What is a tax identification number (TIN)?
The tax identification number is a unique identification number used by tax authorities to identify taxpayers and facilitate the administration of their tax affairs. For most EU countries, the TIN is the personal number on the ID or the passport - the European Commission has summarized detailed description about the format of TIN for each respective country here.
To enter or update the TIN in your TWINO profile, go to “My Profile” section and select “Tax Details”, and enter your TIN in the “Tax identification number” field.
