The BVG minimum retirement assets (compulsory part of your termination benefit) are not paid out in cash, but are kept in Switzerland until the insured person can use them at retirement age. The insured person can only receive this retirement capital in cash if he is not subject to the pension scheme (social security) of the new country of residence.
However, the insured person receives the amounts contributed to the excess portion of the termination benefit, i.e. the benefits paid out above the statutory BVG contribution portion.
Yearly taxes depends on your location. Compare between canton and cities.
