CIS Deductions Suffered: Reclaiming Them Correctly at Year End



 

If you are a subcontractor in construction, you are used to watching a chunk of your invoice disappear before it reaches you. Contractors deduct 20% from labour payments when you are registered for the Construction Industry Scheme, or 30% if you are not. Those deductions are not lost money: they are advance payments of your tax. But reclaiming them correctly at year end is where subcontractors, and their accountants, most often go wrong.

How deductions suffered actually work

Every time a contractor pays you, they must give you a payment and deduction statement showing the gross amount, the materials element, and the tax deducted. HMRC also receives the same information through the contractor's monthly return. The deduction is a credit against your final tax bill. If the total deducted during the year exceeds what you owe, the excess comes back to you. If it falls short, you pay the difference. The system is straightforward in principle; the problems are all in the evidence.

Companies: offset during the year, reclaim at year end

Limited companies do not wait for year end to use their CIS deductions. During the year, a company can set the deductions it has suffered against its PAYE, National Insurance and Construction Industry Scheme liabilities for the same tax month, claimed through the Employer Payment Summary. This keeps cash flow moving instead of trapping a year's worth of deductions until the corporation tax return is filed. Any surplus that remains after the final offset for the year is then reclaimed through the company tax return, and HMRC repays it once the return has been processed. Two points matter here. First, the set-off rules were tightened from April 2024, so claims now need to be evidenced and HMRC can block set-off where the figures do not stack up. Second, keep the contractor statements for every deduction: a claim without evidence is the fastest route to a rejected repayment.

Sole traders and partnerships: it goes through self-assessment

If you trade as a sole trader or partnership, there is no monthly set-off. Your CIS deductions for the tax year are entered on your self-assessment return, and HMRC credits them against the tax and National Insurance you owe. Overpayments are repaid after the return is processed. The common mistake is entering the wrong figure, usually the gross payments rather than the deductions, or double-counting a deduction that also appears on a different return. Work from the contractor statements, add them up yourself, and keep them for at least three years after the end of the tax year, because HMRC will ask for them when it queries a repayment.

The evidence file that protects every claim

Whether you are a company or a sole trader, the year-end routine starts with the same file: every payment and deduction statement for the year, matched to your sales invoices, with materials separately identified. Materials are not subject to CIS deductions, so a contractor who deducts from the materials element has made an error worth correcting before the return goes in. Reconcile the statements to your bank receipts too. If a statement is missing, chase the contractor now, not when HMRC opens an enquiry. Keep verification details and any gross payment status correspondence in the same file.

Common reclaim errors to avoid

The most expensive error is claiming deductions you cannot evidence, which invites HMRC to disallow the whole repayment and open the books more widely. Next comes timing: companies claiming a set-off in a month before the deduction was actually suffered, which the tighter post-2024 rules are designed to catch. Sole traders frequently forget that CIS deductions on their return must match the tax year in which they were suffered, not the accounting year the invoice relates to. And almost everyone underestimates how long HMRC takes to process a repayment claim without clean records attached. A tidy evidence file is worth real money at year end.

Make the reclaim routine, not a scramble

CIS reclaims reward one habit above all: collecting and filing the statements every month as they arrive. Do that, and the year-end return is arithmetic. Leave it to March, and it is detective work. If the monthly filing keeps slipping, hand the routine to specialists: the team at Finex Outsourcing runs the CIS paperwork, PAYE set-offs and reconciliations through the year, and their corporation tax and self-assessment support handles the final reclaim properly. Deductions suffered are your money. Claim them like it.

The contractor's record-keeping system: what survives an HMRC check

Image
Contractors face two kinds of HMRC scrutiny: the IR35 status enquiry, and the routine check of the company accounts. Both are survived the same way: with records that are complete, contemporaneous and organised. Here is the system. Contracts and status evidence first For IR35, the contract is the starting point but never the whole story. Keep every version of every contract, the working practices evidence that backs up your status determination (who controls the work, substitution clauses exercised or available, financial risk taken), and any CEST outputs or professional status reviews. HMRC looks at reality, not paperwork, so evidence of how you actually worked matters more than what the contract says. The company books, kept properly Bank feeds reconciled monthly. Every expense with a receipt, photographed at the time, not reconstructed in January. Dividend vouchers and board minutes for every dividend. Payroll records including P60s.

SEIS and EIS Basics: Tax Reliefs That Help Startups Raise Money

By John Thomas, Senior Accountant For early-stage UK companies, the Seed Enterprise Investment Scheme and the Enterprise Investment Scheme are the two most powerful fundraising tools available. They offer investors generous income tax relief, capital gains exemptions and loss relief, which makes investing in a risky startup significantly less risky after tax. If you are raising money, understanding these schemes is not optional. Here is how they work. What the schemes are SEIS is aimed at very early-stage companies raising their first external investment. EIS is for slightly more established young companies raising larger rounds. Both work the same way in principle: qualifying investors who buy new shares in a qualifying company get income tax relief on the amount invested, pay no capital gains tax on the eventual disposal if conditions are met, and can claim loss relief if the investment fails. The reliefs apply to the investor, not the company, but the company must qualify and m...
