If you leave Switzerland definitively but would still like to have your pension assets paid out, withholding taxes apply.
The Secretariat of the Alvoso Pension Fund is located in Schlieren (Canton of Zurich). For this reason, the tax rates of the Canton of Zurich are applied.
The insurance certificate shows the amount that can still be purchased (purchasing potential). The purchasing potential indicates the maximum amount that you can pay into the pension fund voluntarily, in order to top up the regulatory retirement benefit. Voluntary purchase closes any gaps in your pension provision, increases your retirement pension and also saves taxes.
