About CIS Tax Returns
The Construction Industry Scheme (CIS) was created by HMRC to ensure the correct tax is paid within the construction sector. Under this system, contractors deduct tax from subcontractors’ payments and send it to HMRC. When you file your CIS tax return in Portsmouth, it ensures your records are up to date and allows you to claim any overpaid tax back.
We carefully review your CIS deductions, income, and expenses before preparing and submitting your return. Our aim is to make sure you claim every refund you’re entitled to and avoid any filing errors that could cause delays or penalties.

A CIS (Construction Industry Scheme) Return is a monthly report contractors must submit to HMRC, detailing payments made to subcontractors and the tax deductions taken. Cloudco ensures your CIS Returns are completed accurately and on time.
Missing deadlines can result in HMRC penalties. Cloudco tracks your filing dates, submits on time, and prevents costly fines.
No, subcontractors don’t file CIS Returns. Instead, contractors file them. However, subcontractors may need to file a Self Assessment Tax Return to reclaim overpaid CIS deductions. Cloudco can assist with both.
You’ll need details of subcontractor payments, invoices, and deductions. Cloudco manages these records digitally to make the process simple and efficient.
