CIS Tax Returns for Construction Contractors
Managing CIS tax returns as a contractor requires a clear understanding of HMRC rules, monthly obligations, and subcontractor responsibilities. The Construction Industry Scheme involves strict compliance, and errors can lead to penalties or delayed submissions.
Specialist CIS accountants support contractors by managing the full CIS tax return process, from HMRC registration to accurate monthly reporting. This includes verifying subcontractors, calculating correct deductions, and submitting CIS returns on time.
Contractors are responsible for deducting the correct tax from subcontractor payments and reporting these figures to HMRC every month. Each reporting period also requires issuing CIS deduction statements to subcontractors. Professional support reduces administrative burden, ensures accuracy, and keeps your CIS tax returns fully compliant
CIS Tax Returns for Construction Subcontractors
CIS tax returns are equally important for subcontractors, whether operating as sole traders or limited companies. CIS rules can be complex, and staying compliant is essential to avoid penalties and missed tax refunds.
Self-employed subcontractors must retain CIS deduction statements and submit an annual Self Assessment tax return to report income already taxed at source. Registered subcontractors typically have 20% deducted, while unregistered subcontractors face 30% deductions, often resulting in refundable overpayments.
Limited company subcontractors report CIS deductions through their PAYE scheme, with amounts offset against Corporation Tax liabilities at year-end. Specialist CIS accountants ensure deductions are correctly applied, records are accurate, and CIS tax returns reflect the correct tax position.

EXCELLENT Based on 270 reviews Posted on Steve haywoodTrustindex verifies that the original source of the review is Google. I've used Accotax for a number of years now to complete my annual tax returns which I always find extremely stressful as I'm so disorganised and can never find important stuff. I'm consequently always last minute. This year I was worse than ever but Saad was extremely patient. He sent constant reminders to encourage me. Eventually I got the information together in my very haphazard fashion and Saad pieced it together very quickly and efficiently. I've even considered getting started on next year's figures!Posted on Eco Glitter FunTrustindex verifies that the original source of the review is Google. Have been using Accotax for over year years for my personal tax return. Muhammad Saifullah Is especially professional and helpful. Would recommmedPosted on Tom WatsonTrustindex verifies that the original source of the review is Google. Saad is patient, polite, helpful, professional and thorough. Highly recommended.Posted on pal mrTrustindex verifies that the original source of the review is Google. I honestly regret using this accounting service. What I got was a mix of incompetence, poor communication, and a complete lack of professionalism. Basic accounting tasks were mishandled, deadlines were missed, and I constantly had to follow up just to get simple answers. It felt like I knew more about my own books than the people I was paying to manage them. Mistakes were brushed off instead of corrected, and accountability was nonexistent. If you value accuracy, reliability, or peace of mind, this is not the service for you. There are far better options out there. I strongly recommend looking elsewhere before wasting your time and money.Posted on Martin SimsonTrustindex verifies that the original source of the review is Google. Waqas Sagar was very helpful. He refunded my consultation fee as we did not speak for long. The process of setting up a video appointment and connecting was seamless.Posted on Ayotunde RufaiTrustindex verifies that the original source of the review is Google.
