Financial Audit in 2026: Thresholds, Engagements and Choosing an Auditor (FR/BE/CH/UAE)

Financial Audit in 2026: Thresholds, Engagements and Choosing an Auditor (FR/BE/CH/UAE)

The 30-second version

A financial audit can be statutory (mandatory above certain thresholds) or contractual (voluntary, to reassure an investor, prepare a disposal or validate an acquisition). The thresholds vary widely by jurisdiction: €5M balance sheet / €10M turnover / 50 employees in France, €6M / €11.25M / 50 FTE in Belgium, CHF 20M / CHF 40M / 250 FTE in Switzerland for the ordinary audit, and a near-systematic audit in the UAE for LLCs and most Free Zone Establishments. Fees typically range from CHF 3,000 (Swiss limited audit) to AED 100,000 (UAE mid-cap), depending on scope. The choice of auditor depends less on the size of the firm than on its sector specialisation and its ability to engage with your management. On CryviTis, you can identify verified auditors across our four reference jurisdictions.

Why the financial audit became strategic in 2026

For a long time, the financial audit suffered from a purely burdensome image: a legal formality, a cost to bear, a mandatory annual visit. That view is no longer tenable in 2026.

Three developments have profoundly changed the picture:

1. The tightening of financial-transparency requirements. Whether under the European directives (CSRD for large companies since 2024), the UAE Corporate Tax (in force for financial years beginning on or after 1 June 2023) or anti-money-laundering rules, regulatory pressure is pushing companies to be able to justify their accounts beyond the narrow circle of their tax advisor.

2. The sophistication of financing. A fundraising, a structured bank loan, an external-growth transaction or a disposal almost always requires audited accounts. Institutional investors no longer read unaudited balance sheets above a certain ticket size.

3. The spread of international standards. IFRS for large companies, ISA standards (International Standards on Auditing) for auditors: a director wanting to grow their business beyond national borders must understand the mechanics of the audit, if only to anticipate the expectations of their future counterparts.

The financial audit is therefore no longer just an obligation to minimise. It has become a lever of credibility whose mastery distinguishes a seasoned director from one who merely endures their obligations.

📖 Going further: Choosing an Accountant in 2026 — accountancy and audit are two distinct engagements that are often confused. This guide clarifies the line between them.

Statutory audit or contractual audit: the fundamental distinction

First of all, it's important to distinguish between two families of audit that share a common methodology but serve very different purposes.

The statutory audit

The statutory audit is imposed by law when a company exceeds certain thresholds or operates in a regulated sector (banking, insurance, mutual insurance, associations receiving public funds).

In France, this is the statutory auditor's engagement (commissaire aux comptes).

In Belgium, the company auditor's engagement (réviseur d'entreprises).

In Switzerland, the ordinary audit or limited audit depending on the thresholds. In the UAE, a statutory audit performed by an accredited firm.

Its fundamental characteristic: the auditor issues a public opinion on the regularity and fair presentation of the accounts. This opinion is annexed to the annual accounts and filed with the official registers (the court registry in France, the NBB in Belgium, the Commercial Register in Switzerland, the competent authorities depending on the Free Zone in the UAE).

The contractual audit (agreed-upon procedures, due diligence)

The contractual audit is voluntary. A company requests an audit because it needs one to:

• Reassure an investor ahead of a fundraising

• Prepare a business disposal (vendor due diligence)

• Validate an acquisition (acquirer due diligence)

• Secure a large bank loan

• Strengthen the confidence of a strategic commercial partner

• Set up robust internal controls

The scope is negotiated between the company and the auditor (a review of cash only, a full audit, a thematic audit of inventories or off-balance-sheet commitments, etc.). The opinion issued is not public: it is delivered to the party commissioning the engagement.

⚠️ Note: a statutory auditor or company auditor can carry out both statutory and contractual engagements, subject to the independence rules applicable in each jurisdiction.

The thresholds that trigger a statutory audit, by jurisdiction

This is the most consulted table on this page: at what point does the audit stop being an option and become an obligation?

France — Commercial companies

Since ordinance No. 2023-1142 of 6 December 2023, the thresholds for the mandatory appointment of a statutory auditor are aligned with the European definition of small companies.

