Have you spent an extended period of time working abroad? Did you have an accident and receive daily sickness benefits? Perhaps you did not pay any contributions during your time at university. In these cases, you may have gaps in your AHV/IV contributions. And that is annoying, because it means that your AHV pension will be reduced – by at least 2.3 percent for each missing contribution year.
Apply in writing or online for an AHV statement – known as a statement of individual account – from your AHV compensation fund and see if you have any such gaps. If you notice unjustified contribution gaps, you can request a correction within 30 days.
If you actually do have AHV contribution gaps, you can close them simply by paying the missing AHV/IV contributions retroactively. However, this is only possible for five years after the year of the missing contributions and if you were insured in Switzerland at the time.
If you have contribution gaps because your employer has not paid the contributions, your salary statements will enable you to prove that you worked during the period in question and that your AHV contributions were deducted from your salary. In this case, the relevant contributions will be credited.
