HOW-TO

How to Register as Self-Employed or a Professional (BIR Form 1901)

Freelancers, sole proprietors and licensed professionals register with BIR using Form 1901. Here is how to do it without the guesswork.

Step by step

1. Check your TIN status firstYou may hold only one TIN for life, and multiple TINs are illegal. If you were previously employed, your TIN already sits in a former employer's RDO — update that record rather than applying for a new number.
2. Gather your documentsPrepare the current BIR Form 1901, a valid government ID showing your name, address and birthdate, and proof of address if the ID lacks one. Licensed professionals also need a valid PRC ID. Confirm the full checklist on bir.gov.ph, as it changed in 2025.
3. Choose online or manual filingRegister through ORUS at orus.bir.gov.ph, or file manually at the RDO covering your residence or business address. Online registrants create an ORUS account and upload their documents.
4. Submit and pay any required feeSubmit Form 1901 with your attachments. Online registrants typically pay a loose documentary stamp tax (reported around PHP 30 as of 2026). Fees change, so confirm current amounts before paying.
5. Get your Certificate of Registration (Form 2303)Once approved, your RDO issues, or ORUS lets you download, the COR listing your TIN and the returns you must file. Keep it safe.
6. Set up invoicingComply with the invoicing requirement — use BIR Printed Invoices or secure an Authority to Print / accredited invoicing system before issuing receipts to clients.
7. Start filing your returnsFile the percentage tax, quarterly and annual income tax returns shown on your COR by their deadlines. Keep records of income and expenses from day one.

Who Form 1901 is for

If you earn money on your own account rather than purely as an employee, Form 1901 is almost certainly the registration form that applies to you. It covers self-employed individuals and sole proprietors, licensed professionals in private practice, people who earn both a salary and business or professional income, and certain estates and trusts. Freelancers who have started taking on clients fall squarely within it. Registering is not just a formality; it is what lets you issue valid receipts, claim that you operate legitimately, and file the returns that keep you in good standing.

The Bureau revised its registration forms in October 2025, so the version of Form 1901 you use matters. Downloading the current form from bir.gov.ph, rather than reusing an old PDF someone sent you, avoids the frustration of having an outdated form bounced back at the counter.

Check your TIN before anything else

Many first-time registrants trip over the one-TIN rule. Every taxpayer may hold only one Taxpayer Identification Number for life, and having more than one is illegal. If you have ever been formally employed, a TIN was almost certainly issued for you and it still sits in the records of a former employer’s RDO. In that case you do not apply for a new number when you go self-employed. Instead you keep your existing TIN and update your registration, which usually means transferring your record to the RDO covering your address and adding your self-employed registration on top. Applying for a second TIN would put you on the wrong side of the law, so pause and confirm your status first.

Documents and the online option

The core requirements are the current Form 1901, a valid government-issued ID that shows your name, address and date of birth, and proof of your address if the ID does not carry one. Professionals regulated by the Professional Regulation Commission also present a valid PRC ID. You can file manually at the RDO covering your residence or place of business, or register through the Online Registration and Update System at orus.bir.gov.ph, where you create an account and upload your documents. Because the checklists were updated in 2025, confirm the exact list on bir.gov.ph before you go, and bring complete paperwork; incomplete applications are returned without being processed, which only delays you.

Fees to expect, with a caveat

Online registrants are generally asked to settle a small loose documentary stamp tax, reported at around thirty pesos as of 2026, before the electronic Certificate of Registration is released. You may also encounter other charges depending on current rules. Fees and the forms attached to them change over time, and some older obligations have been revised, so treat any figure you read, here or elsewhere, as provisional until you confirm the current amount with the Bureau. Never assume last year’s fee still stands.

After registration: invoicing and filing

Once your registration is approved you receive Form 2303, the Certificate of Registration, which spells out the returns you must file. Before you bill your first client you need to sort out invoicing, either by using BIR Printed Invoices or by securing authority to issue receipts through an approved arrangement. From there, the returns on your COR, which for self-employed people often include quarterly and annual income tax and sometimes percentage tax, become part of your routine. Keeping clean records of what you earn and spend from the very beginning makes every one of those filings easier and protects you if your return is ever reviewed.

Staying compliant once you are registered

Registration is the entry ticket, but staying in good standing is the ongoing work. Self-employed taxpayers typically juggle more than one return across the year, which makes a simple system for tracking deadlines genuinely valuable. Set reminders ahead of each due date, keep your receipts and invoices in order as you go rather than scrambling at filing time, and separate your business money from your personal spending so your figures are easy to reconstruct. If your income grows or your situation changes, revisit whether the tax options you chose at registration still suit you, and update your records when anything material shifts. Good habits early on turn each filing into a routine task instead of an annual ordeal.

Scope and safety

This is a general guide to registering as self-employed, not tax advice. Which taxes apply to you, whether you qualify for particular options, and how much you ultimately owe depend on facts specific to your situation, and those are questions for a licensed accountant or your RDO. Be wary, too, of anyone promising to secure your registration for a fee without you appearing or submitting your own documents; that is the hallmark of a fixer, not a legitimate service. Deal only through bir.gov.ph, orus.bir.gov.ph and your RDO. Gabay is an independent civic how-to site and not a government agency.
