Fascinating facts about Self Assessment

ADVERTISEMENT

HMRC has shared some little-known facts about Self Assessment ahead of the 31 January 2021 deadline.

Did you know almost 100,000 people filed their tax returns on 6 April 2020, which is the first day of the tax year?

With the 31 January 2021 deadline fast approaching, HM Revenue and Customs (HMRC) shares some little-known facts about Self Assessment tax returns.

The April ‘early birds’ are not the only ones to make HMRC’s list of Self Assessment facts; it is also 20 years since the tax authority introduced online tax returns. In 2001, 38,000 online tax returns were filed and this year, HMRC estimates around 11 million online tax returns – quite the increase and in line with the digitisation of the tax system.

HMRC’s 7 Self Assessment facts are:

  • 96,519 people filed their tax return on 6 April 2020 (first day of the tax year)
  • it’s the 20th anniversary of Self Assessment internet filing, the service began on 3 July 2000 – with 38,000 individuals successfully sending their digital tax return by 31 January 2001
  • in January 2011, 3.4 million taxpayers completed a Self Assessment tax return online – this has increased to an estimated 5 million in January 2021
  • this year’s deadline (31 January 2021) is on a Sunday. The last time the deadline was on a Sunday was in 2016
  • last year, the busiest filing day was 31 January with 702,171 returns completed
  • the peak hour for filing last year was between 16:00 to 16:59 on 31 January when 56,969 customers filed
  • HMRC has increased the self-serve Time to Pay threshold to £30,000 to help Self Assessment customers spread the cost of their tax bill

Karl Khan, HMRC’s Interim Director General for Customer Services, said:

“It’s 20 years since Self Assessment online was introduced and it’s how the vast majority of customers complete their tax return these days. Fewer and fewer people are doing it on paper each year.

There’s still time for customers to complete their tax return before the deadline, and help and support is available on GOV.UK.

HMRC expects more than 12.1 million people to complete a Self Assessment tax return. Figures released earlier this month revealed that 55% of customers have already filed their returns, with more than 6.2 million choosing to submit online (93% of all returns filed).

Once customers have completed their tax return, and know how much tax is owed, they can set up their own payment plan to help spread the cost of their tax liabilities.

They can use the self-serve Time to Pay facility to set up monthly direct debits online.

This year, in light of the additional pressures caused by COVID-19, HMRC has increased the self-serve Time to Pay threshold to £30,000 to help Self Assessment customers spread the cost of their tax bill. Interest will be applied to any outstanding balance from 1 February 2021.

To see if they’re eligible, customers can visit GOV.UK to find out more about paying through instalments.
