Overview of the Singapore Tax Identification Number

What does the Singapore Tax Identification Number (TIN) signify, and how important is it to your business? To begin with, TIN is an essential identifier for tax-related purposes, issued by the relevant authority to individuals, businesses, and other entities operating within Singapore.

Through this unique number, you can identify yourself with government agencies, primarily the Inland Revenue Authority of Singapore (IRAS), during tax compliance processes (e.g. Goods & Services Tax registration).

Furthermore, this string of numbers serves several practical purposes. It may also be required when applying for export or import permits, remitting CPF payments as an employer, or engaging in financial transactions that involve tax-related considerations.

In other words, the TIN empowers the government to manage tax-related matters efficiently. By assigning a TIN to the subjects, the authority can monitor taxpayer activities and promptly identify discrepancies or irregularities. This allows for streamlined tax administration and facilitates targeted audits when necessary.

Different types of Tax Identification Number

In the case of Singapore, the government has offered various Tax Identification Number types, tailored to meet the specific needs of different individuals and businesses.

With that in mind, let’s delve into the main types of TINs and their features.

TINs for individuals

Each individual in Singapore is assigned to a specific TIN, depending on his/her residency status.

For Singapore citizens and Permanent Residents

Singapore citizens and permanent residents are identified by the National Registration Identity Card (NRIC) number, assigned to them upon birth or becoming a permanent resident.

The NRIC consists of personal information such as a unique ID number, name, birth date, and nationality, and remains consistent throughout their lives. Among these details, the NRIC number is considered your TIN, or more commonly known as the Tax Reference Number (TRN) in Singapore.

Apart from ensuring the filing of personal income tax returns, this number is used for a variety of essential transactions. This includes opening bank accounts, applying for loans, credit cards, or fulfillment of employment requirements, etc.

For foreign individuals residing in Singapore with a work pass

While Singapore citizens and Permanent Residents use the identity number as TIN, a foreigner residing in Singapore uses a Foreign Identification Number (FIN) instead.

These individuals must hold a valid work permit or work pass (e.g. Employment Pass, Immigration Pass) to prove their commitment to the country and be eligible for a FIN. By tracking the FIN code, the government can manage and make sure taxpayers fulfill their obligations properly while living and working in Singapore.

TINs for business entities

In the case of businesses, companies, and other Singapore entities, the primary TIN is regarded as the Unique Entity Number (UEN).

As of January 2009, the UEN has replaced the older Tax Reference Number (TRN) system as the primary tax identifier. The number is, in most cases, issued upon registration or incorporation by the Accounting and Corporate Regulatory Authority of Singapore (ACRA).

During tax-related procedures, your assigned number will act as the business’s identification. Its importance is further demonstrated by its role in engaging with government agencies, financial institutions, and other stakeholders.

In Singapore, the UEN is associated with several entity ID types. These numbers are used to differentiate between businesses, local companies, and other structures such as non-profit organizations, societies, and associations.

The structure of a Tax Identification Number

Identification numbers in Singapore are available in diverse formats, each with its own specific meaning and purpose. Let’s familiarize ourselves with the structure of your TIN to better understand how it is used for business and compliance procedures.

Individual TIN structure

In the case of individuals, the TIN, either the National Registration Identity Card (NRIC) number or the Foreign Identification Number (FIN), shares a common structure.

They typically follow the format: #0000000@, in which:

• # can be “S”, “T”, “F”, “G”, or “M” depending on the status of the holder;
• 0000000 is a 7-digit serial number assigned to the document holder;
• @ is a checksum alphabet.

You can refer to more detailed information on the TIN’s components of an individual here.

Entity TIN structure

UENs differ from individual TINs, which are linked to personal identification documents.

Although the exact structure may vary, the general alphanumeric 9-to-10-character format of your UEN shall depend on the following factors: the issuing agency, the entity type, and the year when the UEN was issued.

What do these characters and numbers signify? To help you navigate, here is an informative table explaining each of their meanings:

Character	Meaning
D	space
C	check alphabet
N	numeric
YYYY	year
TYY and SYY	the year of issuance: T represents “20” S represents “19”
PQ (For UEN – Others)	the entity type (e.g. “LL” for limited liability partnership)

Keep in mind that the identification numbers should not be left blank and should have no preceding spaces. Additionally, the characters highlighted in bold represent fixed prefixes.

Obtaining your Tax Identification Number in Singapore

Now that you have gained a solid understanding of the TIN structure and its importance, it’s time to explore the process of acquiring your identifier. Upholding your tax responsibilities begins with this step.

With that being said, we will be providing a brief but concise overview of the procedures you might encounter.

The process for individuals

Singaporeans (Singapore Citizens and permanent residents)

As a citizen or permanent resident, you will be automatically assigned a TIN based on your National Registration Identity Card (NRIC) number. There is no separate application required for the TIN in this case.

Foreigners holding a valid work pass

To apply for a valid TIN, you will need to register a Unique Account with the IRAS through their online portal or sign up using your SingPass account, then submit an application with your Foreign Identification Number (FIN).

Once you have submitted your application, IRAS will review the information provided and make sure everything is in place. Typically, you can anticipate receiving your TIN, or Tax Reference Number, within 5 working days after that.

The process for businesses

If your business is not yet registered and you do not have a Unique Entity Number (UEN), the next phase is to incorporate your business in Singapore by registering with the ACRA.

Company incorporation is a pivotal step in establishing your business entity’s presence, so engaging a legal expert is crucial.

Here’s what you will need to consider during this procedure:

• Choose a business entity
• Register your company with the ACRA
• Decided whether you want the normal UEN or a special one
• Check your UEN after successfully obtaining it

Once your company’s registration is completed, the ACRA shall issue the Certificate of Incorporation.

The UEN, which typically corresponds to your ACRA Registration Number, will be prominently printed on this certificate. Unlike certain documents that require periodic renewal, your UEN is permanent.
