Annual Compliance in Monaco 2026 – Deadlines, Fees & Penalties Explained

Annual Compliance in Monaco: Filing & Tax Requirements (2026 Guide)

Ensuring annual compliance in Monaco is critical for maintaining legal standing and avoiding severe penalties imposed by the government. Companies must prepare financial statements and submit them to the Trade and Industry Register as required by Monaco’s accounting obligations (Act no. 408/1945 & Act no. 1331/2007).

An official 2025 OECD Corporate Tax Statistics report shows Monaco reported zero country‑by‑country reports, reflecting strict domestic tax compliance but also limited multinational disclosures.

This 2026 guide provides a precise compliance calendar and checklist for meeting company annual filing deadlines in Monaco and fulfilling all documented corporate tax requirements.

Who Must File Annual Compliance Reports in Monaco?

Companies registered in Monaco must comply with annual reporting obligations. Key filing requirements include:

• Trading Companies Registered in the Trade and Industry Registry (RCI) are required to prepare and file annual financial accounts, including a balance sheet, profit and loss statement, and management report, with the RCI. This obligation applies to SARLs (Private Limited Liability Companies), SAMs (Joint‑Stock Companies), SCSs (Limited Partnerships), SNCs (General Partnerships), SCAs (Partnerships Limited by Shares), and Foreign Companies registered in Monaco.
• Attestations or Legal Certifications must accompany annual accounts when a statutory audit is not required; these attest that accounts meet legal requirements and must be issued by a Monegasque member of the Order of Public Accountants. Companies subject to compulsory audit (e.g., SAMs above threshold) must file audited accounts.
• Non‑Trading Companies Entered in the Special Register must submit an annual declaration confirming continued registration within one month of the anniversary of their initial registration each year. This declaration also confirms any amendments made during the year.
• Designated Information Officers are now required for both trading and non‑trading companies to maintain and report accurate basic company information and beneficial ownership details to the Business Development Agency.

Annual Compliance Snapshot: Key Deadlines at a Glance

Below is a precise and official compliance calendar for major annual obligations in Monaco, with governing bodies and statutory due dates based on current laws and official government guidance:

1. Annual Return / Confirmation Statement

Keeping accurate corporate records is a critical component of annual compliance in Monaco. Monaco requires an annual return, formally an annual confirmation statement, to ensure a non‑trading company’s registration data remains current and legally valid.

• Purpose: The confirmation statement verifies that a non‑trading company continues to operate and that its registration information, including any changes made during the year, is up to date in the Special Register of Non‑Trading Companies. Any registered non‑trading company must file it annually.
• Due Date: Companies must file this confirmation within one month following the anniversary date of their registration in the Special Register of Non‑Trading Companies.
• Filing Fee: The official fee is €25 for a private non‑trading company and €50 for a public limited company, payable with the annual confirmation declaration.
• Online Portal Steps:
  1. Download the DA‑SC form from the MonEntreprise portal under Legal and Accounting Requirements → Trade and Industry Registry
  2. Complete the form in duplicate with current company details.
  3. Submit or mail it with the fee to: Direction du Développement Économique – Service du Répertoire du Commerce et de l’Industrie, 9 rue du Gabian, 98000 Monaco.

2. Corporate Income Tax Return

Before reviewing procedures, annual compliance in Monaco requires accurate filing of the corporate income tax return and timely tax payment to the Department of Tax Services.

• Corporate Income Tax Rate: Monaco’s standard corporate income tax rate is 25 % for companies that generate more than 25 % of turnover from outside Monaco. This rate applies to accounting periods beginning on or after 1 January 2022.
• E‑Filing and Filing Procedure: Monaco requires the corporate income tax return to be submitted to the Department of Tax Services within three months after the end of the financial year, or before 1 April if the company uses a calendar year.
  • Submission Steps: obtain the “Déclaration des résultats” and necessary supporting documents; complete forms; and send them, including the required “Bordereau de règlement de l’impôt sur les bénéfices,” to the Department of Tax Services.
• Payment Schedule: Monaco requires four provisional tax installments of corporate tax to be paid annually in February, May, August, and November, each equal to 20 % of the prior year’s tax. The balance is settled with the tax return filing.

3. Audited or Unaudited Financial Statements

Companies must determine whether they must file audited financial statements or can file unaudited statements with a legal certification when meeting filing obligations with the Trade and Industry Registry.

