Contractors will have to pay over all deductions made from subcontractors in any given tax month by the 19th following the end of the tax month to which the deductions relate. If payment is being made electronically, the date will be the 22nd, or the next earlier banking day when the 22nd is a weekend or holiday. If the contractor is a company which itself has deductions made from its payments as a subcontractor, then the deductions made may be set against the company’s liabilities for PAYE, NI and any CIS deductions it is due to pay over.
