Kernrechtsfrage
Whether VAT default interest is subject to a limitation period and, if so, which one applies by analogy.
Extrahierter Entscheid
The limitation period for default interest follows the five-year period applicable to the principal VAT claim by analogy, including the statutory rules on interruption and suspension.
Extrahierte Begründung
The statute contains a true gap on default-interest limitation. Because the legislature expressly set a five-year limitation period for the main tax debt and default interest is closely linked to that debt, the same period applies; a shorter civil-law period would be systemically inconsistent and impractical.
