Step-by-step procedure

Important: distinction between deadline appeal and payment deadline

Appealing does not automatically suspend the obligation to pay. A UTB must, in principle, be paid within 10 days of the date of issue. A request for deferment of payment must therefore be submitted immediately after receipt of the UTB and cannot be postponed until the expiry of the six‑week appeal period.

Step 1 – Receipt and registration of the UTB

Step 2 – Immediate request for deferment of payment

Step 3 – Substantive assessment of the UTB

Step 4 – Filing the administrative appeal

Step 5 – Handling of the appeal

Step 6 – Appeal (if required)
