Spain's tax season kicks off: what you need to know
April 8th marks the official start of Spain's annual income tax filing season – a date circled in red by millions. Forget the dry explanations; this year brings new nuances, potential benefits, and a few pitfalls to navigate. We’re breaking down what you really need to know.
Understanding the irpf and your obligations
The process, known as “Renta,” is how Spanish citizens regularize their financial standing with the Agencia Tributaria (tax agency) concerning the Impuesto sobre la Renta de las Personas Físicas (IRPF) – essentially, income tax. You’ll declare income, deductions, and withholdings from the 2025 fiscal year. Generally, those earning over €22,000 annually from a single employer, or €15,000 with multiple payees, are obligated to file. But even if you’re not legally required, it’s often worth the effort – you might be due a refund.
Key dates and deadlines: a quick guide
The digital filing window is now open. Here’s a timeline to keep in mind:
April 8th – June 30th, 2026: Online filing via the Agencia Tributaria’s electronic portal begins. This is the preferred method for most.
May 6th – June 30th, 2026: Telephone support becomes available, requiring prior appointment booking from May 29th to June 29th.
June 1st – June 30th, 2026: In-person assistance at Agencia Tributaria offices opens, also by appointment only.
June 25th, 2026: Deadline to submit declarations with payments due via direct debit.
June 30th, 2026: The official end of the tax filing period.
Appointments can be secured through the Agencia Tributaria’s electronic portal or by calling 91 535 73 26 / 901 12 12 24 or the dedicated Renta appointment line at 91 553 00 71 / 901 22 33 44.
Beyond the basics: what’s new this year?
The Agencia Tributaria isn’t actively hunting for fraud, but they are scrutinizing certain areas. The first thing most taxpayers should do is access their pre-filled declaration – available online since April 8th via digital certificate, electronic ID, Cl@ve system, or reference number. However, don't assume this draft is complete; it often omits information from rental income, capital gains, or regional deductions. Don’t blindly submit it.
This year brings a notable tax break for low-income earners. To combat the impact of salary increases on IRPF payments, Hacienda has consolidated a deduction of up to €340 for those earning the minimum interprofessional wage (SMI). Autonomos (self-employed individuals) remain obligated to file regardless of income, while those receiving unemployment benefits only need to file if their earnings exceed certain thresholds.
Watch out for these changes: digital assets and mobile payments
Hacienda is sharpening its focus on digital assets. With the full implementation of Modelo 721, the tax agency possesses detailed information on cryptocurrency transactions abroad. Any exchange or sale must be accurately reflected to avoid penalties. The increasing prevalence of Bizum for payments is also under closer inspection, particularly for autonomous workers.
And the perennial pitfalls? Forgetting secondary income sources, failing to claim eligible deductions, or submitting unreviewed drafts remain common—and costly—mistakes. Don't let a simple oversight wipe out potential savings.
The bottom line? A proactive approach, combined with keen attention to detail, is your best defense against an unexpected tax bill.
