Tax return urgent.plz advice seniors

I would be applying for Tier 1 general extension in July’2012 with earnings shown from my permanent job and limited company. I started the limited company in Nov’2011 and couple of weeks ago I received a notice letter from HMRC stating me to file the Tax before Oct’2012 or Jan’2013(online). My accountant has advised me that I should be filing my tax return in Oct’2012 or later via online.
My query is should I submit my application for extension without the tax return or with tax return? if yes how do I prepare my tax return. Please advice.
Thanks in advance.

Somebody please advice.

bash, be advised that members of this board are allowed to go to sleep! Your second post, just 8.5 hours after the first, the hours of night, is not appreciated.

The Notice to File letter your have received relates to you, and not your company. If all the facts are known there is nothing to stop your Self Assessment tax return being filed now.

I find that confusing. The return can be filed online now. It is not necessary to wait until October to file online.

thanx a ton,sorry for disturbance.
