Accountants and Tax Advisors For Contractors
We provide detailed CIS accounting services to help contractors and subcontractors with these complex requirements. HMRC created the Construction Industry Scheme (CIS) to control taxation when contractors hire subcontractors. Contractors must deduct money from payments and pass it to HMRC. Our services simplify your tax compliance obligations.
Accounting, Tax and Advisory For CIS Contractors
Contractors face statutory obligations that just need precision and timeliness. We handle these requirements in a systematic way and remove the administrative burden from your operations while ensuring full compliance with HMRC regulations.
Monthly CIS returns management
Every contractor must submit monthly returns to HMRC by the 19th of the following month. These returns detail all subcontractor payments, deductions made and verification references for the previous tax month. We prepare and submit these returns and extract data from your payment records. We cross-check figures before submission.
Subcontractor verification and registration
Before making any payment to a new subcontractor, you must verify them with HMRC. We complete this verification process on your behalf. We gather the details that include the subcontractor's Unique Taxpayer Reference and National Insurance number for sole traders or company registration details for limited companies.
Deduction calculations and statements
Calculating CIS deductions requires separating materials costs from labor charges and then applying the correct percentage to the labor portion only. We perform these calculations for every payment to ensure subcontractors receive accurate net amounts and HMRC receives proper deductions. Our processes account for VAT exclusions and materials documentation.
Our Accounting Services for CIS Contractors & SubContractors
We deliver end-to-end CIS accounting solutions that address every aspect of construction tax compliance, from original setup through ongoing coverage obligations.
HMRC contractor registration
Registration as a contractor follows the same process as setting up a new employer. We guide you through the registration steps and make sure you provide accurate information while avoiding common setup errors. HMRC will establish your Contractor Scheme and PAYE Scheme if requested, then supply your employer PAYE reference number. Our team completes registrations quickly using agent access to HMRC software.
Bookkeeping
Construction bookkeeping often becomes disorganized when businesses scale quickly. New subcontractors may be added without proper verification. We maintain structured bookkeeping, subcontractor payment reconciliation and organized coverage systems that support ongoing HMRC compliance. This has tracking deductions and will help you prepare reclaim evidence to reduce overpaid tax where applicable.
Full CIS compliance support
We run your CIS process end-to-end and keep submissions accurate. All PAYE tax and National Insurance contributions must be paid by their due dates. All CIS deductions and VAT liabilities must also be settled on time. We track deduction statements and support reclaim workflows. Compliance monitoring keeps records, deadlines and status checks organized to lower compliance risk.
PAYE services
Many construction businesses operate both PAYE and CIS at the same time because they employ staff while engaging subcontractors. We provide integrated CIS accounting and payroll solutions that make sure employees receive correct treatment under PAYE while subcontractor payments follow CIS rules.
Monthly HMRC returns
We submit monthly returns to HMRC with accurate labor and deduction treatment. We meet the 19th deadline consistently. Our detailed CIS accounting services handle every compliance requirement. This partnership protects you from penalties that can get pricey while ensuring you never get in trouble. .
VAT returns and advice
VAT compliance for construction firms requires understanding the domestic reverse charge alongside standard VAT obligations. We prepare quarterly VAT returns and manage reverse charge procedures. We can help you move to monthly returns using your online VAT account. Our integrated approach will give VAT that is always compliant.

How We Help CIS Sub Contractors
Subcontractors remain responsible for paying correct tax and National Insurance even when contractors deduct amounts throughout the year. We help you direct these obligations while maximizing refunds and maintaining compliance with HMRC requirements.
- CIS tax return preparation
- Reclaiming CIS overpayments
- Applying for gross payment status
- Self-assessment tax return support
You must submit your Self Assessment return at the end of each tax year. Record the full amounts on your invoices as income and any contractor deductions in the CIS deductions field. We prepare these returns with accuracy and extract data from your payment and deduction statements. To cite an instance, contractors must provide these monthly statements within 14 days of each tax month. We track them in a systematic manner. HMRC calculates your final tax bill and subtracts deductions already made. Then proper recording becomes the difference between receiving your entitled refund or facing unexpected payments.
Most subcontractors overpay tax under CIS because deductions apply to gross income without accounting for your personal allowance or business expenses. We've found that 95% of CIS customers receive tax refunds, with average values reaching £1,705 per year. Our process identifies all allowable expenses such as mileage and fuel, tools and PPE, accommodation costs and trade insurance. These deductions reduce your taxable profit, which explains why refunds are so common. HMRC repays the excess once we submit your complete return if you paid too much through CIS deductions during the tax year.
We handle your gross payment status application and gather documentary evidence to demonstrate you meet turnover tests. Applications require invoices and payment statements, plus bank statements showing corresponding receipts. Processing times have increased, and problems with supporting evidence cause delays. We ensure your application has complete information from the outset, as failures result in HMRC rejection.
We manage your entire Self Assessment process, from gathering CIS deduction statements to submitting returns by the 31 January deadline. Our team handles HMRC queries on your behalf and chases delayed refunds. Limited company subcontractors face different requirements and claim CIS deductions through monthly payroll schemes via Employer Payment Summary filings. We maintain records using form CIS132 or digital systems and keep everything organized for at least three years.
