Tax Deductions for Dental Expenses in Spain: A 2026 Guide

Dental care can be a significant expense, but residents of certain Spanish autonomous communities may be able to recoup some of those costs when filing their 2026 income tax return (corresponding to the 2025 fiscal year). The Agencia Estatal de Administración Tributaria (Spanish Tax Agency) confirms that several regional deductions for oral health expenses remain in effect. These deductions can result in refunds of up to €840 in favorable cases.

Where You Can Deduct Dental Expenses and How Much

The availability and amount of these tax benefits depend on the autonomous community and the taxpayer’s income bracket. Currently, the following regions offer deductions:

• Canary Islands: Allows a deduction of a percentage of non-cosmetic dental expenses, capped at €600 for individual filers and €840 for joint filers, subject to income requirements.
• Cantabria: Offers a 10% deduction on healthcare expenses, including dental treatments, with limits of €500 for individual filers and €700 for joint filers.
• Valencian Community: Provides a 30% deduction on health expenses, including non-cosmetic dental care, but with a lower maximum deduction amount.

Specific amounts and income thresholds are determined by regional regulations and may vary based on family situation and income level.

Key Requirements for Claiming the Deduction

Simply paying for dental treatment isn’t enough to qualify for the deduction. Several formal conditions must be met:

• Complete, Itemized Invoice: A detailed invoice issued in 2025, clearly identifying the patient and services rendered, is required.
• Non-Publicly Funded Expenses: Expenses must not be covered by the public healthcare system or private insurance.
• Traceable Payment Method: Payment must be made via traceable methods such as credit/debit card, bank transfer, certified check, or bank deposit. Cash payments are not accepted.
• Income Limits: Taxpayers must respect the income limits established by each autonomous community.

The deduction is claimed in the autonomous community deduction section of the income tax return during the spring 2026 filing season.

Why This Matters

Dental treatments are a common household expense. This regional tax deduction provides a direct way to reduce your tax burden, particularly for families with multiple members or those undergoing extensive dental work.

If you paid for dental care in 2025, it’s crucial to retain all documentation and review the regulations in your autonomous community. You may be eligible for a refund.
