What is a Tax Identification Number (TIN) in Singapore?

Are you trying to find out what a Tax Identification Number (TIN) is in Singapore? You are in the right place. Both individuals and businesses require a TIN to adhere to tax regulations and ensure smooth financial transactions. This brief guide will clarify what a Singapore tax identification number is, why it is required by the Inland Revenue Authority, how to locate your TIN, and how it functions in your tax matters.

In Singapore, the Tax Identification Number (TIN) is a unique code consisting of nine to ten digits issued by the government to both individuals and organisations responsible for paying taxes. It plays a key role in ensuring legal compliance with tax regulations, simplifying record-keeping, and facilitating efficient tax filings. Whether you're a Singaporean citizen, permanent resident, or business entity, you are assigned a distinct tax identification number that helps streamline tax monitoring and quickly identify any discrepancies.

At its core, the TIN is essential for tax-related matters, aiding in smoother tax compliance and administrative tasks.

In Singapore, the Inland Revenue Authority of Singapore (IRAS) plays a central role in all tax-related activities, acting as the government body in charge of tax administration. IRAS is the official authority that issues Tax Identification Numbers (TINs) in the country. For Singaporean citizens and permanent residents, this TIN is known as the Tax Reference Number (TRN), allocated by IRAS.

What is a Tax Reference Number (TRN)?

In Singapore, a Tax Reference Number (TRN) is a unique identifier used for tax-related purposes. It is issued by the Inland Revenue Authority of Singapore (IRAS) to identify taxpayers in the country. The TRN is essential for filing taxes, making payments, and managing other tax obligations.

• For Singapore citizens and permanent residents, the TRN is typically their National Registration Identity Card (NRIC) number.
• For foreign individuals who do not have an NRIC, the TRN is often their Foreign Identification Number (FIN).
• For business entities, the TRN is referred to as the Unique Entity Number (UEN).

Each TRN serves as a distinctive code, allowing for efficient and accurate tax administration.

In Singapore, the Tax Identification Number (TIN) varies depending on whether the individual is a Singapore citizen, permanent resident, or foreigner. Here’s how they are differentiated:

For Singapore Citizens and Permanent Residents:

• The National Registration Identity Card (NRIC) number serves as their TIN.
• The NRIC is a 9-character alphanumeric code (e.g., S1234567A) issued by the Singapore government.
• Format: Starts with "S" or "T," followed by 7 digits and a letter.

For Foreign Individuals (Non-residents):

• The Foreign Identification Number (FIN) serves as their TIN.
• The FIN is also a 9-character alphanumeric code (e.g., G1234567L) assigned to foreigners working or residing in Singapore.
• Format: Starts with "F" or "G," followed by 7 digits and a letter.

Both NRIC and FIN numbers uniquely identify individuals for tax purposes and are used in tax filings, communications with the Inland Revenue Authority of Singapore (IRAS), and other financial transactions.

In Singapore, the Tax Identification Number (TIN) for business entities is referred to as the Unique Entity Number (UEN). The UEN is a distinct identifier issued by government authorities to different types of business entities for tax and other regulatory purposes. Here's how the UEN varies across different entities:

For Companies (e.g., Private Limited, Public Companies):

• Issued by the Accounting and Corporate Regulatory Authority (ACRA) upon company incorporation.
• The UEN typically starts with the year of registration/year of issuance (e.g., 201234567A).

For Limited Liability Partnerships (LLP) and Limited Partnerships (LP):

• Also issued by ACRA, and similarly follows the format starting with the registration year (e.g., 201876543Z).

For Sole Proprietorships, Partnerships, and Other Businesses:

• These businesses also receive a UEN issued by ACRA or relevant authorities, following a similar format.

For Entities Registered with Other Authorities (e.g., Societies, Trade Unions):

• UEN is issued by specific agencies (such as the Registry of Societies), but the format may vary depending on the registering body.
• Example: Societies might have UENs that start with a letter, followed by digits (e.g., S89SS0012K).

For Individuals

In Singapore, individuals are automatically assigned a Tax Identification Number (TIN) when they become eligible taxpayers. The process differs slightly depending on whether the person is a Singapore citizen, permanent resident, or foreign individual:

For Singapore Citizens and Permanent Residents:

• The National Registration Identity Card (NRIC) number, which is assigned at birth or upon receiving permanent residency, serves as the TIN.
• You don’t need to apply separately for a TIN if you are a citizen or permanent resident, as your NRIC number is automatically used by the Inland Revenue Authority of Singapore (IRAS) for tax purposes.
• For NRIC holders (citizens and PRs): Your TIN is your NRIC number, which can be found on your identification card.

For Foreign Individuals (Non-residents):

• Foreigners working or living in Singapore are assigned a Foreign Identification Number (FIN), which serves as their TIN.
• The FIN is typically issued when you are granted a work pass, employment permit, or residency status in Singapore by the Ministry of Manpower (MOM) or Immigration and Checkpoints Authority (ICA).
• Once issued, your FIN will automatically be recognized as your TIN for tax-related matters with IRAS.
• For FIN holders (foreign individuals): Your TIN is your FIN, which can be found on your work pass, employment card, or immigration documents.

You don’t need to apply for a separate TIN in Singapore, as the relevant authorities issue it automatically based on your residency or employment status. You can also check your TIN on Singpass.
