Steps to filing BIR Form 1901 for self-employed and mixed-income individuals

1. Submit all the requirements to the New Business Registrant Counter of the RDO

The registration officer will then check if your forms and supporting documents are complete. Expect to be asked some questions that will determine if you’re registering for the correct taxpayer type and to compute the penalty fee in the case of late registration.

Your information will also be checked against the BIR database to verify if you’re issued a TIN before. If not, the officer will encode your data, generate your TIN, and write down the TIN on the BIR Form 0605 for the ARF payment.

However, if you have an existing TIN, you won’t be issued a new one. The officer will just update your taxpayer records using the documents you provided.

2. Pay the fees

Go to the RDO’s authorized agent bank and pay the registration fee. Wait for the teller to issue the proof of payment, which is an official receipt along with the machine-validated BIR Form 0605.

Note: If you’re previously issued a TIN, save time by paying the ARF in advance before you register with the BIR. Just fill out the BIR Form 0605 and pay through the AAB, the bank’s online banking facility, or GCash.

Return to the RDO and submit your proof of payment. You should also pay the DST and certification fee at the RDO.

3. Attend the taxpayer’s briefing

Attend the briefing for new business registrants. The briefing will inform you of your rights and duties as a taxpayer. Attendance is required before you’re issued the BIR Form 2303 and other registration papers.

4. Receive your BIR registration documents

After the briefing, return to the registration officer to claim the following registration documents:


What to do after your BIR registration

Display your BIR Certificate of Registration, together with the “Ask for a Receipt” Notice, in a visible area in your office or place of business. You may also use the BIR Form 2303 as your reference guide for the tax returns you must file, taxes you have to pay, and the deadlines for those.

Also, if applicable, you must issue invoices or receipts for every payment received that is worth more than Php 1001.

You’ll also be required to keep books of accounts and submit a yearly account information return or financial statements. However, if your gross annual sales or receipts are higher than Php 3,000,000, your books of accounts must be audited and examined yearly by independent Certified Public Accountants and their income tax returns accompanied with a duly accomplished Account Information Form (AIF)2.

Before that, you need to apply for the registration of books of accounts at the RDO where your business is registered. Present your journal, ledger, or any equivalent books of accounts for stamping by the same RDO.
