Construction Industry

color1_icon_transparent_background.png

At Gaffney Business Solutions, we understand the financial realities of the construction industry. Construction businesses operate in a fast-moving environment where tight margins, complex supply chains, and strict regulatory requirements demand strong financial control. From managing subcontractors and materials to navigating CIS and VAT rules, maintaining accurate and compliant financial systems is essential to keeping projects running smoothly and profitably.

​

We work closely with contractors, subcontractors, and property developers to provide practical accounting and tax support tailored specifically to the construction sector. Our focus is on helping businesses maintain control over project finances, meet

regulatory obligations, and make informed decisions that support sustainable growth.

 

Construction companies face a number of industry-specific challenges, including managing subcontractor payments, tracking project costs in real time, complying with the Construction Industry Scheme (CIS), and ensuring that VAT is applied correctly under the domestic reverse charge rules. Our team provides specialist guidance across these areas, helping clients avoid costly compliance mistakes while improving financial visibility across projects.

​

Our services are designed to support construction businesses at every stage of their operations and include:

​

  • Preparation of annual accounts and statutory reporting

  • Construction Industry Scheme (CIS) registration, subcontractor verification, and monthly returns

  •  Subcontractor payroll processing and deduction statements

  • VAT compliance, including construction reverse charge rules

  • Job costing and project profitability analysis

  • Corporation tax compliance and capital allowances planning

  • Cashflow forecasting and financial planning for project pipelines

  • Financial oversight across multi-entity construction and property development structures

​

We understand that cashflow management is critical in construction, where payment cycles, retention arrangements, and project delays can all impact financial stability. Our role is to ensure that your financial systems provide clear, accurate information so you can manage these pressures with confidence.

​

At Gaffney Business Solutions, we aim to be more than just accountants. We work alongside construction businesses as trusted advisors, helping owners and management teams understand the financial performance of their projects while maintaining full compliance with HMRC requirements.

​

Our priority is to provide reliable financial guidance that allows you to focus on what matters most—delivering projects safely, efficiently, and profitably.

CIS Registration & Returns

Navigating the Construction Industry Scheme (CIS) requires diligence, accuracy, and timely action. We handle both contractor and subcontractor CIS registration with HMRC, ensuring you are set up correctly and fully compliant from day one. Our team prepares and submits CIS returns on your behalf, accurately calculating deductions and meeting all monthly filing deadlines. With our service, you avoid costly penalties and keep your status with HMRC in good standing. We also help you reclaim overpaid CIS tax, providing a smooth and timely refund process.

Monthly Deduction Statements

Issuing accurate monthly deduction statements is a legal obligation under CIS—and essential for maintaining trust with subcontractors. We produce clear, compliant statements that detail gross payments, deductions, and net payments due. Each statement is prepared promptly after payroll or invoice processing, ensuring your subcontractors have what they need to manage their own tax affairs. We also provide record-keeping and reporting tools to help you maintain HMRC-compliant documentation with precision and reliability.

VAT Reverse Charge Compliance

The VAT domestic reverse charge for building and construction services has added complexity to an already demanding sector. We help contractors and subcontractors understand and implement reverse charge rules accurately and on time. Our service includes reviewing contracts, issuing correct VAT invoices, updating accounting software, and reconciling VAT returns. We ensure you avoid costly errors, maintain accurate records, and stay fully compliant with HMRC’s MTD and reverse charge requirements.

Job Costing & Project Profitability

Understanding the true cost and profitability of your construction projects is critical. We provide accurate job costing analysis by tracking labour, materials, subcontractor fees, and overheads in real time. Our systems integrate with your bookkeeping software to deliver timely financial insights that help you manage budgets, improve pricing strategies, and boost profitability. Every report is prepared with precision and delivered on schedule, so you can make decisions with confidence.

Subcontractor Payroll

Processing payroll for subcontractors under CIS demands consistency and attention to detail. We manage the end-to-end payroll process, ensuring all deductions are calculated correctly and paid on time. Our service includes verifying subcontractor status with HMRC, issuing payslips, and making accurate RTI submissions. Whether you work with a small team or a rotating group of subcontractors, our streamlined system keeps you compliant, on schedule, and in control.

Construction Company Accounts

Construction businesses face unique accounting challenges—from stage payments and retention to work-in-progress valuation. We prepare detailed, fully compliant year-end accounts tailored to your business model. Our service ensures accurate recording of income and expenses, capital allowances, and job-related costs. We handle Companies House and HMRC filings with absolute precision and never miss a deadline. With our expert oversight, your accounts reflect true business performance and support long-term growth.

Contract Support

Strong contracts reduce disputes and ensure compliance. We assist with the drafting, review, and interpretation of subcontractor agreements and JCT contracts. Our team highlights tax implications, payment structures, and risk clauses, giving you the confidence that every agreement is commercially sound and legally robust. We deliver our reviews promptly, ensuring you meet project deadlines without compromising on contract quality. With our support, you can engage subcontractors and clients with clarity, compliance, and peace of mind.
