AccountingSuite provides the system functionality and documentation required to support this process.
What “BIR CAS-Ready” Means
The Bureau of Internal Revenue (BIR) does not accredit or certify accounting software vendors. Instead, each taxpayer registers its own Computerized Accounting System (CAS) with the BIR and receives an Acknowledgement Certificate (AC) for the specific system deployed at their business . “BIR CAS-Ready” means the software provides the functionality, documentation, and reports required to support this registration process.
Why CAS Registration Matters
CAS registration is mandatory for Large Taxpayers under RR No. 1-98, and it is required for any business that wants to issue electronic invoices . Registered CAS users also get an extended deadline of 30 days (instead of 15) for submitting BIR forms and reports .
