Form 12 and Form 11 due?

I recall receiving these forms a good deal earlier in the post last year, I have still received nothing from revenue and there is no indication from friends that they have received same, why might this inconsistancy occur and am I to assume that the process is random!

Firstly you would be filing either F12 or F11 not both. F12's have issued to a lot of taxpayers some months back. However not everyone receives one every year. F11's , where being done manually and not on ROS have also issued. If you have an obligation to file F11 then the due date for manual 2008 returns is 31/10/09 or 17/11/09 if filed and paid on ROS. If you should have received one and have not then I suggest contacting your tax office.
