What You Need to Know
Automatic assignment: No application needed! The Federal Central Tax Office (BZSt) assigns the number automatically—initially to all VAT-liable businesses and small entrepreneurs.
Existing VAT ID gets extended: If you already have a VAT ID (DE + 9 digits), it will be extended by five characters (e.g., DE12345678900001).
For small entrepreneurs: Starting in fall 2025, economically active individuals without VAT liability will also receive the W-IdNr.
Practical tip: Without a tax advisor, you'll need an ELSTER account to receive the number.
The W-IdNr. is intended to simplify dealings with authorities and will gradually replace the current tax number. You have been—or will be—notified as soon as your number is available. We’ll keep you posted!
