From MiCA regulation to Modelo filings — answers to the questions compliance officers, traders, and CASPs ask most.
MiCA (Markets in Crypto-Assets Regulation) is the EU's comprehensive regulatory framework for crypto-assets. It establishes uniform rules across all 27 member states for the issuance, offering, and provision of services related to crypto-assets. MiCA requires all Crypto-Asset Service Providers (CASPs) to obtain a license and comply with operational, disclosure, and reporting obligations.
MiCA full enforcement begins on July 1, 2026. Title III and IV (covering asset-referenced tokens and e-money tokens) have been in effect since June 30, 2024. After July 1, 2026, any CASP operating in the EU without a MiCA license commits a criminal offence. Fines can reach up to €5 million per violation.
MiCA defines three categories of crypto-assets: Asset-Referenced Tokens (ARTs) — tokens pegged to multiple assets like commodities or currencies; E-Money Tokens (EMTs) — tokens pegged to a single fiat currency (e.g., USDC, USDT); and Other crypto-assets — everything else including Bitcoin, Ethereum, and utility tokens. Each category carries different regulatory requirements.
Any entity providing crypto-asset services to EU residents needs a MiCA CASP license. This includes exchanges, custodial wallet providers, crypto-to-fiat and crypto-to-crypto trading platforms, portfolio managers, advisors, and entities involved in the transfer of crypto-assets. There is no grandfathering clause after July 2026 — all CASPs must hold a valid license.
DAC8 (Directive on Administrative Cooperation 8) is an EU directive mandating automatic exchange of crypto-asset transaction data between member state tax authorities. CASPs and intermediaries must report transaction details including amounts, asset types, settlement values, and counterparty information. The implementation deadline is September 30, 2027.
Modelo 721 is a Spanish tax declaration form for crypto-assets held abroad. If you are a Spanish tax resident and hold crypto-assets on foreign platforms with a total value exceeding €50,000, you must file Modelo 721 annually with the AEAT (Agencia Tributaria). The filing deadline is March 31 each year for holdings as of December 31 of the previous year.
Modelo 172 reports crypto-asset balances held by third parties — platforms and custodians must file this to declare client holdings. Modelo 173 reports crypto-asset transactions performed through intermediaries — every buy, sell, swap, and transfer must be declared with EUR equivalent values. Both require machine-readable XML schema submissions to AEAT.
Modelo 721 is due by March 31 each year. Modelo 172 and 173 annual filings are also due by March 31 for the preceding fiscal year. SENTINEL tracks all deadlines and sends priority alerts as they approach — so you never miss a filing window.

No. SENTINEL provides compliance tooling, not legal advice.
