One million people missed HMRC tax return deadline

"Thank you to the millions of people and agents who filed their self assessment tax return and paid any tax owed by 31 January. Anyone who missed the deadline should file their return as soon as possible, as penalties and late payment interest may be charged," said Myrtle Lloyd, HMRC's chief customer officer.

Some who were not required to file this time include those earning more than £150,000, whose high income was the only reason they needed to file previously, or those who had switched to paying the high income child benefit charge through PAYE.