• Audit‑Trigger Thresholds: Monaco law makes a statutory audit compulsory for all Sociétés Anonymes Monégasques (SAMs) and Sociétés en Commandite par Actions (SCAs), regardless of size. For SARLs (limited liability companies), SNCs (general partnerships) and SCSs (limited partnerships), an audit is mandatory when two of the following three thresholds are met in two consecutive financial years:
  • Total balance sheet assets > €1,500,000
  • Pre‑tax turnover > €2,500,000
  • More than 20 employees
• Accepted Accounting Standards: All companies must file annual financial statements (balance sheet, profit and loss account, and management report) with the Trade and Industry Registry (RCI). Statements must be signed by a qualified accountant. Monaco does not mandate IFRS for standard filings; companies follow the local accounting framework established under Monaco law.

4. Beneficial Ownership & KYC Declarations

Accurate beneficial ownership disclosure and KYC declarations are mandatory elements of annual compliance in Monaco for both trading and non‑trading companies.

• Register Requirement: Monaco entities registered with the Trade and Industry Register (RCI) must declare beneficial owners (natural persons holding ≥ 25% of capital/voting rights or exercising control).
• Filing & Updates: Beneficial ownership must be declared at incorporation and updated following any change in ownership or control within the legally prescribed period.
• Penalties: Failure to declare or update beneficial ownership may result in administrative or criminal sanctions under Law n° 1.362 (AML framework).

5. Payroll, VAT/GST & Other Periodic Filings

This section outlines mandatory periodic compliance tasks, including payroll administration, VAT declarations, and cross‑border reporting, all based solely on official Monaco government sources.

VAT (TVA)

• VAT returns are generally filed monthly.
• Quarterly filing permitted if annual VAT due < €4,000 (upon request).
• Annual return (January) required for VAT-exempt businesses.

Trade of Goods (DEB)

• Monthly declaration is required for goods traded with EU Member States (excluding France), due by the 10th working day after the reference month.

Payroll / Payment Declarations

• Employers must file the “Déclaration des rémunérations” before 1 April of the following year.

Penalties for Late or Inaccurate Filings in Monaco

Penalties for late or inaccurate submissions are central to maintaining annual compliance in Monaco, reflecting the principality’s strict regulatory regime. Official ordinances set out fines, interest charges, and potential enforcement actions for non‑filing, late filing, inaccuracies, and intentional misconduct.

• Corporate Tax Return Penalties: Late filing of a corporate tax return incurs a fixed penalty ranging between €15 and €75 under Article 34 of Sovereign Ordinance no. 3.152. Late payment of installments or final tax triggers a 3 % penalty, plus an additional 1 % for each month of further delay under Article 35 of Ordinance no. 3.152.
• Fines for Inaccurate or Missing Information: For reporting under certain mandatory disclosure regimes (e.g., Country‑by‑Country Report obligations), penalties start at €10,000 for non‑submission, rising to €100,000 for unresolved default, and €150 to €250 for inaccuracies, depending on regularization timing under Ordinance no. 6.713.
• Interest and Additional Penalties: Official guidance confirms that both CIT and VAT non‑filings or inaccuracies may trigger monthly interest charges and additional surcharges depending on the tax involved.
• Enforcement and Loss of Good Standing: Persistent failure to file or rectify defaults, particularly in financial reporting or tax compliance, subjects a company to administrative sanctions, loss of good standing with the Trade & Industry Register, and referral to judicial authorities.

Regulatory & Compliance Obligations

Ensuring full regulatory and compliance obligations in Monaco is critical for protecting corporate credibility, avoiding fines, and maintaining good standing with government authorities. From corporate tax returns and annual accounts to beneficial ownership updates and VAT filings, the scope of obligations can be complex and time-sensitive.

Engaging professional support, such as Commenda’s services, helps businesses navigate these requirements efficiently, ensuring all declarations are accurate, deadlines are met, and potential risks are mitigated, allowing management to focus on strategic growth rather than procedural compliance.

Common Mistakes & How to Avoid Them

When managing annual compliance in Monaco, companies often encounter recurring errors that can trigger fines, referrals, or reputational risks. Here are the top five, with guidance based on official government sources:

1. Incorrect Fiscal Year – Filing accounts or tax returns for the wrong fiscal year can result in rejection or penalties. Always align reporting with your registered year-end.
2. Missing Director Signatures – Annual accounts and confirmation statements must be signed by directors or authorized representatives. Missing signatures make filings invalid.
3. Under‑Reported Income – Incorrect reporting of turnover or taxable income can trigger reassessments, interest, and penalties. Ensure corporate income tax returns are accurate and complete.
4. Late Beneficial Ownership Updates – Changes in ownership must be updated within 30 days. Failure to comply may result in judicial referral under AML regulations.
5. Ignoring Currency Conversion – Foreign transactions or accounts must be reported in EUR using official conversion rates. Failure can cause misstatements in accounts and tax returns.
