Long-Term International Tax Efficiency
U.S. Tax Planning For Foreign Trusts
When a foreign trust has U.S. connections—whether through a grantor or beneficiary—it triggers complex U.S. tax rules and reporting requirements.

We provide clear, proactive counsel to both offshore trustees and U.S. beneficiaries, helping mitigate risk, reduce throwback tax exposure, and maintain compliance with IRS mandates.
- Determine U.S. grantor vs. nongrantor trust status
- Comply with FATCA, Form 8938, Form 3520/3520-A, and FBAR
- Minimize throwback tax through distribution planning
- Structure cross-border trusts for long-term efficiency
- Coordinate with foreign trustees and legal advisors
