What Changes in 2026: DAC8 and Global CARF Reporting

DAC8 (Directive EU 2023/2226) launches an EU-wide crypto tax reporting framework: from January 1, 2026, amendments to administrative tax cooperation extend information exchange to crypto platforms (CASPs). EU-registered providers will collect standardized client/transaction data for the 2026 tax year to pass to tax authorities.

In parallel, G20/OECD countries are rolling out CARF (Crypto-Asset Reporting Framework): 58 jurisdictions have announced first automatic exchanges in 2027 (covering periods starting in 2026). This raises the odds of cross-checking returns and visibility of on-/off-chain flows.

What This Means for Investors

Tax authorities will receive more data from exchanges/custodians → fewer “grey zones.”
Errors in your records (cost basis, dates, transfer network) will be more obvious.
It’s important to clean up your records in advance (see checklist below).

MiCA 2025: Why Compliance Affects Taxes

While MiCA is market regulation (not a tax code), its application to providers (CASPs) from December 30, 2024, plus ESMA guidelines in 2025, standardizes KYC/reporting and market-abuse controls.

The European Commission has adopted RTS on market abuse, and ESMA has published final guidance on prevention. Practically, this means more uniform data exports and fewer discrepancies between platforms.

Getting Data Ready for Tax Season 2026

1) Cost basis & calculation method

Choose a method (commonly FIFO, sometimes LIFO/average—country-dependent). Document it and apply consistently.

2) Transaction calendar

Export CSV/statements for 2025–2026: deposits/withdrawals (network: TRC20/TON/ETH/L2), trades, conversions, fees, addresses and TX hashes.

3) Income classification

Staking/lending/referral bonuses — usually taxable income upon receipt;
Airdrop/claim — often other income;
Mining/validating — income, then capital gains when you sell;
NFTs — sales may create a capital gain; account separately for fees/royalties.

Exact treatment is country-specific—follow your local tax authority’s guidance.

4) On-/off-ramps & fiat conversions

Keep bank statements/payment references, especially for P2P/instant-payment channels. Separate personal and business accounts.

5) Supporting documents

Store: order IDs, wallet addresses, screenshots of transaction details, contracts/invoices (if any business activity), platform reports.

Nuances People Often Miss

Stablecoins & RWA

Stablecoin operations (USDT/USDC/EUR-stablecoins) can trigger taxable events when sold/converted to fiat. For RWA tokens (tokenized treasuries), track interest income and FX results (EUR⇄USD).

DeFi & Token Allowances

Bridges/aggregators and “repackaging” liquidity (LP tokens) — record entry/exit points so you can compute basis correctly.

No Single EU-Wide “Wash-Sale Rule”

Wash-sale restrictions aren’t harmonized at the EU level—check national law.

DAC8/CARF: How the Reporting Will Look Like

In 2026, EU CASPs will start collecting standardized datasets (client identification, transaction amounts, addresses/networks, fees) for DAC8 exchange; the supra-national CARF aligns formats across participating countries, with first automatic exchanges in 2027. Expect more “matches” between your return and provider data.

How to Lower Your Tax TCO in 2026

Standardize your bookkeeping: one master ledger for all platforms.
Address mapping: label which addresses are yours (and tied to which exchanges).
Network/exchange fees: don’t lose them in your records.
Timing: mind FX (EUR⇄USD) effects and your country’s filing deadlines.

Country Cheat Sheet

There’s no single EU crypto tax code: timelines/rates/rules vary (DE, FR, ES, IT, etc.). Check:

filing deadlines and forms (some countries have dedicated capital-gains schedules),
withholding on interest/coupons (for RWA/income streams),
staking/airdrop rules (income vs capital),
currency accounting (EUR base vs USD operations).

FAQ

Do I need to file if I “never withdrew” to a bank?
In most countries, the taxable event is disposal (sell/swap/spend), not the bank withdrawal. Check local rules.

Will DAC8 affect my 2026 taxes?
Yes: providers will collect 2026 data for exchange among EU tax authorities; clean records matter more.

When do CARF exchanges start?
First automatic exchanges are expected in 2027 across 58 jurisdictions.

Does MiCA change tax rules?
Not directly, but it raises market/reporting standards at CASPs (including market-abuse controls), which indirectly improves tax data quality.

Bottom Line

DAC8 expands crypto data sharing, CARF sets up cross-border exchanges in 2027, and MiCA raises process standards at providers. To hit the new tax season calmly, maintain a unified trade log, classify incomes in advance (staking/airdrop/NFT), calculate your tax TCO, and verify your country’s specifics.
