Introduction
Mutualists expecting a refund on their overpaid IRPF taxes now face new obstacles. After a Supreme Court ruling confirmed their right to this refund, the Tax Agency initially set up a simple and fast procedure. However, the government has recently changed the process, making it more complex and delaying payments until 2028.
This change has sparked criticism from affected individuals and tax professionals. Both tax inspectors and financial advisors argue that the new system violates constitutional principles and burdens taxpayers with unnecessary bureaucracy.

The Root of the Problem: Double Taxation
Controversy began with a Supreme Court ruling in February 2023. The decision acknowledged that retirees who had contributed to mutual labor funds suffered from double taxation. When they paid into these funds, they could not deduct their contributions from taxable income. Later, their pensions were classified as taxable income, forcing them to pay taxes on the same funds twice.
The ruling allowed mutualists to deduct 25% of contributions made between 1967 and 1978 and 100% of those made before 1966 from their taxable income. Initially, the decision benefited former banking employees. However, it soon set a precedent for workers in sectors such as construction, electricity, metalwork, and fishing.
The Initial Refund System: Simple and Efficient
To comply with the Supreme Court’s decision, the Tax Agency first introduced a streamlined system. A digital form allowed affected individuals to claim their refunds quickly.
Thanks to this system, approximately €1.325 billion was refunded by November 2024. The process was widely praised for being fast and accessible, avoiding unnecessary bureaucratic delays.
The New System: A Bureaucratic Nightmare
Despite the initial success, the government has complicated the process. Mutualists now need to submit additional documents, and the refund timeline has been stretched to 2028.
Tax inspectors strongly oppose this decision. They argue that it is both unjustified and inefficient. The change contradicts the principle of good administration and imposes excessive delays. In some cases, beneficiaries may not even live long enough to receive their refunds.
The Spanish Association of Tax Advisors (Aedaf) has also criticized this shift. They claim it violates the principles of proportionality and legal certainty. Many retirees depend on these refunds, and any delay can affect their financial stability.
What Can Affected Mutualists Do?
Despite the difficulties, mutualists still have legal options to claim their IRPF refunds.
- Verify Eligibility – First, check if your case qualifies under the Supreme Court ruling.
- Submit a Request – Although more complicated, the application can still be filed online through the Tax Agency’s website. Seeking professional advice is recommended.
- Track Your Application – Since the process has become slower, it is crucial to monitor its progress and respond to any additional requests from the authorities.
- File an Appeal – If the Tax Agency rejects the claim or imposes unfair conditions, mutualists can appeal to the Economic-Administrative Tribunal or take legal action.
Tax professionals advise acting quickly, as future changes might create even more uncertainty.
Conclusion: A Growing Concern
The Tax Agency’s sudden change in policy has frustrated thousands of mutualists. What was once a straightforward process has turned into a bureaucratic maze.
Both tax inspectors and financial advisors urge the government to reconsider. However, until that happens, affected individuals must prepare for a lengthy battle to recover the money they are legally owed.
