HMRC has launched a targeted compliance exercise focusing on Construction Industry Scheme (CIS) contractors whose monthly returns may contain incorrect subcontractor deduction rates.
Affected contractors may be contacted by HMRC and asked to review their returns, correct any errors and provide further information where needed.
Accountants dealing with CIS clients may wish to check that deduction rates used on recent returns match the rates obtained through the CIS verification process.
