In 2026, Spaniards will face changes to the process for submitting the 2025 IRPF tax return. For the first time, phone appointments for the ‘Le Llamamos’ consultation program will only begin on May 6, pushing back familiar deadlines for those not ready to file online. This decision affects millions of taxpayers, especially the elderly and those who do not use the internet for official procedures. The new rules could lead to queues and additional pressure on support services, as well as alter the usual rhythm of tax campaign preparation.
From April 29 to June 29, you can book a telephone consultation. However, the final deadline for submitting your tax return is June 30, and for those paying by bank direct debit, the last day is June 25. These dates are critical for those relying on telephone assistance from specialists, as missing them could result in fines or loss of certain deductions.
Documents required for tax declaration by phone
To process your tax return by phone, you will need to prepare several documents. Mandatory items include the original DNI (national identification document) of the person making the appointment, as well as copies of the DNI for anyone included in the return. You will also need your bank account IBAN, and to prove your right to deductions, the cadastral references of all properties you own or use, including rented apartments. The IBI (property tax) receipt can help you quickly locate the necessary information.
If you are renting your home, you will need the landlord’s NIF (tax identification number) and details of rent payments made. Those paying a mortgage or who increased their loan for the home must have information about outstanding loan balances and insurance receipts ready. Donors are required to provide supporting documents for charitable contributions. Preparing these documents in advance speeds up the process and helps avoid mistakes in calculating your tax base.
Special cases and nuances
The agency reminds: when completing your tax return by phone, it’s important to have documents confirming income from employment, capital, rentals, as well as information about property sales or other assets ready in advance. If the taxpayer is registered with the Cl@ve system, you will need the mobile number specified at registration. Otherwise, you should obtain a reference number online ahead of time.
In recent years, tax campaigns in Spain have seen changes in deadlines and submission procedures. According to RUSSPAIN.COM, in 2025, many faced difficulties due to new digital processes and the need for extra identity verification. This has led to more requests to tax offices and increased demand for telephone consultations.
Key details and implications
The introduction of new deadlines and document requirements may affect the usual procedures for filing tax returns. For many residents, booking an appointment by phone is the only way to get assistance, especially if they lack internet access or have difficulties with electronic services. It is important to remember that missing deadlines or lacking necessary documents can lead to denied deductions or additional audits.
In this context, it is worth noting that changes in the tax system are often accompanied by reforms and new regulations, as was the case with the judicial system: a reduction in the number of unresolved cases in the courts of Spain became possible only after the introduction of new procedures and digitalization. Similar processes are now taking place in the tax sector, requiring citizens to be more attentive and ready for change.
In recent years, Spain has regularly updated the rules for submitting tax returns to simplify the process and reduce queues at offices. In 2024, for the first time, an online request became mandatory for most services, leading to a surge in support calls. By 2025, the focus shifted to digital identification and automated calculations, but many people still prefer phone consultations. These changes reflect a general trend toward digitalizing public services, though not all age groups and regions have been equally considered.
