Employers and contractors are being reminded the deadline for tax returns is in just over two weeks time.
The government is reminding people they must be sent to the Income Tax Division by Sunday, May 5.
Officials are warning those who fail to submit them before this date could face a £250 fine, and could be charged a further £50 per day for each day they haven't been returned after that.
They can be submitted online at www.gov.im/onlineservices.
