Form 3520: foreign trusts and large gifts
Reporting for US persons who deal with a foreign trust, or who receive a substantial gift or inheritance from abroad.

Reportable and taxable are different questions.
Form 3520 covers two quite different things: transactions with foreign trusts, and large gifts or bequests received from non-US persons.
The second catches people who owe no tax at all. An inheritance from a foreign relative is generally not US-taxable to the recipient, but above the threshold it is still reportable.

In detail
01
Foreign trusts
Creating, funding, or receiving distributions from a non-US trust is reportable. An ordinary UK family trust is a foreign trust for these purposes.
02
Grantor and non-grantor
Whether the trust is treated as owned by its settlor changes who reports what, and whether Form 3520-A is required in addition.
03
Gifts and inheritances
Above the threshold, report the amount and the relationship. There is generally no tax on the recipient — the obligation is disclosure.
04
Throwback rules
Accumulated income distributed later from a foreign trust can be taxed at punitive rates with an interest charge, so distribution timing is worth planning.

Frequently asked
My parents gave me money from the UK. Do I report it?
If the total from non-US individuals exceeds the threshold in a year, yes. It is reporting rather than tax, but the penalties for missing it are real.
Is a UK bare trust reportable?
Possibly, depending on how it is classified for US purposes. The UK label does not determine the US analysis.
What if I have missed years?
Reasonable-cause relief exists and correcting voluntarily is materially better than waiting for contact. This is worth advice before filing anything.
