January 2021

This deadline is relevant to individuals who need to complete a self assessment tax return and make direct payments to HMRC in respect of their income tax, Classes 2 and 4 NI, capital gains tax and High Income Child Benefit Charge liabilities. 

There is a penalty of £100 if your return is not submitted on time, even if there is no tax due or your return shows that you are due a tax refund.

The balance of any outstanding income tax, Classes 2 and 4 NI, capital gains tax and High Income Child Benefit Charge for the year ended 5th April 2020 is due for payment by 31st January 2021.  Where the payment is made late interest will be charged.

The first payment on account for 2020/21 in respect of income tax and any Class 4 NI or High Income Child Benefit Charge is also due for payment by 31st January 2021.

If we have already dealt with your self assessment return on your behalf you need take no action.

March 2021

The final deadline of 5th April 2021 is relevant to individuals who have not considered year end tax planning issues.  These issues include:

  • utilising your annual capital gains tax exemption
  • utilising your annual inheritance tax exemption for gifts
  • utilising your annual Individual Savings Account investment limit (ISA)
  • making additional pension contributions for 2020/21.

Please do get in touch if you would like any further advice on these or any other issues.
