I'm translating a sheet that is titled 'Company details'
It lists some facts about the company that is incorporated in UK. Among other things there are the following:
Accounting Reference Date: 31/12
Last Accounts Made Up To: 31/12/2006 (FULL)
Next Accounts Due: 31/10/2008
Last Return Made Up To: 15/06/2007
Next Return Due: 13/07/2008
What does 'Return' mean here?
