The countdown is over. Although the official calendar of the Tax Agency marks the start of the campaign on April 8, 2026, Spanish taxpayers already have the key in their hands to anticipate the treasury.
Since these last weeks of March, access to tax data has allowed millions of citizens to resolve the question that generates the most insomnia: is it time to declare this year?
Check your data now
The tax advisor @PituTax assures that “you can now know if you are obliged to file the Income Tax Declaration.” And access is as simple as entering the electronic headquarters of the AEAT, identifying yourself and reviewing the history of income, properties and aid for the year 2025.
Not all citizens have to check out. Article 96 of Law 35/2026 establishes clear limits. If you have only had one payer, the threshold is 22,000 euros per year. However, if you have had two or more payers and the second exceeds 1,500 euros, the limit drops drastically to 15,876 euros.
What happens with the draft and freelancers
Unlike employees, the self-employed group has no room for maneuver. Self-employed workers registered with the RETA are obliged to declare, in any case, regardless of whether their income has been high or minimal during the last year.
If the tax data leaves you with doubts, there is an infallible tool. As the specialist explains, “if you want to get ahead and know now if you are going to pay or return, you can enter the 2025 web income simulator, fill out the simulator with your data and you will have the draft done.”
This option allows you to know the result without any commitment before the official deadline to submit the Income Tax opens. However, you must be careful with this method, since the Treasury receives information from platforms such as Airbnb, Wallapop or Vinted, among others under the DAC7 directive.
To enter the electronic headquarters and download the PDF with the tax data, you can use the Digital Certificate, the electronic DNI, the Cl@ve system or the reference number (using box 505 of the previous income tax).
