CIS Monthly Returns
Monthly CIS returns, subcontractor verification, WIP reporting, and retainage tracking.
CIS Monthly Returns— what we do
If you are a contractor in the construction industry, we handle your CIS obligations end to end. We verify subcontractors, calculate and apply the correct deduction rates, submit monthly returns to HMRC, and provide payment and deduction statements. We also manage WIP (work-in-progress) reporting, retainage schedules, and application-for-payment workflows — the construction-specific accounting that generic accountants miss.
