MRR Fund Reimbursement 2026: What Recovery Plan Recipients Must Do

Key data

Entities receiving funds from the Recovery and Resilience Mechanism (MRR) that did not execute spending or fully or partially failed to meet committed objectives are obligated to return those funds to the Public Treasury. The Order HAC/580/2026, of June 9, published and in force since June 10, 2026, regulates exactly how this reimbursement process is structured.

This regulation is not a warning: it is the definitive closure procedure. With the Recovery Plan coming to an end in 2026, the Ministry of Finance has established the rules of the game for recovering unjustified funds. If your entity received transfers linked to the Plan and there are doubts about spending justification or milestone compliance, the time to act is now.

What does this regulation establish?

Order HAC/580/2026 develops the procedure for reimbursement to the Public Treasury of Recovery and Resilience Mechanism (MRR) funds in the following cases:

• The recipient entity did not execute spending linked to the funds received.
• The entity fully or partially failed to meet the objectives committed in the transfer instrument.

The procedure is structured around two key accreditation documents:

When the transfer instrument does not provide for its own reimbursement procedure, the General Subsidies Law applies supplementarily. This is relevant for private entities that received MRR funds without a specific contractual framework regulating the return.

The regulation expressly excludes the REACT-EU mechanism, which has a different financial architecture and therefore a different reimbursement regime.

Economic and operational impact

The impact of this regulation is not measured in a single figure, but in the reimbursement risk assumed by each entity according to its execution level and objective compliance. The operational effects are immediate:

• Risk of total or partial reimbursement of funds received if compliance is not accredited through the provided certificates.
• Need to review supporting documentation of all projects financed with MRR funds before the Plan closure in 2026.
• Supplementary application of the General Subsidies Law when the transfer instrument does not contemplate its own procedure, which may imply additional timelines and consequences for private entities.
• Legal certainty for the closure process: the regulation also benefits entities that have complied, by clarifying exactly what documentation accredits compliance and closes the file.

The context is decisive: the Recovery Plan is scheduled to close in 2026. This means that the deadlines for regularizing non-compliance or partial execution situations are very short. Failing to act now is equivalent to assuming the risk of forced reimbursement.

Who does it affect?

Order HAC/580/2026 affects all entities that received transfers linked to the Recovery Plan with MRR funds:

• Autonomous Communities that received MRR funds to execute projects in their territories.
• Local corporations (municipalities, provincial councils, island councils) receiving Plan transfers.
• Public bodies (agencies, public business entities, public sector foundations) that managed MRR funds.
• Private entities that received transfers linked to the Recovery Plan, either directly or through specific calls.

Entities whose financing comes from the REACT-EU mechanism are expressly excluded, as it has its own reimbursement regime.

Practical example

A private company received an MRR fund transfer linked to a digitalization project with a specific objective: implement a management system within a determined timeframe. Upon reaching the Plan closure in 2026, implementation was only partially completed.

In this case, the entity must provide a current value certificate that accredits the spending actually executed. The amount not justified through that certificate must be reimbursed to the Public Treasury following the procedure of Order HAC/580/2026. If the original transfer instrument did not provide for its own reimbursement procedure, the General Subsidies Law applies supplementarily, with the consequences this implies in terms of timelines and interest.

The same scheme applies to an autonomous community that received funds for an energy transition program and did not reach the committed milestones: it must accredit through compliance or current value certificate what part of spending is justified, and return the rest.

What should companies do now?

1. Identify all MRR funds received by your entity and the projects they were linked to, including the objectives and milestones committed in the transfer instrument.
2. Review the spending execution level and the degree of objective compliance in each project financed with MRR funds.
3. Determine which certificate applies: if compliance was total, prepare the compliance certificate; if partial, the current value certificate.
4. Review the transfer instrument to check if it provides for its own reimbursement procedure. If not, apply the General Subsidies Law as supplementary rule.
5. Act before the Plan closure, scheduled for 2026. Timelines are short and voluntary regularization is always preferable to forced reimbursement.
6. Consult with specialized advisory services if there is uncertainty about the compliance level or available supporting documentation, especially in the case of private entities.
