HMRC is encouraging taxpayers to tweet their tax inquiries because its telephone services cannot cope with calls. According to the press the move has been ridiculed by some MPs and their are significant issues in respect of taxpayer confidentiality which have not been addressed.
If taxpayers have a twitter account and can fit their query into 140 characters they can try tweeting the query to HMRC at @HMRCcustomers. HMRC says don't include anything personal.
