Deadline less than a month away
An increasing number of the Manx public are now submitting their personal tax returns online.
Statistics revealed by the Treasury show 11,000 returns have been sent using government's online service.
That's 35 per cent of all received so far, compared to 30 per cent at the same stage last year.
Gerard Higgins from the Treasury's Income Tax Division says the rise is encouraging and those using the online service will have refunds processed faster.
Returns must be submitted by October 6, with a £100 penalty in place for those missing the deadline.
