“Many People Lose Money on Their Tax Return Simply by Not Checking a Box”
The deadline to file Spain’s 2025 tax return (for the 2024 fiscal year) is June 30. With fiscal changes and new digital tools, this year’s campaign presents opportunities to optimize your return and avoid paying “a single euro more than necessary,” says Miriem Diouri, founding partner of MDG Asesores and expert in tax planning.
One of the most common mistakes? Not taking advantage of all available deductions. “Many people lose money simply by not checking a box,” Diouri explains. Deductions related to having children, paying rent, or making donations can significantly increase your refund — as can regional tax benefits, which vary depending on the autonomous community.
Additionally, contributions to pension plans can reduce your taxable base by up to €1,500 — or more if the contributor is a low-income spouse — making them especially valuable for those with medium or high incomes. While this is a deferred benefit, it can lead to substantial tax savings over time.
If you sold stocks, cryptocurrencies, or property at a loss, remember to declare those losses to offset current or future gains. Many people forget this and lose the opportunity to lower their tax bill.
Both employees and self-employed workers can claim specific reductions for work-related or economic activities. For freelancers, every deductible expense — from mobile phone bills to home office supplies — counts toward reducing their taxable income.
Deductions for maternity, large families, or disabilities can also add up to €1,200 and can be received in advance or claimed in your return. Even if you didn’t request the early payment, you can still claim it now — as long as you check the right boxes and provide the necessary information.
Finally, Diouri warns that the draft return provided by the Spanish Tax Agency (Hacienda) doesn’t always include all deductions or personal data. She recommends reviewing it carefully and, if possible, consulting a tax advisor to maximize your savings. “Thousands of taxpayers accept the draft without checking it and end up losing money,” she concludes.
