At ABM Chartered Accountants, based in Canary Wharf, London, we specialise in handling CIS returns, ensuring that contractors meet the CIS return deadline each month and stay compliant with the Construction Industry Scheme. Our service helps you submit CIS returns online, manage subcontractor deductions, and handle all reporting obligations.
The Construction Industry Scheme (CIS) requires contractors to deduct tax from payments to subcontractors and pass those deductions to HMRC. Each month, the contractor must file a CIS tax return, often called a CIS300 or monthly return, reporting all payments made and the deductions taken.
If you pay subcontractors for construction work, or you spend above the threshold in construction activities, you are classed as a contractor under CIS and must file monthly returns.
At ABM Chartered Accountants in Canary Wharf, London, we support contractors with full CIS return preparation, verification of subcontractors, and online submission to ensure compliance and reduce risk.
Handling CIS returns correctly offers multiple benefits. Working with expert CIS tax return accountants means your monthly submissions are accurate, you avoid heavy HMRC penalties for late or incorrect returns, and your subcontractors’ tax positions are protected.
We help you meet each CIS return deadline, file CIS returns HMRC compliant, and ensure your records are robust. With our London‑based service, you gain peace of mind knowing your contractor obligations are managed efficiently, freeing you to focus on your core construction business rather than complex monthly tax paperwork.
When selecting an accountant for your CIS returns or a CIS returns online service, look for professionals who understand the full scope of contractor and subcontractor obligations under CIS.

A CIS return is a monthly report that contractors must submit under the Construction Industry Scheme, showing payments made to subcontractors and tax deducted. You must file a CIS return if you are a registered contractor or deemed contractor under CIS rules.
The CIS return must be filed by the 19th of each month covering the previous tax month (which runs from the 6th of one month to the 5th of the next). Late filing can trigger automatic penalties.
Even if you had no subcontractor payments, you must submit a “nil return” for that month. Failing to submit a CIS return, even a nil return, can result in penalties.
You must keep details of each subcontractor payment, the deduction rate applied, verification reference numbers, subcontractor status, and the net amounts paid. Good record‑keeping supports the return and avoids compliance issues.
Incorrect deductions or mis‑filing can lead to penalties, interest charges and potential HMRC compliance checks. Using specialist support for your monthly CIS return reduces this risk and ensures correct processing.
Subcontractors typically do not submit the monthly CIS return; contractors do. However subcontractors need to ensure the deductions shown on CIS returns are reflected in their self‑assessment or company tax returns to reclaim any over‑deducted tax.
CIS deductions do not directly count as VAT input, but the payments and deductions affect your overall financial records. Accurate CIS returns ensure your accounts are correct and your self‑assessment or corporation tax filings reflect tax already deducted.
At ABM Chartered Accountants in Canary Wharf, London, we offer tailored monthly CIS return services, online submission support, subcontractor verification, deadline monitoring and comprehensive compliance support so you stay focused on your business.
