The Charity Commission for Northern Ireland has published new guidance on when charitable organisations will be called forward to register – ‘The who, what, where, why, when and how of charity registration in Northern Ireland’ in pdf, 875KB, or start from CCNI news item.
English/Welsh charities operating in NI will be called last, which is not currently expected before 2017 at the earliest, but can (if they want) complete an ‘expression of intent form’ https://www.surveymonkey.com/s/V7LLKJP and state current registration status in question 9. Independent NI branches of English charities may need to register earlier. (With thanks to Bates Wells Braithwaite weekly review.)
UPDATE: Since the above was written, the Charity Commission for Northern Ireland commenced compulsory registration of charities on 16th December 2013.
