We are a Northern Ireland based ltd company with a NI reg number. When we tried to enter our number to get help to file our Annual Accounts for which we are prepared to pay for the system did not recognise our company number either with or without the NI prefix. Pse advise
It should be OK now. I got around this by entering as
NI0*****. I.e. with a prefixed zero. We’ll look into this as it’s not an obvious solution.
