for the self-employedThe tax authority may review previous tax years. You can review them proactively first.
We examine one to four previous Spanish tax years: documents, filings, income, expenses, withholdings, ledgers and traceability. We identify inconsistencies, risks and potential regularisation needs so the next steps can be prioritised.

Why four years
The latest tax year may show the symptom, not the cause.
Article 66 of Spain's General Tax Law establishes a general four-year limitation period for certain rights. The starting point and any interruption depend on Articles 67 and 68, the tax, the tax year and the actions taken; each case always requires professional validation.
A shorter period may be appropriate
For a defined question, a comparison of two years or an already limited pattern.
If you choose fewer years than recommended, the form will ask you to expressly accept that limitation.
Preventive tax information
Regularising before or after an official notice is not treated in the same way.
Review identifies and organises information. It does not guarantee an outcome or replace an assessment of the tax, tax year, error and specific administrative situation.
Before an official notice
Article 27 of Spain's General Tax Law generally provides for a 1% surcharge plus a further 1% for each complete month of delay up to twelve months. After twelve months, the surcharge is 15% and late-payment interest is charged for the period after those twelve months. Where this regime applies, penalties that might otherwise have been imposed are excluded.
If an official notice already exists
The Article 27 rule does not apply. Tax due, interest and, depending on the case, a penalty may arise. Article 191 governs separate infringements and the outcome is not automatic: it depends on the facts and the applicable classification.

FREQUENTLY ASKED QUESTIONS
The essentials before reviewing the past.
Is the onboarding for ?
No. It is a standalone, one-off service and does not activate a monthly fee.
Why are four years recommended?
Because an issue visible today may originate in earlier tax years. It is a preventive period, not a promise that no risks exist.
Does it include corrections or regularisations?
No. The report may recommend them, but they are quoted and authorised separately.
What happens if I have an official notice or active deadline?
The case undergoes professional validation without an automatic charge. does not include management of the procedure and does not permit the Article 27 rule to be applied as though no official notice existed.
Does activate or replace onboarding?
No. is independent; any recurring service is assessed and contracted separately.
