March 7, 2014 For Limited Companies the accounting year end of your Company is usually different to the personal tax year. The personal tax year is 6th April to 5th April (for the purposes of a set of Sole Trader or Partnerships accounts this is often rounded to 1 April to 31 March for simplicity – different dates can be used but lets keep it simple for now) Companies House gives your company an ‘accounting reference date’ – this is when they expect your company’s year end to be and by default it will be 12 months on from the end of the month in which you registered your company. So if you registered your company on 10th May 2013, the first year end date will be 31st May 2014 and every 31st May thereafter. See information here about corporation tax. You can actually change the accounting reference date but there are certain stipulations so please discuss that with us.
