Tax on withdrawal of AHV + 2nd Pillar- freizugikeitskonto

Hi all,

As i ( Non-EU) am moving out of Switzerland, i plan to withdraw the AHV and the 2nd Pillar contribution. I heard that to reduce the tax on withdrawal,we can move the money to a "freizugikeitskonto" in Schwyz canton which has the lowset rate of such tax and then move the money to my native country.

Does anyone have more insight into this process and know whether this actually works?

Thanks in advance for your inputs.
Regards
