Questione giuridica chiave
Whether default interest of CHF 149.25 on overdue AHV contributions for 2013 had to be waived because the contribution assessment was issued late and the tax office allegedly transmitted the income data earlier.
Decisione estratta
Default interest remained due. It is a statutory compensatory payment independent of fault, so any delay attributable to the compensation fund or the tax office does not remove the interest obligation.
Motivazione estratta
Art. 26 ATSG and Art. 41bis AHVV make default interest mandatory once the statutory conditions are met. The interest is not punitive and does not depend on who caused the delay in assessment or payment.
