BIR Registration for Sole Proprietors & Freelancers (2026)

If you earn money from a business, a profession, or freelance work in the Philippines, registering with the Bureau of Internal Revenue (BIR) is not optional — it is the legal first step to declaring and paying tax on that income. The good news is that the process is more streamlined than it once was, thanks in part to the Ease of Paying Taxes (EOPT) Act (Republic Act No. 11976), which, among other simplifications, removed the ₱500 annual registration fee. This guide walks through every step a sole proprietor or freelancer needs to complete to register properly for the current year: getting a TIN, filing the right forms, receiving your Certificate of Registration, registering your books, and securing the authority to issue official receipts.

Who Must Register?

Anyone who earns business or professional income in the Philippines must register with the BIR as a taxpayer. This covers a broad group:

• Sole proprietors — individuals running a single-owner business under a registered trade name.
• Freelancers and independent professionals — consultants, designers, developers, tutors, and anyone selling services outside an employer-employee relationship.
• Online sellers and small traders — those selling goods, whether physical or digital.
• Mixed-income earners — employees who also run a business or practice a profession (they register the business side).

If you previously worked only as an employee, you already have a Tax Identification Number (TIN) — you do not get a new one. You simply register your new self-employed activity under your existing TIN. A person can have only one TIN for life.

The ₱500 Annual Registration Fee: Gone

For years, every registered business taxpayer paid an Annual Registration Fee (ARF) of ₱500 (due by January 31). That requirement was abolished by the Ease of Paying Taxes Act (RA 11976), with the BIR ceasing collection effective January 22, 2024. You no longer pay the ₱500 ARF, and you no longer file BIR Form 0605 to pay it. This is a permanent simplification, not a temporary waiver — one less step and one less fee at the start of each year. (Form 0605 itself still exists for other types of tax payments; it is only the ARF use that ended.)

The Registration Process, Step by Step

Beyond the BIR itself, two other agencies usually appear in a sole proprietor’s setup. Treat the steps below as the typical sequence; some can be done in parallel and several can now be completed online.

1. Secure your TIN (if you don’t already have one). Apply for a Tax Identification Number through the BIR’s online eRegistration system or at the Revenue District Office (RDO) that has jurisdiction over your business address. If you have ever been employed, you already have a TIN — reuse it.
2. Register your business name with the DTI. Sole proprietors register their trade name with the Department of Trade and Industry (DTI). This protects the name and is usually required to open a business bank account. (Freelancers practicing under their own name may not need a DTI registration.)
3. Obtain a Mayor’s Permit from the LGU. The city or municipality where you operate issues the Mayor’s Permit (business permit) — your local authority to do business. This typically involves the barangay clearance, the DTI certificate, and a fire/sanitary inspection.
4. File BIR Form 1901. This is the Application for Registration for self-employed and mixed-income individuals, professionals, and sole proprietors. You submit it to your RDO, along with your DTI and Mayor’s Permit documents. On this form you also elect your tax regime — the 8% flat tax or the graduated rates (a choice explained in depth in our sole proprietorship guide).
5. Receive your Certificate of Registration (COR). Also known as BIR Form 2303, the COR lists your registered tax types (for example, income tax, percentage tax or 8%, and possibly VAT). It must be displayed prominently at your place of business and is proof that you are a registered taxpayer.
6. Register your books of accounts. You must keep and register books of accounts (and, where relevant, subsidiary sales and purchase journals) with the BIR. These are where you record income and expenses. Registration can now be done digitally, and registered books must be stamped by the BIR before use.
7. Secure an Authority to Print (ATP) and issue receipts. To issue official receipts or sales invoices, file BIR Form 1906 to obtain an Authority to Print, then have your receipts printed by a BIR-accredited printer (or use a BIR-approved point-of-sale / e-invoicing system). Every sale or paid service must be supported by an official receipt.

Once these steps are complete, you are fully registered and ready to file returns. The BIR has been steadily digitizing the process, and the EOPT Act’s "file-and-pay anywhere" provisions further reduce the need to transact only at your home RDO.

Choosing Your Tax Regime at Registration

On Form 1901 you declare whether you will be taxed under the 8% flat tax or the graduated income-tax rates. This is one of the most consequential choices you make at registration, because it shapes every return you file afterward. In brief:

• 8% flat tax — 8% of gross sales/receipts above ₱250,000; simple (no deductions), available only when gross receipts are ₱3,000,000 or less.
• Graduated rates — 0/15/20/25/30/35% on net income after deductions (the 40% OSD or itemized expenses); available to all, and mandatory above ₱3,000,000.

You can change your election in subsequent years, so the choice at registration is not irreversible — but it sets your default until you change it. Because the right answer depends entirely on your numbers (gross receipts and real expenses), it pays to model both before registering. This site’s calculator compares the two regimes instantly.

What Happens After Registration

Registration is the beginning, not the end. As a registered self-employed taxpayer, you take on ongoing filing obligations. Typically these include filing your income tax return quarterly and annually (the 1701 series), and filing the appropriate percentage-tax or 8% returns. If your annual gross sales or receipts exceed ₱3,000,000, VAT registration becomes mandatory, adding monthly VAT returns and the 12% VAT on sales. Keeping your registered books up to date and your receipts in order is essential — the BIR can examine them, and accurate records are what let you claim deductions and credits correctly.

Common Mistakes to Avoid

• Operating before registering. Earning business income without a BIR registration exposes you to penalties and back taxes. Register before (or as soon as) you start billing clients.
• Applying for a second TIN. You keep one TIN for life. Reusing your existing TIN is correct; obtaining another is an error.
• Still budgeting for the ₱500 ARF. The fee was removed effective January 22, 2024 under RA 11976. Don’t pay it or file Form 0605 for it.
• Not displaying the COR. The Certificate of Registration (Form 2303) must be displayed at your place of business.
• Issuing receipts without an ATP. Print official receipts only after securing the Authority to Print (Form 1906), through a BIR-accredited printer.
• Neglecting to register books of accounts. Unregistered or unstamped books cannot support your deductions if examined.
