Tax Identification Number (TIN) Philippines
Updated October 16, 2026
On this page
The unique number the BIR assigns to each taxpayer, used on every return, statement and document filed with the BIR. A person keeps one TIN for life.
For the fields shown in current registration, see the BIR Taxpayer Portal. Older three-digit branch-code instructions appear in the BIR eFPS help.
What is a Tax Identification Number (TIN)?
A Tax Identification Number (TIN) is the number the Bureau of Internal Revenue (BIR) assigns to each person required to file a return, statement or other document, for proper identification for tax purposes (NIRC Sec. 236, as amended by RA 11976). The TIN goes on every return and document filed with the BIR. Only one TIN is assigned to a taxpayer, whatever the number of transactions, and a person who already has a TIN may not apply for another (RR 7-2012).
TIN number format and example
The TIN itself is a nine-digit number, written in the format XXX-XXX-XXX. Registered businesses add a branch code after it to identify the head office and each branch. The same base number stays with the taxpayer for all tax types.
Who Needs a TIN?
Every person subject to any internal revenue tax must register with the BIR: within 10 days from the date of employment, on or before starting a business, before paying any tax, or when filing a return (NIRC Sec. 236(A), as amended by RA 11976). This covers employees, self-employed professionals, business owners, and individuals selling property or paying estate or donor's tax. When a registered taxpayer dies, the executor or administrator registers the estate, which receives its own TIN.
How to Obtain a TIN
Employees register through BIR Form 1902, usually with their employer's help; self-employed individuals and professionals use BIR Form 1901; corporations and partnerships use BIR Form 1903; and individuals who need a TIN for a one-time transaction or a government transaction use BIR Form 1904. Registration can be done online through the BIR's Online Registration and Update System (ORUS) or at the Revenue District Office (RDO).
TIN and Tax Compliance
Your TIN is used for all tax-related transactions: filing income tax returns, paying taxes, registering a business, and claiming refunds or credits. Employers report your compensation and tax withheld under your TIN, and payors of fees list your TIN in their withholding returns, which lets the BIR match income reported by others with your own returns.
TIN Validity and Permanence
A TIN does not expire. It stays the same when you change employers, move to another RDO, start a business or retire; you update your registration instead of getting a new number. Registration for a tax type is cancelled by filing an application for registration information update when you stop being liable for it (NIRC Sec. 236, as amended by RA 11976).
TIN and Financial Transactions
The TIN must be shown on documents listed in the Tax Code, such as documents registered with the Register of Deeds or the Assessor's Office (NIRC Sec. 236). Banks, brokers and other payors ask for it so they can report income payments and taxes withheld. Securing more than one TIN violates BIR regulations and is penalized under the Tax Code (RR 7-2012).
Special Cases: OFWs and Non-Resident Aliens
Overseas Filipino Workers with Philippine-source income, such as rent from a property in the Philippines, need a TIN to file returns on that income. OFWs earning solely from abroad are not required to file an income tax return (NIRC Sec. 51(A)(2), as amended by RA 11976). Non-resident aliens earning Philippine-source income also need a TIN. The Tax Code directs the Commissioner to make registration available to taxpayers who are not residing in the country (NIRC Sec. 236(A)).
TIN vs. Other Identification Numbers
Do not confuse your TIN with your Social Security System (SSS) number, PhilHealth number or Pag-IBIG MID number. Each serves a different agency. Your TIN is used only for tax identification and BIR transactions.
Why it matters
Your TIN is your permanent tax identity in the Philippines. You need it to register as an employee or a business, file returns, pay taxes and claim refunds. The BIR uses it to match the income your employer and clients report with your own returns. Protecting your TIN helps prevent unauthorized filings in your name.
How it works
Register Online or at Your RDO
Register through the BIR's Online Registration and Update System (ORUS) or at the Revenue District Office (RDO) for your residence or business address. Employees use BIR Form 1902, self-employed individuals and professionals BIR Form 1901, and corporations and partnerships BIR Form 1903.
Receive Your TIN Assignment
The BIR assigns your TIN. Employees receive their TIN for payroll and withholding. Self-employed individuals, professionals and businesses also receive a Certificate of Registration (BIR Form 2303) listing their tax types.
Use Your TIN for All Tax Transactions
Provide your TIN when filing returns, paying taxes, registering a business, issuing invoices or claiming tax credits. Your employer uses it to report your compensation and the tax withheld.
Keep Your Registration Updated
When you change employers, move to another RDO or start a business, update your registration under the same TIN instead of applying for a new one (RR 7-2012). File required returns on time and keep your contact details current with the BIR.
Examples
Salaried Employee at ₱600,000 Annually
Juan dela Cruz earns ₱600,000 a year as an accountant. He registered within 10 days of starting work, and his employer reports his compensation and tax withheld under his TIN (format 123-456-789). With one employer and correct withholding, his Form 2316 serves as his substituted filing, so he does not file BIR Form 1700 (NIRC Sec. 51-A).
Self-Employed Consultant Earning ₱800,000
Maria Santos is a freelance management consultant earning ₱800,000 a year. She registers as a professional on BIR Form 1901 under the TIN she already had as a former employee and receives a Certificate of Registration. She uses the TIN on her invoices, her quarterly returns and her annual return (NIRC Sec. 236; RR 7-2012).
