Opting-out of audit in Switzerland (2026): legal requirements, risks and checklist for SME managers

You have an AG or GmbH in Geneva, and someone suggested: "We could do an opting-out, it saves us the audit." Yes, sometimes it's a good decision. Sometimes, it's a classic trap.

The topic is less “legal” than it seems. The real question is: can your company do without a limited audit without shooting itself in the foot (bank, investors, governance, tax, credibility)?

I explain the requirements, procedure, documents, and practical risks we see in Geneva, and leave you with a ready-to-use checklist.

Legal requirements for opting-out: who is eligible and when? (AG, GmbH, thresholds, timing, new rules 2025-2026)

Opting-out: what exactly are we talking about?

In Switzerland, an AG or GmbH is generally required to undergo an audit (at least a limited audit), unless it meets the conditions to waive it. This waiver is called opting-out.

It is a waiver of the limited audit, not just an “administrative box” to tick randomly.

Legal basis: Swiss Code of Obligations, art. 727a et seq. (source: Swiss Code of Obligations (art. 727a et seq.)).

Condition #1: fewer than 10 full-time jobs on average per year

The recurring criterion: fewer than 10 full-time jobs (FTE) on average per year.

Two common pitfalls:

• It’s about full-time jobs, not “number of people”. 18 people at 40% may still be under 10 FTE.
• It’s an annual average. If you grew during the year, calculate properly.

In practice, many Geneva SMEs discover the issue at year-end: they hired 2 people in September, and no one recalculated the FTE. Result? Opting-out was filed when it was no longer allowed. And at the commercial register, that rarely ends well.

Condition #2: unanimous agreement of shareholders/partners

To waive the audit, you need the agreement of all shareholders (AG) or partners (GmbH).

Unanimity. Not “comfortable majority”. Not “they won’t object”. Unanimity.

Typical case: a GmbH with 3 partners, one minority at 10% who never responds. Without their formal agreement, you don’t have opting-out.

Condition #3: not subject to ordinary audit

If your company meets the criteria for ordinary audit (size, listing, etc.), opting-out is not an option.

Even if you are “small” in staff, some cases require a heavier audit. If in doubt, check this first, or you’ll waste time.

When can you request opting-out? Practical timing

You can:

• request opting-out from incorporation (if conditions are met),
• or decide later, at a general meeting (AG) or partners’ decision (GmbH).

Practical timing:

• If you want to avoid appointing an auditor for the upcoming fiscal year, the decision and filing with the commercial register must be done properly and early enough.
• If you already have an auditor, opting-out doesn’t “magically erase” what’s been done. Manage the transition.

New rules 2025-2026: what to watch for

Commercial registers have strengthened standardization of documents (standard declarations, date consistency, signatures). For 2025-2026, we mainly see:

• stricter requirements for the KMU declaration (often called KMU-Erklärung),
• refusals when the minutes are too vague (“we waive the audit” without mentioning unanimity, FTE, relevant fiscal year),
• requests for additional documents when the company has recent shareholding changes and the list of beneficiaries is unclear.

For practical details, cantonal guides are useful (source: Merkblatt Opting-out – Commercial Register Bern; source: Guide of the Commercial Register Zurich: opting-out procedure). Even if you’re in Geneva, it shows the expected standard.

Procedure and documentation: how to decide and declare opting-out (minutes, shareholder/partner declarations, filing with Commercial Register, documents to keep)

Step 1: check the requirements (and document them)

Before drafting anything:

• calculate annual average FTE (with a simple spreadsheet, but keep it),
• check shareholding/partners: who must sign, who has voting rights,
• confirm you’re not under ordinary audit.

This isn’t a luxury. It’s your defense file if someone ever challenges it.

Step 2: formal decision (minutes) — AG vs GmbH

AG: decision of the general meeting (GM). The minutes must be clear: date, quorum, unanimity, explicit mention of waiver of limited audit.

GmbH: decision of the partners (often in a partners’ meeting). Same logic.

What the minutes must state clearly:

• that the company meets the fewer than 10 FTE on annual average condition,
• that all shareholders/partners consent,
• from which fiscal year the waiver applies,
• that the audit body (if it existed) is deregistered.

Step 3: declarations to attach (KMU-Erklärung and consents)

According to practice, you’ll be asked for:

• a KMU declaration (KMU-Erklärung) confirming the requirements,
• consents from shareholders/partners (often included in the minutes if everyone signs, otherwise separate),
• sometimes confirmation of staff numbers.

Beware, it’s a classic trap: minutes signed only by the president, without proof of unanimity, and you get a refusal.

