxes (“EOPT”) Act and implemented through RR No. 7-2024, as amended by RR 11-2024.
RR No. 6-2026 specifically amends Section 6(B) of RR No. 7-2024 or Section 237 of the Tax Code, which prescribes the information that must appear on invoices. Under the new regulation, the amount of Creditable Withholding Tax (“CWT”), if applicable, must now be shown as a separate item on the invoice.
Although the amendment is concise, its practical implications are significant. Taxpayers may need to revisit not only their manual invoice formats, but also their loose-leaf, computerized accounting, point-of-sale and electronic invoicing configurations to ensure that withholding tax information is properly captured whenever applicable and aligned with the amounts reported in the invoice.
For unused or unissued invoices existing as of the effectivity of RR No. 6-2026, taxpayers may continue using them until fully consumed, provided that the phrase “Less: Withholding Tax” is conspicuously stamped on the face of the invoice. All newly printed invoices thereafter must already reflect the same phrase prior to use.
Revisiting RR NO. 7-2024: The Invoice as the Primary Tax Document
RR No. 6-2026 should be read together with RR No. 7-2024, which implemented the invoicing provisions introduced under the Ease of Paying Taxes Act.
Under RR No. 7-2024, the invoice serves as the primary document evidencing sales of goods and services. VAT-registered taxpayers are required to issue duly registered VAT invoices containing the prescribed information necessary to properly document the transaction.
The key invoicing requirements may be summarized as follows:

The additional requirement under RR No. 6-2026 therefore makes it necessary for taxpayers to ensure that their invoicing systems properly capture both the gross transaction amount and the applicable withholding tax deduction.
Moving Forward
RR No. 6-2026 reinforces the increasing importance of complete and accurate invoice documentation in Philippine tax compliance.
With invoices serving as the primary basis for recording sales, VAT and withholding tax information, taxpayers should exercise greater care in ensuring that all prescribed details are properly reflected. Strengthening invoice review controls can help minimize exposure to tax assessments, avoid potential disallowance of tax claims and promote better overall compliance with BIR requirements.
In short, every line on the invoice matters.
