The Association of Chartered Certified Accountants (ACCA) yesterday claimed the introduction of the proposed new tax on development could hinder the construction of housing.
The industry body said that a new Planning Gain Supplement - which will act as a levy on landowners selling their land - will put developers off investing in new homes.
Chas Roy-Chowdhury, ACCA head of tax, said: 'The system needs to be as simple as possible. These regulations are very opaque and could cause confusion for the small landowner looking to benefit from a sale.'
The government concluded a consultation on the introduction of the tax earlier this week.
