Tax compliance becomes especially complicated when foreign money is involved. U.S. taxpayers who receive large gifts or inheritances from abroad may face unique obligations, including the requirement to file Tax Form 3520. Failing to meet these obligations can expose taxpayers to serious financial penalties, making it crucial to understand what the form is, why it matters, and how to stay compliant.
What Tax Form 3520 Requires
Form 3520 applies to U.S. persons who receive more than $100,000 in foreign gifts or bequests in a calendar year. This threshold includes both direct and indirect transfers, meaning even if funds pass through an intermediary, they still must be reported.

The consequences of failing to file are steep. The IRS imposes a penalty of 5% of the unreported amount for each month the form is late, up to 25%. Historically, taxpayers could avoid penalties by attaching a reasonable cause letter explaining why the filing was delayed. However, in recent years, the IRS often assessed penalties automatically without reviewing these letters, leaving many well-intentioned taxpayers with costly penalties to fight.
Recent IRS Policy Changes
In October 2024, the IRS announced a significant change. Commissioner Danny Werfel confirmed that the agency would no longer automatically assess penalties for late-filed Forms 3520 and 3520-A. Instead, IRS staff will now review reasonable cause statements before deciding whether to impose a penalty.
This adjustment represents a fairer system, giving taxpayers the chance to present their case upfront rather than appealing after the fact. While processing times may increase, the new policy reduces the risk of unwarranted penalties. The change is especially important for those with compelling reasons for late filing, such as illness, natural disasters, or difficulties accessing records.
Filing Strategies and Compliance Options
Even with this positive shift in policy, taxpayers should not delay compliance. Filing late with a detailed reasonable cause statement remains the primary strategy for avoiding penalties. For some, the IRS Streamlined Filing Procedures may also provide a path to compliance.

The burden of proof remains on the taxpayer to demonstrate why the delay occurred and why it should be excused. Because of this, expert guidance is critical to presenting the strongest possible case.
