DAC8, crypto and LLC: keeping reporting under control

DAC8 brings automatic reporting to EU crypto exchanges. If you use a US LLC, wallets and US banking, Exentax maps the structure so every piece matches.

DAC8 is the piece that completes Europe's tax-information system in the crypto world. From today, all crypto-asset service providers in the EU are required to report to European tax authorities the information of their clients and operations, in line with the CRS model applied to traditional banking. If you hold crypto and reside in the EU, or you have a US LLC operating with crypto on European exchanges, this affects you directly.

For the operational companion to this overview, read which 2026 records to prepare for the first DAC8 exchange in 2027.

CRS 2.0, CARF and DAC8 for DAC8, crypto and LLC

DAC8 is not a standalone text: it is the European transposition of the CARF that the OECD adopted inside the integrated package with CRS 2.0. That is why the timetable and the scope of the crypto piece match the full package and not those of a stand-alone directive.

Official sources: OECD — CRS, OECD — CARF, EUR-Lex — Directive (EU) 2023/2226 (DAC8).

DAC8 and CARF move the reporting discussion from bank accounts into crypto-asset service providers, wallets, exchanges and taxable crypto events. That does not turn a US bank account into a European CRS account, but it does mean a crypto layer inside an LLC must be documented separately from ordinary banking. We unpack the broader privacy layer in CRS, CARF and US banking privacy for your LLC.

What DAC8 is

DAC8 is the eighth amendment to Council Directive 2011/16/EU on administrative cooperation in tax matters. Council Directive (EU) 2023/2226 of 17 October 2023 extends that cooperation to crypto-assets using the OECD's CARF as its reference. It applies from 1 January 2026, first covers the 2026 calendar year and requires the first exchange between authorities by 30 September 2027.

DAC8 is for crypto-assets what CRS / DAC2 is for bank deposits and what DAC7 is for digital platforms: mandatory client identification, standardized data collection, annual reporting to the national tax authority and automatic exchange with other authorities.

Spain will transpose DAC8 via amendment of the General Tax Law and complementary regulations, integrating with the existing Form 721 regime (informative declaration on crypto-assets held abroad, in force since FY2023).

DAC8 extends EU reporting to crypto-asset activity

• OECD: Crypto-Asset Reporting Framework (CARF), published in March 2023.
• EU: Directive (EU) 2023/2226 (DAC8), 17 October 2023; application 1 January 2026.
• EU Regulation 2023/1114 (MiCA - Markets in Crypto-Assets): regulation of crypto-asset service providers in the EU; defines who is required to report under DAC8.
• Spain: Order HFP/886/2023 (Form 721); DAC8 transposition law (in process).

Who is affected

DAC8 affects:

• Reporting Crypto-Asset Service Providers (RCASP): any crypto-asset service provider regulated under MiCA in the EU. Includes centralized exchanges (Binance Spain, Coinbase Europe, Bitpanda, Kraken EU through subsidiaries), crypto brokers, custodians, DeFi platforms with EU legal presence, regulated stablecoin issuers.
• Service users (clients): individuals and entities, resident anywhere in the world, whose data is reported to their jurisdiction of tax residence.

Unlike CRS, DAC8 has no de minimis threshold: any active client is reported regardless of balance or volume.

What is reported

The DAC8 dataset is granular by asset and transaction category, but it does not contain a universal 31 December balance field. The LLC should still keep a closing inventory to reconcile units, cost and ownership.

Schedule

• 1 January 2026: effective application in Member States.
• 2026: first full reportable year.
• During 2027: each provider files under the deadline enacted by its reporting jurisdiction.
• 30 September 2027: deadline for the first exchange between EU tax authorities.

How it affects an LLC owner with crypto

1. LLC with an account at a European exchange (Bitpanda, Coinbase Europe, Kraken EU): the RCASP identifies the LLC and, where relevant, its Controlling Persons. It reports the aggregated activity and transfers required by DAC8 to its competent authority.
2. LLC with account at US exchange (Coinbase US, Kraken US, Gemini): not subject to DAC8. The US is developing its own framework under the infrastructure act and Form 1099-DA, but automatic exchange with the EU is not at the same level. Data may arrive via bilateral request or via the future CARF network if the US adheres.
3. Self-custody wallets: they are not service providers and do not file the report themselves. Transfers between an exchange and a wallet can form part of the reported dataset, so ownership and purpose should be documented.

