Isle of Man personal tax return deadline looming
Island residents who fail to file their personal income tax returns before October's deadline will have to pay a £100 fine, according to the Treasury.
They have until 6 October to hand in their completed forms at the Isle of Man government offices or complete their form online.
Last year, more than 3,000 people were fined for missing the deadline.
If the individual fails to file their return by 6 April 2013, the charge will rise to £200.
Gerard Higgins, of the income tax division, said: "We don't want anyone to be charged, so we would urge people to get their returns in a soon as possible.
"We would encourage as many people as possible to use our online service."
From 17 September to 5 October a team of officers will be available at the income tax division from 11:30 to 14:00 BST to assist people wishing to learn more about the online service.
From 17 September 2012 to 5 October 2012, a dedicated team of officers will be available from 11.30 BST.
