Corporation tax on balance sheet as "asset"

We haven’t switched to QuickFile from anything, we’ve been using it since we set up the company in May 2012.

We run the business in our spare time so we only have around five clients and very few payments to reconcile. Because of this I thought accounting would be relatively simple!

From what I’ve read and what you’ve said, it seems that tagging the bank transaction as Corporation Tax has debited the “Corporation Tax (2320)” account with that amount. Based on Joe’s answer to this question, it seems I need to add a credit to the “Corporation Tax Charge for the Year (8500)” account. How can I do that when journal entries need to balance? Do I need to “untag” the bank transaction first?

Even if/when I’ve managed to do this, I still don’t know whether it’ll disappear from the assets on the balance sheet. Especially as the tagging process seems to debit account 2320 again for the same amount.
