Audit & Compliance Support in Switzerland (GmbH/AG)

Audit & compliance support is a structured service that helps Swiss companies keep their accounting, tax, VAT, and payroll records review-ready—for statutory audits or reviews, VAT inspections, bank onboarding, investor due diligence, and year-end closings. For a Swiss GmbH/AG, the real goal is simple: no surprises—clean reconciliations, defensible documentation, and controlled processes.

What “audit & compliance” means for a Swiss company

In Switzerland, “audit & compliance” usually covers two layers:

  • Statutory audit / statutory review readiness (ordinary audit, limited statutory examination, or audit opt-out where permitted)

  • Operational compliance readiness for authorities and stakeholders (VAT controls, payroll/social insurance discipline, accounting documentation, and year-end close quality)

A strong setup is built upstream—before the auditor or authority arrives—through a disciplined month-end close, consistent supporting files, and clear governance routines.

Who this service is for

Audit & compliance support is a strong fit if you are:

  • A Swiss GmbH/AG approaching statutory audit thresholds

  • A company transitioning from limited audit to ordinary audit, or planning an opt-out

  • A foreign-owned Swiss subsidiary needing group-quality reporting and documentation

  • A business preparing for bank financing, investor entry, M&A, or restructuring

  • A company with VAT exposure (cross-border flows, frequent credits, or complex rate mapping)

  • A business that has late filings, historic gaps, or messy books and wants a controlled clean-up

Statutory audit landscape: what applies to your GmbH/AG

Swiss companies may be subject to:

  • Ordinary audit

  • Limited statutory examination (often called “limited audit” in practice)

  • Opt-out of limited audit, if conditions are met and properly filed

Ordinary audit thresholds (GmbH/AG)

An ordinary audit is required if, for two consecutive financial years, a company exceeds two of the three thresholds:

  • CHF 20 million balance sheet total

  • CHF 40 million revenue

  • 250 full-time employees

Opting out of the limited audit

If the company does not require an ordinary audit, it may be able to waive the limited audit with:

  • unanimous shareholder consent, and

  • no more than 10 full-time employees on average

Important rule change (from 1 January 2025)

Swiss law reforms ended the ability to opt out retroactively. The opt-out must be filed before the start of the financial year it should apply to (i.e., it applies to future years only).

What our Audit & Compliance Support typically includes

1) Audit readiness and auditor coordination

  • Audit planning support: scope, timeline, and deliverables calendar

  • PBC pack preparation (“Provided By Client” list) with evidence indexing

  • Handling auditor requests efficiently (controlled Q&A, no document chaos)

  • Clean sign-off path with directors/shareholders (minutes, approvals, explanations)

2) Pre-close and year-end close quality control

  • Full balance sheet reconciliation set (cash, receivables, payables, loans, equity)

  • Cut-off testing support (period allocation discipline)

  • Review of one-off transactions and unusual postings

  • Accruals/deferrals discipline and schedule building

  • Consistency checks between bookkeeping, annual accounts, and tax/VAT positions

3) VAT compliance readiness

VAT compliance is often reviewed in practice through reconciliations and documentation integrity. We support:

  • VAT control account discipline and ledger-to-return consistency

  • Annual VAT reconciliation routines and correction workflows where discrepancies are found

  • Preparation for VAT audits/inspections with documentation readiness standards

4) Payroll compliance readiness (finance perspective)

  • Payroll posting discipline and payroll control account reconciliation

  • Social insurance / source tax alignment (inputs and evidence readiness)

  • Year-end payroll file quality control to prevent “last-minute rebuilds”

5) Accounting clean-up and back filings (when needed)

  • Reconstruction of missing periods and correction of classification errors

  • Catch-up reconciliations and restoration of a reliable close routine

  • “Stabilisation plan” so problems do not repeat after clean-up

What “audit-ready” looks like: a practical checklist

A Swiss GmbH/AG is typically audit-ready when:

  • Cash and bank: every account reconciled to statements, with clear outstanding items

  • Receivables & payables: ageing is consistent with the ledger; credit notes and write-offs are documented

  • Loans & intercompany: agreements, schedules, and balances reconcile (no “mystery balances”)

  • Equity movements: resolutions and supporting documentation exist for capital changes/distributions

  • Fixed assets: additions and depreciation logic are supported and consistent

  • VAT: VAT returns reconcile to VAT control accounts; supporting invoices and rules are consistent

  • Close controls: period cut-offs and adjustment logic are applied consistently year-to-year

Typical risks we help you prevent

  • Unreconciled balance sheet items causing audit delays and rework

  • Misclassified shareholder or intercompany transactions creating tax exposure

  • Weak evidence trails (missing contracts, unclear business purpose)

  • VAT returns that do not reconcile to the accounts (high audit/inspection friction)

  • Payroll postings that drift from actual payroll outputs (year-end surprises)

  • Late or incorrect opt-out filings (post-2025 rule change)

Frequently asked questions (FAQ)

1) Do all Swiss companies need an audit?
Not always. Some companies may qualify for opt-out if conditions are met (including ≤10 FTE and unanimous shareholder consent), and the opt-out is filed correctly.

2) When is an ordinary audit mandatory?
If two of three thresholds are exceeded for two consecutive years: CHF 20m assets / CHF 40m revenue / 250 FTE.

3) What changed with opting out from 2025?
Opt-out can no longer be done retroactively; it must be filed before the financial year it applies to.

4) What is the biggest reason audits become expensive?
Poor month-end discipline—missing reconciliations, scattered documentation, and unresolved exceptions that accumulate until year-end.

5) Can you help if our accounting is already “messy”?
Yes. We typically run a controlled clean-up (reconstruct, reconcile, stabilise) and then move into a repeatable compliance routine.

6) How do you support VAT compliance reviews?
Through reconciliations, evidence standards, and a documented annual reconciliation routine that ties VAT reporting to the accounts.

7) Can you coordinate with licensed auditors?
Yes. We prepare the PBC pack, manage timelines, and streamline Q&A so the audit does not disrupt operations.

8) What do you need from us to start?
Your legal form (GmbH/AG), canton, last annual accounts (or trial balance), VAT status, payroll status, and an overview of transaction volume and complexity.
