COLLECTING UNPAID TAX FOR 2017/18 THROUGH YOUR PAYE CODING
Under certain circumstances it is possible to arrange the collection of unpaid tax through your PAYE coding rather than making a balancing payment on 31 January. This will depend upon the amount outstanding and the amount of income taxable under PAYE.
There is a further condition that the return is submitted to HMRC online before 30 December 2018 in order that the 2017/18 tax be collected by amending the 2019/20 PAYE coding. So please get your tax return information to us as soon as possible if you would like to take advantage of this facility.
