Hacienda sends 130,000 letters

Spain’s Tax Agency is preparing to send about 130,000 preventive letters to taxpayers who may have made errors or left out information in their 2025 income-tax returns, according to campaign materials and reporting published during the first half of May. The agency said on May 6 that, as in the previous two years, it would start sending letters “in coming dates” to taxpayers over possible errors or omissions, while also posting alerts in Renta Web and in its mobile app. The letters are part of the annual income-tax campaign for 2025 income, filed in 2026. The filing window runs from April 8 to June 30, 2026, according to the Tax Agency’s campaign calendar, with June 25 as the last day to file if the result is tax due and the taxpayer wants to pay by direct debit. (europapress.es) The notices matter because they are not, by themselves, a sanction. They are an early warning that the agency sees a discrepancy between the return filed and data or criteria it believes should apply, and they give taxpayers a chance to amend the return before a later regularization. That framing appears in multiple reports citing the campaign rollout and in the agency’s own guidance on how to modify a return already filed. (sede.agenciatributaria.gob.es) ### Who is expected to receive these letters? The 130,000 figure has been cited in Spanish media reports on the campaign and aligns with the Tax Agency’s May 6 statement that preventive letters would begin going out shortly to taxpayers with possible errors or omissions. Europa Press, citing agency data on the first month of the campaign, said the letters would start being sent “in coming dates.” Other reports published between May 6 and May 16 put the volume at about 130,000 and said the mailings would be concentrated in May and June. (europapress.es) The agency has not, in the material accessible here, published a public list of recipients or a breakdown by type of discrepancy. Reports in Spanish outlets say the letters are aimed mainly at taxpayers who changed preloaded tax data or whose declarations show omissions or mismatches in items such as pensions, investment income or other reported earnings. Those details come from press reporting and should be read as such. (europapress.es) ### Does getting a letter mean there is already a fine? The answer is no. Multiple reports on the campaign say the letters are preventive notices rather than inspection findings or automatic penalties, and the Tax Agency’s published workflow for a filed return shows that taxpayers can still modify or complete a return through Renta Web. A taxpayer who receives one of these notices is being asked, in practice, to review the return and either correct it or be prepared to justify the figures used. (elespanol.com) If a return needs to be changed, the agency says the filer can use the “Modificar declaración Renta 2025 ya presentada” function in Renta Web and submit an “autoliquidación rectificativa,” or rectifying self-assessment. (merca2.es) ### How can someone tell whether the notice is real? The Tax Agency says taxpayers can consult and manage notices through its electronic-notifications services and through the DEHú system, the centralized state notifications portal. The agency’s site says DEHú access does not require creating a separate mailbox or prior registration, and its electronic headquarters also provides a search tool for notifications and communications linked to the taxpayer. (sede.agenciatributaria.gob.es) That matters because Spain’s tax campaign is also a phishing season. Prosegur Cybersecurity said this month it had detected a significant increase in phishing and smishing campaigns impersonating the Tax Agency in order to obtain personal data, login credentials or banking information. (sede.agenciatributaria.gob.es) ### What should a taxpayer do after receiving one? The first step is to compare the filed return with the taxpayer’s fiscal data and supporting documents. The Tax Agency’s guidance says a filed Renta 2025 return can be modified online, and the system carries over key information from the original filing to reduce calculation errors. (servimedia.es) The second step is timing. June 30, 2026 is the end of the Renta 2025 campaign, and June 29 is the last day to request an appointment for phone or in-person assistance, according to the campaign calendar. The broader campaign is large. The Tax Agency expects 25.25 million returns in the 2025 campaign, with 62.2% of them resulting in refunds worth an estimated 13.271 billion euros, agency officials said at the campaign launch in April. (sede.agenciatributaria.gob.es) For taxpayers who receive a notice in the next several weeks, the immediate next steps are already fixed: online filing remains open through June 30, phone assistance runs through June 30, and in-person office assistance is available from June 1 through June 30 by appointment.
