HMRC is making changes to the PAYE coding notices system.
From 31 May 2017, HMRC will be using data received under RTI and from taxpayers’ personal tax accounts to update tax coding notices as a move towards Making Tax Digital. HMRC believe changing tax codes more frequently during the tax year will help taxpayers pay the correct amount of tax at the right time avoiding unexpected tax liabilities and creating tax repayments sooner.
Employers and pension providers will see a rapid increase in the number of revised tax codes being issued. Taxpayers will receive copies of their revised coding notices in the post and have access to tax codes through their personal tax accounts. However, agents will no longer receive paper copies of tax codes and there is no prompt to notify them of any changes so taxpayers should forward any tax codes received to their accountants straight away.
