Parent passed away in April 2018 in the U.K.  Estate has been liquidated, but no funds have been moved to the US taxpayer's custody yet.  US taxpayer wants to know whether to move the entire amount in 2018 (approx. U$S 350K) or split it into amounts <$100K over 3 or 4 years. Does it matter at all from a tax liability standpoint?

Funds are in a non-interest bearing account in the UK; taxpayer's brother is the executor/custodian of the funds.

Thanks very much for the response.

Your client will also need to file a F.8938 in addition to F.3520.  Although duplicate reporting of the SSFA is not required, it will still be necessary to identify on which form you reported the SFFA and the number of forms filed.
