In 2026, Spaniards will face notable changes in the income tax filing process. New rules introduced by the Ministry of Finance will directly affect tax amounts, submission deadlines, and the list of deductions. For many families and property owners, these changes will mean rethinking their usual approaches to managing income and expenses.
Starting April 8, taxpayers can submit their returns online via the Renta WEB platform. This requires a digital certificate, an identification number, or Cl@ve PIN. Filing online allows for quick review and adjustment of preliminary calculations and lets you send documents without visiting an office. According to RUSSPAIN, telephone filing will be available from May 6, but an advance appointment is required, which can be booked between April 29 and June 29. For those who prefer in-person service, Agencia Tributaria offices will open their doors from June 1, with appointments available from May 29.
New tax rates
In 2026, an additional tax bracket will be introduced for capital income. Those earning more than €300,000 per year from capital gains or dividends will pay 30%. For amounts up to €6,000, the rate remains at 19%. This change especially affects individuals with significant assets and investors whose income exceeds the set threshold.
Tax benefits related to environmental initiatives remain in place. For example, expenses for installing electric vehicle charging stations or purchasing electric transport are still eligible for tax deductions. In addition, government payments received due to natural disasters, such as DANA or forest fires, are not subject to taxation.
Deductions for charity donors
In 2026, the deduction amount has increased for those donating to non-profit organizations. Now you can claim back 80% of the first €250 donated, whereas previously the limit was €150. If the sum exceeds this threshold, the deduction rises to 40%, and for regular donations to the same organization, up to 45%. This measure is designed to encourage long-term support for charitable projects.
A new rule has been introduced for recipients of the Salario Mínimo Interprofesional (SMI): if annual income does not exceed €16,576, filing a tax return is not required. For individuals with one employer, the limit remains at €22,000. If income comes from two or more employers, the exemption threshold rises to €15,876. This change makes life easier for many workers, especially those who changed jobs during the year.
Lowering the tax burden
A special tax discount of up to €340 is available for workers with incomes just above the new thresholds. This benefit is gradually reduced and phased out at incomes above €18,276. The measure aims to support citizens with low to medium incomes, easing their tax burden.
Property owners renting out their homes will also face new conditions. For contracts signed after January 1, 2025, different levels of tax deductions will apply. If the property is located in a high-demand area and the rent is reduced by 5% compared to the previous year, the maximum deduction is 90%. If the apartment is rented for the first time to a young tenant (aged 18–35) or for social housing, the deduction is 70%. For recently renovated properties, it is 60%. In all other cases, the deduction is 50%.
Context and recent changes
In recent years, Spain has regularly adjusted tax regulations to address economic challenges and support social initiatives. In 2025, additional deductions were already introduced for families with children and benefits for investors in green technologies were expanded. Analysis by russpain.com indicates that such measures enable the government to respond flexibly to changes in household income and stimulate the development of priority economic sectors. Last year, special attention was given to supporting those affected by natural disasters and encouraging long-term charitable projects. These trends continue in the current campaign, as reflected in the new rules and rates.