Step 4: filing with the Commercial Register

Filing is done with the competent commercial register (in Geneva for a Geneva company). The register checks the form, not your accounting. But it checks very thoroughly:

• date consistency,
• signatures,
• wording,
• presence of documents.

If you have a “dynamic” structure (entries/exits of partners, share transfers, directors abroad), anticipate: the register will request additional documents.

Step 5: documents to keep (your shield)

Even if the register accepts, keep a complete file:

• FTE calculation (with HR supporting documents if possible),
• original signed minutes,
• KMU declarations,
• list of shareholders/partners at the time of decision,
• correspondence with the register.

Why? Because the risk isn’t just “administrative”. The risk is a shareholder dispute, a sale, a bank request, or a tax audit where you’re asked: “On what basis did you waive the audit?”

What opting-out really changes in your daily life (accounting, closing, responsibilities)

Sometimes you hear: “Without an auditor, we can do whatever we want.” No.

Your accounting obligations remain the same

You must still:

• keep proper accounts,
• prepare annual financial statements,
• comply with presentation rules,
• keep documents.

The difference is that there’s no longer an independent third party “stamping” the closing.

Directors/managers’ liability becomes more exposed

Without limited audit, errors remain unnoticed longer. And when they surface, it’s bad.

Examples we see:

• forgotten provisions,
• overvalued client receivables,
• lingering private expenses,
• VAT mishandled (and the Swiss tax authority doesn’t joke about that).

Quick VAT reminder (useful because it comes up often): standard rate 8.1%, reduced rate 2.6%, special accommodation rate 3.8%.

Risks of opting-out: access to credit, bank expectations, investors, shareholders, possible reversal

Bank: the “yes” in principle, then the list of conditions

In Geneva, many SMEs opt-out… then request a credit line 6 months later.

Common bank reaction:

• “OK, but give us accounts signed by a fiduciary”
• or “OK, but we want quarterly reporting”
• or “OK, but we increase guarantees”

Result? You save the audit, then pay for reporting and credibility elsewhere.

In our opinion, if you have:

• dependence on bank financing,
• covenants,
• an acquisition project,

… opting-out should be discussed with the bank beforehand. Not after.

Investors and minority shareholders: trust isn’t automatic

Without an auditor, a minority may feel “blind”. And an external investor will ask for:

• audited accounts,
• or at least an independent review.

You may end up doing a “voluntary” audit at the worst moment (fundraising, sale, partner entry).

Governance risk: when no one challenges the numbers

Field anecdote: a Geneva service SME, opting-out for 3 years. Everything looked fine “on paper”. During a sale discussion, the buyer requests due diligence. We discover:

• wrongly capitalized expenses,
• overstated margin,
• poorly allocated social debts.

The deal doesn’t fall through, but the price drops. And the audit savings over 3 years seem… modest.

Reversal: possible, but not always comfortable

Yes, you can return to limited audit:

• if you exceed 10 FTE,
• if a shareholder/partner requests it (according to applicable rules),
• if you want to reassure a bank or prepare a sale.

The problem is timing: returning to audit when under pressure (growth, financing, conflict) costs more and takes longer.

Table 1 — Opting-out or limited audit: concrete comparison for a Geneva SME

Step-by-step: decide properly (without being rejected by the register or the bank)

1. Calculate FTE over 12 months (average). Document it.

2. Map shareholding/partners: who must consent, who signs, who has voting rights.

3. Ask the tough question: “Will we need a bank, leasing, investor in the next 12-24 months?”

4. Choose the effective date (relevant fiscal year). Avoid mid-year changes if possible.

5. Draft clear minutes (AG GM / GmbH partners’ decision) with:

• unanimity,
• FTE mention,
• waiver of limited audit,
• deregistration of the audit body.

6. Prepare the KMU declaration and consents if needed.

7. File with the commercial register with a complete dossier.

8. Set up a mini internal control system (even simple): payment separation, invoice validation, monthly bank reconciliations.

9. Inform your bank if you have existing lines. Better a short discussion now than a blockage later.

10. Archive the file (paper + digital) with clear logic.

Checklist: key steps and documents to gather before deciding on opting-out (resolution template, KMU-Erklärung, deadlines, supporting documents)

Checklist 1 — Decision and “commercial register” documents

• Dated and signed annual average FTE calculation (internal or fiduciary)
• List of shareholders (AG) / partners (GmbH) at the date of decision
• GM minutes (AG) or partners’ decision (GmbH) mentioning:
• unanimity
• fewer than 10 FTE
• relevant fiscal year
• deregistration of the audit body
• Completed and signed KMU declaration (KMU-Erklärung)
• Individual consents if not everyone signs the minutes
• Compliant signature documents (as per your situation)
• File ready for commercial register filing

Checklist 2 — “Business reality” (what you regret when it’s too late)

• Bank informed (if credit, leasing, guarantees)
• Covenants reviewed (some contracts require audited accounts)
• Minority shareholders aligned (otherwise, conflict ahead)
• Strengthened closing process (VAT, cut-off, provisions)
• Growth plan: risk of exceeding 10 FTE in the year
• Sale/investor entry plan: likely need for reviewed accounts

3 costly mistakes for Geneva AG/GmbH (and how to fix them)

Mistake 1: confusing “fewer than 10 people” and “fewer than 10 FTE”

Symptom: you count employees, not activity rates.

