CIS accountants in Birmingham

Price range: ££

Birmingham is in the middle of the most intense phase of construction investment in its modern history. HS2 Curzon Street station is rising from its foundations in the city centre, the £1.9 billion Smithfield regeneration is beginning enabling works, and a pipeline of residential and commercial schemes is responding to the city's population growth and post-Commonwealth Games momentum. Every trade on every one of these schemes operates under the Construction Industry Scheme, and the scale of the projects means CIS deductions are accumulating in large volumes. A Birmingham groundworker with £41,000 in gross CIS labour income in 2025/26 will have had £8,200 deducted at the registered 20% rate before expenses reduce the tax bill further, and in most cases a significant refund is owed after self-assessment.

We act for subcontractors across Birmingham and the wider West Midlands conurbation including Wolverhampton, Coventry, Dudley and Walsall. Our service is entirely remote and most new clients receive their first refund within 8 to 12 weeks of our first contact. Every new engagement includes a check on back-year entitlement covering up to four prior tax years, which for subcontractors who have not previously used a CIS accountant can produce a combined repayment well above the illustrative £2,000 annual average.

The Birmingham construction scene

The dominant employer of construction labour in Birmingham right now is HS2. The Mace Dragados joint venture is the principal contractor on the Curzon Street terminus station, which at 500 metres long and 70 metres wide will be the largest new intercity terminus built in the UK since the Victorian era. Piling and foundation works delivered 2,000 concrete piles in 2025; façade works, concourse steelwork and roof construction are progressing through 2025 and 2026 on a programme that will carry through to fit-out completion in 2028. The station supports over 1,000 construction jobs during its main construction phase, drawing civil engineers, steelwork erectors, groundworkers, concrete frame contractors and M&E trades from across the West Midlands supply chain.

Adjacent to Curzon Street, Birmingham City Council and its partners are progressing the £1.9 billion Smithfield regeneration on 17 hectares of city-centre land formerly occupied by the wholesale markets. Lendlease, in joint venture with The Crown Estate, is the developer and delivery partner; a £173 million grant unlocked in mid-2025 is funding enabling works on the new Bull Ring Markets, up to 3,500 homes, commercial and cultural space, and two major public squares. Construction is scheduled to begin in earnest in early 2026, extending the demand for groundwork, frame, M&E and finishing trades well into the 2030s.

Beyond the two headline schemes, Birmingham's residential pipeline is substantial. The city council's 2026 high-rise masterplan proposes significant further development in the Eastside and Digbeth corridors, and the Jewellery Quarter continues to attract residential conversion and new-build schemes served by local bricklaying, plastering and roofing subcontractors. The A38 and M6 corridors function as the main construction supply arteries, with many West Midlands trades commuting from the Black Country and Coventry corridor.

Major construction projects in Birmingham

HS2 Birmingham Curzon Street station (Mace Dragados JV)

Mace Dragados joint venture, with Keltbray piling and MPB Structures on the substructure, is delivering the 500-metre HS2 terminus. Façade construction and concourse steelwork started in 2025 with the roof and internal fit-out progressing through 2026 to 2028; the project supports over 1,000 construction jobs.

Smithfield Birmingham (Lendlease / The Crown Estate)

A £173 million grant approved in 2025 unlocked enabling works on the £1.9 billion Smithfield regeneration: 17 hectares of former wholesale market land being redeveloped by Lendlease and The Crown Estate into up to 3,500 homes, new market buildings, offices, two public squares and a city park, with main construction beginning in early 2026.

Eastside and Digbeth residential pipeline

The city council's 2026 high-rise masterplan and ongoing conversion activity in Digbeth are generating a steady flow of residential schemes: concrete-frame, bricklaying, internal fit-out and roofing trades are active across multiple simultaneous sites in these inner-city neighbourhoods.

West Midlands Metro extension works

Ongoing Metro tram network extensions across the West Midlands are generating civils, rail infrastructure and highway reinstatement work for groundworkers, bricklayers and civil engineering subcontractors across the conurbation.

CIS questions from Birmingham contractors

Do I need a CIS accountant in Birmingham to claim my refund?

No. We act for Birmingham and West Midlands subcontractors entirely remotely. Your CIS deduction statements and expense records come to us digitally and we file your self-assessment return online. There is no need for a local office visit and we cover the full West Midlands including Wolverhampton, Coventry, Dudley, Walsall and Solihull.

How much CIS refund does a Birmingham subcontractor typically get?

The illustrative average is around £2,000 for a registered subcontractor in a standard year. On large schemes such as HS2 Curzon Street, where materials such as concrete, steel and plant are often contractor-supplied, a higher proportion of earnings may be labour and therefore subject to the 20% deduction, increasing the potential refund once allowable expenses are applied. First-time clients with unclaimed back years often receive substantially more.

Does working on HS2 Curzon Street or Smithfield mean CIS applies?

Yes. Both are standard CIS-qualifying construction contracts. If Mace Dragados or their sub-agents deducted 20% from your labour payments, those deductions count toward your refund calculation via self-assessment. We pull together all the deduction statements from a project, however many contractors were involved.

What expenses can a Birmingham CIS subcontractor claim?

Mileage at 55p per mile from 6 April 2026 is usually the largest expense. Tools, PPE, work clothing and the business proportion of your phone are also allowable. If you commute to Birmingham city-centre sites from the Black Country or Coventry, the daily mileage figure adds up quickly across a full year and increases your refund significantly.

I have not claimed a CIS refund for three or four years. Is it too late?

No. HMRC allows self-assessment refund claims going back four complete tax years. If you are a registered subcontractor who has had 20% deducted and has not filed returns, you may have four years of refunds sitting at HMRC. We handle the catch-up filing as a standard service for new clients.
