What Is CAS and BIR?
The Computerized Accounting System (CAS) is closely tied to BIR regulations, requiring businesses in the Philippines to use digital accounting tools that meet government standards to ensure accurate records and compliance.
What is a Computerized Accounting System (CAS)?
A computerized accounting system (CAS) is software that can record, store, and retrieve financial data accurately and quickly with minimal to no errors. Additionally, it simplifies the accounting process steps.
One of CAS’s main benefits is its ability to automate many accounting tasks. For example, it can automatically calculate totals, generate financial statements, and even help with tax filing.
With the right computerized accounting system (CAS), your business can improve accuracy, save time, and stay compliant with BIR regulations.
What is Bureau of Internal Revenue (BIR)?
Founded in 1904, the BIR oversees tax collection in the Philippines, ensuring fair compliance while supporting taxpayers through education, online payment options, and accessible customer services.
One of the BIR’s key responsibilities is enforcing tax laws. This means checking whether individuals and businesses are paying the correct taxes and conducting audits and investigations to ensure compliance.
The BIR offers guidelines and tools to help businesses maintain proper accounting records, such as the Computerized Accounting System (CAS). This system helps businesses keep accurate financial records and makes it easier to file tax returns.

Computerized Accounting System BIR Requirements
Core CAS Components
To comply with BIR CAS requirements, Revenue Memorandum Order (RMO) No. 9-2021 outlines four essential components that must be synchronized for proper record-keeping and reporting.
- General Journal and Subsidiary Records: Accountants must maintain both the general journal and subsidiary records.
- Comprehensive Accounting Records: This includes books for sales, inventory, purchases, accounts receivable, accounts payable, payroll ledgers, and subsidiary ledgers.
- Application Systems: Identify systems responsible for generating billing statements, cash vouchers, invoices, official receipts, and other entries for the subsidiary ledger.
- Integration of CRM and POS Systems: Ensure that Cash Register Machines (CRM) and Point of Sale (POS) systems are connected to the CAS.
Documentary Requirements
For the initial application to use a Computerized Accounting System BIR or its components, you need to submit the following:
- Filled out BIR Form 1900 and/or BIR Form 1907
- Company profile
- Photocopy of BIR Certificate of Registration
- Photocopy of previously issued permit, if applicable
- Photocopy of current registration fee payment
- Business location map
- Inventory of unused approved invoices and receipts, if applicable
- List of branches using CAS, if any
After submitting complete documentary requirements, the BIR usually issues an Acknowledgement Certificate (AC) within three working days. In the 2024 BIR Citizen’s Charter, the estimated processing time is 2 days and 45 minutes for walk-in applications and 3 days for ORUS applications, although actual processing may still vary depending on document completeness and system availability.
Simple CAS Application Flow
After preparing the required documents, businesses can follow a simple CAS registration flow to make the process easier to understand.
- Register at the correct office: Submit the application to the Revenue District Office (RDO) or Large Taxpayer Office where the business is registered. Businesses may also file through the BIR’s ORUS platform for online processing.
- Submit the requirements: Provide the documentary and technical requirements listed in this section. The BIR will review the submission and may return incomplete applications for correction.
- Wait for processing: Walk-in applications usually take around 2 days and 45 minutes based on the 2024 BIR Citizen’s Charter, while ORUS applications usually take up to 3 days.
- Receive the approval document: Once approved, the BIR issues an Acknowledgement Certificate (AC), which now serves as the approval document for CAS registration.
- Proceed with the next compliance step: After receiving the AC, the business may use the registered system and keep it aligned with BIR rules. The BIR may still conduct post-evaluation, and any major system enhancement may require a new application.
Technical Requirements
- Application name and software used (development and database)
- Application functions and features
- System flow/s

Policy of Computerized Accounting System (CAS) by BIR
The Bureau of Internal Revenue (BIR) ensures the government has the funds needed for public services by collecting various taxes, such as income tax, value-added tax (VAT), and business taxes.
One key policy to achieve this goal is implementing a BIR computerized accounting system and an Electronic Invoice System BIR (EIS), both required to ensure accurate and transparent tax reporting. Additionally, every company is now required to implement BIR-accredited POS (Point of Sale) to print their invoices.
Similarly, the EIS policy requires businesses to issue invoices electronically, enhancing transparency and efficiency in tax reporting. Both CAS and BIR electronic filing must be registered and approved by the BIR before use, ensuring they meet all regulatory requirements.
Key objectives of the CAS policy
Here are several main objectives of the Computerized Accounting System policy by BIR:
- Enhance accuracy: Ensure that all financial transactions are accurately recorded and reported.
- Improve compliance: Make it easier for businesses to comply with tax laws and regulations.
- Increase efficiency: Streamline the accounting process, reducing manual errors and saving time.
