As we open our new diaries and consider the annual entries of birthdays, anniversaries and perhaps planned holidays in the summer HM Revenue & Customs HMRC would also like us to make a note of what it considers to be important dates in the year that if missed could lead to financial consequences including penalties.

So whilst you have your diary to hand you might want to consider some of the following events affecting individuals and businesses in the first half of 2010 and make the appropriate reminder notes. Remember, the Advice Service is on hand to help with any queries, just call 01455 852555 and one of our advisors will be happy to help.
