Accountants for Construction Businesses

Build a more profitable, better-structured construction business

Construction businesses deal with more moving parts than most. Subcontractors, CIS, VAT reverse charge, retentions, staged payments, supplier costs, payroll, vehicles, equipment and project delays can all affect your cashflow and profit.

Franks helps construction companies get clearer control of their numbers, so you can understand which jobs are profitable, plan for tax, manage cashflow and make better commercial decisions as the business grows.

Whether you are a contractor, specialist trade business, building company or construction firm with multiple teams, we can help you move beyond basic accounts and build stronger financial systems around your business.

Accounting support built around the way construction businesses work

Many construction businesses only find out how profitable a job was after it has finished. By then, the cash has gone, the costs have landed and the next project is already underway.

We help you get better visibility across the business, including project costs, labour, subcontractors, materials, VAT, tax and cashflow. This gives you a clearer picture of what is working, where profit is being lost and what needs to change.

Our support can include management accounts, tax planning, CIS, VAT, payroll, bookkeeping, limited company accounts and regular commercial advice.

More than year-end accounts

A lot of construction businesses only speak to their accountant when accounts or tax returns are due. That is too late to make meaningful changes.

Franks works with clients throughout the year, helping you understand the numbers while they can still influence your decisions.

Our support can include:

  • Limited company accounts
  • Corporation tax returns
  • Bookkeeping
  • VAT returns
  • CIS returns
  • Payroll
  • Management accounts
  • Cashflow forecasting
  • Tax planning
  • Director salary and dividend planning
  • Regular business advice
  • Software and reporting improvements

Common construction accounting problems we help solve

Unclear project margins

A job can look profitable on paper but still leave less cash than expected once labour, materials, subcontractors, equipment, delays and overheads are included.

We help you track costs more clearly, review margins and understand which types of work are genuinely profitable.

Cashflow pressure between jobs

Construction businesses often have money tied up in materials, labour, retentions and unpaid invoices. This can create pressure even when the business is busy.

We help you forecast cashflow, plan around tax bills and make sure you understand what money is actually available.

CIS and subcontractor payments

CIS can create admin pressure and cashflow issues if it is not managed properly.

We can help with CIS returns, subcontractor verification, deductions, monthly reporting and keeping your records in order.

VAT and domestic reverse charge

VAT in the construction sector can be complicated, especially where the domestic reverse charge applies.

We help you understand your VAT position, avoid common errors and make sure your systems are set up correctly.

Payroll, staff and site teams

As your business grows, payroll, pensions, staff costs and subcontractor arrangements become more important.

We help you manage payroll, understand employment costs and make better decisions around taking on staff, using subcontractors or building site teams.

Retentions and staged payments

Retentions and staged project payments can distort your view of cashflow and profit.

We help you build this into your reporting, so you are not making decisions based only on bank balance.

CIS Accountant

Get expert assistance with CIS (Construction Industry Scheme) compliance for contractors and subcontractors. Learn how CIS works, deductions, and tax support at Frank’s Accountants.

At Franks Accountants, we pride ourselves on being more than just accountants.

We are dedicated tax advisors with extensive experience in the construction industry.

Our team understands the unique financial challenges faced by contractors and subcontractors and is committed to helping you manage your finances effectively.

Construction Industry Scheme (CIS)

If you’ve been working in the construction industry for a while, you’re probably familiar with the Construction Industry Scheme (CIS). It’s an essential part of UK tax law designed specifically for contractors and subcontractors, ensuring that the correct amount of tax and National Insurance is paid to HM Revenue & Customs (HMRC).

CIS requires contractors to deduct money from subcontractors’ payments before they are made. These deductions are passed directly to HMRC and contribute towards the subcontractor’s tax and National Insurance obligations. Understanding how to navigate the complexities of CIS can be daunting, but with expert help from Frank’s Accountants, you can ensure full compliance while optimising your business’s tax position.

 

Understanding the rules of the CIS Scheme

The Construction Industry Scheme (CIS) is a set of rules introduced by HMRC for the construction sector, requiring contractors to deduct money from subcontractors to cover their tax and National Insurance contributions. The scheme is designed to reduce tax evasion in the construction industry by ensuring that subcontractors’ tax is paid upfront.

Whether you’re a contractor or a subcontractor, CIS can affect how you manage payments, tax deductions, and your overall cash flow. Our experienced accountants at Frank’s Accountants are here to help you manage CIS correctly and stay compliant with HMRC regulations.

Who Does CIS Apply To?

CIS applies to:

  • Contractors: Businesses or individuals paying subcontractors for construction work.
  • Subcontractors: Those carrying out construction work for a contractor.

Even if your main business is not in construction, you may still need to register for CIS if you regularly hire subcontractors for construction work.

 

CIS Deductions Explained

Under CIS, contractors are required to make deductions from subcontractors’ payments. These deductions, typically 20% or 30%, are sent to HMRC. The amount deducted depends on whether the subcontractor is registered under CIS.

  • Registered Subcontractors: Have 20% deducted from their payments.
  • Unregistered Subcontractors: Have 30% deducted until they register with HMRC.

These deductions are later credited towards the subcontractor’s annual tax bill.

This is accountancy as it should be done! Sam and the crew are as expert as it gets, always ready to offer support and expert advice and to assist in the seemingly endless interactions with HMRC. I really cannot recommend them highly enough. crawl on your bended knees over broken glass if you have to, but get to Franks accountants and leave them to take care of all the stuff you thought you understood ( but didn't!) Thank you all!
