Take Control of Your Construction Business Finances

The construction industry presents unique financial and compliance challenges. From managing subcontractor payments and CIS obligations to overseeing payroll, VAT and project profitability, staying on top of your finances is essential for long-term success.

At Accountant Bookkeeping Ltd, we provide specialist bookkeeping, accounting and compliance support tailored to contractors, subcontractors and construction businesses across the UK.

Why Construction Businesses Need Specialist Accounting Support

Construction accounting is more complex than standard small business bookkeeping. Projects often run over several months, costs can fluctuate significantly, and businesses frequently work with a mix of employed staff and subcontractors paid under the Construction Industry Scheme.

Without accurate, up-to-date financial records, it becomes difficult to understand true project profitability, manage cash flow between stage payments, and stay on top of CIS and VAT obligations.

Specialist construction bookkeeping and contractor accountant support helps you:

• Track income and costs by project or contract
• Maintain accurate CIS records for subcontractors
• Manage VAT correctly, including the domestic reverse charge
• Plan payroll around variable workloads
• Reduce the risk of HMRC penalties for late or incorrect returns

Understanding the Construction Industry Scheme (CIS)

What Is CIS?

The Construction Industry Scheme is a set of HMRC rules that govern how payments to subcontractors in the construction industry are taxed. Under CIS, contractors deduct money from a subcontractor's payments and pass it to HMRC as an advance payment towards the subcontractor's tax and National Insurance.

CIS Registration

Contractors who pay subcontractors for construction work must register with HMRC as a contractor. Subcontractors are not required to register, but those who do not register have CIS deductions taken at a higher rate than registered subcontractors.

Verifying Subcontractors

Before making the first payment to a new subcontractor, contractors must verify their details with HMRC to confirm the correct deduction rate to apply, which may be the standard rate, the higher rate, or gross payment status.

Monthly CIS Returns

Contractors must submit a CIS return to HMRC every month, reporting payments made to subcontractors and the deductions taken. Returns are required even in months where no subcontractors have been paid, and late or incorrect returns can result in penalties.

CIS Services We Provide

Our CIS services for contractors and subcontractors include:

• CIS registration for contractors and subcontractors
• Verifying subcontractors with HMRC
• Preparing and submitting monthly CIS returns
• Issuing CIS payment and deduction statements
• Reconciling CIS deductions against tax liabilities
• Advising on gross payment status applications

Construction Bookkeeping and Contractor Accounting

Accurate, project-based bookkeeping gives construction businesses clear visibility over cash flow, profitability, and outstanding costs. Our construction bookkeeping services include:

• Recording income and expenses by project or contract
• Reconciling bank accounts and supplier invoices
• Tracking retention payments and stage payments
• Managing subcontractor invoices and CIS deductions
• Producing management reports to support business decisions

Working with a dedicated contractor accountant or subcontractor accountant means your records stay organised throughout the year, rather than being pieced together at year end, which supports better decision-making and smoother tax compliance.

Construction Payroll

Many construction businesses employ a combination of permanent staff and subcontractors, which adds complexity to payroll administration. Our construction payroll services cover:

• Processing payroll for employed staff, including PAYE and pension auto-enrolment
• Managing CIS deductions for subcontractors alongside standard payroll
• Issuing payslips and year-end reporting
• Advising on holiday pay and statutory payments for construction workers

VAT for Construction Businesses

VAT Registration

Construction businesses must register for VAT once their taxable turnover exceeds the current VAT threshold, and may choose to register voluntarily below this level in some circumstances.

VAT Domestic Reverse Charge

The VAT domestic reverse charge applies to most construction services supplied between VAT-registered businesses within the Construction Industry Scheme. Under the reverse charge, the customer accounts for the VAT on the supply instead of the supplier, which changes how invoices should be prepared and how VAT returns are completed.

Getting the reverse charge wrong can lead to incorrect VAT returns and cash flow issues, so specialist advice is recommended for contractors and subcontractors affected by these rules.

Our VAT Services

We help construction businesses with:

• VAT registration and scheme selection
• Correct application of the domestic reverse charge
• Preparing and submitting VAT returns
• Making Tax Digital compliance for VAT
