Almost 1m people missed last Friday’s tax return deadline and 11.1m hit the deadline and completed their self-assessment tax reforms.
Angela MacDonald, director general for customer services at HM Revenue & Customs (HMRC) said, “Customers who have missed the deadline should contact HMRC.
“The department will treat those with genuine excuses leniently, as it focuses penalties on those who persistently fail to complete their tax returns and deliberate tax evaders.
“The excuse must be genuine and HMRC may ask for evidence.”
Currently those who miss the deadline can face a penalty of £100, and after three months additional penalties of £10 per day can be claimed, to a maximum of £900 by HMRC.
