Our editorial policy

Factivo guides help self-employed people in Spain organize documents, invoices and administration.

Sources and review

News helps us identify relevant questions. We consult official sources such as Agencia Tributaria, BOE and Seguridad Social to check rules, requirements and dates. Drafts are published after human review or, when autopilot is enabled, after online research and a second AI verification. We identify automated reviews and show consulted sources. Automated checks can still miss errors.

Use of AI

We use AI to suggest topics and prepare drafts. AI does not establish professional expertise or replace source review. These guides are not personalized tax advice.

Corrections and updates

If you spot an error or a changed rule, send us the article and supporting source. We update the review date when the content is checked and approved again.
