Frequently asked questions
What is a CIS Tax Return and who needs to file it?
A CIS Tax Return is a monthly report required under the Construction Industry Scheme. Contractors must submit returns to HMRC detailing payments made to subcontractors and any deductions applied. Subcontractors may also need to file annual returns to reconcile their tax position.
How can an ACCA qualified accountant help with CIS Tax Returns?
An ACCA qualified accountant brings expert knowledge of the Construction Industry Scheme and HMRC compliance. They can prepare and submit your CIS returns accurately, ensure correct deduction rates are applied, and help you claim back overpaid tax. Their training guarantees up-to-date advice on regulatory changes.
What records do I need to keep for CIS Tax Returns?
You must keep records of all payments to subcontractors, including their name, Unique Taxpayer Reference, and the amount deducted. You should also retain verification documents and any correspondence with HMRC. A qualified accountant can advise on proper record-keeping to avoid penalties.
Can an ICAEW accountant help with both CIS and Corporation Tax?
Yes, an ICAEW accountant is trained to handle both CIS Tax Returns and Corporation Tax. They can integrate your construction scheme obligations with your company's overall tax planning. This ensures that your year-end accounts and limited company annual accounts reflect all deductions and liabilities correctly.
What happens if I miss the CIS Tax Return deadline?
Missing the deadline results in automatic penalties from HMRC. The first late return incurs a £100 penalty, with further charges for continued delays. Interest may also be applied to any unpaid tax. Engaging a professional ensures your returns are filed on time and accurately.
