The IRS has finally opened a hotline to address FBAR concerns. Though much delayed, this should at least give expats an opportunity to get much needed clarification and help.
To reach the FBAR and Title 31 Helpline, dial (866) 270-0733 for toll-free calls within the U.S., or (313) 234-6146 for callers outside the U.S. The latter is not a toll-free phone number.
Although it says that the toll-free number is within the US only, American toll-free numbers usually work in Canada too (and visa versa). It may be worth giving that a try first, assuming it all goes to the same call centre.
