Simplified System Registration for Computerized Accounting System (CAS) Users
The BIR Revenue Memorandum Circular (RMC) No. 5-2021 and Revenue Memorandum Order (RMO) No. 9-2021 simplify the registration process for businesses using Computerized Accounting System (CAS). Starting in 2021, the BIR issues an Acknowledgement Certificate (AC) to businesses that comply with the requirements for using CAS.
The Philippines Localization SuiteApp supports this change. To specify the CAS document issued to your company by the tax authority in the Philippines, go to the Philippines Localization Setup page. There, you can select the CAS document and enter other relevant details. For more information, see Acknowledgement Certificate (AC) for CAS
The BIR also issues a Permit To Use (PTU) to businesses that use Computerized Accounting System (CAS). You must include PTU details, such as the date issued and PTU number, on printed VAT invoices and VAT official receipts. For more information, see Permit To Use (PTU) for CAS
