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.

The cover carries a single carved letter: Ñ. It is the only character in the Spanish alphabet that belongs to no other language. It is what Spain asks you to add to your own name, your own status, your own paperwork, before it lets you work legally on its soil. The playbook teaches you how to carve it.

🗂️ What This Playbook 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 order is not arbitrary. It mirrors the sequence of the compliance cycle.

The autónomo-to-SL decision tree. The 60,000 € figure you read elsewhere is a dangerous simplification. The real threshold depends on one variable most guides ignore: how much profit you must extract to live.

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 crypto-fiat bridge. Invoicing in stablecoins or BTC. The EUR conversion source that survives audit. The VAT place-of-supply table. The Beckham Law and Modelo 721 intersection. Four gray zones flagged explicitly, with modeled consulta vinculante questions in Spanish legal register.

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. General base for activity income. Savings base for crypto gains.

The gestor protocol. The seven-question vetting grid. The responsibility allocation that survives an AEAT review. The exit clause.

The AEAT audit defence. Four procedures and their clocks. Four crypto-specific triggers: the DAC8 cross-matching gap, the Modelo 721 omission, DeFi classification inconsistency, permuta valuation gaps. The written-only response principle. The conservative-basis rule.

Exit and migration. Status changes. Residence changes. The exit-tax question under Article 95 bis LIRPF.

Appendix C
Consulta Vinculante Bibliography

How to file a binding opinion with the DGT. Five modeled questions in Spanish legal register.

Do I need to own crypto to buy this playbook?

Layers 1, 2, 4, and 5 apply to any autónomo. Layers 3, 6, and the second half of 7 assume part of your income arrives in stablecoins, BTC, or ETH. If you invoice only in fiat, read the fiat-relevant layers and skip the rest.

Is this the same as the Source of Funds Dossier?

No. The Dossier teaches you to prove the origin of accumulated crypto wealth to a banker. This playbook structures your ongoing activity: registration, invoicing, filing, defence, exit. The Dossier is for the mountain already climbed. The playbook is for the road ahead.

What is a gray zone, and why are there five?

A gray zone is a point of Spanish tax law where doctrine is unsettled and no binding consulta vinculante from the Dirección General de Tributos has decided the question. Five such zones apply to a crypto-active autónomo: crypto-denominated invoice conversion (G1), yield-bearing token accruals (G2), VAT on DeFi liquidity (G3), Beckham and Modelo 721 subjective scope (G4), and equity-like tokens at exit (G5). For each, the playbook provides a modeled question ready to submit through the AEAT portal.

Does this cover the Beckham Law?

Layer 3.3 covers the regime under Article 93 LIRPF and its intersection with Modelo 721. G4 flags the unsettled question of whether Beckham taxpayers fall within the Modelo 721 subjective scope. The scout’s rule: over-declare at zero cost, or obtain a consulta vinculante before filing.

How long is the playbook?

61 pages. Seven layers. Eleven printable templates. Five gray zones. The playbook is executed, quarter by quarter.

Can I read it before I move to Spain?

Layer 1 and Layer 2 are written to be read before you register. Layers 3 through 7 apply from the day you file your Modelo 036. If you are still deciding whether Spain is the right jurisdiction, read Before You Land first.
