If you’re a subcontractor working under the Construction Industry Scheme, your contractor deducts 20% tax from every payment. Most subcontractors overpay — especially once tools, van costs, and work expenses are factored in. Tax2U recovers the difference and pays it directly to you.
Trustpilot ★★★★★ 4.7 / 5 Excellent Excellent 8,979+ reviewsThe Construction Industry Scheme (CIS) requires contractors to deduct income tax from payments made to subcontractors before handing the money over. That deduction goes directly to HMRC.
The problem is that the deduction rate — 20% for registered subcontractors, 30% for unregistered — is applied to your gross earnings, without accounting for your work expenses. Once tools, vehicle costs, clothing, and other allowable expenses are deducted, most subcontractors find their actual tax bill is far lower than the amount already paid.
The difference between what was deducted and what you actually owe is your CIS tax rebate. HMRC pays it back directly to you — but only if you file a Self Assessment tax return to claim it.
Deductions are applied to labour only (not materials). If you supply materials, these are excluded from the deduction calculation.
Quick Example
If you earned £30,000 as a CIS subcontractor, your contractor deducted £6,000 (20%). After allowable expenses of £8,000, your taxable income drops to £22,000. Your actual tax bill is roughly £2,486 — meaning you’re owed back £3,514.
Your rebate depends on your earnings, the CIS deductions made, and the expenses you can claim. These are indicative ranges based on typical subcontractor profiles.
Typical rebate after standard work expenses for lower-earnings subcontractors.
Average rebate for mid-range earners once tools, van, and trade expenses are claimed.
Higher earners with significant expenses can reclaim substantially more across multiple years.
* Figures are estimates only. Actual rebate depends on your specific earnings, expenses, and tax position. Tax2U will calculate your exact entitlement.

Got back over £3,200 I had no idea I was owed. The whole process was explained clearly and my account manager sorted everything. Will use every year from now on.
Dead easy. Sent over my CIS statements and they did everything else. Had the money in my account within 7 weeks. Brilliant service, no complaints.
Claimed for 3 years at once. Got nearly £8,000 back in total. Tax2U made it simple and my account manager was always available on WhatsApp. Highly recommend.
A CIS tax rebate is a refund of income tax that was deducted at source by your contractor under the Construction Industry Scheme. If your actual tax liability for the year is less than the amount deducted, HMRC owes you the difference — and we claim it back for you.
Any self-employed subcontractor who has had CIS deductions taken from their payments can claim a rebate. This covers all construction trades — bricklayers, electricians, plumbers, scaffolders, roofers, ground workers, and more.
The average CIS rebate is £2,000–£3,000 per tax year. The exact amount depends on your earnings, how much CIS tax was deducted, and the allowable expenses you can claim. Subcontractors with higher expenses often receive significantly more.
Yes — you can claim CIS rebates for up to 4 previous tax years. If you have never claimed before, Tax2U can submit backdated returns for all eligible years in one go, potentially recovering thousands in overpaid tax.
Once your Self Assessment tax return is submitted to HMRC, rebates are typically processed within 6–8 weeks. Tax2U monitors the progress and chases HMRC on your behalf if there are any delays.
Your CIS deduction statements (issued by your contractor) are the key document. If you have lost them, Tax2U can often obtain the figures directly from HMRC. Your account manager will advise exactly what’s needed once you apply.
Allowable expenses include tools and equipment, van and vehicle costs, work clothing, protective gear, phone bills, fuel, accommodation when working away, CSCS card fees, and professional subscription costs. Claiming all eligible expenses maximises your rebate.
