Form TD F 90-22.1, Report of Foreign Bank and Financial Accounts (also known as FBAR) must be received (not mailed or postmarked) by June 30 each year. If you have not yet completed the form, see my post on March 1, 2010 for how to complete this form and where to send it (also by courier).
In order to confirm that the report was received on time, you can use a courier (EUR 40-60 or more) or send by registered mail (in NL, “aangetekend met toeslag handtekening retour” which currently costs EUR 8.15), both of which can be tracked and require a signature at the other end. I would recommend sending registered, but keep in mind that it can take 2-3 weeks (or more) for aangetend post to be “received” in the US, so send as early as possible.
If you send your FBAR by regular mail (or any other method for that matter), you can get verification of filing by sending a check for $5.00 (for up to 10 accounts), made payable to Internal Revenue Service, to:
IRS Detroit Computing Center
Compliance Review Team
P.O. Box 32063
Detroit, MI 48232-0063
You should include your name, address and Social Security Number (or ITIN) with the request.
This sounds great, but unless you are really early, you won’t find out if they have not received your form until after June 30, since it takes a few weeks to process and another few weeks to get back to you in Europe, potentially exposing you to severe penalties.
To summarize: If you still have enough time, I’d invest the EUR 8.15 for sending “aangetekend” and send at least three, preferably four or more, weeks before the June 30 deadline.
