It's that time of year again when, for our amusement, HM Revenue and Customs release their annual list of the 10 worst excuses taxpayers have given in the past year for filing a late tax return. The worst (best!) tax return excuses are ... \tMy pet dog ate my tax return\u2026and all the reminders. \tI was up a mountain in Wales, and couldn\u2019t find a post box or get an internet signal. \tI fell in with the wrong crowd. \tI\u2019ve been travelling the world, trying to escape from a foreign intelligence agency. \tBarack Obama is in charge of my finances. \tI\u2019ve been busy looking after a flock of escaped parrots and some fox cubs. \tA work colleague borrowed my tax return, to photocopy it, and didn\u2019t give it back. \tI live in a camper van in a supermarket car park. \tMy girlfriend\u2019s pregnant. \tI was in Australia. You won't be surprised to hear that none of these tax return excuses led to a successful appeal! You are allowed to claim there is a 'reasonable excuse' for filing late but, if you file your return after 31st January you will need to come up with more convincing tax return excuses than this to avoid being fined!