Fix: calculate FTE over the year. Keep details (contracts, rates, periods). If you’re at 9.8 FTE, don’t play clever: monitor monthly.

Mistake 2: lightweight minutes, unanimity not proven

Symptom: standard minutes, signed by one person, no explicit mention of everyone’s agreement.

Fix: clear minutes + signatures or separate consents. The register wants concrete proof.

Mistake 3: opting-out decided… then credit request

Symptom: the bank requests “reviewed” accounts or extra guarantees.

Fix: discuss with the bank beforehand. If you know you’ll finance growth, keep limited audit or prepare solid reporting.

Practical case (CHF): a Geneva GmbH services company hesitating

Let’s take a GmbH in Geneva, digital agency.

• 1 manager at 100%
• 6 employees at 80%
• 4 employees at 50%

FTE calculation:

• 1 × 1.0 = 1.0
• 6 × 0.8 = 4.8
• 4 × 0.5 = 2.0

Total = 7.8 FTE. FTE condition OK.

Shareholding:

• Partner A: 60%
• Partner B: 30%
• Partner C: 10% (inactive, responds late)

The company wants to save the audit and announces a “gain” budget of CHF 4,500 per year (typical audit fees for a small structure).

Except:

• It wants a credit line of CHF 150,000 to smooth cash flow (clients pay in 60 days).
• The bank requests annual accounts “reviewed by a professional” and semi-annual reporting.

Realistic induced costs:

• Strengthened fiduciary review of closing (without legal audit): CHF 2,800
• Semi-annual reporting (2 times): 2 × CHF 1,200 = CHF 2,400

Total “credibility compensation” costs = CHF 5,200.

Result? Opting-out saves CHF 4,500, but triggers CHF 5,200 of work requested by the bank. And you still have the pressure to produce clean figures.

Reasonable decision in this case: either keep limited audit, or negotiate with the bank in advance with a solid file (and accept that savings are not automatic).

What Ark Fiduciaire implements when an SME opts-out (without overcomplicating things)

Without an auditor, you need minimum safeguards. Not an “ISO system”. Just good habits.

Simple but non-negotiable controls

• Monthly bank reconciliation (not just “when there’s time”)
• Two-level payment validation above a threshold (e.g. CHF 5,000)
• Quarterly VAT review (rates 8.1%, 2.6%, 3.8% as applicable)
• Year-end cut-off: invoices to receive, income to receive, provisions

Closing discipline

We often see companies in opting-out closing “by feel”. Until:

• a partner wants to exit,
• a bank requests figures,
• the tax authority checks VAT.

Then, it’s a rush.

FAQ – Can you change your mind? Is opting-out reversible? What are the most common mistakes? Does opting-out have hidden costs?

1) Can you opt-out from the creation of an AG or GmbH?

Yes, if you meet the requirements (fewer than 10 FTE on annual average, unanimity, not under ordinary audit). You must especially prepare the documents correctly from the start (source: official FAQs on audit in Switzerland).

2) Is opting-out reversible?

Yes. You can return to limited audit, and must do so if you exceed the requirements (e.g. staff numbers). The sensitive point is timing: returning under pressure costs more and creates delays.

3) Can a minority shareholder block opting-out?

Yes, because unanimity is required. A minority at 1% can say no. It’s frustrating, but that’s the rule.

4) What are the most common mistakes?

The three we see most:

• wrong FTE calculation,
• poorly documented unanimity,
• opting-out decided without talking to the bank when financing is planned.

5) Does opting-out have hidden costs?

Often, yes. Not a “legal cost”, but a business cost: reporting required by the bank, strengthened review by the fiduciary, heavier due diligence during a sale, tensions with a minority.

6) Can the commercial register refuse the file?

Yes, if documents are incomplete or inconsistent (minutes too vague, missing KMU declaration, signatures, dates). Practice guides give a good idea of the expected standard (source: Merkblatt Opting-out – Commercial Register Bern; source: Guide of the Commercial Register Zurich: opting-out procedure).
