The CIS Suffered Reclaim Process Explained

A CIS deduction can feel like tax paid twice when money has already been held back from your invoice and you still have payroll and other business costs to cover. For limited companies working in construction, understanding the CIS suffered reclaim process is key to recovering cash that belongs to the business without creating problems with HMRC.

The rules are not difficult once the order is clear. The trouble usually starts when records are missing, deductions are claimed too early, or a company asks for a repayment before using the tax correctly against its PAYE liabilities. Getting the process right protects cash flow and keeps your company’s compliance position clean.

What does CIS suffered mean?

CIS suffered is the tax deducted from payments made to your limited company by a contractor. For example, if your company completes subcontract work and the contractor deducts 20% under the Construction Industry Scheme, that deduction is CIS tax your company has suffered.

It is not an extra cost of doing business and it is not normally lost. It is tax already paid to HMRC on your company’s behalf. The company can usually use it to reduce the PAYE, National Insurance and other employment taxes it owes through its payroll scheme. If there is more CIS suffered than can be used in this way, the remaining balance may be reclaimed from HMRC.

This point matters because the route is different for a sole trader. A self-employed subcontractor normally reports CIS deductions through their Self Assessment tax return. A limited company generally claims through its PAYE scheme and, where appropriate, an HMRC repayment claim.

The CIS suffered reclaim process for limited companies

The process begins with evidence. Before claiming any deduction, make sure the company has the paperwork to support it. That normally means payment and deduction statements from each contractor, showing the gross amount, materials where relevant, the deduction made, and the contractor’s details.

Your company should also ensure that the income relating to those deductions has been properly recorded in its accounts. HMRC may query a claim where the CIS deductions do not match the company’s turnover, invoices or contractor records. A payment statement is valuable, but it needs to sit alongside a clear bookkeeping trail.

Step one: Record deductions accurately

Each monthly CIS statement should be checked and recorded promptly. Do not rely on a year-end bundle of paperwork from the van, kitchen drawer or site office. Missing one statement can mean leaving money unclaimed, while entering the same deduction twice can lead to an overclaim and an HMRC enquiry.

Check that the company name and unique tax reference details are correct. If the contractor has paid and deducted tax under an old trading name or against the wrong entity, the issue needs correcting before a claim is made. This is particularly important where a sole trade has later incorporated, as deductions belonging to the individual cannot simply be moved into the limited company.

Step two: Set CIS suffered against payroll liabilities

A company usually offsets CIS suffered through its monthly or quarterly Employer Payment Summary, commonly called an EPS. The claim reduces the amounts due to HMRC under PAYE. Depending on the company’s payroll position, this can include PAYE tax, employee and employer National Insurance contributions, and other relevant amounts reported through the PAYE scheme.

The claim should only be for deductions the company has actually suffered and can evidence. It should also be made through the correct PAYE reference. If your payroll is run monthly, keeping the CIS records up to date allows the available credit to reduce payments as the year progresses, rather than waiting until cash is tight.

There is a practical trade-off here. Claiming monthly can improve cash flow, but it requires disciplined records and payroll reporting. Some small companies prefer their accountant to review the deductions first, particularly if they work for several contractors or have irregular payment patterns.

Step three: Carry forward any unused credit

If CIS suffered is greater than the company’s PAYE liabilities, the excess is carried forward. It remains available to offset against future payroll liabilities in the same tax year.

This often happens when a construction company has only one director on a modest salary, but significant CIS deductions taken from its invoices. The company may have plenty of CIS credit and very little PAYE to pay each month. Carrying the credit forward is normal. It does not mean there is an error or that the money has disappeared.

Step four: Apply for repayment where appropriate

At the end of the tax year, a limited company may be able to claim back any CIS suffered that it could not set against PAYE liabilities. HMRC will review the claim and may ask for supporting information before issuing a repayment.

A repayment claim needs to agree with the company’s payroll records, its CIS deduction statements, its accounts and the income shown in its Corporation Tax return. HMRC is likely to take a closer look if the figures do not line up, if deductions are high compared with declared turnover, or if the company has outstanding tax debts.

A refund can sometimes be set against other amounts owed to HMRC rather than paid directly to the company. That is not necessarily wrong, but it can affect cash-flow expectations, so it is worth checking the company’s wider tax position before relying on a repayment for a planned expense.

Common reasons CIS reclaim claims are delayed

Most delays are preventable. The biggest issue is poor evidence. Contractors are required to provide deduction statements, but subcontractors should still chase them where they are missing. A bank payment alone may show that money arrived, but it does not always prove the gross payment and CIS tax deducted.

Another common problem is claiming deductions that relate to materials rather than labour, or using a figure from an invoice instead of the amount actually deducted. CIS is calculated under specific rules, and materials are treated differently. The statement from the contractor is the starting point, not an estimate.

Timing can also cause trouble. A company cannot claim tax merely because it expects a contractor to deduct it. The deduction must have been made and supported by the relevant statement. Equally, a late contractor statement should not be ignored just because the payroll month has passed. The records may need correcting so the company receives the credit it is due.

Finally, make sure that your PAYE reporting is up to date. HMRC may hold up a repayment where Full Payment Submissions, Employer Payment Summaries, Corporation Tax filings or other returns are overdue. A clean compliance record makes the whole process easier to manage.

Keep a simple monthly CIS file

For most construction companies, a straightforward monthly system is enough. Keep copies of invoices issued, contractor deduction statements, payment records and payroll reports together. Reconcile the gross income and CIS deducted against the bookkeeping records before payroll is finalised.

It is also sensible to keep a running total of CIS suffered, CIS used against PAYE, and any balance carried forward. This gives you a realistic view of what HMRC may owe the company and prevents the same credit being claimed twice.

If you use subcontractors yourself, keep that side of the CIS scheme separate from your company’s own suffered deductions. Paying subcontractors, filing monthly CIS returns and recovering CIS deducted from your company’s income are connected by the scheme, but they are not the same job. Mixing the records is an easy way to create confusion.

When professional support is worth having

The CIS rules can become more involved where a business has changed structure, has multiple PAYE schemes, receives payments through agencies, or has deductions recorded incorrectly by contractors. It can also take time to resolve a claim where HMRC asks for evidence going back several months.

Short And Sons Accountants helps construction clients keep CIS, payroll and company records aligned, so claims are based on figures that can be supported from the outset. That means less time spent chasing paperwork and a clearer picture of the cash available to the business.

Treat CIS statements as part of your monthly financial paperwork, not as something to deal with after the tax year ends. A few minutes of checking when each payment arrives can make the difference between a straightforward reclaim and a long wait for money your company has already earned.
