The course is built on official sources: anything asserted in class must be traceable back to a rule or an official instruction. That matters in a profession where an error costs the client money and where citing a blog summary carries no weight in a dispute with the tax authorities.
Official sources
| Source | What it is used for |
|---|---|
| Agencia Tributaria — practical manuals on VAT, income tax and corporate tax, plus instructions for each return | The principal tax reference across both stages |
| Seguridad Social — the self-employed scheme, Import@ss and the RED system | Contribution and payroll modules |
| BOE — consolidated codes: tax legislation and the General Accounting Plan | Chart of accounts, statutes and tracking amendments |
| ICAC — accounting rulings | Complex or contested entries in the company stage |
| Registradores — the Commercial Registry | Filing annual accounts and legalising books |
One skill practised throughout the course is finding the current wording of a rule independently, rather than relying on last year’s notes.
Tools

Professional bodies
AECE (the association of accounting and tax experts), REAF at the General Council of Economists, and the professional association of administrative agents. These serve as a source of tax news and as a professional network after the course.
