Use pension to finance mortgage

[Dr.PI]

@covfefe

If I withdraw second pillar pension to finance mortgage, can my spouse do voluntary buy-in into their second pillar in the following years (without me having paid back money into my second pillar)?

Yes, even the same year.

@covfefe

Which Kanton will deduct taxes if I use my pension to finance mortgage?

The one where you are paying taxes in the year of withdrawal .

@covfefe

Which Kanton will “return” me the tax if I pay that withdrawal (or part of) back to my pension?

That’s a good one! I think the one taxed you originally, irrespectively of your current domicile.
