The Federal Department of Finance (FDF) has decided that for the calendar year 2018 it will continue not to pay any refund interest on amounts of direct federal tax paid early. The default and refund interest rate remains unchanged.
Interest rates remain at a historically low level. The FDF has therefore decided to leave the remuneration interest rate at 0%. The default / refund interest rate also remains unchanged at 3%.
The interest rates are specified in the appendix to the FDF Ordinance on the Maturity and Interest Rates of Direct Federal Taxes. If the interest rates recover, the remuneration interest rate is to be raised again.
