Why this mattersReceive a £100k gift from your UK parent? That's a Form 3520 — and the penalty is 25%.
Form 3520 catches a lot of people by surprise. Most US persons think gift tax is the giver's problem (it usually is) — but if a foreign person gifts you over $100k in a year, you have a separate IRS reporting obligation. Foreign trust interests are stricter still. Penalties for late or missing forms start at 25% of the unreported amount, and the IRS automates them. Most of our clients on this work didn't know the form existed until they were already at risk.
