There is also a growing campaign in Jersey for similar measures.

Jersey Reform Party MP Sam Mezec described the proposed 22% income tax rise in Guernsey as a “bold” move.

He said his party had long supported income tax reform as a way to shore up funding for public services.

He said: “We are in favor of increasing income tax for the highest earners in Jersey.

“The current system is decades old and is not doing what we need for public revenue.”

He added that his party will look to Guernsey to learn the lessons of the increase, if it gets the go-ahead.

The states of Guernsey will meet on November 5 to debate the proposals, which have already met with some opposition.