The appointment is mandatory if two of the following three thresholds are exceeded over two consecutive financial years:

Criterion	Threshold (since 2024)
Total balance sheet	> €5 million
Turnover (excl. VAT)	> €10 million
Average headcount	> 50 employees

References: articles L.823-1 and D.823-1 of the Commercial Code.

Special cases: an SAS that another company controls or that it controls, and associations receiving more than €153,000 in annual public subsidies, must appoint a statutory auditor with no threshold condition.

Belgium — Commercial companies

The Companies and Associations Code (CSA) defines the "small company" in article 1:24: a company that does not exceed more than one of the following three criteria over two consecutive financial years.

Beyond that, the appointment of a company auditor becomes mandatory.

Criterion	Threshold
Total balance sheet	> €6 million
Annual turnover (excl. VAT)	> €11.25 million
Average headcount	> 50 FTE

Reference: CSA articles 1:24 and 3:72. The supervisory authority is the Institute of Company Auditors (IRE/IBR).

Switzerland — Public limited companies and Sàrls

Switzerland distinguishes between two very different regimes:

Ordinary audit (art. 727 CO): mandatory for companies open to the public (notably listed ones) and for companies that exceed two of the following three thresholds over two consecutive financial years:

Criterion	Threshold
Total balance sheet	> CHF 20 million
Turnover	> CHF 40 million
Average annual headcount	> 250 FTE

Limited audit (art. 727a CO): mandatory for all other public limited companies and Sàrls, save for the option to "opt out of the limited audit" (opting-out) if the company has fewer than 10 full-time jobs on an annual average and all shareholders consent (art. 727a(2) CO).

The supervisory authority is the Federal Audit Oversight Authority (FAOA).

United Arab Emirates — LLCs and Free Zones

The Emirati framework is more uniform: an audit is largely mandatory from incorporation.

Mainland (LLC): Federal Decree-Law No. 32 of 2021 on Commercial Companies requires the keeping of accounts compliant with international standards and the annual audit of the financial statements (articles 27 and 102).

Free Zones: the majority of Free Zones (DMCC, JAFZA, DAFZA, RAKEZ, ADGM, DIFC, Ajman Free Zone…) require their companies (FZE, FZCO) to file audited financial statements annually. The details vary from one Free Zone to another.

Corporate Tax (in force for financial years beginning on or after 1 June 2023): Ministerial Decision No. 84 of 2025 — which replaced Ministerial Decision No. 82 of 2023, effective for tax periods beginning on or after 1 January 2025 — requires the production of audited financial statements for standalone companies whose revenue exceeds AED 50 million over the tax period, or that claim Qualifying Free Zone Person status.

It also requires all tax groups to prepare audited special-purpose financial statements, regardless of that revenue threshold.

Accounts format: IFRS (or IFRS for SMEs for smaller entities) is the reference standard.

The players: who can audit in 2026?

Depending on the jurisdiction, the auditor holds a different title and answers to a specific supervisory authority. This dimension is not incidental: it determines the legal value of the audit opinion.

France

• Title: Statutory Auditor (Commissaire aux Comptes, CAC)

• Mandatory registration: the national list of statutory auditors, kept by the High Authority for Audit (H2A) since 2024 (formerly the H3C)

• Term: 6 renewable financial years

Belgium

• Title: Company Auditor (Réviseur d'Entreprises / Bedrijfsrevisor)

• Mandatory registration: the public register of the Institute of Company Auditors (IRE/IBR)

• Term: 3 renewable years

Switzerland

• Titles: Licensed Audit Expert (for the ordinary audit) or Licensed Auditor (for the limited audit)

• Mandatory registration: the public register of the Federal Audit Oversight Authority (FAOA), accessible online

• The leading professional association is EXPERTsuisse (~11,000 members)

United Arab Emirates

• Title: Auditor (generally a Chartered Accountant or Certified Public Accountant)

• Mandatory registration:

  • The Ministry of Economy to practise audit in the UAE

  • For Corporate Tax engagements: the register of accredited auditors of the Federal Tax Authority (FTA)

  • Additional registrations depending on the Free Zone

• A particularity: the Big Four (Deloitte, PwC, EY, KPMG) and the main mid-tier firms have historically been very well established in the Emirati market

How an audit engagement unfolds: the six steps

Whatever the jurisdiction, an audit engagement always follows the same general methodology, governed by the ISA standards (International Standards on Auditing) or their national adaptations.

