Hi Saltergroup20 There isn't a function within QuickBooks that calculates corporation tax and then submits the relevant reports t HMRC. You can however account for corporation tax amount: you will have to manually calculate the amount of corporation tax from your net profit, create a liability account from within the chart of accounts, create a journal moving the amount of corporation tax from the retained earnings to the liability account and then when you pay HMRC you create an expense and in the category column enter the liability account.
In relation to the submission of the relevant reports to HMRC there maybe a 3rd party app available, use the apps section within your account or apps.intuit.com There may also be a Community user that can recommend something.
