You will be treated as a non-resident individual providing that:
As a non-resident your earnings will be subject to tax at the rate of 20%.
Non-resident workers who are married/civil partners are not entitled to opt for joint taxation with their spouse/partner. If a non-resident couple are both employed in the Isle of Man, then both parties will be liable to pay tax on their earnings.
Non-resident individuals will also be required to complete a non-resident return when leaving the island.
No, you don't but your employer does. Your employer should keep a record of all wages paid and all benefits received during your time in employment. These details will then be declared when they submit their employer's return at the end of the tax year.
