The 1990 law that split Spanish football in two

In short: Spain’s 1990 Sports Act forced professional clubs to become sporting corporations, exempting four that arrived with healthy balance sheets. That exemption also handed them lighter taxation for twenty-five years, which the EU Court of Justice ruled illegal state aid in 2021. A year later, Spain scrapped the conversion requirement for everyone.

Spanish football has been split into two legal categories for thirty-five years. On one side, four clubs owned by their members. On the other, everyone else, owned by shareholders. That border was not drawn by tradition or by fanbase. It was drawn by a statute, and the test was accounting.

What the law actually did

The Ley 10/1990, Spain’s Sports Act of 15 October 1990, required clubs competing professionally to convert into sociedades anónimas deportivas (SADs), sporting corporations. The reasoning was accountability. Through the 1980s many Spanish clubs ran up debts nobody was liable for, and the state absorbed part of the damage.

Turning them into commercial companies put a name and capital behind every decision.

The law allowed an exception for clubs that had shown sound management under the associative regime. In the words of the statute’s own preamble, those maintaining “positive net worth during the four most recent financial years”. Four qualified: Real Madrid, FC Barcelona, Athletic Club and CA Osasuna.

The test is the part worth holding onto. Nobody asked about a club’s history, its social roots, or what its members wanted. They looked at the balance sheet. Clubs reaching 1990 out of the red kept their associative form; clubs reaching it in debt acquired shareholders. How that model works in practice is covered in what it means for a club to belong to its members.

The consequence nobody planned: tax

Keeping the associative form turned out to be more than a governance question. It had a direct fiscal effect.

In Spain, non-profit entities pay corporate tax at a lower rate than commercial companies. By not converting into SADs, the four clubs continued to be taxed as associations. Their competitors, obliged to become corporations, paid the general rate.

That gap persisted from 1990 to 2015.

From the Commission to the Court of Justice

In 2016 the European Commission concluded that this amounted to illegal state aid. Spain had favoured four undertakings — and for competition purposes a professional club is one — over their direct competitors. It ordered recovery, put at roughly €5 million.

The clubs appealed, and the case ran through both European courts to opposite results:

Date	Court	Outcome
2016	European Commission	Illegal state aid
February 2019	EU General Court	Annuls the Commission’s decision
4 March 2021	Court of Justice (C-362/19 P)	Sets aside that ruling, confirms the Commission

The 2021 judgment decided Commission v Fútbol Club Barcelona and definitively rejected the club’s action. The Court’s reasoning was procedural rather than sporting: when examining an aid scheme, the Commission is not required to establish how much each individual taxpayer actually benefited.

This is why the case matters beyond the sum involved. Five million euros spread across twenty-five years and four clubs is minor for entities now running nine-figure budgets. What matters is the classification. A regime designed to reward prudent management ended up formally declared unlawful public support.

The 2022 twist: the requirement disappears

While the courts worked through it, the framework changed entirely.

The Ley 39/2022 of 30 December 2022 replaced the 1990 act and removed the obligation to convert into a SAD. Entities competing professionally may adopt corporate form, but are no longer required to. The choice is theirs.

The legislator explicitly acknowledged that commercial form is not necessarily right for every club, a restrictive model Spanish legal scholarship had questioned for years.

The exception outlived the rule

The outcome carries an irony worth naming.

For thirty-two years, four clubs were the anomaly in a system compelling everyone else to be corporations. Their tax advantage was challenged, litigated all the way to Luxembourg, and clawed back.

Then the rule that made them exceptional was repealed. Today no Spanish club is required to be a SAD. The model the 1990 act treated as a tolerated residue is, in 2026, an option available to anyone.

What has not changed is the distribution. No LaLiga club has reversed its conversion, and the member-owned clubs still number four. Changing the legal form of a corporation with shareholders does not depend on a statute. It depends on those shareholders being willing to stop being shareholders.

Frequently asked questions

What is a sociedad anónima deportiva?

A sport-specific corporate form created by the 1990 Sports Act. It is a public limited company adapted to competition, with capital divided into shares and shareholders liable for the company’s assets.

Why aren’t Real Madrid, Barcelona, Athletic and Osasuna corporations?

They maintained positive net worth across the four financial years before the 1990 Sports Act and qualified for the exception it contained, which let well-run clubs keep their associative form.

Did they receive an illegal tax advantage?

Yes. On 4 March 2021, in Case C-362/19 P, the EU Court of Justice confirmed the European Commission’s 2016 decision classifying their tax regime as illegal state aid between 1990 and 2015.

Is conversion into a SAD still mandatory?

No. The 2022 Sports Act removed the obligation. Clubs competing professionally may choose their legal form.

Could a club return to being a members’ association?

The law no longer prevents it, but the decision belongs to the company’s shareholders rather than the legislator. To date no LaLiga club has reversed its conversion.
