Practical explanation of deductible expenses for self-employed workers in Spain and how to organize them for accounting.

Which expenses are deductible for self-employed workers

A deductible expense is usually an expense related to the economic activity, correctly justified, and recorded. The specific rule depends on the type of expense and each self-employed worker's situation.

Quick summary

For an expense to be considered deductible, it normally needs to meet three conditions:

  1. Be related to the activity.
  2. Be justified with an invoice or valid document.
  3. Be recorded in an orderly way.

Common examples

  • Professional tools and software.
  • Management, advisory, or accounting services.
  • Materials needed to work.
  • Travel expenses linked to the activity.
  • A proportional part of certain utilities in specific cases.

Common mistakes

Keeping only the bank transaction

The transaction helps prove payment, but it does not always replace the invoice.

Mixing personal and professional expenses

Separating expenses avoids doubts and makes accounting review easier.

Uploading documents late

Uploading documents near close can create rush and errors.

How Numonis helps

Numonis lets you centralize invoices, receipts, and supporting documents so your accountant can review before close and request information if something is missing.
