Withholding tax in connection with primary, corresponding and secondary adjustments

Transfer pricing adjustments by the Swiss tax authorities may take the form of a primary adjustment by the competent cantonal tax authority and/or a secondary adjustment by the Federal Tax Administration. When a primary adjustment is conducted by a foreign state, a correlative adjustment may be carried out in Switzerland in order to eliminate double taxation. These different adjustments raise a number of issues relating to withholding tax.
