Tax registration number

Requirement

All companies are given an identification number, named organization number, by authorities. This number is used when reporting corporate information to the government.

All countries that have VAT as a method of taxation require a VAT registration number. This number is often the organization number, with the addition of the country code.

In Taiwan, the VAT registration number is a unique number. This number is the organization number, prefixed with the country code, in this format: TW XXXXXXXXX-X. The last digit in the organization number is a modulo 10 number.

M3 solution

The organization number, tax number, and VAT number of the company are stored on the division. The VAT numbers of the company’s customers and suppliers are stored per customer and supplier. The VAT number can be validated by M3. Validation rules are based on Modulo 10 or 97, depending on the type of number and country.
