Construction Industry Scheme Support for UK Accountants

CIS work looks simple until contractor data arrives late, subcontractor verification is unclear, material splits are missing, deduction rates are inconsistent, or a nil month has not been recorded properly.

LekhaWekha provides outsourced CIS returns for UK accounting firms through a white-label production desk. We prepare the schedules, checks, deduction notes, and reviewer handoff pack while your practice keeps client approval and final HMRC filing control.

Whether your construction clients pay a few subcontractors or manage complex monthly contractor records, our offshore CIS desk helps your team stay organised and deadline-ready.

What Your CIS Pack Includes

  • Subcontractor verification checks and verification reference notes
  • CIS deduction rate review for gross, standard, and higher-rate cases
  • Labour, materials, VAT, and non-CIS item separation support
  • Monthly CIS300 return preparation support and exception notes
  • Nil return and inactivity tracking prompts
  • Payment and deduction statement support for subcontractors
  • White label construction industry scheme returns that UK firms can deliver under their brand

Outsourced CIS Returns UK Accounting Firms

Under the Construction Industry Scheme, contractors need to manage subcontractor verification, deduction rates, monthly contractor returns, payment records, and deduction statements. HMRC guidance explains that monthly returns must be filed for payments to subcontractors and that contractors need to keep full CIS records.

LekhaWekha supports outsourced CIS returns for UK accounting firms when construction clients create repeat monthly admin but internal capacity is limited. We prepare the schedules, checks, query logs, and filing-ready return pack for your review.

What Are CIS Returns?

CIS returns are monthly contractor reports showing payments made to subcontractors under the Construction Industry Scheme, including relevant deductions. The return should align with contractor records, subcontractor verification details, payment data, and deduction statements.

Why UK Accountants Outsource CIS Monthly Returns

CIS processing is repetitive, detail-heavy, and deadline-led. Outsourcing the preparation layer gives your reviewers more time to focus on client advice, filing approval, and exception handling.

  • Prepare monthly CIS return schedules from contractor payment records
  • Check subcontractor verification details and deduction rates
  • Separate labour, materials, VAT, and non-CIS amounts
  • Prepare deduction statement support and client query logs
  • Deliver white label construction industry scheme returns that UK practices can scale under their own brand
