Every year, when the tax return season arrives, many people and companies wonder which costs they can deduct. Language training is one of the most common questions, particularly for those investing in improving their own professional profile or that of their teams.
In this article we explain clearly when English or other language classes can have a tax impact in 2025, what requirements you must meet and how to make the most of these possibilities without making mistakes.
Can language classes be deducted in your tax return?
The short answer is: it depends on the case.
In Spain, training costs are not generally deductible for private individuals, but they can be in certain very specific situations. The key lies in the relationship between learning the language and the economic or professional activity.
Cases where they can be deducted
- Self-employed workers: can deduct the cost if the language training is directly related to their activity.
Example: a consultant who works with international clients and needs to improve their business English. - Companies: can deduct employees’ language training as an expense if it is linked to the running of the business.
Example: an exporting company that funds German classes for its sales team. - Subsidised training (FUNDAE): in many cases companies can fund language training through training credits with FUNDAE, the Spanish state foundation for workplace training.
Cases where it is not usually deductible
- Private individuals studying languages out of personal interest.
- Students with no economic activity.
- Training unrelated to the professional activity.
What requirements you must meet to deduct these costs
Paying for a language course is not enough: Hacienda (the Spanish tax authority) requires certain conditions to be met.
A direct link with the activity
The language must be necessary to carry out your job or run your business. The more obvious that link, the lower the risk in a possible review.
A practical example:
A lawyer starting to work with foreign clients has a clear justification for deducting legal English classes.
Documentary evidence
You must keep:
- Full invoices (with the correct tax details)
- Proof of payment
- Contracts or documents evidencing the activity
Accounting records (for the self-employed and companies)
The cost must be correctly reflected in the accounts or in the official record books.
Differences between freelancers, companies and employees
Not every profile has the same tax options.
Self-employed workers
They have the widest scope to deduct. As long as the course is linked to their activity, they can include it as a deductible expense.
Companies
Companies can:
- Deduct the cost of the training as an expense
- Access subsidies through FUNDAE
- Improve the team’s skills without increasing real costs
Employees
Generally they cannot deduct language classes directly in their return, except in very specific situations (such as certain regional deductions).
Are there regional deductions?
Yes, some comunidades autónomas (Spain’s regional governments) provide education-related deductions, although they tend to focus on:
- School costs
- Languages within compulsory education
- Formal education
They do not usually apply to adult language courses outside the official education system, but it is worth checking each region, as the rules can change.
How to make the most of language training for tax purposes
Beyond the direct deduction, there are smart ways to optimise this type of investment.
For companies
- Commit to subsidised training
- Build languages into the talent development plan
- Justify the training as a productivity improvement
For freelancers
- Choose courses aligned with their actual activity
- Document the professional use of the language
- Work with language schools that issue full invoices

Common mistakes to avoid
Most problems with Hacienda come from small oversights. These are the most frequent:
- Deducting courses unrelated to the activity
- Not having a valid invoice
- Paying in cash with no receipt
- Not recording the expense correctly
A preventive approach is always the best strategy.
Why investing in languages still pays off
Even where there is no direct tax advantage, language training remains one of the most profitable investments:
- It improves employability
- It makes going international easier
- It increases business competitiveness
- It opens access to new markets
Strategically, the return usually goes far beyond the tax saving.
Frequently asked questions
In most cases, no. It would only be possible in very specific situations or where a particular regional deduction exists.
Yes, provided they meet the same requirements as in-person classes: a link with the activity, a valid invoice and proper supporting evidence.
If you can demonstrate the link with your activity and all your paperwork is in order, there should be no problem. The key is consistency and a clear audit trail for the expense.
Deducting language classes in your tax return is not automatic, but it is possible in certain contexts, particularly for freelancers and companies. Understanding the requirements and documenting the cost properly is what makes the difference.
