### HMRC Issues £100 Penalties to One Million Taxpayers for Missing Tax Return Deadline The HM Revenue and Customs (HMRC) has confirmed that approximately one million taxpayers in the UK are facing automatic £100 penalties for failing to submit their self-assessment tax returns by the January 31 deadline for the 2024/25 financial year.