Interaction with Spanish Form 721

If you are a Spanish tax resident and you hold crypto-assets on foreign platforms:

• Balance at 31 December > €50,000: Form 721 informative return, filed between 1 January and 31 March of the following year.
• Balance at Spanish regulated exchanges (Bit2Me, etc.): no Form 721, but reported under domestic regime and, from today, via DAC8.
• DAC8 + Form 721 generate a double cross-check: data reaches the AEAT both from the RCASP of the exchange's country and from the taxpayer's own filing.

DeFi operations and self-managed wallets

DAC8 addresses the difficult question of DeFi and self-custody. The directive imposes obligations on regulated RCASPs, but DeFi protocols without identifiable headquarters or operator fall outside direct reporting. However:

1. The entry and exit of funds between regulated exchange and own wallet are reported.
2. DeFi protocols with frontend operated from the EU may fall under MiCA and, by extension, under DAC8.
3. The OECD and the EU are developing additional DeFi guidance.

In practice, on-chain records and provider data make transaction paths easier to reconstruct. For a well-run LLC, an orderly wallet and transaction inventory becomes a documentary advantage.

Build crypto traceability before DAC8 reporting

1. Maintain rigorous crypto bookkeeping. Per-operation tracking with EUR/USD value at the date of each operation, FIFO or specific identification per jurisdiction.
2. Declare correctly in your IRPF (Spain: capital gains and losses on transfers, savings tax 19-28%). Introduced in crypto and trading with LLC.
3. Review local obligations separately. DAC8 does not replace residence-country forms such as Spain's Form 721 where it applies.
4. DAC8 consistency. What exchanges report must match what you declare.
5. Structure design. Where crypto activity is material, an LLC can separate assets, contracts, wallets, treasury and providers inside a clear business architecture. Full framework in designing a solid international structure.

Three decisions that strengthen the operation

• Separate personal and business ownership. Each exchange, wallet and settlement account should match the legal owner of the funds.
• Preserve the complete history. Purchases, disposals, swaps, fees and internal transfers need consistent identifiers and valuations.
• Use the LLC as an operating structure. Contracts, activity, treasury and records should tell the same business story.

The operating point to keep in mind

DAC8 brings crypto activity into the European information-exchange framework. For an international LLC, the strong response is practical: choose providers deliberately, separate accounts and wallets, preserve complete records and coordinate the structure with its owners' residence.

Put DAC8 inside the real crypto reporting file

Crypto reporting needs more than a wallet list. Exentax coordinates the LLC, exchange or payment provider, source of funds, bookkeeping and residence position so the international operation remains clear, efficient and ready to scale.

What DAC8 actually changes for crypto holders inside the EU

DAC8 extends the EU's automatic exchange of information regime to

crypto-asset service providers. The model is distinct from bank-account

reporting under CRS: platforms identify their users, classify the assets

and report annual aggregates by transaction category and crypto-asset,

together with the transfers specified by DAC8.

This means the matching of platform-reported aggregates with the

holder's annual declaration becomes the baseline of any DAC8-era

crypto compliance plan. If the two reconcile, the report is again a

non-event.

Three real reconciliation patterns

A holder who used a single regulated EU platform for spot trading

ran a clean year because the platform's annual report mirrored the

trade history exported each January, which fed straight into the

home-country declaration. The DAC8 record arrived as expected and

matched.

A user with a mix of EU-licensed and non-EU platforms produced one

master ledger that consolidated all venues, then mapped each line

to its source. The DAC8-reported part was a slice of the master;

the rest was self-declared with the same rigour. The home tax

administration saw a single coherent number.

A long-term holder with custody on a regulated EU platform and a

small DeFi tail kept the DeFi tail as a separately documented

section. DAC8 captured the regulated portion; the DeFi section had

its own paperwork (wallet addresses, transaction proofs, fair

valuation methodology) ready to present if asked.

Mistakes to avoid in the new regime

• Ignoring the platform's user data update request. If your tax

residence on the platform is stale, the report will go to the

wrong country.

• Treating "platform reports it" as "I do not need to declare it".

The reverse is true: declare it, and let the platform report

match.

• Mixing personal and LLC-held crypto. Crypto held by the LLC sits

in a different reporting silo than personal crypto; mixing them

causes painful reconciliations.

• Disregarding cost basis. DAC8 reports gross flows; the home-

country declaration needs the basis to compute the taxable result.

Annual reconciliation checklist

• Refresh user data on every platform in January.
• Pull annual reports as soon as they become available.
• Reconcile platform totals to your master ledger by asset.
• Confirm cost-basis methodology is consistent year-on-year.
• Keep proofs for any non-DAC8 holdings (wallets, validators, etc.).

We treat DAC8 as a structural simplifier, not a complication. Once

the routine is in place, the year-end work shrinks rather than

grows.
