The terms holding and business group are often used interchangeably, but they designate distinct concepts. Understanding the difference between the two is relevant not only from a conceptual standpoint, but also when designing efficient corporate structures and meeting the legal and accounting obligations that each implies.
What is a holding company?
A holding company is a company whose main purpose is the holding and management of participations in other companies (subsidiaries). It does not carry out productive or commercial activity of its own: its function is to control, coordinate, and optimize investments in the subsidiary companies. The income of a holding comes mainly from dividends, capital gains generated by the sale of participations, and in some cases from services rendered to the subsidiaries.
From a legal standpoint, a holding can be incorporated as any ordinary corporate form (SL or SA in Spain). However, to benefit from the most relevant tax advantages — such as the exemption on dividends and capital gains under Article 21 of the Corporate Income Tax Act — certain participation and holding period requirements must be met. In international contexts, there are specialized vehicles such as the Spanish Holding Vehicle for Foreign Securities (ETVE) which extend tax advantages on the receipt of income from abroad.
The holding is, in short, a conscious and voluntary structural design decision: it is created to centralize control, optimize taxation, protect assets, and facilitate the transmission of the business.
What is a business group?
A business group is a set of legally independent companies linked to each other by control or participation relationships. In Spain, the Commercial Code defines the group as the set of companies in which one — the parent — controls directly or indirectly the others — the subsidiaries.
A group can exist with or without a holding at the apex. What defines the group is not the formal structure at the top, but the unity of direction and effective control between the different entities. This reality has relevant accounting consequences: groups are required to draw up consolidated annual accounts when they exceed certain size thresholds (assets, turnover, number of employees).
Unlike the holding — which is a specific entity — the group is a relational concept: it is not an entity in itself, but the description of the relationship that exists between several entities. The group can emerge organically, as a company creates subsidiaries or acquires participations, without there being an explicit decision to “create a group”.
Main differences between holding and business group
Corporate structure
The holding is a specific legal entity: a company that owns participations in others. The group, on the other hand, is a relational concept that describes the relationship between several entities, regardless of how the apex of the structure is organized.
A holding can be the parent company of a group, but a holding can also exist without forming a group (if its participations are minority and there is no effective control). And a group can exist without an explicit holding, if control is exercised directly by a natural person.
Control and participation
In a group, control can be exercised through majority participation in capital, but also through contractual agreements, special voting rights, or appointments to management bodies. A holding, on the other hand, always acts through its direct participation in the share capital of the subsidiaries.
The control threshold for determining that a group exists is usually a majority of voting rights (more than 50%), although accounting regulations contemplate other situations of effective control (de facto participation, agreements with other partners) that also determine the existence of a group even if 50% is not formally exceeded.
Tax and accounting management
A well-structured holding can benefit from the tax consolidation regime in Corporate Income Tax, which allows offsetting losses of some group entities against profits of others and neutralizing intragroup operations. This regime requires the parent to hold at least 75% of the subsidiaries and for these to be resident in Spain or in the EU under certain conditions.
The business group, as a reality, requires drawing up consolidated accounts when the legal thresholds established in the Commercial Code are exceeded, regardless of whether there is a holding or not. This consolidation obligation involves additional audit work and presentation of aggregated financial statements that reflect the economic picture of the group as a unit.
Purpose of the structure
The holding is created fundamentally with specific purposes: tax optimization, asset protection, succession planning, or centralization of operational control. Its existence responds to a deliberate and planned strategic decision.
The business group, on the other hand, can emerge unplanned as a consequence of the natural growth of the business. A company that creates a subsidiary to expand into another market already forms a group, even though no one has made the explicit decision to “create a group”. This difference has practical implications: the group imposes obligations (consolidation, information on related parties) regardless of whether it was intentionally designed.
When is a holding and when is a business group appropriate?
A more precise question would be: when is it worth creating a holding structure above the group? Because the group emerges almost inevitably when there are several companies with common control. The real decision is whether it makes sense to add a holding at the apex of that structure or to maintain ownership directly in the hands of natural persons.
Creating a holding makes sense when the subsidiaries’ profits are recurring and you want to reinvest without paying taxes at personal level, when there is a need to protect accumulated assets from operational risks, or when succession planning or the entry of investors makes it advisable to centralize ownership. If none of these needs exists, adding a holding can be unnecessarily complex and costly.
Common errors in confusing both concepts
One of the most frequent errors is creating a holding without real economic justification: the structure is set up out of fashion or by imitating other people’s models, without there being clear benefits to offset the additional complexity. This generates maintenance costs without an equivalent return.
It is also common to confuse the obligation to consolidate accounts (which arises from the group) with the advisability of creating a holding. These are independent obligations and decisions that respond to different criteria. A group can be required to consolidate without there being a holding, and a holding may not generate a consolidation obligation if the group does not exceed the legal thresholds.
