“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.
Millions of people have tax automatically deducted from their wages through PAYE (pay-as-you-earn), but those with more than one source of income may need to file each year through self-assessment.
They included those earning more than £1,000 in the 2024-25 financial year from self-employment or by letting out a property or land.
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.
