My husband and i have just started a new business, we are a C x A registered company. We pay our Itibis every month (however we have been infirmed that as we are artists/performers we do not have to charge or pay itibis, any more information on that is also welcomed). We are unsure what the N.C.F numbers we have been supplied for each invoice are for, i presume another tax or is a number that corresponds to the itibis???????? we have had very little advice and are also unsure of what bookeeping is required here. This is my first business and is doing extremley well, i do not want to mess it all up should we be paying something i am unaware of and the tax man comes knocking. Any start up information would be extremley helpful. thank you
