Mutualistas: New Personal Income Tax Refund Calendar and Controversy

The controversy over the new repayment system centres on its retroactive effect, uncertainty and delayed refunds, which may be postponed for several years, as well as inconsistencies in administrative proceedings already under way. The Tax Agency says the new system is intended to make processing more orderly and consistent; critics among the mutualistas say it delays payment of what many regard as established rights.

1. Background: mutualistas’ refunds and Transitional Provision 2 of the Personal Income Tax Law

For years, personal income tax rules have recognised special situations for mutualistas, such as professionals affiliated with social welfare mutual societies as an alternative to the self-employed regime.

Transitional Provision 2 (DT2) of the Personal Income Tax Law governs how contributions to these mutual societies are included and offset. In certain circumstances, it allows taxpayers to seek a refund of personal income tax paid in earlier self-assessments, where contributions are recognised as having had specific tax treatment or as deductible.

Many mutualistas therefore filed requests with the Tax Agency to correct past returns and recover tax for years that had not become time-barred.

2. The effect of Final Provision 16 of Law 7/2024

Law 7/2024 of 20 December introduced a new system for processing these refunds through Final Provision 16 (DF16). It took effect on 22 December 2024, with significant consequences:

1. The previous refund application form for mutualistas under DT2 was discontinued.

2. Refund applications for 2019–2022 and earlier years that were not time-barred were cancelled if they had not been approved before 22 December 2024.

   • Even if an application had been submitted, it lapsed if the Tax Agency had not approved and paid the refund by that date.

   • The law specifies that these cancelled applications interrupt the limitation period, so the mutualista’s right to claim does not disappear.

3. Refunds already paid are unaffected: the decision remains final and is not revoked or reviewed under DF16.

As a result, many mutualistas who had already applied will have to submit their claims again under the new system introduced from 2025.

3. New application system and filing calendar

According to the information note, refunds for 2019, 2020, 2021 and 2022, as well as earlier years that are not time-barred, must be claimed one year at a time, alongside each year’s tax-return campaign:

• 2025: a form will be available to claim the 2019 refund and earlier years that are not time-barred.

• 2026: 2020 refund.

• 2027: 2021 refund.

• 2028: 2022 refund.

This staggered schedule appears intended to prevent the Tax Agency from receiving all prior-year claims at once. Each year, during the voluntary filing period, a specific form will be available on the Agency’s electronic office.

4. Main controversies

1. Retroactive effect and cancellation of pending applications. Critics say DF16 has a quasi-retroactive effect: pending refund requests, some filed months or years earlier, were cancelled unless approved before 22 December 2024. Mutualista groups question legal certainty because proceedings already under way were set aside, creating frustration and uncertainty.

2. Longer waits for payment. Requiring claims to be reopened between 2025 and 2028 postpones payment. People who have already waited years may face further delays of several years depending on the tax year claimed; for example, a refund for 2022 is claimed in 2028.

3. Additional administrative complexity. Replacing the old form with a separate annual procedure creates extra work for taxpayers and potentially for the Tax Agency. Mutualistas also fear confusion when resubmitting claims that were already documented and filed.

4. Appeals and administrative claims. A mutualista who appealed a rejected correction request may also be affected by cancellation of the original application. Although the law interrupts the limitation period, it does not immediately clarify whether the appeal should be closed and a new claim opened.

5. Diverging interpretations and legal certainty. Different interpretations may arise in unusual cases, such as where the Agency issued a request for information but has not made a final decision, or where verification is still under way. Tax adviser groups and professional associations have called for greater legal certainty and clearer rules.

5. Practical consequences and recommendations

1. If the Tax Agency approved your refund before 22 December 2024: you will receive the refund and the file is closed; the change does not affect you.

2. If your application had not been approved and paid by 22 December 2024:

   • It will be cancelled automatically.

   • The application will nevertheless have interrupted the limitation period.

   • You will need to submit a new application using the new form in the relevant year (2019 in 2025, 2020 in 2026, and so on).

3. Follow the 2025–2028 calendar: submit a new refund request for each tax year during that year’s voluntary tax-return filing period. If you claimed several years, refile them in stages.

4. Keep your supporting documents: retain mutual society certificates, copies of earlier applications and notices. The same information may be needed for the new procedure, even if the previous application has formally lapsed.
