just a follow up ; our Company fiscal year ends 9/30

this is for calendar year plan year ending 12/31/07

The excise tax is due on the last day of the 15th month following the close of the plan year - so 3/31/09 in your situation. Your fiscal year end has no impact on this deadline - and the fact that you extended your 5500 to 10/15 has no impact on this deadline either.
