SPECIALIST CONSTRUCTION ACCOUNTING

Construction accounting works best when the numbers are connected

Construction businesses rarely have one isolated accounting issue. CIS deductions, subcontractor payments, VAT, payroll, materials, project costs and cash flow all influence one another.

ATA helps bring those areas into one structured accounting process, so you can understand what is happening across the business rather than looking at each return or transaction in isolation.

01

CIS & subcontractors

Contractor records, subcontractor verification, deductions and monthly CIS returns need to remain accurate and organised.

02

VAT & Reverse Charge

Domestic Reverse Charge VAT and normal VAT treatment need to be understood alongside the underlying construction transactions.

03

Payroll & labour costs

Employees, subcontractors and changing labour requirements can have a significant effect on reporting, compliance and cash flow.

04

Project costs & cash flow

Better bookkeeping can give clearer visibility over margins, materials, outstanding customers, supplier balances and future cash requirements.

Specialist Construction Accountants for Contractors & Subcontractors

CIS accounting for contractors and subcontractors

Keep CIS Compliance Under Control

Managing subcontractors brings additional responsibilities under the Construction Industry Scheme. From verifying subcontractors and applying the correct deduction rate to monthly CIS returns and payment statements, accurate records are essential.

CIS support can include:

  • CIS registration support
  • Subcontractor verification
  • Monthly CIS300 returns
  • CIS payment and deduction statements
  • Recording labour and subcontractor costs
  • Reconciling CIS deductions with accounting records
  • Correcting discrepancies in CIS records
  • Contractor and subcontractor bookkeeping
  • Maintaining supporting CIS records

A well-managed CIS process helps reduce filing errors, keeps subcontractor records organised and makes it easier to reconcile deductions with the underlying accounts.

Keep Track of CIS Tax Deducted From Your Income

Subcontractors can have CIS tax deducted before they receive payment, which means the amount arriving in the bank may be significantly lower than the value invoiced. Without accurate records, it can become difficult to reconcile turnover, deductions and amounts received.

Support can include:

  • Recording gross sales before CIS deductions
  • Reconciling CIS deduction statements
  • Matching invoices to payments received
  • Tracking CIS tax suffered
  • Identifying missing or inconsistent deduction records
  • Maintaining records for tax returns and year-end accounts
  • Reviewing CIS deduction balances
  • Supporting repayment or offset positions where applicable

Properly recording the gross income, CIS deducted and net payment received helps ensure that turnover is not understated and that deductions are properly reflected in the accounting and tax records.

Domestic Reverse Charge VAT Without the Confusion

VAT in construction can become more complicated where services fall within the Domestic Reverse Charge. The supplier may need to issue an invoice without collecting the VAT in the usual way, while the customer accounts for the VAT through its own VAT return.

Support can include:

  • Reviewing construction transactions for VAT treatment
  • Domestic Reverse Charge bookkeeping
  • Correct recording of sales and purchase invoices
  • VAT return preparation and reconciliation
  • Separating standard VAT and reverse-charge transactions
  • Checking accounting software VAT codes
  • Reviewing subcontractor and contractor invoices
  • Maintaining appropriate supporting records
  • Identifying transactions requiring further VAT review

Getting the VAT treatment right at transaction level makes the VAT return easier to prepare and helps prevent errors accumulating within the accounting records. See HMRC Guidance on domestic reverse charge

Know Which Construction Jobs Are Making Money

A healthy bank balance does not necessarily mean every project is profitable. Labour, subcontractors, materials, plant, retentions and delayed customer payments can make it difficult to see the true financial performance of individual jobs.

KEY AREAS:

  • Labour and subcontractor costs
  • Materials and supplier expenditure
  • Project and job costs
  • Gross margins by project
  • Work in progress
  • Customer balances and aged debt
  • Supplier balances
  • Retentions

WHY CONSTRUCTION BUSINESSES WORK WITH ATA

Accounting built around how construction businesses actually operate

Construction businesses need more than basic compliance. We try to connect CIS, VAT, payroll, bookkeeping and project information so that the accounting process reflects what is really happening across the business.

01

We understand the construction workflow

CIS, subcontractors, payroll, materials and project costs all interact. We aim to keep those areas connected rather than treating each one separately.

02

CIS and VAT are kept under control

From CIS records and monthly returns to construction accounting support and Domestic Reverse Charge VAT, we help keep the compliance process organised.

03

Better visibility over project numbers

Structured bookkeeping and reporting can help you understand project costs, margins, customer balances, supplier balances and cash-flow requirements more clearly.

04

Support that can grow with the business

Whether you are managing a small subcontractor base or developing a larger operation, the accounting process can evolve as your reporting and compliance needs become more complex.
