BIR Form 1901: Requirements, Filing via ORUS or RDO, and Penalties

BIR Form 1901 is the Bureau of Internal Revenue’s application for registration used by sole proprietors, licensed and freelance professionals, mixed income earners, estates, and trusts in the Philippines. Filing it gives you a Taxpayer Identification Number (or updates an existing one) and places you in the BIR system as someone with tax obligations beyond employee withholding. You must register on or before your first sale or first payment for services, and you can now do the whole thing online through the BIR’s Online Registration and Update System (ORUS).

Who Files Form 1901

The form itself lists the categories of people who use it:1Bureau of Internal Revenue. BIR Form 1901 – Application for Registration

  • Single proprietors, from sari-sari store owners to online sellers.
  • Professionals, both PRC-licensed practitioners (doctors, lawyers, engineers, accountants) and non-licensed professionals such as freelance writers, consultants, and graphic designers.
  • Mixed income earners who draw a salary from an employer and also earn from a side business or freelance work.
  • Estates of deceased taxpayers and trusts that generate income through managed assets, which register under a new TIN.
  • Non-resident aliens engaged in trade or business in the Philippines, who need a 9(g) work visa to register.2Bureau of Internal Revenue. BIR Citizen’s Charter (2026 Edition)

If you earn only compensation income from an employer and have no side business or professional practice, Form 1901 is not for you. Your employer registers you using BIR Form 1902 instead.3Bureau of Internal Revenue. Application for Taxpayer Identification Number (TIN) of Local Employee

When You Must Register

The rule is registration on or before the commencement of business.4ChanRobles Virtual Law Library. National Internal Revenue Code of 1997 – Title III, Chapter 2 The BIR’s own guidance for professionals states it as “on or before the first sale transaction occurred, or within thirty days from the issuance of a Mayor’s Permit or Professional Tax Receipt,” whichever fits your situation.5Bureau of Internal Revenue. Tax Guide for Professionals If you’re already earning without having registered, you are technically in violation. Register as soon as you can to limit exposure to the penalties described further down.

What to Prepare

The BIR’s checklist is shorter than most people expect, and it’s the same whether you file online or walk in.6Bureau of Internal Revenue. Checklist of Documentary Requirements

  • Form 1901 itself. Two original copies if you file manually; a digital form if you use ORUS.
  • Any valid government-issued ID showing your full name, address, and birthdate, such as a PhilID, passport, or driver’s license. If the ID does not show your address, bring separate proof of residence.
  • A valid PRC ID if your profession is regulated by the Professional Regulation Commission.
  • Invoices. You can buy BIR Printed Invoices at the New Business Registrant Counter, or bring a final sample of your own invoice layout for approval before printing through a BIR-accredited printer.

Depending on your situation, you may also need:6Bureau of Internal Revenue. Checklist of Documentary Requirements

  • Your DTI Certificate if you registered a business name with the Department of Trade and Industry.
  • A 9(g) work visa for foreign nationals.2Bureau of Internal Revenue. BIR Citizen’s Charter (2026 Edition)
  • A Special Power of Attorney and the representative’s valid ID if someone else is filing for you.
  • Franchise or special permits. Common carriers need a Certificate of Public Convenience; businesses in special economic zones need proof of PEZA, TIEZA, or similar registration.
  • A BMBE Certificate of Authority if your business is registered as a Barangay Micro Business Enterprise.

The only fee at registration is ₱30 for the loose documentary stamp tax affixed to your Certificate of Registration. The ₱500 annual registration fee that used to be due every January was abolished in 2024 by the Ease of Paying Taxes Act (Republic Act 11976).7Bureau of Internal Revenue.

Filling Out the Form

Form 1901 collects three kinds of information: personal details, business details, and tax type selections. Getting each part right the first time matters, because errors can trigger incorrect assessments or force you to file amendments later.

Your personal information (full legal name, birthdate, address) must match your supporting IDs exactly. In the business section you’ll enter your registered trade name if you have one, the physical address where you will operate, and your planned start date. You’ll also select the Philippine Standard Industrial Classification (PSIC) code for your industry, which determines how the BIR categorizes your account.

The tax type section is where most first-time registrants slow down. You’ll check the specific taxes you’re obligated to pay. Almost everyone checks Income Tax. Beyond that, you pick one of two indirect taxes based on expected revenue:

  • Percentage Tax, if your annual gross sales or receipts will stay below ₱3,000,000.
  • Value-Added Tax (VAT), which becomes mandatory once your gross sales exceed or are expected to exceed ₱3,000,000 in any 12-month period.

