CIS Repayment & Rebate Claims: Recover Every Pound of Overpaid CIS Tax
CIS deductions are withheld at source regardless of your actual tax liability, which means many subcontractors are owed a refund once expenses and allowances are properly accounted for. We reconcile every deduction statement against your real tax position and file promptly so your rebate lands as early as possible.

Who We Are
Accountants who chase your CIS refund, not just file for it
Most subcontractors have 20% withheld from every labour payment, but their actual tax and National Insurance liability, once allowable expenses are deducted, is often lower. We reconcile every deduction statement you’ve received against your real income and expenses, then file your claim the moment it’s due rather than waiting for HMRC’s own timetable.

Early filing to accelerate refund timing within the tax year
Filing Early, Recovering Fast
The earlier we file, the earlier your refund arrives
CIS refunds are only processed once your Self Assessment is submitted and HMRC has verified the figures against your deduction statements, so a claim filed in April is generally paid far sooner than one filed in January. We prepare your return as soon as the tax year closes and your records are ready, rather than waiting until the filing deadline approaches.

Maximising Your Rebate
Claim every allowable expense before we calculate your refund
Tools, travel between sites, protective equipment, and subsistence are among the most commonly under-claimed expenses by subcontractors filing on their own, and each one directly increases the size of a legitimate refund. On a subcontractor billing £60,000 a year, correctly claimed expenses and allowances can turn a five-figure CIS deduction into a meaningful cash refund.
We review your full expense position before submitting any claim, ensuring nothing allowable is left unclaimed and your rebate reflects your genuine tax position.

Common Pain Points
What Slows Down or Shrinks a CIS Refund
Refund delays and under-claims are almost always avoidable with the right processes in place.
Missing or Incorrect Deduction Statements
Contractors don’t always issue statements on time, and rate errors can go unnoticed for months, distorting your true refund position.
Under-Claimed Allowable Expenses
Tools, travel, PPE, and subsistence are routinely under-claimed, leaving refunds smaller than they should be
Late Filing Delaying Cash Flow
Refunds only arrive after Self Assessment is submitted and processed, so late filing means late cash regardless of how large the refund actually is.
Deduction Statements Not Reconciled Against Income
Without matching every statement to actual payments received, discrepancies between what was deducted and what was declared can trigger HMRC queries.
Cash Flow Gaps Between Deduction and Refund
With tax withheld monthly but refunds only processed after the tax year ends, subcontractors can face a squeeze even while profitable on paper.

“I’d been under-claiming CIS repayments for two years without realising it. They found and recovered £14,000 within weeks of taking us on. Nobody had ever explained the scheme to me this clearly before.”
★★★★★
“We had no real idea which contracts were making money until they built us a proper job-costing system. Now we price the next tender based on actual data, not guesswork.”
★★★★★
“Every site brings its own VAT and SDLT questions, and they have never once been slow to answer. Switching from our old firm was the easiest financial decision we have made in years.”

FAQS
Commonly Asked Questions about CIS Repayment & Rebate Claims
Will I definitely get a CIS refund?
How long does a CIS refund take?
Timing depends on when your Self Assessment is filed and HMRC’s processing volumes; filing early in the tax year generally produces the fastest turnaround.
What expenses can reduce my tax and increase my refund?
Tools, protective equipment, travel between temporary workplaces, subsistence, and use-of-home costs are commonly allowable and frequently under-claimed.
Can I claim a refund for previous tax years?
Yes, in most cases going back up to four years, if the original deductions were not fully reclaimed at the time.
What if my deduction statements don't match what I actually received?
We reconcile every statement against your bank records and contractor confirmations to resolve discrepancies before filing.
Do materials count towards my CIS refund calculation?
No. CIS deductions apply to labour only, so materials costs are excluded from the deduction calculation from the outset.

We specialise exclusively in CIS reconciliation and refunds, so claims are maximised and filed early rather than left to HMRC’s own timetable.
