Tax Identification Number | TIN

Tax authorities assign a tax identification number (TIN) to every legal entity such as a limited company as well as to every individual citizen subject to taxation. This tax identification number has 9 digits and will not change as long as the company is in existence. In some countries this tax number is also the VAT number at the same time but this is not the case in Austria. The VAT number (value added tax number) is a separate number and starts with “ATU”.
