Appealing to Hacienda: TEAR/TEAC, rectification and binding rulings

There are 3 different instruments to deal with Hacienda outside of court. The economic-administrative claim (articles 226 to 249 of the General Tax Act) is used to challenge an act already issued: a settlement, a penalty, a denial of a refund or the result of an inspection. They are resolved by the Economic-Administrative Tribunals, which are independent bodies from the Tax Agency (AEAT).

The rectification of a self-assessment (article 120.3 of the General Tax Act) is used when you made a mistake in your favour: you declared too much, forgot a deduction or a withholding and overpaid. It does not challenge an act from Hacienda, it corrects your own tax return.

The binding written tax ruling (articles 88 and 89) is preventive: before acting, you ask the Directorate General for Taxes (DGT) what criteria Hacienda will apply to your case. The response binds the Administration. Managora identifies the correct route and processes it for you.

The economic-administrative claim is free (unless there is recklessness or bad faith) and does not require a lawyer or a procurador (court representative). It is filed within a strict deadline of 1 month from the notification of the act, through a written document addressed to the same body that issued it, which forwards it to the Tribunal along with the file. For those obliged to receive electronic notifications, the submission is online through the AEAT electronic headquarters.

The amount determines the procedure. Below €6,000 (or €72,000 in tax bases or valuations) the abbreviated procedure is followed, which is defined solely by the amount, with the written submissions (alegaciones) in the document itself and a resolution in 6 months. In this procedure the Tribunal itself (TEAR or TEAC) can resolve as a single judge, without this implying a different body or being mandatory. In the general procedure, the file is made available for written submissions (alegaciones), and the resolution period is 1 year.

If the Regional Tribunal (TEAR) dismisses the claim and the amount exceeds €150,000 (or €1,800,000 in tax bases or valuations), an appeal can be lodged before the Central Tribunal (TEAC). If it does not reply on time, you can consider it dismissed by silence and move on to the contentious-administrative route. Managora drafts the written submissions (alegaciones) and submits the claim for you.

When a self-assessment has harmed your legitimate interests (you overpaid or made a mistake in your favour), you can request its rectification as long as the right has not expired, meaning within 4 years. If the correction results in an amount to be refunded, Hacienda reimburses it, but late payment interest is not automatic: when it is an undue payment (article 32 of the General Tax Act) it is paid from the date of payment. When it is a refund derived from the tax regulations (article 31), such as an omitted withholding, it only accrues if 6 months pass without the payment being ordered. The resolution period is 6 months. If this passes without a response, it is considered dismissed by silence.

From the 2024 financial year, personal income tax (IRPF) is corrected with the rectifying self-assessment: a new tax return (Modelo 100) ticking the rectifying box, which replaces the old system of requesting a rectification plus a complementary return. For 2023 and previous years, the previous system of a written request remains in force. Managora calculates the difference and submits the rectification for you. The cost of our service is shown on the procedure page.

The written tax ruling allows you to ask the Directorate General for Taxes, before acting, what tax regime, classification or qualification corresponds to your specific case. It must be submitted before the deadline expires for exercising the right, submitting the tax return or self-assessment, or fulfilling the obligation in question.

The reply is binding for the tax application bodies: they must apply that criteria to any taxpayer provided there is identity between their facts and those of the ruling. The DGT has 6 months to reply. A lack of response on time does not imply acceptance of your criteria nor does it exempt you from complying. The reply itself cannot be appealed, but the subsequent act of application can be. Managora prepares the ruling with the appropriate legal approach and submits it to the DGT for you.

Before the Administration, all 3 routes are free: there is no tasa (official fee) to claim before the TEAR or TEAC, to rectify a self-assessment or to consult the DGT. Managora charges for preparing the document, providing the legal basis and submitting it for you. You can see the updated amount on the page for each procedure.

The Administration's processing times are stable: 6 months in the abbreviated claim procedure and 1 year in the general one. It takes 6 months to resolve the rectification of a self-assessment, and 6 months for the DGT to answer a ruling. The deadlines to submit (1 month for the claim, 4 years for the rectification) are strict, so it is advisable to act quickly.

Ley 58/2003, the General Tax Act, remains the current regulation for the 3 routes: binding ruling (articles 88 and 89), rectification of self-assessment (article 120.3) and economic-administrative claim (articles 226 to 249), in addition to the optional appeal for reconsideration (articles 222 to 225).

The relevant novelty is the rectifying self-assessment, introduced by Real Decreto 117/2024 and developed by Orden HAC/242/2025, in force since 15 March 2025. From the 2024 IRPF financial year, correcting the tax return is done through this single route instead of the previous dual system. For financial years prior to 2024, the previous system is maintained.
