⚠ BIR Alert
Who Needs This Guide
BIR registration is not optional — it is a legal requirement for all income-earning individuals and businesses in the Philippines. Here’s who this guide is written for.
⚠️ One TIN only — for life. If you already have a TIN from previous employment, you do not get a new one when you register as self-employed. Applying for multiple TINs is illegal under the NIRC. The guide explains exactly how to update your existing registration via BIR ORUS.
If you earn income in the Philippines,
you need to be properly registered.
Freelancers & Online Sellers
Graphic designers, developers, virtual assistants, and Shopee/Lazada sellers must be BIR-registered regardless of income level. BIR Revenue Memorandum Circular 60-2020 specifically targets unregistered online business activity.
Must register regardless of income
New Business Owners & Entrepreneurs
Anyone starting a business in the Philippines — food stall, retail, services, consulting — must first register with DTI or SEC, then with BIR, then obtain a Mayor’s Permit. Getting the order wrong wastes time and money.
DTI → BIR → Mayor’s Permit
OFWs & Returning Entrepreneurs
Overseas Filipino Workers starting a business back home, and returning entrepreneurs who operated informally before, face unique registration questions around existing TINs, income declaration, and VAT thresholds.
Covers OFW & returning founder scenarios
Why Most Filipinos Get This Wrong What You Actually Need To Know I sell on Shopee and Lazada. Do I really need to register with DTI and BIR? Yes — BIR RMC 60-2020 requires all online sellers to register. The platforms may soon require your COR and TIN for compliance. Answered in full — Section 4. I already have a TIN from my old job. Do I apply for a new one for my business? No — you use the same TIN and update your registration. Applying for two TINs is illegal. Answered in full — Section 4. Should I choose the 8% flat tax or the graduated income tax rates? It depends on your income level and whether you have significant deductible expenses. Answered in full — Section 5. I earn in USD from foreign clients. Do I pay Philippine VAT? Zero-rated treatment may apply — but it requires BIR approval and specific conditions. Answered in full — Section 7. Do I need a Mayor’s Permit even if I work from home? Yes — it is required for your registered business address, including your home. Most RDOs also require it for BIR registration. Answered in full — Section 7.
Three costly mistakes
happening right now.
Mistake 01
Skipping DTI or SEC registration and going straight to BIR — or never registering at all
Many entrepreneurs — especially online sellers — assume they only need a BIR TIN. But the BIR registration process requires your DTI Certificate (sole prop) or SEC Certificate (corporation) first. Operating without completing all three registrations (DTI/SEC → Mayor’s Permit → BIR) exposes you to fines, closure orders, and being assessed for back taxes going back to the date you started earning.
Mistake 02
Not knowing the Authority to Print (ATP) requirement — and issuing invalid receipts
Once you receive your BIR Certificate of Registration, you must separately apply for an Authority to Print (ATP) before you can legally issue Official Receipts or Sales Invoices. Using pre-printed receipts from a stationery store or issuing handwritten receipts without an ATP number is a BIR violation — even if you have a COR. Many businesses run for months without knowing their receipts are non-compliant.
Mistake 03
Choosing the wrong tax scheme — and locking yourself into higher tax than necessary
The TRAIN Law introduced the 8% flat income tax option for eligible self-employed individuals — a significant simplification that eliminates the Percentage Tax and lets you pay a single 8% rate on gross income. But many freelancers and sole proprietors don’t know this election exists, or miss the window to elect it in the first quarterly return. The guide explains exactly who qualifies, how to elect it, and when it is (and isn’t) the right choice.

doesn’t answer clearly.