1️⃣ Acceptance of the engagement

The auditor assesses their independence from the audited company, identifies potential conflicts and formalises the terms of the engagement in an engagement letter.

2️⃣ Planning

The auditor analyses the company's environment, identifies the significant risks (areas where an error or fraud would have a material impact on the accounts), sets the materiality threshold and plans their procedures.

3️⃣ Assessment of internal control

The auditor tests the company's internal controls over the key cycles (purchases, sales, payroll, cash, inventories). The stronger the internal control, the more the auditor can rely on it and reduce their substantive tests.

4️⃣ Substantive tests

The most visible phase for the audited company: the auditor performs direct checks on the accounts (bank reconciliations, customer/supplier confirmations, physical stock counts, inventory valuations, review of significant contracts, verification of cut-off, etc.).

5️⃣ Synthesis and conclusion

The auditor gathers their findings, assesses their potential impact on the accounts and discusses any adjustments with management.

6️⃣ Audit report

The auditor issues their opinion in a formal report:

• Unqualified opinion: the accounts give a true and fair view

• Qualified opinion: the accounts give a true and fair view, except for a specific point identified

• Adverse opinion: the accounts do not give a true and fair view

• Disclaimer of opinion: the auditor was unable to obtain sufficient evidence to conclude

This report is annexed to the annual accounts and filed with the competent authorities.

How much does an audit engagement cost in 2026?

Audit fees depend on several variables: the size of the company, the complexity of the business model, the number of subsidiaries, an international footprint, the quality of internal control, the sector, the urgency, and the calibre of the chosen firm.

The ranges observed on the market in 2026:

Jurisdiction	Micro / very small	SME	Mid-cap
🇫🇷 France	€4,000 – 8,000	€8,000 – 30,000	€30,000 – 100,000
🇧🇪 Belgium	€3,500 – 7,000	€6,000 – 25,000	€25,000 – 80,000
🇨🇭 Switzerland (limited audit)	CHF 3,000 – 8,000	CHF 5,000 – 15,000	—
🇨🇭 Switzerland (ordinary audit)	—	CHF 12,000 – 40,000	CHF 40,000 – 150,000
🇦🇪 UAE	AED 5,000 – 15,000	AED 8,000 – 25,000	AED 25,000 – 100,000

Sources: rate cards provided by the independent and mid-tier firms of the four jurisdictions; benchmarks published by the CNCC (the French statutory auditors' body), the IRE, EXPERTsuisse and the Emirati professional bodies. These ranges are indicative and may vary significantly according to the real complexity of the engagement.

The variables that push the quote up

Multi-entity: a company with several subsidiaries, branches or permanent establishments mechanically costs more (consolidation, intercompany transactions, multi-currency).

First audit (initial audit): a company's first audit is generally 20 to 40% more expensive than the following ones, because the auditor has to review the history and assess the opening balances.

Weaknesses in internal control: if the auditor cannot rely on strong internal controls, they must extend their substantive tests.

Urgency: an audit carried out on a very short timeline (typical ahead of an imminent disposal) can cost 30 to 50% more than a planned audit.

Regulated sectors: crypto-assets, fintech, ESG, real estate, financial services… some sectors require specific procedures that increase the cost.

Firm reputation: a Big Four firm generally charges 2 to 4 times more than a mid-tier equivalent in competence, for a comparable engagement, for an SME or a mid-cap. This premium is justified for listed groups or international mid-caps with market requirements, much less so for a standard SME.

The contractual audit: an under-used tool

Beyond the legal obligation, the contractual audit remains a powerful tool too often overlooked by SME directors.

Typical use cases

Ahead of a Series A or B fundraising: a contractual audit focused on the last 24 months reassures investors about the quality of the reported KPIs (ARR, MRR, churn rate, gross margins). Typical cost: €10,000 to €25,000 for an SME.

Ahead of a business disposal: the Vendor Due Diligence (VDD) anticipates the buyer's questions and identifies the weak points to correct before going to market. It speeds up the closing and limits price negotiations over the "skeletons in the closet".

