Depending on the software you want to register, you will need to fill out and accomplish the BIR Form 1900 or the Application for Authority to Adopt Computerized Accounting System (CAS) and/or Components Thereof/Loose-leaf Books of Accounts.

Other requirements include a photocopy of the previously issued permit for the mother or sister company or branch that uses the same software or system, if applicable.

To apply for system enhancement or modification, you need to submit a photocopy of the previously issued Permit to Adopt CAS.

Procedures for Initial Application

Suppose your branch is applying for the Permit to Use CAS for the first time. In that case, you need to file your application at the Revenue District Office (RDO), which has jurisdiction over your branch’s head office (HO). You can also file your application at the Large Taxpayer Assistance Division (LTAD I or II). Another option is to submit at the Large Taxpayers District Office (LTDO).

However, if your branch adopts the CAS ahead of your head office, you should apply with the RDO with jurisdiction over you. You should submit a certification that states the head office is not using the CAS you are applying for. Then, when the head office later adopts the same CAS as yours, the BIR will issue a permit to your head office and include a new permit for your branch. This permit shall supersede the permit issued previously.

Then, when your branch adopts a different CAS from your head office, you will need to apply for a permit to adopt said CAS at the BIR Office who has jurisdiction over your branch.

The BIR will issue the Permit for CAS after they evaluate a demonstration of the applied system or software. They will then recommend it for approval to the CSET.

Procedures: Application for System Enhancement or Modification

Now, suppose you want to apply for system enhancement or modification on the previously approved software. In that case, you need to submit a letter to the RDO that previously issued the permit. Describe in the letter your planned enhancement or modification of the software or system. Ensure that you attach a photocopy of the previously issued Permit to Adopt CAS with the said letter.

For more information regarding this matter, you can refer to Revenue Memorandum Order No. 21-2000 with subject line Processing and Approval of Taxpayer’s Application for Permit to Adopt Computerized Accounting System and/or Components Thereof. You can also check out the BIR’s Frequently Asked Questions (FAQs) section on the subject.
