Principal contractors are required to complete Form C45 on making payments to sub-contractors who have not been certified by the Revenue Commissioners to receive payments without deduction of tax. Where such payments are made the principal contractor must deduct tax at 35 per cent of the gross amount of the payment; no reduction is made for expenses or allowances. Copies of the forms are provided to the sub-contractor and to the Revenue Commissioners.
There is a tight system of control supported by an outdoor inspection programme which, inter alia, supervises and monitors the system generally and also follows up specific cases where there is attempted or suspected abuse. In the past week the Revenue Commissioners have become aware of a campaign by construction workers against attempts by contractors to place employees on the C45 system. The Revenue Commissioners have not been approached directly on this issue but note from the media that some contractors have in recent times attempted to change the status of employees to sub-contractors.
