1. Introduction

Competition law in tax advisory concentration in Morocco concerns the regulation of mergers, acquisitions, market consolidation, strategic partnerships and dominant positions among businesses providing tax consultancy, tax planning, tax compliance, transfer-pricing advice, corporate tax services and international taxation services.

The Moroccan tax advisory industry is an important component of the professional services market. It includes:

International accounting and consulting networks.

Moroccan tax advisory firms.

Chartered accountants and audit firms.

Corporate tax consultancy businesses.

Transfer-pricing and international tax specialists.

Legal and financial advisory firms.

Independent tax consultants and specialist boutiques.

Concentration can improve the quality of tax advice, provide access to international expertise and create economies of scale. However, excessive consolidation can reduce competition, increase advisory fees, restrict client choice and strengthen the market power of a small number of professional service providers.

Morocco regulates these issues primarily through Law No. 104-12 on Freedom of Prices and Competition, as amended by Law No. 40-21, together with the institutional framework governing the Moroccan Competition Council.

An important distinction is necessary: Morocco has competition decisions concerning accounting, auditing and consulting professions, but there is not an established body of six Moroccan judicial precedents specifically concerning mergers between tax advisory firms. Accordingly, this explanation distinguishes Moroccan decisions from relevant comparative European case law.

2. Legal framework governing tax advisory concentration

A. Law No. 104-12 on Freedom of Prices and Competition

Law No. 104-12 is the principal legislation governing competition and economic concentration in Morocco.

It regulates:

Economic concentrations.

Anti-competitive agreements.

Abuse of dominant positions.

Market foreclosure.

Restrictive commercial practices.

Competition-related investigations and sanctions.

Tax advisory firms are undertakings for competition-law purposes when they carry out economic activities involving the provision of professional services.

Consequently, their commercial mergers and acquisitions can fall within the scope of Moroccan merger control.

B. Law No. 20-13 concerning the Competition Council

The Competition Council is responsible for supervising competitive market conditions and examining economic concentrations.

Its functions include:

Reviewing mergers and acquisitions.

Investigating anti-competitive practices.

Examining complaints involving restrictive conduct.

Evaluating market dominance.

Imposing or recommending appropriate competition remedies within its legal powers.

C. Law No. 40-21

Law No. 40-21 amended the Moroccan competition framework.

The updated framework strengthens the institutional and procedural arrangements applicable to competition enforcement, including economic concentration control.

D. Relevant professional regulation

Tax advisory concentration can also involve professional rules governing:

Chartered accountants.

Statutory auditors.

Professional independence.

Confidentiality.

Conflicts of interest.

Professional qualifications.

Permissible business structures.

Competition law must therefore be applied alongside applicable professional regulations.

3. Meaning of concentration in the Moroccan tax advisory market

Concentration occurs when previously independent businesses combine or when one undertaking obtains decisive influence over another.

Common examples include:

1. Horizontal concentration

Two competing tax advisory firms merge.

Example: Two Casablanca-based corporate tax advisory firms combine their operations.

2. Vertical concentration

A tax advisory firm acquires a business providing accounting software, tax compliance technology or corporate accounting services.

3. Conglomerate concentration

A large financial services group acquires a tax advisory firm to expand its professional services portfolio.

4. Acquisition of control

An international consultancy acquires the majority of shares or voting rights in a Moroccan tax advisory business.

5. Joint ventures

Two international advisory networks establish a jointly controlled Moroccan tax consultancy.

6. Professional network consolidation

Several accounting and tax consultancy businesses combine their operations, client relationships, technology platforms and professional resources.

The legal question is not simply whether the firms have merged. It is whether the transaction creates or strengthens market power in a manner capable of harming competition.

4. Moroccan merger notification thresholds

Under the amended Moroccan framework and the implementing regulations, an economic concentration must be notified when at least one of the following conditions is met:

These are alternative notification tests, not cumulative requirements.

The market-share test is particularly important for specialised tax advisory services. A transaction may require notification even where the turnover tests are not met.

Example:

Suppose three Moroccan tax advisory firms combine their operations and collectively account for 45% of the relevant market.

Even if their combined turnover does not satisfy the monetary thresholds, the market-share test may trigger notification.

The parties must assess the relevant market carefully, including the possibility of separate markets for transfer pricing, international taxation, corporate tax compliance and specialised tax litigation advice.

