On 2 October 2017, the Federal Tax Administration (FTA) published a circular concerning interest rates in the area of direct federal tax for the calendar year 2018 and maximum pillar 3a deductions in the 2018 tax year.

The interest rates in the area of direct federal tax for the calendar year 2018 remain unchanged compared to the previous year. The default and refund interest rate remains at 3% and the interest rate for advance payments at 0% (cf. the Ordinance of 10 December 1992 on the Maturity and Interest Maturity of Direct Federal Taxes).

The tax deduction for tied pension provision (pillar 3a) for the 2018 tax year also remains unchanged (maximum deduction for taxpayers with a 2nd pillar CHF 6,768 or for taxpayers without a 2nd pillar CHF 33,840).
