The Crypto Payroll Playbook

Why this manual exists

A Spanish sociedad limitada pays a contractor in USDC. The invoice states USDC. The accounting entry states euros. The Modelo 190 will state euros. Three documents, two currencies, one operation. This manual closes the gap between the rail and the classification.

What this guide solves

The rail is not the operation. The tax system classifies the service contract, not the payment method. A USDC transfer and a SEPA transfer produce the same corporate tax obligation — what changes is the computation of the euro figure. Chapter 1 develops the distinction.

The dossier is the defense. Not the absence of scrutiny, but the presence of paper. The audit file is built before the question is asked, not after. Chapter 3 walks the seven-layer corporate dossier.

The position is documented, not silent. Where the DGT has not resolved a point, the manual presents the two defensible positions, identifies the position retained by the author, and states the reasoning. Chapter 2 walks the withholding tax debate.

“The harbour master does not fear the ship with clean papers.”

Questions before you buy

Is this manual for me if I pay contractors in euros?
No. The manual addresses crypto-denominated payments. If your contractors invoice in euros and receive euros via SEPA, the standard corporate compliance framework applies.
Does the manual cover the Beckham Law?
The manual covers corporate compliance for Spanish SLs. The Beckham Law is an individual tax regime and is covered in the companion volume Before You Land.
Do I need a Spanish tax advisor to use this manual?
Yes. The manual prepares you to have an informed conversation with a licensed advisor. It does not replace one. Every procedural reference must be verified against current AEAT guidance at the moment of use.
Does the manual cover DAC8 reporting for the company's own treasury?
Yes, in Chapter Three. The scope of the corporate secondary reporting obligation is not yet resolved in Spanish law — the draft Royal Decree is not final. The manual documents the three defensible positions.
