Some will have longer to pay due to delays processing returns
Manx residents are being reminded that tax payments are due in just over two weeks.
Outstanding amounts for 2019-20 personal tax assessments, and payment on account notices for the current financial year are due by 6 January.
The Treasury says processing tax returns is likely to take longer this year due to the coronavirus pandemic.
As a result, those who receive a bill after 6 December have 30 days to pay from the date of the notice.
