HM Revenue & Customs (HMRC) have revealed that a record number of self-assessments, over 6.4 million, were submitted online by the 31 January deadline.
The figure is a 12% increase on 2009's total, and represents nearly two-thirds of all self-assessment returns issued by HMRC every year.
HMRC also confirmed the busiest day was 29 January, where over 384,000 self-assessment returns were submitted online; nearly 39,000 returned were received by the body between the ‘rush hour' of 4pm and 5pm.
"More people than ever before are now filing their tax returns online,' said financial secretary to the Treasury, Stephen Timms MP. 'It's easier, quicker and HMRC processes your return faster, so any money you're owed is repaid more quickly. If you haven't yet made the switch from paper to online, do so, and join the millions who are benefiting already."
