How much CIS tax rebate can I get back?

The amount varies based on your earnings and expenses, but the average CIS tax rebate for Tax2u customers is £2,659. We use expert accountants to ensure you claim all allowable expenses to maximize your refund.

How long does it take to get a CIS tax refund from HMRC?

Once Tax2u submits your return, it typically takes HMRC 2-3 weeks to process it. We offer a fast-track service that aims to have your tax return submitted to HMRC within 48 hours of receiving your documents.

What if I don’t file my CIS tax return?

Failing to file can result in automatic HMRC penalties starting at £100. Furthermore, without filing, you cannot claim back the 20% or 30% tax deductions made by your contractor, which often results in you overpaying tax.

How much does Tax2u charge for a CIS tax return?

Our fixed-fee CIS tax return service starts from £135 + VAT. Unlike many other providers, we do not take a percentage of your total tax rebate, ensuring you keep more of your hard-earned money.

What expenses can CIS subcontractors claim?

You can claim for allowable business expenses including travel costs (fuel/mileage), tools and equipment, protective clothing (PPE), professional insurance, and even a portion of your phone and internet bills used for work.

What CIS Subcontractors Say

Real reviews from construction workers who've claimed their CIS rebate with Tax2U.

"Got back over £3,000 I didn't even know I was owed. They sorted everything online — I just answered a few questions and uploaded my CIS statements. Brilliant service."

D. HarrisonGroundworks Contractor

"Tried to do my own CIS rebate for two years and left money on the table. Tax2U claimed back expenses I hadn't even thought of. The whole process was done in days."

S. PatelElectrical Subcontractor

"Work across four different contractors so my CIS was complicated. They handled all of it, sent me a clear breakdown to approve, and the rebate hit my account a few weeks later."

CIS Rebate FAQ

Common CIS Rebate Questions

How much CIS tax can I claim back?▾

The average CIS rebate Tax2U processes is £2,659 — though the actual amount depends on your earnings, the CIS deductions taken and your allowable expenses. Most subcontractors are deducted more tax than they owe because expenses like materials, fuel and equipment are not factored in at the point of deduction.

What is a CIS tax rebate?▾

Under the Construction Industry Scheme (CIS), contractors deduct tax at 20% or 30% from subcontractor payments before paying HMRC. Many subcontractors overpay because their allowable expenses are not deducted at source. Filing a Self Assessment return allows you to claim back the difference — that refund is your CIS rebate.

Can I claim back CIS deductions on materials and expenses?▾

Yes. Allowable expenses that reduce your tax liability include materials you have paid for yourself, fuel for business journeys, protective clothing and PPE, tools and equipment, and the business use of a van. These reduce your taxable income, which is why most CIS workers receive a rebate when they file.

How far back can I claim a CIS rebate?▾

HMRC allows claims for overpaid tax for up to four prior tax years. In the 2025–26 tax year you can still claim for 2021–22, 2022–23, 2023–24 and 2024–25. Years before this are time-barred. If you have not filed in previous years, it is worth acting now before older years close.

How long does a CIS rebate take after filing?▾

Once your return is filed, HMRC typically processes CIS rebates within 4 to 8 weeks, though timing varies. Tax2U submits returns promptly and monitors any HMRC follow-up so you are not left chasing.

Do I need to be registered under CIS myself?▾

No. Your contractor registers you with HMRC under CIS when they make deductions from your pay. If you have had tax deducted under CIS, you are within the scheme. Tax2U handles the Self Assessment registration and filing process on your behalf.