The transaction must not be implemented before the required approval.

5. Relevant market definition in tax advisory services

Market definition is one of the most important aspects of concentration analysis.

The Competition Council must determine whether tax advisory services constitute one broad market or several specialised markets.

A. Corporate tax advisory market

This market includes advice on corporate income tax, tax deductions, tax exemptions, tax structuring and corporate tax compliance.

B. International tax advisory market

This includes:

Cross-border taxation.

Double taxation agreements.

International tax planning.

Permanent establishment issues.

Foreign investment taxation.

C. Transfer-pricing advisory market

Transfer pricing involves determining whether transactions between associated enterprises comply with the arm's-length principle.

Specialised transfer-pricing services may constitute a distinct relevant market because they require particular expertise and international networks.

D. Tax compliance and reporting market

This includes tax return preparation, tax documentation, filing assistance, electronic tax reporting and regulatory compliance.

E. Tax dispute and litigation advisory market

This market includes assistance with tax audits, administrative appeals, tax assessments and proceedings before competent courts.

F. Digital tax advisory market

This involves automated tax calculations, artificial intelligence-based tax compliance, digital reporting platforms and cloud-based tax consultancy.

Why market definition matters: If two firms are the principal providers of transfer-pricing services, their merger may create substantial market power even if many smaller firms continue to operate in the general accounting and tax consultancy market.

6. Competitive risks arising from tax advisory concentration

6.1 Creation of dominant market positions

When leading tax advisory firms merge, they may obtain considerable influence over pricing and commercial conditions.

Possible consequences include:

Higher professional fees.

Reduced bargaining power for corporate clients.

Less competitive pressure.

Reduced availability of independent advice.

Greater dependence on large consultancy networks.

A dominant position is not automatically unlawful. The concern arises when it is abused or when a concentration creates or strengthens a position that significantly threatens effective competition.

6.2 Elimination of independent tax advisory firms

Large acquisitions can remove smaller independent competitors from the market.

For example, an international consultancy might acquire a Moroccan tax advisory boutique specialising in transfer pricing.

If the acquired business was an important independent competitive constraint, the transaction could substantially reduce competition.

6.3 Restriction of client choice

Concentration may reduce the number of independent advisers available to multinational companies, banks, manufacturers and small businesses.

This is particularly significant when clients require independent tax opinions, second opinions or advice on complex cross-border transactions.

6.4 Conflicts of interest

A large consultancy may provide tax advisory services to competing businesses.

Following consolidation, it may become difficult to maintain effective safeguards concerning:

Confidential client information.

Commercially sensitive tax strategies.

Transfer-pricing documentation.

Corporate restructuring plans.

Tax litigation strategies.

Although professional confidentiality is primarily addressed through professional and other applicable laws, conflicts of interest can also affect the competitive consequences of consolidation.

6.5 Predatory and exclusionary conduct

A powerful advisory group might use its financial resources to exclude smaller competitors through:

Below-cost pricing strategies.

Exclusive commercial arrangements.

Bundled accounting and tax services.

Restrictions on access to essential digital platforms.

Loyalty discounts designed to foreclose competing providers.

Such conduct must be examined under the applicable provisions governing anti-competitive practices and abuse of dominance.

6.6 Barriers to entry

Large tax advisory networks may possess advantages involving:

International client relationships.

Proprietary compliance software.

Extensive professional databases.

Experienced specialist personnel.

International referral arrangements.

These advantages are not unlawful by themselves. However, they may make market entry difficult when combined with exclusionary business practices or restrictive professional arrangements.

7. Anti-competitive agreements in the tax advisory sector

Competition concerns are not limited to mergers.

Tax advisory firms may also engage in agreements that restrict competition.

A. Fee-fixing agreements

Competing firms agree to charge identical minimum tax advisory fees.

B. Market allocation

Two consultancy firms agree that one will serve multinational corporations while the other will serve domestic businesses, with the intention of avoiding competition.

C. Bid rigging

Competing tax advisory firms coordinate their bids for government or corporate tax consultancy contracts.

D. Information exchange

Firms exchange future pricing information, client acquisition strategies or commercially sensitive business information.

E. Collective professional restrictions

A professional organisation establishes unnecessary restrictions that prevent qualified competitors from entering the market.

These practices must be assessed under the prohibition of anti-competitive agreements in Moroccan competition law.