During an acquisition: the acquirer due diligence validates the target's accounts and identifies off-balance-sheet commitments, ongoing litigation, and unprovisioned social or tax liabilities.

To structure internal control: a thematic audit (a review of a particular cycle — purchases, payroll, inventories…) helps identify process gaps and put fixes in place before a risk materialises.

To reassure a banking partner: a voluntary audit of the accounts facilitates obtaining credit lines, factoring or large-scale bank guarantees.

How to frame a contractual audit engagement

Three prerequisites for a successful contractual audit:

1. Define the scope precisely: a full or thematic audit, consolidated or statutory accounts, the period examined, the depth of testing

2. Choose a suitable firm: a Big Four is not always the best choice for a focused SME engagement — a mid-tier or independent firm can offer more pragmatism and a better price

3. Plan the timeline: a serious audit engagement takes at least 3 to 6 weeks depending on complexity; allow 2 to 3 months for a full VDD

Big Four, mid-tier or independent: how to choose?

This is the question every director asks when appointing their auditor. The honest answer: the choice depends on your company's profile, not on the firm's prestige.

Big Four (Deloitte, PwC, EY, KPMG)

Relevant for:

• Listed companies

• International multi-jurisdiction groups

• Companies raising more than €50M or in an IPO process

• Sectors where the auditor "brand" is required by counterparties (investment banks, top-tier funds)

Limitations:

• Markedly higher fees (2 to 4× mid-tier)

• Rapid team rotation (high turnover)

• Standardised methods, sometimes rigid for an SME

• The director rarely interacts with the signing partner

Mid-tier (BDO, Forvis Mazars, Grant Thornton, RSM, Baker Tilly, Crowe…)

Relevant for:

• Mid-caps with an international presence

• Ambitious SMEs preparing a growth transaction

• Companies wanting a high methodological standard without the Big Four premium

Limitations:

• Always more expensive than a local independent firm

• Uneven presence across jurisdictions

Independent firms

Relevant for:

• Local very small businesses and SMEs with a mainly domestic activity

• Companies seeking a personal relationship with the partner

• Engagements where command of local specifics (tax, sector) matters more than the brand

Limitations:

• More limited capacity for complex multi-jurisdiction engagements

• Financial independence varying with the size of the firm

The three questions to ask any auditor before signing

1. Who will be the signing partner, and how many days per year will they personally devote to our engagement? (Avoids the "star partner + interchangeable junior team" effect)
   

2. What is your sector experience in our line of business? (An auditor discovering your sector will bill more ramp-up time)
   

3. What are your materiality criteria and your approach to internal control? (Allows you to calibrate the real scope of the substantive tests)

FAQ — Frequently asked questions

My company exceeds the French thresholds this year for the first time. When must I appoint a statutory auditor?

You must appoint a statutory auditor as soon as the thresholds are exceeded over two consecutive financial years. The appointment takes place at the ordinary general meeting that approves the accounts of the second year of exceedance.

Plan ahead: identify your auditor several months before the general meeting so you have time to compare and negotiate fees.

Can I appoint my accountant as my statutory auditor?

No. The accountant and the statutory auditor are two incompatible engagements for the same company. The accountant keeps the books; the statutory auditor audits them.

This separation guarantees the auditor's independence and the integrity of their opinion. This rule is universal across our four reference jurisdictions.

Does a statutory audit cover the detection of internal fraud?

The auditor's role is to detect material errors or fraud that have an impact on the accounts. Their role is not to carry out an exhaustive anti-fraud audit.

If you suspect fraud, you must commission a forensic audit (a separate engagement, generally carried out by firms specialised in financial investigations).

Is a statutory audit tax-deductible?

Yes. Statutory audit fees are a deductible expense for tax purposes in all CryviTis jurisdictions (France, Belgium, Switzerland, UAE). Keep the engagement letter and invoices as supporting documents.

What happens if I refuse to cooperate with my auditor?

The auditor has the legal power to access all accounting records and to request any information relevant to their engagement. A refusal to cooperate exposes the director to:

• An adverse opinion or a disclaimer of opinion in the report (very damaging to the company's credibility)

• Criminal penalties in some jurisdictions (obstructing a statutory auditor's engagement in France, for example, is punishable under article L.820-4 of the Commercial Code: 5 years' imprisonment and a €75,000 fine)
