Which proposals target overseas crypto holdings?

TLDR

The two live proposals aimed at overseas crypto holdings are the US plan to join the OECDs Crypto?Asset Reporting Framework (CARF) and Brazils move to tax cross?border crypto use and align reporting with CARF.

1. US Broker Digital Transaction Reporting under CARF would require visibility into Americans foreign crypto accounts, similar to FATCA and FBAR rules (White House review).
2. Brazil is considering extending the IOF tax to international crypto payments and adopting CARF?aligned reporting for offshore activity (policy outline and update).

Deep Dive

1. US CARF Adoption

The US proposal would align its crypto tax regime with CARF, enabling automatic cross?border sharing of digital asset account data.

1. The Broker Digital Transaction Reporting rule under review would give the IRS access to Americans foreign crypto account data, echoing FATCAs approach to offshore bank accounts (policy review).
2. Administration guidance has emphasized avoiding new burdens on DeFi transactions while closing offshore reporting gaps via CARFs data?sharing standards (summary).
3. Market coverage notes the White Houses review as a step toward CARF implementation and stronger offshore transparency for US taxpayers (background).

2. Brazil IOF + CARF Alignment

Brazil is tightening rules on cross?border crypto and moving toward CARF?style reporting, with tax and forex treatment changes.

1. Authorities are weighing an IOF (financial transaction tax) extension to international crypto payments, treating some stablecoin operations as foreign exchange to close loopholes (policy outline).
2. Updates highlight Brazils intent to align its reporting rules with CARF, enabling access to citizens foreign crypto account data under the OECD standard (update).
3. The shift pairs stricter oversight with existing capital gains taxation and new reporting thresholds for offshore transactions (policy outline).

Conclusion

Current proposals in the US and Brazil converge on the same outcome: automatic information exchange and tighter tax treatment for foreign?held crypto. If these rules advance, offshore positioning will require robust reporting, and the benefits of routing activity through foreign venues will shrink. Monitoring the White Houses CARF decision and Brazils IOF application to crypto will clarify timelines and practical obligations.
