The Chamber’s small business sub-committee has met officers of the Income Tax Department to express their concerns face to face.
Group chairman David Warr said the meeting had been fruitful, for the first time enabling members of the small business community to question the new system.
Mr Warr said his greatest concern was the impact on people who, until now, had come to work in the Island and not paid any tax.
He said the possibility of earning a tax-free sum had been a good incentive.
But under Itis people earning above the annual threshold (£11,000) will be expected to pay tax, even if their work is only seasonal.
