We are centralizing and simplifying for you - from 02.01.2026, there will only be one joint service center (ZIA) for the tax offices Stuttgart I, II and III, which you will find at the tax office Stuttgart I.
The ZIA (Zentrale Informations- und Annahmestelle) in the STU II and III tax offices will be closed accordingly on 30.12.2025 and will no longer be available to you from 31.12.2025. This will make things easier for you as a taxpayer from 02.01.2026: One central point of contact at the tax office Stuttgart I.
