Almost 90% of employers have filed their end-of-year tax returns online - an increase of around 10% compared to last year.
According to new HMRC figures, around 1.4m (87%) returns out of a total of 1.6m were received by the Revenue via its website.
There was also a 23% increase in the number of P14 returns successfully filed, compared to the same time last year. Almost 60m were received, and 70% have already been posted successfully to the National Insurance Recording System.
HMRC director of PAYE, SA and NICs Mike Shipp expressed his delight at the increase in the higher take-up of digital filing.
'We were determined to make the [online] experience as customer friendly as possible', he said, 'and these figures suggest we've gone a long way to achieving this.
'We will continue to encourage smaller employers to file online by listening to their requirements, and meeting those requirements whenever we can - and I hope those small employers who file using the traditional media are encouraged to make the switch to online services.'
