Quick Answer
Foreign trusts and gifts trigger four reporting scenarios: (1) Form 3520 for receipt of foreign gifts or inheritance over $100K (individual) or $18,567 (2024, foreign corporation/partnership); (2) Form 3520 for transactions with foreign trusts; (3) Form 3520-A for foreign trust reporting by the trust (grantor-filed); and (4) potential throwback tax on accumulated distributions. The short version is that Form 3520 and 3520-A non-compliance triggers 35% penalties that can exceed the transaction value. In our experience, many foreign gifts and trust distributions go unreported because taxpayers don’t realize informational reporting is required even when no income tax is due.1

Four reporting scenarios for foreign trusts and gifts.
The Four Foreign Trust / Gift Scenarios
| Scenario | Threshold2 |
|---|---|
| Foreign Gift | $100K individual / $18,567 entity (2024) |
| Trust Transactions | Any reportable transaction |
| Trust Annual Report | Annual 3520-A |
| Throwback Tax | Accumulated distributions |
Quick Reference
Jump to: gift, transactions, annual, or throwback.
1. Foreign Gift / Inheritance Reporting
Form 3520 Part IV when aggregate gifts exceed threshold.
If this is you: Received gift or inheritance from foreign person. Over $100K from individual, or $18,567 (2024) from foreign corporation / partnership. Form 3520 Part IV required. No income tax on gift typically but informational reporting mandatory.
Foreign Gift Strategy
- Identify foreign person donor.
- Aggregate gifts across year.
- Determine threshold met.
- Gather documentation.
- File Form 3520 by extended 1040 due date.
2. Foreign Trust Transactions
Form 3520 for contributions, distributions, and other trust transactions.
If this is you: Contributed to foreign trust, received distribution, or otherwise transacted. Form 3520 required. Separate from Form 3520-A annual report.
3. Annual Trust Report
Form 3520-A by foreign trust (or grantor if trust doesn’t file).
If this is you: Owner of foreign trust (grantor trust rules). Form 3520-A required annually. If foreign trust doesn’t file, grantor files. Due March 15 (extended September 15).
4. Throwback Tax on Accumulated Distributions
Undistributed net income distributions subject to throwback tax.
If this is you: Receiving distribution from foreign non-grantor trust including accumulated income from prior years. Throwback tax plus interest charge. Can significantly increase effective tax rate.

Frequently Asked Questions
What is Form 3520?
Annual return reporting transactions with foreign trusts and receipt of certain foreign gifts. Informational return — no tax generally due on receipt — but filing is mandatory.
What gifts must be reported?
Aggregate gifts from foreign individuals > $100K annually, or from foreign corporations / partnerships > $18,567 (2024). Inheritances from foreign estates included.
Is Form 3520 income tax?
Generally no. Most gifts not taxable income to recipient. But reporting obligation separate. Non-reporting triggers 35% informational return penalty.
What is Form 3520-A?
Annual information return of a foreign trust with a U.S. owner. Filed by trust or by U.S. grantor if trust doesn’t comply. Due March 15 (extended September 15).
What are 3520 penalties?
35% of amount not reported (gifts, contributions, distributions). Minimum $10K. Can stack across years. Reasonable cause defense available.
What is throwback tax?
Tax on accumulated distributions from foreign non-grantor trusts. Deemed distribution in prior year. Plus interest charge. Significantly increases effective rate.
Do I need to file for small gifts?
Aggregate must exceed threshold. Multiple small gifts from same person aggregated. Related donors may be aggregated.
Is grantor trust reporting simpler?
Grantor trust taxed to U.S. owner. 3520-A required annually. Distributions not taxable to grantor again. Still reporting-intensive.
What is reasonable cause for 3520?
Good faith + reasonable reliance. Lack of knowledge supported by facts. Reliance on competent tax professional. Facts-specific determination.
What if I just found out?
Pro-active late filing with reasonable cause statement. Better than awaiting IRS contact. Attorney-drafted statement recommended.
Can I use streamlined for 3520?
Streamlined program covers 3520 / 3520-A. Non-willful determination required. Coordination with FBAR streamlined typical.
Does inheritance count as gift?
Yes under §6039F. Foreign estate inheritance > $100K reported on 3520 Part IV.
What about foreign life insurance?
Complex. PFIC and 3520 considerations. Some policies reportable; others not. Facts-specific analysis essential.
