The deadline for registering for Self Assessment is 5 October after the end of the tax year; anyone who needs to register for 2018/19 has less than a week left and this includes those who need to report and pay the loan charge.

There is an obligation to notify HMRC of chargeability to income tax and capital gains tax within 6 months of the end of the tax year.

You have an obligation to Notify HMRC of chargeability to tax if you have, during the tax year:

  • Made a capital gain not covered by exemptions or reliefs and the proceeds exceed £48,000.
  • Employment income that is not taxed under PAYE. 
  • Dividend income and further tax to pay on that income.
  • Any other untaxed income or are liable to tax at higher rates, including where you are subject to the High Income Child Benefit Charge

If you fail to notify HMRC of your chargeability to tax and have unpaid tax on 1 February 2020, penalties will be due unless you have Reasonable excuse for the failure. You can register with HMRC for self-assessment here.

Self Assessment and the Loan charge

For 2018/19 only, individuals who had outstanding loans from Disguised remuneration schemes on 5 April 2019:

  • who are not in the process of settling with HMRC and 
  • who are not already registered for self-assessment

must register by 5 October and

  • Submit a self-assessment return by 31 January 2020
  • Declare their loans subject to the charge and
  • Pay the tax due unless it has already been deducted in full by their employer under PAYE.

The requirement to include these loans on the self-assessment return is in addition to the obligation to report details of loans to HMRC by 1 October 2019.
