Section 5 -- Computation steps
Step 5.1 -- 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%.
Step 5.2 -- Apply age reduction
IF born_1938_to_1957: rate = 10.21%
ELIF born_before_1938: rate = 0%
ELSE: rate = 28.97%
Step 5.3 -- Calculate
egenavgifter = net_business_income x rate / (1 + rate)
Step 5.4 -- F-skatt monthly payments
monthly_F_skatt = (estimated_income_tax + estimated_egenavgifter) / 12
Section 6 -- Payment schedule and tax deductibility
Payment schedule
| Payment | Due date |
|---|---|
| Monthly F-skatt | 12th of each month (17th for Feb/Aug) |
| Annual reconciliation | Inkomstdeklaration by 2 May |
Client can request jämkning if income changes significantly.

| Question | Answer |
|---|---|