These are the questions
Philippine entrepreneurs are actually asking.
I sell products on Lazada and Shopee. Do I need to register with DTI and BIR?
Yes — selling on e-commerce platforms is taxable business activity in the Philippines. BIR Revenue Memorandum Circular 60-2020 specifically clarified that all online sellers, regardless of platform, must be registered with the BIR. You should first register your business name with DTI (if operating as a sole proprietor), obtain a Barangay Clearance and Mayor’s Permit from your LGU, then register with BIR at your local RDO. The platforms — Lazada and Shopee — may also require your BIR Certificate of Registration and TIN for compliance purposes as enforcement tightens.
I’m a freelance designer earning PHP 2.5 million this year from clients abroad. Do I pay VAT on my invoices to foreign clients?
At PHP 2.5 million, you are below the PHP 3 million mandatory VAT threshold and subject to the Non-VAT regime — the 3% Percentage Tax on gross receipts (or the applicable reduced rate per current BIR issuances). If your foreign client income qualifies as zero-rated under the NIRC (services rendered exclusively to non-resident foreign clients with consideration paid in foreign currency inwardly remitted to the Philippines), you would charge 0% VAT rather than 12% — and could recover input VAT on your local purchases. Zero-rating requires BIR approval and has specific eligibility conditions. The guide covers both scenarios in full.
I already have a TIN from my previous employer. Do I need to apply for a new one when I register as self-employed?
No — you must use your existing TIN. The TIN is a lifetime identifier and applying for a second TIN is illegal under the NIRC. Instead, update your BIR registration via ORUS to add the self-employed or business registration on top of your existing TIN. Your income tax filing changes from BIR Form 1700 (compensation) to BIR Form 1701A or 1701 (self-employed or mixed income).
What is the 8% flat tax option and should I choose it as a freelancer?
Under the TRAIN Law, self-employed individuals and professionals with gross sales/receipts not exceeding PHP 8 million may elect to pay income tax at a flat 8% rate in lieu of graduated rates AND percentage tax. This is a significant simplification — no separate percentage tax, one single 8% rate, simpler computation. You cannot choose this if you are VAT-registered or if you receive compensation income from an employer. The election is made in your first quarterly return for the year.

Questions About This Guide
Before you buy
Is this based on current BIR, DTI, and SEC guidance?
Yes. Every answer is based on BIR, DTI, and SEC guidance current as of 2025/26, including the National Internal Revenue Code (NIRC), TRAIN Law (R.A. 10963), Revised Corporation Code (R.A. 11232), and BIR Revenue Memorandum Circulars. Official source links are included throughout. As with all tax and compliance matters, verify against current guidance at bir.gov.ph before taking action.
I’m not sure whether to go DTI or SEC. Will this help me decide?
Yes — Section 1 is entirely dedicated to this decision. It covers sole proprietorship vs OPC vs corporation across 10 criteria including liability, tax rates, funding ability, and cost. If you’re a solo founder unsure between DTI and OPC, the guide walks through that comparison in detail.
How do I receive the guide after purchasing?
Instantly. After your payment is processed, you’ll receive a download link on the order confirmation page and in your purchase receipt email. The guide is a PDF, readable on any device — phone, tablet, or desktop. No account is required to download it.
Is this a replacement for professional accounting or legal advice?
No, and it doesn’t claim to be. This guide is an information resource covering the BIR, DTI, SEC, and LGU registration process for Philippine businesses. For complex situations — multi-entity setups, foreign ownership questions, back-tax regularisation — you should seek a qualified Philippine CPA or corporate lawyer. This guide helps you arrive at those conversations better prepared.
What if BIR or SEC changes the rules after I buy?
ThriveOnz Group / Thrive Business Asia will update the guide if BIR, DTI, or SEC makes material changes to registration requirements, tax thresholds, or penalty regimes. Updates are made available to existing purchasers. The guide includes its publication date so you always know how current it is.
I operated informally for a year without registering. Can this guide still help me?
Yes — Section 7 covers exactly this scenario. The guide explains the BIR’s Voluntary Assessment programs, the implications of retroactive registration, and how to approach regularisation. If you have more than 2 years of unreported income, the guide recommends engaging a tax consultant before proceeding and explains why.
