yikes - looked at the FBAR form and under penalty it says:
A person who is required to file an FBAR and fails to properly file may
be subject to a civil penalty not to exceed $10,000 per violation. If there
is reasonable cause for the failure and the balance in the account is
properly reported, no penalty will be imposed. A person who willfully
fails to report an account or account identifying information may be
subject to a civil monetary penalty equal to the greater of $100,000 or
50 percent of the balance in the account at the time of the violation.
As I am self employed there is usually some time in each tax year when I have over $10,000 in the bank - and then I trun it all over to HMRC. Can they really fine me $10,000 for each year I didnt file an FBAR? The interest I earn on my bank accounts probably never comes to more than £100/year as the average balance is not that high. Maybe the amnesty in september would be a good way to go, but having read a little about that it also seems that you could get hit with the $10,000 penalty if you cant prove it wasn't willful.
