CIS and Construction Tax, Sorted in Birmingham

Birmingham’s construction sector is one of the busiest in the UK. HS2, major commercial development, the Commonwealth Games legacy infrastructure, and ongoing housing growth — there’s no shortage of construction work in the West Midlands. But busy doesn’t mean easy when it comes to tax: CIS compliance, reverse charge VAT, and the risk of leaving overpaid tax with HMRC all need professional handling.

Our Birmingham team handles CIS for contractors and subcontractors operating in the city and across the West Midlands — CIS300 returns, subcontractor verification, self-assessment for CIS refunds, and year-end accounts for construction limited companies.

From £190 + VAT for a CIS self-assessment return. Accurate, fast, compliant.

Who We Help in Birmingham

From CIS subcontractors on HS2 to construction companies across the West Midlands — we handle the CIS complexity.

CIS Subcontractors

CIS Contractors

CIS300 must be filed by the 19th of each month. Miss it and HMRC charges penalties. We manage verification, deduction calculations, CIS300 filing, and deduction statements for your subcontractors.

Construction Ltd Companies

Limited company accounts for construction businesses need capital allowances on plant and equipment properly calculated, reverse charge VAT handled correctly, and CT600 filed on time. We do all of it.

Sole Trader Builders

Working as a sole trader in construction? Your self-assessment return needs to account for CIS deductions, materials and fuel costs, tools and equipment, use of home, and van expenses. We claim everything.

Specialist Tradespeople

Electricians, plumbers, groundworkers, scaffolders — specialist trades often have high material costs and tool investments. We make sure those costs are properly accounted for and your tax bill reflects the real profit.

Why Birmingham Construction Businesses Need CIS Specialists

Birmingham is one of the UK’s largest construction markets. HS2 Curzon Street is the most high-profile project, but the development pipeline extends far beyond it — commercial development in the city centre, major residential schemes in Digbeth and the east of the city, and a constant flow of infrastructure and refurbishment work across the West Midlands.

CIS subcontractors across Birmingham, Solihull, and the West Midlands are leaving money with HMRC every year. Contractors deduct CIS tax at 20% or 30% from payments, but the actual tax due on profits is usually much less. The refund comes via self-assessment — but only if you file. We file CIS returns quickly, claiming every allowable expense.

The construction industry reverse charge has caught out Birmingham businesses of all sizes. Apply it when you shouldn’t, or miss it when you should, and you’ve got a VAT problem that’s expensive to resolve. We handle VAT for construction businesses in Birmingham correctly — right scheme, right treatment, right from the start.

Subcontractor compliance is tighter than ever. HMRC actively investigates Birmingham construction businesses for misclassification, late CIS300s, and verification failures. We make sure everything is in order — verified, filed, and documented.

Frequently Asked Questions

Common questions about CIS and construction accounting in Birmingham.

How much does a CIS tax return cost in Birmingham?

CIS self-assessment returns start from £190 + VAT. The exact fee depends on income sources, expenses claimed, and complexity. We always quote a fixed fee upfront — and most subcontractors find the cost is far less than the refund we generate.

Can I meet to discuss my CIS situation at your Birmingham office?

Yes. Our Birmingham office is on Colmore Row, B3 2BJ. We’re happy to meet face-to-face or handle everything remotely if you’re on-site during the day.

How much CIS tax can I get back in Birmingham?

It depends on your income, expenses, and the deduction rate applied. Most CIS subcontractors are deducted 20% or 30% on gross payments, but the actual tax on profits after expenses is usually significantly less. We calculate the expected refund before we start.

What expenses can I claim as a CIS subcontractor?

Materials purchased, fuel, van running costs, tools, protective clothing, phone bills, accountancy fees, and use of home where applicable. We review your expenses thoroughly to claim everything you’re entitled to.

What is the construction industry reverse charge and does it apply to me?

The CIS domestic reverse charge means the customer accounts for VAT rather than the supplier — for certain construction services between VAT-registered businesses. We apply it correctly so your VAT treatment is right from the start.

What is a CIS300 return and who files one?

CIS300 is the monthly return filed by contractors listing subcontractors paid, amounts, and deductions. It must be filed by the 19th of the following month. Late filing triggers automatic HMRC penalties. We file on time, every month.

Can you help if I haven't filed CIS self-assessment for several years?

Yes. We bring returns up to date, claim the refunds you’re owed for multiple years, and minimise any penalties through voluntary disclosure with HMRC.

Should I operate as a sole trader or limited company in Birmingham construction?

It depends on income level, risk exposure, and tax position. We assess your specific situation and give you a clear comparison — including how CIS rules differ for sole traders vs. limited companies — before you decide.
