It says rising operational costs and investing in public services were factored into the decision
Port St Mary Commissioners will be increasing its rate for the next financial year by 5.9 percent after 'careful consideration'.
The new rate will be set at 419 pence in the pound which will mean an increase of £27 annually on an average three-bedroom household in the village.
Reasons for the hike include the rising operational costs, investing in its public services like waste management and carrying out infrastructure maintenance and improvement.
It will also be undertaking several projects during the year and has committed to working 'closely' with the Treasury to recoup rates debts of more than £20,000.
The local authority says anyone with financial concerns should contact the office on 832101.
