With the adoption of the tax reform and AHV financing (STAF), AHV salary contributions will be adjusted on January 1, 2020 for the first time since 1975. The AHV contribution rate will rise from 8.4% to 8.7%. The total AHV/IV/EO contribution rate will therefore rise from 10.25% to 10.55%. Employers and employees will each pay 5.275% of this total contribution. The net salary paid to employees will therefore be reduced by 0.15 percent.
