Contribution base and circular deduction
contribution_base = net_business_income (överskott av näringsverksamhet) Egenavgifter are deductible from income, creating a circular calculation: egenavgifter = net_business_income x rate / (1 + rate) For full rate: effective = 28.97% / 128.97% = ~22.47%.
Apply age reduction
IF born_1938_to_1957: rate = 10.21% ELIF born_before_1938: rate = 0% ELSE: rate = 28.97%
Calculate
egenavgifter = net_business_income x rate / (1 + rate)
F-skatt monthly payments
monthly_F_skatt = (estimated_income_tax + estimated_egenavgifter) / 12
