The tarjeta de indentidad de extranjero (TIE) is a kind of identification that displays your NIE number, address, and places of employment and education. You can’t receive a TIE card if you don’t have an NIE number. It serves as documentation for authorization to live or stay in Spain for a specific period.
The card must be obtained by appointment at your neighbourhood police station or foreigner’s office, just like the NIE number. However, you can renew your TIE card if you wish to. As a Spanish resident, you are required to declare your global income to the Spanish authorities, regardless of which country it came from.
