CIS Return Services That Are HMRC Compliant
If you work in the construction industry, submitting an accurate CIS return on time is essential to avoid penalties and remain HMRC compliant. Our expert CIS return services ensure contractors and subcontractors meet all tax obligations while maximising efficiency and minimising errors.
What is a CIS Return and Who Needs to File One
The Construction Industry Scheme (CIS) is a tax scheme where contractors deduct tax from subcontractors’ payments and report these deductions to HMRC via a CIS return each month.
You must submit a CIS return if you:
- Are a contractor paying subcontractors for construction work
- Deduct CIS tax at 20% or 30% from subcontractor payments
- Operate in construction, demolition, repairs, or site preparation
- Employ self-employed workers under the CIS scheme
Failing to submit CIS returns accurately and on time can lead to HMRC penalties and compliance issues. Working with a professional ensures accuracy and compliance while reducing administrative burden.

CIS Returns FAQ’s
What information do I need to complete a CIS return?
To complete a CIS return, you’ll need the subcontractor’s details, the amount paid before and after deductions, and the CIS tax deducted. You also need to ensure each subcontractor is verified with HMRC. Our CIS return service ensures all required information is accurate and submitted correctly each month.
How do I claim a CIS tax rebate as a subcontractor?
To claim a CIS tax rebate, you must submit a Self Assessment tax return that shows how much CIS tax has been deducted. Our team helps subcontractors claim their CIS tax rebate quickly and ensures they recover any overpaid tax from HMRC without delay.
What happens if I don’t file a CIS return on time?
If you miss the CIS return deadline, HMRC may issue automatic penalties starting from £100, increasing the longer it remains unfiled. Failing to submit can also lead to compliance checks or further investigations. Our monthly CIS return filing service helps you stay on time and avoid these penalties.