OFW with Philippine Rental Income
Anna Reyes, an OFW in Singapore, owns a residential property in Manila that earns ₱240,000 a year in rent. Her salary abroad is not taxed in the Philippines, but she files returns on the Philippine rental income under her TIN (NIRC Sec. 23(C)).
Retiree with Investment Income
Roberto Santos, age 68, receives ₱150,000 a year in cash dividends from listed companies and interest on bank deposits. These are subject to final tax withheld at source, so he does not need to file an annual return for them, but banks and brokers record his TIN when they report the income and tax withheld (NIRC Sec. 51(A)(2)).
Business Owner with Multiple Income Sources
Carla Mendoza owns a retail store (₱1,200,000 annual sales) and rents out a commercial space (₱300,000 annual rental income). She uses one TIN for all business and rental income, and registers each business activity and branch under it (RR 7-2012).
Common misconceptions
- Myth: You need a separate TIN for each job or business you have.
- Fact: Only one TIN is assigned to a taxpayer, whatever the number of jobs or businesses, and a person with a TIN may not apply for another (RR 7-2012). New activities are registered under the same TIN.
- Myth: Your TIN expires after a certain number of years and must be renewed.
- Fact: A TIN does not expire. You keep it for life and update your registration when your circumstances change.
- Myth: You can use your SSS number or PhilHealth ID as your TIN.
- Fact: Your TIN is distinct from SSS, PhilHealth and Pag-IBIG numbers. The BIR requires your TIN on returns and documents filed with it (NIRC Sec. 236).
- Myth: Minimum-wage earners do not need a TIN.
- Fact: Every employee registers with the BIR within 10 days from employment, including minimum wage earners, so the employer can report their pay (NIRC Sec. 236(A)). Minimum wage earners pay no income tax on their statutory minimum wage.
- Myth: Getting a second TIN has no serious consequences.
- Fact: Securing more than one TIN violates BIR regulations and is penalized under the Tax Code (RR 7-2012). If you already have a TIN, update your registration instead.
Questions people ask
What does a Philippine TIN number look like?
A TIN has nine digits, shown here as XXX-XXX-XXX rather than a real taxpayer number. A branch code is entered separately or appended on some forms. Older BIR systems show a three-digit branch code; the current Taxpayer Portal asks for five digits. Copy the TIN and branch code from your registration record and follow the form you are using.
What is the meaning of TIN in BIR records?
TIN means Taxpayer Identification Number. It identifies the taxpayer; the RDO code identifies the Revenue District Office, and a branch code identifies the registered branch. They are different fields.
How do I check if I already have a TIN?
Contact your Revenue District Office or the BIR's contact channels with your full name and date of birth. If you worked before, your former employer likely registered you; ask its HR department. Do not apply for a new TIN if you already have one (RR 7-2012).
Can I register for a TIN online?
Yes. The BIR's Online Registration and Update System (ORUS) handles TIN applications and registration updates, and you can also register at your Revenue District Office.
What if I lost my Certificate of Registration (BIR Form 2303)?
Request a replacement from your Revenue District Office through a registration update. Your TIN itself does not change; only the certificate is reissued.
Do I need a TIN if I earn less than the taxable threshold?
Yes, if you are an employee or engaged in business. Registration is required within 10 days from employment or before starting a business (NIRC Sec. 236(A)). Filing an annual return is a separate question; for example, an individual whose taxable income does not exceed ₱250,000 is not required to file unless engaged in business or a profession (NIRC Sec. 51(A)(2)(a)).
What happens if I don't file a tax return for three years?
Your TIN stays the same, but any returns you were required to file remain due. Ordinary late filing or payment can carry a 25% surcharge and 12% annual interest on unpaid tax. Covered micro and small taxpayers qualify for a 10% surcharge and 6% interest under RR 6-2024. Willful neglect or a false or fraudulent return carries a 50% surcharge; possible compromise penalties are separate.
Can my TIN be transferred to another person?
No. A TIN belongs only to the person or entity to whom it is assigned. When a taxpayer dies, the executor or administrator registers the estate, which receives its own new TIN (NIRC Sec. 236, as amended by RA 11976).
Is my TIN the same as my Certificate of Registration?
No. Your TIN is your identification number. The Certificate of Registration (BIR Form 2303) is issued to registered businesses and professionals and shows the TIN, the registered tax types and the branch.
Do minors need a TIN?
Yes, if they have income or transactions that require filing a return. The TIN is issued in the minor's name, usually with a parent or guardian handling the application, and remains valid into adulthood.
In practice
- Your employer asks for your TIN during onboarding; if you do not have one, register within 10 days from the start of employment.
- Banks and brokers ask for your TIN so they can report income they pay you and the taxes they withhold.
- The BIR matches the compensation and withholding your employer reports, and the payments listed by clients in their withholding returns, against your TIN.
- If you change jobs, your TIN stays the same; give it to your new employer so your income is reported correctly.
- Overseas Filipino Workers with Philippine-source income, such as rent, use their TIN to file returns on that income.
