Going to the dentist can represent a significant expense throughout the year, but in some cases it can also become a way to pay less on the Income Tax return. The Tax Agency has confirmed that there are regional deductions that allow recovering part of that money, provided certain requirements are met.
It is not a general measure throughout Spain, but rather tax benefits applied by some autonomous communities in the autonomous section of the Personal Income Tax (IRPF). In them, taxpayers can include certain health expenses, among them dental ones, and thus reduce their tax bill.
How much money you can save on Income Tax
Savings depend on the community in which the taxpayer resides, but in the most favorable cases, they can reach significant figures.
Specifically, some regions allow deducting up to 15% of dental expenses, with a limit that can reach 840 euros annually, provided that the established requirements are met.
It is a deduction that, in practice, can make the difference in the final result of the declaration, especially in households with several members or prolonged treatments.
The communities where you can apply this deduction
Currently, two of the communities where this deduction has greater impact are:
- Cantabria: allows deducting 15% of medical and dental expenses, with a cap that can reach 840 euros depending on the income level
- Canarias: also includes deductions for healthcare expenses, among them dental treatments
These measures respond to a regional strategy to alleviate healthcare spending that the public system does not cover, especially in areas such as oral health.
What conditions you must meet
To be able to apply this deduction, it is not enough to have gone to the dentist. It is necessary to meet a series of formal requirements that the Tax Agency reviews carefully.
Among the main ones:
- The payment must have been made by electronic means (card, transfer or check)
- It is mandatory to keep the complete invoice for the treatment
- The expense must be correctly identified and linked to a healthcare professional
- The income limits established by each community must not be exceeded
The non-compliance with any of these points may prevent applying the deduction.
One of the most important requirements is the form of payment. The Treasury does not admit cash payments for this type of deductions.
The objective is twofold: on the one hand, guarantee the traceability of spending; on the other, reduce the underground economy in sectors where the use of cash has been habitual.
Therefore, having bank statements is essential to be able to include these expenses in the declaration.
The cost of dental treatments continues to be one of the highest for many families, as it is not generally covered by the public system.
These regional deductions seek to partially compensate that expense and facilitate access to healthcare.
Additionally, they encourage taxpayers to correctly declare these services, strengthening fiscal control.
When it is applied in the Income 2026
This deduction can be applied in the 2026 Income Tax campaign, which starts on April 8 and ends on June 30.
Taxpayers must include the expenses incurred during 2025 and check in their draft if they meet the requirements to benefit from this tax incentive.
Despite its impact, many people are unaware that they can include this type of expenses in their declaration.
Reviewing this point before confirming the draft can mean a significant saving without the need to carry out any additional management, beyond having saved the corresponding documentation.
