TR1 Form - Accounts Date Question?

Hi there - I wonder if anyone can help with this? I started doing freelance work (travel) middle of 2008 & am in process of registering as self employed by filling out TR1 - not sure how to answer one question on the form:
"To what date will annual accounts be made up?"

From doing a little bit of research it looks like I can choose any date. I origninally was just going to put 31st Dec each year to tie in with the tax year but is there a disadvantage to this? Or is there another date which would be better to use from tax purposes?
Would be grateful for any extra info on this?!
Many thanks!

I use 1 Dec as it's easiest.

Did you mean 31 December. I think that is easiest.

So there is no tax advantage using a date other than tax year 31st Dec?

There caqn be an advantage of picking a different date to delay the time when you need to file your final tax return. But you are only delaying.
