Deductible Expenses for the Self-Employed 2026: A Complete Guide with Real Examples

#The Inconvenient Truth: You’re paying more taxes than you should

Sixty-three percent of self-employed people in Spain don’t deduct all the expenses they could. And that means one thing: you’re paying more IRPF than necessary.

It is not your fault. The Spanish tax system is complex, information is scattered, and no one explains to you clearly what you can deduct and what you can’t.

This article teaches you exactly what expenses are deductible in 2026, with real examples and concrete percentages.

#⚠️ Basic concepts you need to understand

#What is a deductible expense?

An expense is deductible when it meets these 3 conditions:

1. It is related to your economic activity
2. Is correctly justified (invoice or ticket with your data)
3. Is registered in your accounting

#Why does it matter to deduct expenses?

Because it reduces your taxable income, i.e., the profits on which you pay personal income tax.

Example:

• Annual income: 40.000€
• Deductible expenses: 10.000€
• Taxable income: 30.000€ (instead of 40.000€)

Result: You pay income tax on 30.000€ instead of 40.000€. Approximate savings: 2,000-3.000€ per year.
