Watch Out

Mistakes SMEs make most often, Annual Compliance Obligations

Four issues that authorities flag regularly in audits of small and medium businesses. Most are avoidable with early setup.

Late annual filing triggers cascading penalties

Missed Jahresabschluss approval delays the corporate tax return, the AHV final settlement, and dividend distribution. The downstream penalties compound and the cantonal tax office may issue an estimated assessment that overstates your liability. Plan the audit + AGM at least 90 days before the deadline.

Audit thresholds catch growing SMEs

An SME exceeding two of three thresholds (CHF 20M assets, CHF 40M revenue, 250 FTE) in two consecutive years becomes subject to ordinary audit. The transition adds CHF 15K to CHF 40K in audit fees plus a longer close cycle. Track your thresholds quarterly, not annually.

Tax extensions are routine, but request early

Most cantons grant a tax-return extension on request, usually to 30 November or 31 December. The request must be filed before the original deadline (30 September). Late requests are rejected and trigger interest from the original due date.

AGM and audit timing must align

The auditor's report must be issued before the AGM approves accounts. Booking the AGM date before the audit is finished forces a postponement, which can delay dividend distribution and corporate tax filing. Align auditor and AGM calendars in Q1.
