What if more has been improperly paid? Should we ask the Administration for a refund? When? Under what circumstances?

Clarify your doubts by consulting your particular case

If an amount was paid into the Treasury that was not due, or that exceeded the amount due, the taxpayer may seek its refund. A refund of an undue payment is distinct from a refund due under the rules of a particular tax, although the latter may also carry interest in the circumstances provided by law.

Under Article 221(1) of the Spanish General Tax Law, the right to a refund may arise, among other cases, where a tax debt or penalty was paid twice; where the amount paid exceeded the amount payable under an administrative assessment or self-assessment; where a tax debt or penalty was paid after the tax authority’s collection right had become time-barred; or where tax legislation otherwise provides. The relevant circumstances must be evidenced; an unfavourable payment alone does not establish a right to a refund.

How do you apply? If the undue payment resulted from a self-assessment, the taxpayer should request correction of that self-assessment under Article 120(3) of the General Tax Law and, where appropriate, the resulting refund. In other cases, the procedure for refund of undue payments applies. The application should identify the payment, explain why it was undue, provide available supporting documents and specify the preferred refund method. Depending on the case, the regulations also allow a person who bore a withholding, payment on account or tax charged to them to seek a refund, subject to the applicable requirements.

The right to request a refund is generally subject to a four-year limitation period. The starting date depends on the circumstances: it may be the day after the undue payment, the day after the decision declaring the underlying act wholly or partly improper becomes final, or another date specified in Article 67(1) of the General Tax Law. The period may be interrupted, among other things, by a documented action seeking a refund or correction of a self-assessment, or by the filing, processing or resolution of an appeal or claim. It therefore does not always run from the date of payment.

A refund includes the amount unduly paid and, where applicable, late-payment interest, which the tax authority must calculate without a separate request. As a general rule, interest accrues from the date of the undue payment until the date on which repayment is ordered, subject to statutory exclusions for delays not attributable to the tax authority.

For refund procedures initiated at the taxpayer’s request, the maximum period for notifying a decision is six months. If no decision is notified within that period, the application may be treated as rejected by administrative silence; an express decision may also be challenged through the applicable administrative remedies. The tax authority must issue a reasoned decision and, if it recognises the right, execute the refund.

If the administrative act that led to the undue payment has become final, a direct refund request is not sufficient. Where the relevant requirements are met, the taxpayer must seek review of that act through an applicable special review procedure under the General Tax Law or an extraordinary review appeal.
