Cancellation in 2009 means that the enterprise has been liquidated, so no one will audit the accounts, but you'd better keep your original tax payment certificate.

I see. It seems that you didn't cancel your business, but made a tax change. If so, it is still possible to be investigated. If I look up the accounts in 2009, I want to look at the accounts in 2008 (at least in 2008). I need to know the previous fixed assets (depreciated in tax basis in 2009), the tax payable in 2008, the tax paid in 2009 and so on.
