Why this manual exists
You are a freelancer. Your clients pay in stablecoins. You are about to register, or you have just registered, as an autónomo in Spain. Every free guide you have found stops exactly where your problems begin.
What this guide solves
The seven layers. Stress Test, Sequence Logic, The Crypto-Fiat Bridge, Cash-Flow Calendar, Gestor Protocol, AEAT Audit Defence, Exit and Migration. Each layer answers a specific question the Spanish tax authority and the Seguridad Social are legally required to ask.
The IAE epígrafe selection. The code that decides your quarterly cash flow. Professional epigraphs carry 7%/15% withholding. Business epigraphs carry none, but require Modelo 130 prepayments instead.
The RETA regularisation trap. The January and February bill that hits first-year autónomos. The provisioning formula: 28% to 35% of gross. Two bases, two rates. Chapter 4 walks both.
“The harbour master does not fear the ship with clean papers.”
