OECD Crypto-Asset Reporting Framework (CARF)

This guide explains the Crypto-Asset Reporting Framework (CARF) — a global initiative by the Organisation for Economic Co-operation and Development (OECD) to standardise tax reporting for crypto assets across jurisdictions. It also shows how wallet hygiene supports compliant and privacy-conscious reporting worldwide.

1) What is CARF?

The Crypto-Asset Reporting Framework (CARF) is an OECD-led standard designed to ensure that tax authorities receive consistent information about cross-border crypto transactions. It complements the existing Common Reporting Standard (CRS) for traditional financial assets.

CARF was endorsed by the G20 in 2023 and is expected to come into force across participating countries beginning 2026.

2) Key components of CARF

Reporting obligations

Crypto exchanges and service providers must identify users, verify tax residency, and report relevant transactions to local authorities.

Cross-jurisdictional sharing

Tax authorities will exchange information globally, similar to CRS, covering disposals, conversions, and transfers.

Scope of assets

Includes cryptocurrencies, stablecoins, tokenised assets, and some NFTs — any digital asset used for investment or payment.

3) Impact on crypto users

Transparency expansion: More countries will automatically exchange crypto account data.
Record accuracy: Users will need detailed records for cost basis, transfers, and sources of funds.
Privacy implications: Non-custodial wallets remain self-managed, but transactions through regulated platforms may be reported automatically.

4) How wallet hygiene supports compliance under CARF

Separation of activity

Use separate wallets for personal, operational, and cross-chain activity to maintain clarity in transaction records.

Traceable yet private

SolanaBlender helps keep internal fund flows auditable while preventing unnecessary public linkage.

Cross-border organisation

Wallet hygiene supports jurisdiction-based classification for tax residency and reporting.
