Glasgow's construction sector is in the middle of its biggest transformation in a generation, with the £1 billion Glasgow City Region City Deal funding major public realm and infrastructure works across the city centre while large-scale residential schemes reshape the Clyde waterfront. For CIS-registered subcontractors working on these projects, deductions of 20% are taken from the labour element of every payment before the money reaches your account, which means most subcontractors accumulate a refund entitlement across the tax year.

A Glasgow plasterer earning £38,000 gross from a contractor, with £400 in materials excluded from the deduction base, might have £7,520 deducted under CIS over the year. After claiming allowable expenses (tools, PPE, mileage at 55p per mile from 6 April 2026, use-of-home costs), the actual tax owed is typically far less than the amount deducted, generating a refund that averaged around £2,000 across Trade Tax Specialists' client base. We handle the Self Assessment return and the full reclaim process, from the first year through to the four prior years still open for recovery.

Note for Glasgow-based subcontractors: the CIS scheme operates identically across the whole of the UK, so your deduction rate, registration process and refund mechanics are the same as anywhere in England or Wales. However, because Scotland has its own Income Tax rate structure, the amount of tax you actually owe on your self-employed profits is calculated using Scottish Income Tax rates when HMRC processes your Self Assessment return. Your accountant must use the correct Scottish bands to compute the final liability, which affects the size of your refund.

The Glasgow construction scene

Glasgow's construction labour market operates across three distinct corridors in 2025 and 2026. The city centre Avenues programme, funded through the City Deal, has Rainton Construction on site at George Square (£20.5m contract, on site from May 2025, completing August 2026) alongside concurrent streetscape works on Cowcaddens Road, Duke Street, North Hanover Street and South Portland Street. These civils-heavy schemes draw heavily on groundworkers, civil engineers, bricklayers and landscaping operatives, many working as CIS-registered sole traders through the Avenues supply chain.

On the Clyde waterfront, Peel Waters' Glasgow Waters regeneration at Yorkhill Quay appointed Advance Construction Scotland in March 2026 on a £3.75m infrastructure contract (roads, utilities, public realm) due to complete December 2026, unlocking land for over 1,100 new homes. Further along the waterfront, GRAHAM Construction holds the Clyde Waterfront and Renfrew Riverside civils contract for Renfrewshire Council, with all sub-contract packages over £10,000 publicly advertised, making it an accessible pipeline for registered subcontractors in groundworks, scaffolding, temporary electrics and drainage.

The residential pipeline adds a third layer of demand. The Shawlands regeneration Phase 1 (329 apartments, £150m) and the Lancefield Quay area continue to draw joiners, plasterers, dryliners and painters-decorators. The Barbour ABI top-30 list for Glasgow in 2026 includes further student accommodation and build-to-rent schemes that sustain steady year-round demand for fit-out trades. In-demand trades across the city include groundworkers and civil engineers on the public-realm corridor, followed by joiners, dryliners and plasterers on the residential fit-out pipeline. Scaffolders are consistently busy across all project types.

CIS questions from Glasgow contractors

Do Scottish Income Tax rates affect my CIS refund in Glasgow?

Yes, but only at the Self Assessment stage. The CIS deduction rate itself (20% on your labour payments, or 30% if unregistered) is the same across the whole UK. The difference is that when HMRC calculates how much tax you actually owe, it applies Scottish Income Tax rates to your self-employed profits rather than the rUK rates. This can change the size of your refund compared with a subcontractor doing identical work in England. We file the correct Scottish Self Assessment return so you receive the right refund.

Can I claim a CIS refund even if I worked on multiple Glasgow sites?

Yes. CIS deductions from every contractor you worked for during the tax year are pooled on your Self Assessment return. We gather the payment and deduction statements from each contractor, total the deductions, offset your allowable expenses, and calculate the net refund due. Working across several Glasgow City Deal sites or the Clyde waterfront simultaneously is common and makes no difference to the reclaim process.

How much could a Glasgow subcontractor typically get back?

The average CIS refund we see is around £2,000, though the actual figure depends on your gross income, the labour-versus-materials split on your invoices, and the expenses you can legitimately claim (tools, PPE, mileage at 55p per mile from April 2026, use of home). We can look back up to four prior tax years if you have not claimed before.

Do I need to be based in Glasgow for you to handle my CIS return?

No. Trade Tax Specialists operates UK-wide. We work with subcontractors in Glasgow and across Scotland entirely remotely, using secure document sharing for your payment and deduction statements. You do not need to visit any office.

I am unregistered and have had 30% deducted. Can I still claim back?

Yes. Unregistered subcontractors pay 30% on the labour element instead of 20%, which typically means a larger refund once expenses and the personal allowance are applied at Self Assessment. We would also register you for CIS at the same time so future payments are deducted at 20%, saving you 10 percentage points on every labour invoice going forward.
