What is that?
Refers to Swiss nationals: When leaving Switzerland and taking residency in an other country, we register with the local Swiss consulate. It then issues a registration certificate.
Ok so actually having pillar 2 released and liquid is as simple as living 2 years abroad ?
I don’t know about a legal requirement for 2 years abroad, and have known people who withdrew and then returned to CH less than 2 years later and did not have issues, but tax residency rules vary between cantons. The main requirement for early withdrawals (leaving Switzerland permanently) is pretty vague, and leaves a lot of room for interpretation by cantonal tax offices.
AFAIK, you would end up with a gap in your pension fund that you should be able to close by making voluntary contributions. The size of the gap will vary depending on the pension plan.
