Why Is The Tax Number Needed?

The tax number is linked with the identity of a person. Identity is essential. It is usually described with multiple associations related to a particular individual.

It can be one’s nationality, ethnicity, profession, education, or even place of birth. Every country has some documentation that is used as a legal document that identifies a person.

Usually, the documentation for verification purposes is referred to as the national identity card in which the social security number is mentioned.

Countries need the individual’s identity for not just verification purposes but also for different procedures like opening a bank account, taxation, or even background checks in criminal proceedings.

A specific number is allotted to every individual on their national identity card that is unique to that particular individual. Some countries use the number allotted to every citizen as the number that lists them as taxpayers.

But there are different proceedings when it comes paying taxes for non-individuals and foreigners.

Let’s look at the article to learn about the allotment procedure of Tax Number and Tax ID!

What Is the Tax Number In Taiwan?

The jurisdiction that allows the Tax Identity Number is the Republic of China (Taiwan).
In Taiwan, the Tax Identification Numbers are, in short, referred to as TIN.

Both individuals and entities are allotted tax numbers in Taiwan. Further categorization has been done in the following manner:

Individuals
⦁ Nationals
⦁ Non-Nationals

Non-individuals
⦁ Business entities

How Are Individuals Assigned Their Tax Numbers In Taiwan?


The Individuals are usually categorized as nationals or non-nationals. The details are given below:

Nationals

Nationals are the people who have applied for or own a household registration in Taiwan.

It can be in the past or continue to do so in the present. Their household registration application verifies that they have a National ID Card Number.

The nationals can then use this National ID card number as a Tax Number.

Non-nationals:

This category involves individuals who have never applied for household registration, people of Hong Kong/ Macau Residents or Mainland China area, and foreigners.

They are assigned either:
⦁ U.I. number (Unified Invoice number)
⦁ Tax Code (Those who don’t acquire a U.I. number)

For Foreign Individuals TIN depends on its documentation and identification. Any individual that has a Chinese ID card for its identification then the card number will be that individual’s identification. It will also be used in any required legal documentation.

Suppose the individual does not have a Chinese ID card and uses a passport or any other documentation that verifies his identity.

In that case, that particular document can be used to present to a local tax office, which can then issue the TIN accordingly.
In some regions, passport numbers can also be used as TIN, especially for foreigners.

When Are The Individuals Not Automatically Issued A TIN?


Individuals are usually issued TIN in Taiwan, automatically. However, there can be a few incidents when the individuals have yet to be issued TIN.

Mostly when people never had any household registrations in Taiwan or needed their national I.D. card.

People who have stayed in Taiwan or the Republic of China for a very short period of time (usually less than 90 days) are also not issued TIN.

However, the accessibility of TIN is no issue, as they can quickly get it themselves.
They can produce the Tax Codes by quickly accessing the coding principles of the Taiwanese Tax authority online.

How Are Non-Individuals/Entities Assigned Their Tax Numbers?

The tax numbers assigned to non-individuals (Business entities and corporations) are known as:


⦁ Business Administration Number (B.A.N.)
⦁ Government Unified Invoice (G.U.I.)

Business Administration Number (B.A.N.)


Generally, the Uniform Social Credit Code is used as the Tax Identity Number of an entity. This number can be found on the entity’s Business Licence.

If there is no Uniform Social Credit Code assigned to the business entity, then the authority of the local tax office assigns its TIN which has 18 digits.

The taxation office assigs TIN according to the relevant rules of the taxation authority. After 2018, the rules have changed. Previously, the 15-digit Taxation Identity Number was used.

Now 18-digit code is used. Due to this transition, some entities might still use the same code printed on their Tax Registration Certificate.


Government Unified Invoice (G.U.I.) / V.A.T. Number IN Taiwan


The business entities must also have a G.U.I., Government Unified Invoice, to record any monetary interaction with other corporations.

A GUI number consists of two letters before any numerical eight digits. The companies are assigned these alphanumeric codes as a range of numbers by the tax authorities of Taiwan.

Corporations and independent business entities must have a G.U.I. number on every document that may track value-added tax (V.A.T.).

So, it will be against the law of Taiwan if every sales invoice, down payment document, debit & credit memo, and purchase or sales return document does not have a G.U.I. number. This act against the law can be a punishable offense.

Also, keeping a record of All interactions through the use of G.U.I. makes the V.A.T. returns easier.

How To Obtain B.A.N.?

A BAN can only be achieved if it has been applied for. Business Registration Act, Company Act, and other similar laws are followed when one initiates a business and wants to register it in Taiwan.

One usually applies for B.A.N. when the business is started. But it may also be applied when the company has to pay or withhold tax under the relevant Taiwanese laws.

Does The Jurisdiction Automatically Issue TINs To All Residents For Tax Purposes?


The jurisdiction only issues TINs automatically to those who use their their Chinese ID card as their main source of identification.

However, the issuance of TIN occurs for the individuals who use their passports for identification, when they pay their first Tax Payment.

Issuances of TINs for entities is a different issue. Entities do no get immediate issuance of Tins rather they have to apply for it first at the National Burau of Taxation.

How Do Entities Apply For A Tax Identification Number In Taiwan?