8. Role of the Moroccan Competition Council

The Competition Council plays an important role in preserving competitive conditions in the tax advisory industry.

Its assessment may involve the following factors:

Possible remedies

If a concentration raises serious competition concerns, the Council may consider appropriate remedies, including:

Structural remedies, such as divestiture of a business unit.

Behavioural commitments concerning commercial conduct.

Non-discriminatory access arrangements.

Restrictions on certain exclusivity arrangements.

Safeguards against improper exchanges of competitively sensitive information.

Measures designed to preserve effective competition in specialised advisory markets.

The precise remedy depends on the identified competition harm and the applicable statutory procedure.

9. Important Moroccan decisions and comparative case laws

The following cases are relevant to understanding competition in professional services, accounting, auditing, consultancy and regulated advisory markets.

An important academic distinction: some are actual Moroccan competition decisions, while others are European Court of Justice judgments. The European judgments are comparative authorities, not binding Moroccan precedents.

Case 1. Moroccan Competition Council – Decision No. 80/D/2022 (28 July 2022)

Subject: Practices of the Order of Chartered Accountants in the audit market

This is particularly relevant to tax advisory concentration because it concerns the professional services market.

The Competition Council examined practices implemented by the Order of Chartered Accountants following a complaint by Ingénierie-Révision-Audit-Comptabilité (IRAC).

The matter concerned the accounting and financial audit market, including the effect of professional rules on competitive conditions.

Competition-law significance:

Professional organisations are not automatically exempt from competition law.

Professional rules can affect market entry and competition.

Restrictions imposed on professional service providers require appropriate legal justification.

Regulatory arrangements must not unnecessarily eliminate independent competition.

Application to Morocco: Professional rules governing tax advisers, accountants and audit professionals should not become instruments for protecting established firms against new competitors.

Case 2. Capgemini / Altran Technologies (Morocco, 2019)

Subject: Concentration in engineering consultancy services

The Moroccan Competition Council authorised the acquisition of exclusive control of Altran Technologies by Capgemini SE.

The Council considered the relevant engineering consultancy market and the fact that the parties commercialised most of their advisory services internationally.

The Council concluded that the transaction was not likely to distort competition in the relevant market at the horizontal or vertical level.

Competition-law significance:

The identity of the relevant professional services market matters.

International operations can influence the competitive assessment.

A concentration does not automatically produce anti-competitive effects.

Horizontal and vertical competitive relationships must both be considered.

Application to Morocco: A similar assessment could apply when an international tax consultancy acquires a Moroccan tax advisory firm. The Council would need to assess whether the parties compete directly and whether the transaction creates foreclosure risks.

Case 3. OCP SA / PwC Business Services (Morocco, 2025)

Subject: Acquisition of a professional consulting business

The Moroccan Competition Council published a notice on 10 July 2025 concerning OCP SA's proposed acquisition of exclusive control of PwC Business Services through the acquisition of its entire share capital and associated voting rights.

The announced activity of PwC Business Services included organisational consultancy.

The notice identified accounting and financial audit services among the economic sectors concerned.

Competition-law significance:

Acquisitions involving professional consulting businesses fall within merger-control scrutiny.

The identity of the acquiring undertaking and its existing economic activities are relevant.

The Council can invite interested third parties to submit observations.

Application to tax advisory concentration: This is a particularly useful Moroccan transaction to study because it illustrates how a major corporate group acquiring a professional services business can raise questions about market structure, independence and the scope of the relevant advisory market.

Important qualification: The July 2025 announcement is a notification notice, not itself a final judicial judgment or a finding that the transaction infringed competition law.

Case 4. Wouters and Others v Algemene Raad van de Nederlandse Orde van Advocaten (2002)

European Court of Justice · Case C-309/99

This case concerned professional rules adopted by the Dutch Bar concerning multidisciplinary partnerships between lawyers and other professionals, including accountants.

The European Court of Justice examined whether professional rules restricting certain forms of cooperation were incompatible with European competition law.

The Court recognised that certain restrictions could be justified by legitimate professional requirements, including independence and proper administration of justice, provided they were necessary for those objectives.

Competition-law principles:

Professional organisations may be subject to competition rules.

Professional independence can justify certain restrictions.

Restrictions must be assessed in their regulatory context.

Professional regulation should not become an unnecessary barrier to competition.

