I've received Status S residence permit and keep working for a Ukrainian company.
According to SEM, this is considered a home office job and the government doesn't mind if I'm hired by Ukraine. At the same time, I realize the question of taxes is still in the air and I need to figure it out before the 183 days end and I become a tax resident.
I would really appreciate your help!
You also need to account for social contributions.
Search this forum for ANOBAG - the question has been asked many times. It is not specific to Ukraine or S-permits.
On a related topic, individuals with S status who are employees of Swiss companies would be subject to Quellensteuer, according to the Arbeitgeber Banken website (translated):
"Social insurances and taxes: The usual social insurance contributions must also be paid for employees with protection status S (AHV, IV, EO, UVG, PK). With regard to withholding tax, it is advisable - depending on the family situation of the person - to clarify with the cantonal tax authorities the applicable rate."
"Do I have to pay taxes in Switzerland if I continue to work remotely for a Ukrainian employer?
Yes, in principle this is regulated by the applicable double taxation agreement between Switzerland and Ukraine. You must report to the tax office here and fill out a tax return. If Ukrainian taxes have already been deducted from your salary, you could in principle request a refund there - but it remains to be seen whether this will work in practice."
