Tax consolidation in Spain: what it is, requirements and key practical implications

Tax consolidation in Spain is a special, voluntary corporate tax regime that allows a group of companies to be taxed as a single taxpayer by filing a joint return.

Regulated under Chapter VI of Title VII of Law 27/2014 on Corporation Tax, this scheme allows the group’s tax liability to be optimised by treating it as a single tax unit, rather than analysing each entity individually.

What is a tax group?

In order to apply the tax consolidation regime, there must be a tax group comprising a parent company and one or more subsidiaries.

Parent company

The parent entity must fulfil, amongst others, the following requirements:

  • have legal personality
  • be subject to, and not exempt from, corporation tax
  • hold, directly or indirectly, at least 75% of the share capital and the majority of the voting rights of the subsidiary entities on the first day of the tax period in which this tax regime applies
  • maintain such a shareholding throughout the tax period

Dependent entities

Dependent entities that are in the process of being wound up due to financial losses may not form part of the group, unless such a situation is rectified in accordance with the law.

Dependent entities must:

  • have legal personality
  • be subject to, and not exempt from, corporation tax

The tax group shall cease to exist when the parent entity loses that status.

Inclusion and exclusion of entities in the tax group

Entities that fulfil the share requirements must be included in the tax group from the following tax period.

In the case of newly established entities, their inclusion shall take effect from the moment of their incorporation.

Conversely, entities that do not fulfil the requirements shall be excluded from the group with effect from the same tax period in which such circumstance arises.

Application of the tax consolidation regime

The application of the regime requires the express agreement of all entities in the group, adopted by their respective governing bodies.

This agreement must be formalised during the tax period preceding that in which the regime is intended to be applied. 

Determination of the tax group’s taxable base

The tax group’s taxable base is determined by aggregating the individual taxable bases, incorporating certain specific adjustments.

Eliminations and additions

Transactions between group entities must be eliminated to avoid double counting, in accordance with the criteria of the Standards for the Preparation of Consolidated Financial Statements. 

Subsequently, such eliminations shall be added to the tax base where applicable.

 Limitation on the deductibility of financial expenses

Net financial expenses shall be understood as the difference between financial income and financial expenses, excluding non-deductible expenses.

Net financial expenses shall be deductible up to a limit of 30% of the operating profit for the financial year. In any event, net financial expenses for the tax period amounting to 1 million euros shall be deductible, regardless of the operating profit.

In addition, financial expenses arising from debt incurred for the acquisition of shares or equity capital of any type of entity joining a tax consolidation group shall be deductible up to an additional limit of 30% of the operating profit of the acquiring entity or tax group.

The limit shall not apply:

  • In the tax period in which the shares are acquired, if the acquisition is financed by debt, up to a maximum of 70% of the acquisition price.
  • In subsequent tax periods, provided that the amount of the debt is reduced by at least the proportion corresponding to each of the following 8 years, until the debt reaches 30% of the acquisition price.

Under no circumstances shall income, expenses or revenues that have not been included in the tax base form part of the operating profit.

Financial expenses for the period that do not reach the established limit shall be carried forward to tax periods ending within the next five consecutive years.

Limitation on the offsetting of tax losses

Tax loss carry-forwards generated by an entity prior to its inclusion in the tax group may be offset up to a limit of 70% of that entity’s individual tax base.

Furthermore, there are temporary measures (2023–2025) limiting the inclusion of tax loss carry-forwards to 50% when determining the group’s tax base.

Formal obligations: tax return forms

  • Form 200

All entities within the group, including the parent company, must file the corresponding individual corporation tax returns, which must be completed to calculate the theoretical net tax amounts for the respective entities (“Net Tax Liability”).

  • Form 220

The parent company of the group must submit the specific tax return form for tax groups in order to be taxed jointly as a single entity.

  • Form 222 In April, October and December, advance payments of corporation tax must be made.

The instalment payment is calculated on the tax base for the period covering the first 3, 9 or 11 months of each calendar year, after deducting allowances, withholdings and payments on account made, as well as any instalment payments already paid.

The parent company of the group is responsible for filing this return.

Tax rates

Net turnover > €10 million 24%
Net turnover < €10 million 17%

(*) As a general rule. The tax rate must be calculated based on the tax rate applicable in the annual Corporation Tax return.

Additionally, companies with a net turnover exceeding €10 million are subject to the minimum payment.

The minimum payment applies when the amount payable is less than 23% of the profit shown in the profit and loss account for the first 3, 9 or 11 months of each financial year.

Only instalment payments made during the tax period may be deducted.

Conclusion

The tax consolidation regime in Spain is a key tool for optimising the taxation of business groups.

However, its application requires a detailed analysis of its implications, both in terms of tax planning and compliance with formal obligations.

Proper structuring of the group and appropriate planning allow for the maximisation of its advantages and the minimisation of associated risks.
