Connecting to BIR's EIS

3 quick questions. Pick an answer to see why.

1. Kuting Kitchen's PTI was issued on 20 November 2026. By when must it get EIS certification?

By 31 December 2026 Within 6 months of the PTI: by 20 May 2027 There's no deadline once the PTI is issued

RMC 98-2026 requires EIS certification within 6 months from the PTI. Missing it is a ground for revoking the PTI.

2. A buyer returns part of an order after the e-invoice was issued. What does Kuting Kitchen do?

Edit the e-invoice to the new amount Delete it and issue a fresh one Issue a credit note that refers to the original e-invoice

An issued e-invoice is never deleted or altered. A decrease is a credit note referencing the original; an increase is a new e-invoice.

3. A software company offers to run e-invoicing for many sellers on its own servers. What should a seller check?

That BIR has accredited it as an e-invoicing service provider That it has a Shopee partner badge Nothing: the seller's PTI covers the provider

Under RMC 110-2026, an e-invoicing service provider needs BIR accreditation before it serves taxpayers. Ask to see its accreditation certificate.
