What EU Crypto Firms Must Know Now

By 2026, MiCA-compliant DeFi protocols could face up to $10,000 in IRS penalties per unreported transaction – unless they adapt immediately to the finalized 1099-DA rules. The IRS’s June 2025 finalization of Form 1099-DA dramatically expands reporting obligations for digital asset brokers, including certain DeFi platforms, with first filings due in January 2026.

For EU-based MiCA protocols handling US users or assets, this development introduces cross-border challenges, from gross proceeds reporting to cost basis tracking. Non-compliance risks extend to heavy fines, reputational damage, and audit exposure under overlapping MiCA transparency requirements.

This guide breaks down:

  • The 1099-DA essentials and DeFi broker designation.
  • How MiCA protocols are directly affected.
  • Practical steps to navigate dual US-EU obligations while leveraging compliance as a growth driver.

Background: What is Form 1099-DA and Why DeFi Now?

Demystifying 1099-DA

Form 1099-DA is the IRS’s new information return for digital asset brokers, designed to report sales or exchanges of crypto assets such as Bitcoin, Ethereum, or NFTs. Functionally, it mirrors the traditional 1099-B for stock brokers but adapts to blockchain complexities.

Key Dates & Requirements:

  • Proposed: 2023
  • Finalized: June 2025 (IRS Notice 2025-3)
  • Effective for transactions: 2025 (first filings January 2026)
  • Mandatory cost basis reporting: 2026 onward

Core Reporting Requirements:

  • Taxpayer Identification Number (TIN)
  • Asset type
  • Gross proceeds (from 2025 transactions)
  • Cost basis (from 2026 transactions onward)

DeFi’s New Broker Status

DeFi (Decentralized Finance) protocols, such as Uniswap or Aave, allow peer-to-peer trading, lending, or yield farming without central intermediaries. Under the finalized IRS rules, certain DeFi platforms are considered “brokers” if they affect transactions, including via smart contracts.

DeFi Triggers for 1099-DA Reporting:

  1. Automated liquidity pools enabling asset swaps.
  2. Oracle-integrated trades that settle transactions programmatically.
  3. Yield-bearing tokens distributed to users as investment returns.

Note: While transitional relief postpones DeFi filings until January 2028, proactive preparation is crucial to avoid penalties.

MiCA Protocols Under the Microscope: EU’s Regulatory Backbone

Quick Primer on MiCA

The Markets in Crypto-Assets (MiCA) Regulation is the EU’s unified framework for crypto issuance, trading, and services, effective from June 30, 2024 (initially for stablecoins). Full DeFi oversight is expected by December 30, 2024, with ongoing compliance through 2026.

MiCA Coverage Includes:

  • Crypto-asset service providers (CASPs), including DeFi exchanges and custodians
  • Mandatory whitepapers, AML/KYC checks, and consumer protection measures

Core Pillars:

  • Asset classification: ARTs, EMTs, other crypto-assets
  • Licensing via national authorities
  • Cross-border passporting for EU-wide operations

Why MiCA Protocols Are Vulnerable

Overlap with US jurisdiction: ~70% of MiCA protocols serve US users, exposing them to IRS 1099-DA obligations.

The 2026 Shake-Up: Key Changes and Direct Impacts

What’s New in the Final 1099-DA Rules?

Top 4 Changes:

  1. Cost Basis Inclusion – Tracks short- and long-term gains for all relevant transactions.
  2. DeFi Safe Harbors – Certain non-custodial setups exempt from immediate filings.
  3. Thresholds – Only trades above $600 require reporting.
  4. Penalties – Up to $310 per form (inflation-adjusted for 2026).

Reminder: Basis reporting applies to sales after January 1, 2026, with filings due in 2027.

Ripple Effects on MiCA Protocols

  • Reporting Overload: Dual US-EU filings could increase compliance costs by 25% (EY 2025).
  • Cross-Border Risks: Data localization under MiCA conflicts with US IRS TIN sharing.
  • Protocol-Specific Hits: Stablecoin issuers must track redemptions; DEXs must audit smart contracts.
  • Opportunities: Early compliance adoption can increase trust and TVL by 15% with “IRS/MiCA Certified” badges.

 A Berlin-based MiCA protocol avoided $500K fines through proactive 2026 audits.

Compliance Roadmap: 5 Steps for MiCA Protocols in 2026

  1. Assess Broker Status (Q1 2026): Audit smart contracts and consult legal teams.
  2. Upgrade Tech Stack: Implement KYC/AML solutions like Chainalysis for automated 1099-DA reporting.
  3. Train & Document: Update whitepapers with IRS disclosures; educate teams on FIFO/LIFO basis calculations.
  4. File & Monitor: Prepare January 2027 filings; set up alerts for IRS updates.
  5. Stress-Test Globally: Simulate US-EU data flows for MiCA Article 59 compliance.

Pro Tip: Allocate 10–15% of operational budget to 2026 tech upgrades to reduce audit risks.

Frequently Asked Questions

1. What triggers 1099-DA reporting for a MiCA DeFi protocol?

Any trade by a US user exceeding $600 triggers Form 1099-DA reporting.

2. Does MiCA exempt EU crypto firms from US IRS rules?

No. IRS rules apply extraterritorially for US users, even if a firm is EU-licensed.

3. When must the cost basis be reported under 1099-DA?

Cost basis reporting applies to transactions executed after January 1, 2026, filed in 2027.

4. Which DeFi activities are considered brokered transactions?

Automated liquidity pools, oracle-integrated trades, and yield-bearing token distributions.

5. Are non-custodial DeFi protocols fully exempt from 1099-DA?

Some safe harbors apply, but careful analysis is required to confirm exemption.

6. What penalties apply for 1099-DA non-compliance?

Up to $310 per unfiled form (adjusted for 2026 inflation).

7. How does dual US-EU reporting affect MiCA protocols?

Protocols must comply with both IRS 1099-DA and MiCA reporting, potentially doubling compliance workload.

8. Can early compliance improve protocol trust?

Yes. Adopting “IRS/MiCA Certified” status can increase Total Value Locked (TVL) by up to 15%.

9. When do DeFi protocols need to start preparing for 1099-DA filings?

Preparation should begin in 2025, even though transitional relief extends actual filing for some DeFi activities to 2028.

10. Where can EU firms get expert guidance for cross-border compliance?

Specialists like CRYPTOVERSE Legal provide audits, cost basis automation, and IRS/MiCA alignment workshops.
