HMRC’s Dynamic Tax Coding System

2018-19 is the first tax year that HMRC will use their new dynamic coding system to issue tax codes at the beginning of the tax year.

You should check all tax codes sent to you but for 2018/19 some of the things you should look out for are:

  • the ‘S’ prefix missing for Scottish taxpayer
  • personal tax free allowances being left out
  • no pension tax relief for higher or additional rate taxpayers
  • deductions for a source of income e.g. benefits in kind bank interest that you no longer receive