Application to Morocco: A tax advisory firm combining with an accounting, auditing or legal consultancy business must consider professional independence and conflicts of interest alongside competition requirements.

Case 5. Meca-Medina and Majcen v Commission (2006)

European Court of Justice · Case C-519/04 P

This case concerned sporting rules and the application of competition law to regulatory arrangements.

The Court explained that the restrictive effects of certain rules must be examined in the context of their legitimate objectives and whether those effects are inherent in and proportionate to those objectives.

Competition-law principles:

The purpose and context of a professional rule matter.

Not every restriction automatically constitutes an infringement.

Proportionality is important.

Legitimate regulatory objectives cannot be used to justify unnecessary restrictions.

Application to Morocco: Rules restricting multidisciplinary tax advisory partnerships should be evaluated according to their actual necessity, rather than simply accepted because they are imposed by a professional body.

Case 6. Ordem dos Técnicos Oficiais de Contas v Autoridade da Concorrência (2013)

European Court of Justice · Case C-1/12

This case involved the Portuguese professional body for certified accountants and its arrangements concerning compulsory professional training.

The Court examined the competition implications of rules adopted by a professional association that organised and controlled training activities.

The judgment is relevant because it demonstrates that professional organisations may engage in economic activity and that their regulatory position does not automatically place them outside competition law.

Competition-law principles:

Professional associations can fall within competition law.

Training and qualification arrangements can affect market access.

Rules that favour an association's own commercial activities require competition scrutiny.

Professional regulation must be distinguished from commercial activity.

Application to Morocco: If an association of tax professionals controls access to compulsory tax training in a way that unfairly favours certain advisory firms, competition concerns may arise.

Case 7. Consiglio Nazionale dei Geologi v Autorità Garante della Concorrenza e del Mercato (2013)

European Court of Justice · Case C-136/12

This case concerned the Italian professional body for geologists and professional fee-setting rules.

The Court considered the interaction between national professional regulations and European competition requirements.

It is relevant to professional advisory markets because fee-setting rules can affect price competition among independent service providers.

Competition-law principles:

Professional fee arrangements can affect competition.

Statutory authorisation does not necessarily eliminate competition-law scrutiny.

The regulatory context and proportionality of restrictions must be examined.

Professional associations should not unnecessarily restrict independent pricing.

Application to Morocco: Tax advisory firms should generally be free to determine their commercial fees independently, subject to applicable law. Collective minimum fee-setting arrangements may raise competition concerns.

Case 8. CHEZ Elektro Bulgaria and FrontEx International (2017)

European Court of Justice · Joined Cases C-427/16 and C-428/16

These cases concerned minimum remuneration rules for lawyers and their relationship with competition law.

The Court examined the role of national professional regulations and whether minimum fee arrangements were compatible with European competition requirements.

Competition-law principles:

Minimum professional fees can restrict price competition.

The legal and regulatory basis of fee rules matters.

Professional regulation must be assessed under competition principles.

Restrictions should not exceed what is necessary for legitimate objectives.

Application to Morocco: Similar reasoning can help evaluate whether collective minimum fees for tax consultancy services unnecessarily restrict price competition.

10. Case-law comparison

11. Economic effects of tax advisory concentration in Morocco

Concentration can generate both positive and negative economic effects.

A. Positive effects

1. Economies of scale

Large advisory firms can distribute technology, training and administrative expenses across a larger client base.

2. International expertise

Consolidation can improve access to specialists in international taxation, transfer pricing and cross-border corporate restructuring.

3. Technological innovation

Larger firms may invest in artificial intelligence, automated tax compliance and advanced financial reporting systems.

4. Improved service capacity

Consolidated firms may be better equipped to serve multinational corporations and large Moroccan businesses.

5. Professional development

Larger organisations can offer broader training opportunities and specialist career development.

B. Negative effects

1. Higher advisory fees: Reduced competition may allow dominant firms to increase prices.

2. Reduced independent competition: Smaller Moroccan tax advisory businesses may struggle to compete with international networks.

3. Market foreclosure: Large firms may use exclusive arrangements to restrict access to clients or important commercial resources.

4. Reduced innovation: Market dominance may reduce incentives to develop alternative advisory models.

5. Client dependency: Corporate clients may become dependent on a small number of large consultancy providers.

12. Hypothetical examples of concentration in Morocco

Example 1: Merger between two Casablanca tax advisory firms

Suppose Firm A and Firm B are independent competitors specialising in corporate tax consultancy.

