10.2m people filed self-assessment by deadline HMRC says more than 10.2m customers filed their 2020/21 tax returns by the 31 January deadline. Of these, over 630,000 customers filed on deadline day. The peak hour for filing ahead of the midnight cut-off was between 4pm and 5pm, with 52,475 people completing their self-assessment in the period. It was also found that 20,947 customers cut it fine, completing their tax return between 11pm and 11:59pm. The remaining 2.3m customers expected to file by January 31 now have until 28 February to submit their late 2020/21 tax return and avoid a late filing penalty. Myrtle Lloyd, HMRC’s director general for customer services, commented: “We’re waiving penalties this year, to give those who missed the deadline an extra month. And customers can set up a monthly payment plan online if they’re worried about paying their tax bill.”
