Mistakes SMEs make most often, AHV / AVS Social Insurance
Four issues that authorities flag regularly in audits of small and medium businesses. Most are avoidable with early setup.
Independent contractor status is not your choice
Whether you are 'self-employed' for AHV is decided by the cantonal compensation office, not by your contract. If you work for one or two main clients with set hours, you may be reclassified as an employee and your client billed retroactively for employer contributions plus penalties.
Minimum contribution applies even on zero income
The CHF 514 minimum applies regardless of actual earnings. A freelancer with zero income in a tax year still owes the minimum. Many side-business founders are caught by this in lean years.
Provisional bills are estimates, not final
AHV sends provisional quarterly bills based on prior-year income. If your income rises, the year-end reconciliation may produce a large supplemental bill. Set aside cash for the reconciliation; don't treat the provisional bills as final.
ALV (unemployment) is not available to the self-employed
Sole traders cannot buy into Switzerland's unemployment insurance. If you stop trading, you have no ALV safety net. Plan reserves accordingly, especially if you have employees who depend on the business.