They decide to merge.

Before the transaction:

Firm A holds 25% of the relevant market.

Firm B holds 20%.

Their combined position would be 45%.

The transaction may trigger the Moroccan market-share notification threshold.

The Competition Council would examine whether other competitors can adequately constrain the merged firm.

Example 2: Acquisition of a transfer-pricing specialist

Suppose an international consulting group acquires a Moroccan transfer-pricing consultancy.

The target business has specialised expertise and important multinational clients.

The Council may investigate whether the acquisition removes an important independent competitor or creates an ability to foreclose competing advisory businesses.

Example 3: Consolidation of digital tax platforms

Suppose two major tax compliance software businesses combine their operations.

The merged company subsequently controls a substantial portion of the technology used by Moroccan tax advisers.

The Council may examine whether competitors can access alternative technology and whether the merged business can impose discriminatory access conditions.

Example 4: Acquisition by a large industrial group

Suppose a major Moroccan industrial group acquires a tax advisory firm that previously provided services to several competing industrial businesses.

The transaction may raise questions concerning commercially sensitive information, conflicts of interest and the competitive independence of the acquired consultancy.

These concerns require examination under the relevant competition and professional confidentiality rules.

13. Regulatory challenges in Morocco

Several challenges arise when applying competition law to tax advisory concentration.

1. Difficulty defining the relevant market

Tax advisory services overlap with accounting, auditing, legal consultancy and financial advisory services.

2. International ownership structures

Global consulting networks can have complex ownership, control and referral arrangements that require careful assessment.

3. Limited specialist competition

Certain specialised services, particularly transfer pricing and international tax planning, may have relatively few qualified providers.

4. Professional independence

Competition authorities must distinguish legitimate professional safeguards from restrictions that unnecessarily protect established businesses.

5. Digital market concentration

Tax compliance platforms and automated advisory tools may create new forms of market power.

6. Confidentiality and information exchange

The integration of two firms can create risks involving confidential client information and commercially sensitive data.

14. Recommendations for strengthening competition governance

Morocco could strengthen competition in the tax advisory industry through the following measures:

Particular attention should be given to smaller Moroccan tax advisory firms because they can provide important competitive constraints on large international consultancy networks.

15. Important statutory provisions for examination

The following provisions of Law No. 104-12 are particularly relevant:

The applicable implementing regulations, including Decree No. 2-14-652 as amended, must also be consulted when determining notification requirements.

16. Overall legal analysis

Competition law in tax advisory concentration in Morocco is concerned with maintaining a balance between professional efficiency and competitive market structures.

A merger between two tax advisory firms should not be considered unlawful merely because it increases their combined market share. The central question is whether the transaction creates or strengthens market power in a manner that substantially restricts competition.

The Moroccan Competition Council must therefore consider:

The relevant tax advisory market.

The combined market share of the merging firms.

The competitive significance of independent advisers.

The availability of alternative professional services.

Potential increases in advisory fees.

Barriers to entry for new firms.

Risks arising from vertical integration.

The potential benefits of professional consolidation.

The Moroccan decision concerning the Order of Chartered Accountants, Decision No. 80/D/2022, is especially important for understanding competition issues in regulated professional services. The Capgemini/Altran transaction provides a useful Moroccan merger-control comparison, while the European judgments offer additional guidance concerning professional independence, fee restrictions and market access.

17. Conclusion

Competition Law in Tax Advisory Concentration in Morocco represents an important intersection between commercial regulation, professional independence, corporate taxation and economic development.

The consolidation of tax advisory businesses can improve expertise, technological capacity and international competitiveness. However, excessive concentration may undermine independent professional services, increase advisory costs and restrict access to specialised tax expertise.

Morocco's Law No. 104-12, the amendments introduced by Law No. 40-21 and the Competition Council's merger-control powers provide the principal legal framework for addressing these risks.

The ultimate objective should be to encourage efficient professional consolidation without allowing dominant advisory groups to eliminate independent competition.

Research note: The Moroccan examples and comparative European cases above should not be described as eight Moroccan tax-advisory merger judgments. The OCP/PwC item is a notified transaction, and the European judgments are comparative authorities. This distinction is important in academic legal writing.
