CIS TAX Returns in Ealing
If you’re a contractor or subcontractor operating in the construction sector, managing your duties under the Construction Industry Scheme (CIS) is not optional — it’s essential. At Interface Accountants, we provide fully compliant CIS returns services in Ealing, helping construction businesses and self-employed workers file accurately, avoid penalties, and recover what they’re owed.
Whether you’re running a small crew or working solo as a subcontractor, our team ensures that your deductions, payments, and tax returns under the scheme are handled smoothly and on time.

Understanding CIS Obligations
Under HMRC’s Construction Industry Scheme, contractors must deduct tax at source from subcontractors and report these payments monthly. Subcontractors, on the other hand, must track their deductions and claim any refunds due. Mistakes in reporting or registration can lead to withheld payments or unexpected tax bills. That’s why it’s important to have a knowledgeable accountant by your side.
Our CIS tax returns in Ealing ensure you meet every deadline, submit every form correctly, and receive the maximum entitlement in rebates or credits.
