Deductible expenses for self-employed workers in Spain

Deductible expenses for self-employed individuals in Spain: what you can deduct and what you cannot

One of the greatest tax benefits of being self-employed in Spain is the ability to deduct expenses related to your professional activity. However, it is also one of the areas where the most mistakes are made… and where the Tax Agency pays the closest attention.

In this article, we explain which expenses you can deduct, what requirements they must meet and what is best to avoid, with clear examples. For more complex cases, you will find links to our detailed guides.

When is an expense deductible?

For an expense to be deductible in IRPF and/or VAT, it must meet two key conditions:

1. It must be necessary for your professional activity
2. It must be used exclusively for that activity

Simply put:

If this expense is necessary to generate income from your economic activity, it is deductible.

If you are unsure whether it is personal or professional, the Tax Agency will likely question it as well.

Thinking like the Spanish Tax Agency is usually the best filter.

The invoice: the essential requirement

In most cases, without an invoice there is no deduction.

For an expense to be valid, you need a complete invoice that includes:

• Invoice number and date
• Issuer details (name, NIF/CIF, tax address)
• Clear description of the product or service
• Taxable base
• Applied VAT

With a proper invoice you will be able to:

• Deduct the expense in IRPF
• Deduct the input VAT

⚠️ Important: without a complete invoice you will never be able to deduct VAT, even if the expense is real.

Are there deductible expenses without an invoice?

Yes, but they are the exception, not the rule.

Some common expenses deductible in IRPF even without an invoice include:

• Self-employed contributions (Social Security)
• Professional associations
• Insurance
• Bank fees and commissions

In other cases (public transport, taxis, occasional tickets), it is always advisable to request an invoice whenever possible. A receipt may work in some cases for IRPF, but it is not a guarantee in the event of a tax review.

Main deductible expenses for a self-employed individual

Self-employed contributions

• 100% deductible in IRPF
• One of the easiest expenses to justify

Office or workplace

• Office or coworking rent: deductible if used exclusively for professional purposes
• Working from home: you can deduct part of the rent in proportion to the square meters used for your business activity, provided that the rental contract does not explicitly prohibit conducting economic activity at your home address. You can also deduct part of utility expenses (internet, electricity, water, gas) up to 30% of the proportion of square meters used for the activity relative to the total size of the home

Equipment and technology

• Computers, printers
• Software, licenses, digital tools
• Office supplies

Transport and vehicle

• Public transport, tolls, parking for professional reasons
• Vehicle: proportional deduction according to professional use for some economic activities
• (criteria regarding vehicles evolve and should be reviewed each year)

Meals and travel expenses

• Meals and accommodation for professional reasons
• With daily limits established by the Tax Agency
• Electronic payment and an invoice improve justification

Training

• Courses, books and training directly related to your activity

Professional services

• Accounting and tax advisory services
• Lawyers, consultants, marketing services

Insurance

• Professional insurance
• Private health insurance (with annual limits)

Depreciation and financial expenses

• Equipment, furniture
• Interest and commissions related to the activity

Employees

If you have employees:

• Salaries
• Social Security contributions
• Employee training and travel allowances

Can fuel be deducted?

Yes, but not always and it depends on several factors.

• IRPF: only if the vehicle is used 100% for the activity (very specific cases such as professional transport).
• VAT: normally you can deduct 50% of VAT on fuel if usage is mixed, and 100% in specific activities.

It is one of the most frequently reviewed expenses by the Tax Agency, so it should be well documented.

Expenses that are generally not deductible

• Personal expenses without a clear link to the activity
• Everyday clothing
• Fines and penalties
• Personal leisure

Key requirements for the Tax Agency to accept an expense

To avoid problems:

• The expense must be linked to your activity
• You must have a valid invoice or supporting document
• It must be correctly recorded in your accounting
• It must not be a personal expense

Conclusion

Deducting expenses as a self-employed individual is not about deducting everything, but about deducting correctly. Understanding what the Tax Agency accepts and keeping orderly accounting makes the difference between peace of mind and future problems.
