Spain's tax agency updates Renta Web with missing regional deductions

Hacienda patches Renta Web: the regional deductions missing at the start of the tax season

The Agencia Tributaria (Spain's tax agency) has released a new version of Renta Web for the 2025-2026 tax season, adding regional deductions for the Valencian Community and Castilla-La Mancha that were not available when filing peine. According to sources at the agency, taxpayers in these regions can now apply the deductions, but must do so manually through the 'Other deductions' section. A half-way patch that forces citizens to keep an eye on what Hacienda leaves out.

The 'oversight' on deductions that could save you hundreds of euros

The problem is no small matter: regional deductions for municipalities at extreme risk of depopulation, among others, can make the difference between a tax return that requires payment and one that results in a refund. The fact that they were not included from the start forces those affected to amend their draft return or, worse still, having filed without knowing they were losing money. The question is: how many taxpayers have already filed without these boxes and will now have to modify their return?

Refunds arrive when Hacienda feels like it

Meanwhile, the tax season is producing cases of refunds that are slow to arrive. A taxpayer who filed on 28 April is still waiting for 800 euros more than two months later. Hacienda has until 31 December to pay without interest, but the disparity is striking: while some receive their money within weeks, others wait months. The official line is that reviews of self-employed professionals or large amounts delay payments, but practice shows the system is arbitrary. Or, as some put it, Hacienda is quick to collect and slow to pay.

In the end, the tax season leaves two lessons: always check the regional deductions even if Hacienda ignores them at first, and don't assume your refund will arrive soon. As always, the taxpayer who is best informed loses the least.
