Simple Assessment 5th October 2017 HMRC have now implemented their ‘Simple Assessment’ project, where they use the information already available to them from employers, pension providers, the DWP and banks to calculate the tax for those with straightforward or ’Simple’ tax affairs, without the need for a tax return to be completed. In theory this sounds like an excellent plan, and many will be asking why HMRC have not used the information to hand in the past! However these calculations will need to be checked carefully as we are already seeing incorrect calculations in issue. In particular as HMRC do not receive details directly of investment income, other than bank interest, if taxpayers hold any shares or other forms of investment the calculations may not be correct. Taxpayers have 60 days in which to contact HMRC if the calculations are incorrect.
