The concept of subsidiary layering in Indian corporate law has evolved as a regulatory response to concerns around opacity in ownership structures, fund diversion, and regulatory arbitrage. Section 2(87) of the Companies Act, 2013 defines a “subsidiary company” in terms of control, either through composition of the Board of Directors or control over more than one-half of total voting power. While the definition itself is foundational, the real regulatory restriction on layering emerges from the Companies (Restriction on Number of Layers) Rules, 2017, which impose a cap on the number of subsidiary layers that a company may have. This framework seeks to ensure transparency while balancing legitimate business structuring needs.

The 2017 Rules restrict companies from having more than two layers of subsidiaries, with certain exclusions carved out for wholly owned subsidiaries. The interpretation of “layer” has been a subject of technical debate, particularly in determining whether multiple wholly owned subsidiaries should be counted or excluded for the purpose of calculating layers. The Rules clarify that one layer of wholly owned subsidiary is permitted to be excluded, but beyond that, additional layers may trigger non-compliance. This creates practical challenges in complex group structures where intermediate holding companies are often used for operational, regulatory, or tax planning purposes.

The restriction becomes particularly intricate when read in conjunction with the concept of “control” under Section 2(27), which includes not only shareholding but also the right to appoint majority directors or exercise significant influence through contractual arrangements. This broad definition implies that even structures without direct equity ownership may fall within the ambit of subsidiary relationships if de facto control can be established. Consequently, companies must evaluate not only legal ownership but also governance arrangements, shareholder agreements, and voting rights to assess whether a layering violation exists.

An important dimension of layering restrictions is their interaction with foreign investment regulations under the Foreign Exchange Management Act (FEMA), particularly in the context of Overseas Direct Investment (ODI) and downstream investments. Indian companies investing abroad are subject to ODI regulations, which impose their own set of conditions on the number of layers and the nature of permissible investments. While FEMA does not explicitly replicate the two-layer restriction, regulatory scrutiny increases in cases involving multi-tiered offshore structures, especially where such structures may be perceived as vehicles for round-tripping or tax avoidance.

The interplay between the Companies Act and FEMA becomes critical in cross-border group structuring. For instance, an Indian holding company may establish a foreign subsidiary, which in turn sets up downstream subsidiaries in other jurisdictions. While such structures may be permissible under FEMA subject to reporting and compliance, they must still be evaluated against the layering restrictions under Indian company law. The absence of a fully harmonized framework between the two regimes creates interpretational challenges, particularly where foreign jurisdictions permit deeper layering as a matter of commercial practice.

Exemptions under the layering rules further complicate the analysis. Banking companies, non-banking financial companies (NBFCs), insurance companies, and government companies are generally exempt from the restriction, recognizing the unique nature of their regulatory environments. However, the scope and applicability of these exemptions must be carefully examined, especially in group structures involving both exempt and non-exempt entities. The presence of an exempt entity at one level does not automatically insulate the entire structure from scrutiny, and each layer must be evaluated independently.

From a structuring perspective, companies often adopt strategies to remain compliant while achieving business objectives. These may include flattening group structures, consolidating intermediate entities, or using joint venture arrangements instead of wholly owned subsidiaries to avoid classification as a “layer.” However, such structuring must be approached with caution, as regulatory authorities increasingly focus on substance over form. Artificial arrangements designed solely to circumvent layering restrictions may be challenged, particularly if they lack commercial rationale.

The compliance implications of violating layering restrictions are significant. Although the Rules do not prescribe explicit penal provisions within themselves, non-compliance may attract penalties under general provisions of the Companies Act, and may also trigger regulatory scrutiny in related areas such as related party transactions, loans and investments under Section 186, and disclosures in financial statements. Additionally, auditors and company secretaries play a critical role in identifying and reporting non-compliant structures, increasing the importance of proactive compliance reviews.

Judicial interpretation in this area is still evolving, and there is limited direct case law specifically addressing layering violations. However, broader principles from cases involving lifting of corporate veil and misuse of corporate structures are increasingly being applied. Tribunals have shown willingness to examine the intent and effect of multi-layered structures, particularly in cases involving fraud, diversion of funds, or oppression of minority shareholders. This indicates a trend towards stricter scrutiny of complex group arrangements.

In conclusion, the regulation of subsidiary layering under Section 2(87) read with the 2017 Rules represents a critical compliance area that requires careful legal and strategic consideration. The overlap with FEMA, the broad definition of control, and the evolving enforcement landscape make this a highly technical domain. Companies must adopt a holistic approach, integrating legal, financial, and regulatory perspectives to design structures that are not only efficient but also compliant and defensible. As regulatory focus intensifies, the ability to justify the commercial rationale behind group structures will be as important as meeting the letter of the law.