The form also asks whether you want to elect the 8% flat income tax rate. First-year businesses make that election at registration, so decide before you file. The tradeoffs are covered below.

Filing Online Through ORUS

The Online Registration and Update System at orus.bir.gov.ph lets you complete registration without visiting an office.7Bureau of Internal Revenue. Online thru ORUS – Application for Registration Create an account, fill out the form, and upload scanned copies of your documents. For the ID upload, you’ll take a selfie while holding your ID. A BIR officer reviews the application and checks for duplicate TIN records. Once approved, you’ll get an email notification, pay the ₱30 documentary stamp tax online, and download your Certificate of Registration and Authority to Print directly from your ORUS profile.

Filing in Person at the RDO

If you’d rather register face-to-face, bring your completed form and documents to the Revenue District Office that has jurisdiction over your business address.1Bureau of Internal Revenue. BIR Form 1901 – Application for Registration The officer-of-the-day reviews your papers, verifies your identity, and processes the registration. You’ll pay the ₱30 documentary stamp tax on-site. You may be asked to sit through a short taxpayer briefing on your rights and obligations. The RDO then issues your Certificate of Registration and Authority to Print.

After You’re Registered

Getting the Certificate of Registration is not the finish line. Several steps follow.

Display the Certificate

Your original Certificate of Registration must be posted prominently at your place of business, in clear view of the public. If you operate online, display it on your website, social media page, or online platform. The BIR can issue closure or takedown orders against unregistered or non-compliant businesses, suspending operations for at least five days until the violation is corrected.

Invoices and the Authority to Print

Everyone in business must secure an Authority to Print before producing official invoices.8Bureau of Internal Revenue. Processing of Application of Authority to Print (ATP) Invoices You’re required to issue a registered invoice for every sale of goods or services worth ₱100 or more. ORUS registrants receive the Authority to Print with their approved registration. Walk-in registrants can buy BIR Printed Invoices at the RDO counter or submit their own layout for approval and printing by an accredited printer.6Bureau of Internal Revenue. Checklist of Documentary Requirements

Books of Accounts

You must register your books of accounts, and the BIR now requires this online through ORUS rather than the old manual stamping. For new registrants using manual books, the deadline is before the filing of your initial quarterly income tax return or your annual return, whichever comes first. Computerized and loose-leaf books follow different deadlines in later years.

The 8% Flat Rate Decision

One of the most consequential choices on Form 1901 is whether to elect the 8% flat income tax rate. First-year businesses make the election at registration; existing taxpayers make it on their initial quarterly return.5Bureau of Internal Revenue. Tax Guide for Professionals

The 8% rate applies to gross sales or receipts and other non-operating income in place of both the graduated income tax and the percentage tax. It’s available to self-employed individuals and professionals whose gross sales don’t exceed the ₱3,000,000 VAT threshold during the taxable year.9Bureau of Internal Revenue. Revenue Memorandum Circular No. 020-2026 For mixed income earners, the 8% rate applies only to business or professional income; compensation is still taxed under the graduated rates.

Not everyone qualifies. The following cannot elect the 8% rate:9Bureau of Internal Revenue. Revenue Memorandum Circular No. 020-2026

  • VAT-registered taxpayers, regardless of actual gross sales.
  • Partners of a General Professional Partnership.
  • Individuals exempt from income tax under the Tax Code or special laws.

The 8% option simplifies record-keeping because you pay based on gross sales instead of tracking every deductible expense. If your business carries heavy expenses that pull your net income well below gross, the graduated rates with itemized deductions might yield a lower total tax. Run the numbers for your own situation before locking in your choice.p>

Penalties for Not Registering

Operating a business or practicing a profession without BIR registration carries real consequences. Section 258 of the Tax Code sets a criminal penalty of ₱5,000 to ₱20,000 in fines and imprisonment of six months to two years for pursuing business without proper registration.10ChanRobles Virtual Law Library. National Internal Revenue Code of 1997 – Title X

In practice, the BIR more often imposes compromise penalties, which are administrative fines that settle the violation without criminal prosecution. The amount depends on where the business is located:11Bureau of Internal Revenue. Annex C – Schedule of Compromise Penalties

  • Cities: ₱20,000
  • First-class municipalities: ₱10,000
  • Second-class municipalities: ₱5,000
  • Third-class municipalities: ₱2,000

On top of the fine, the BIR can issue a closure order against unregistered physical businesses or a takedown order for unregistered online sellers, suspending operations for at least five days. The suspension lifts only after full registration compliance. Against a ₱30 documentary stamp, delaying registration is one of the most expensive shortcuts a new business owner can take.
