What is the Tax Consolidation Regime and why can it benefit your company?

November 21, 2025

The tax consolidation regime is a key tool for business groups seeking to optimize their taxation. At Resitax, tax experts in Mallorca, we advise companies through our tax advisory service in Mallorca to legally, securely, and efficiently reduce their tax burden.

This system allows all companies in a group to be integrated as a single taxpayer for the purposes of Corporate Income Tax, generating numerous advantages and savings opportunities.

Main advantages of the Tax Consolidation Regime

1. Immediate compensation of losses and profits within the group

Under this system, a business group can offset the tax losses of some companies with the profits of others in the same tax year.
This allows:

  • Reduce the group's taxable base.
  • Optimize the tax result each year.
  • To mitigate the impact of economic fluctuations between subsidiaries.

2. More flexible application of incentives and deductions

The requirements and limits for tax incentives, deductions and benefits are calculated at the group level.

This makes it possible:

  • To more easily meet the required conditions.
  • Take advantage of greater tax benefits.
  • Optimize the tax planning of the corporate group.

3. Tax neutrality in intragroup transactions

Profits derived from transactions between companies within the same group are not taxed until those transactions are carried out with third parties.
This tax treatment:

  • It increases the group's efficiency.
  • It facilitates internal reorganizations.
  • It allows for more flexible corporate management.

4. Simplification of tax obligations

This system also reduces the administrative burden by:

  • Simplify withholdings.
  • Reduce documentation in related-party transactions.
  • Centralize obligations in a consolidated declaration.

Requirements to apply the Tax Consolidation Regime

1. Existence of a dominant company (holding company)

There must be a dominant society that:

  • Own at least 75% of the share capital of its subsidiaries (70% if the parent company is listed).
  • Have the majority of the voting rights.
  • Maintain your involvement, either directly or indirectly.

What if the holding company is foreign?

If the parent company is not resident in Spain, the Spanish subsidiaries can still benefit from the tax regime, provided they meet the requirements.
This is common in international groups with operating subsidiaries in Mallorca.

2. Mandatory inclusion of all companies in the group

When applying the regime:

  • All companies in which the company holds at least a 75% stake must be integrated.
  • None of them can be selectively excluded.
  • The tax group must be properly structured.

3. Agreement of the administrative bodies

It is essential that:

  • All companies (the holding company and subsidiaries) approve the application of the regime.
  • The decision will be made before the end of the fiscal year.
  • Notify the Tax Office within the deadline.
  • The regime will take effect from the following fiscal year.

Is this regime suitable for your company or business group?
