@grainger20011 assuming that each of you ( yourself and your spouse ) is a US persons ( citizen / GreenCard / Resident for tax purposes ), and each being a beneficiary of gift/ inheritance from foreign person/ trust/estate meeting the threshold for recognition requirements , should file an individual form 3520. This is true even though you are filing jointly just like individual W-2s, 1099s etc..
Does this make sense ? Is there more I can do for you ?
