The Construction Industry Scheme (CIS) number is a unique identifier assigned by HMRC to contractors or subcontractors operating within the UK construction sector for tax deduction purposes.
Tax obligation explained
This query relates to locating a Construction Industry Scheme (CIS) number, which is essential for businesses or individuals involved in construction work in the UK. The CIS number is used by HMRC to track payments and deductions under the scheme, ensuring compliance with tax obligations for construction-related transactions. Contractors must verify subcontractors' CIS status before making payments, while subcontractors use their CIS number to confirm their registration and tax deduction rate.
Key legal requirements
- Check HMRC’s online service or business tax account to retrieve your CIS number
- Contact HMRC’s CIS helpline if the number is not available online
- Ensure the CIS number is registered under the correct business or individual name
Why this matters
Failing to provide or verify a CIS number can result in incorrect tax deductions or penalties for non-compliance. Contractors may face fines for not verifying subcontractors, while subcontractors could be subject to higher deduction rates if their status is not confirmed.
