We check your CIS statements, claim the van, tools and mileage, and file your return so any tax that was over-deducted comes back to you. A fixed monthly fee, never a cut of your refund.
Joiners, sparks, plumbers, plasterers, labourers and every other trade working under CIS.
Send us your payment and deduction statements as they arrive. We check the sums, chase missing ones and make sure nothing has been taken off materials.
Before we file, we match your deductions to what your contractors reported to HMRC, so a mismatch doesn’t hold up your refund.
Van, fuel or mileage, tools, protective gear, phone, training and cards, insurance and travel to site. All of it cuts the tax you actually owe.
We file as soon as the tax year closes on 5 April, so the money comes back to you sooner.
Not filed for a while? Overpaid tax from earlier years can often still be claimed. We’ll look back and tell you what’s there.
Ready to be paid without deductions? We help you apply. VAT registered? We handle the construction reverse charge.
Registered subcontractors have 20% taken off the labour part of each payment. Not registered with HMRC? It’s 30%. Those deductions are a payment towards your tax bill, not the bill itself.
A joiner invoices £3,000: £1,000 of materials and £2,000 of labour. The contractor should deduct 20% of £2,000, which is £400, not £600.

How CIS really works, and where the money goes missing.
CIS takes 20% from your first pound of labour. It knows nothing about your personal allowance or your expenses. Your real tax bill is worked out on profit, after both, so the deductions often add up to more than you owe.
Contractors must give you a payment and deduction statement by the 19th of each month for the month before. Keep every one. A missing statement, or tax taken off materials, is far easier to fix now than at the end of the year.
Your van (as mileage, or running costs plus capital allowances), fuel, tools and equipment, protective clothing and boots, phone, public liability insurance, CSCS cards and training, and travel to temporary sites. Everyday clothes, and the commute to a permanent base, don’t count.
Get paid in full with nothing deducted. You’ll need construction turnover of at least £30,000 a year, not counting VAT and materials, a business bank account, and a record of filing and paying on time. The catch: you pay your own tax in January, so you need to set money aside.
If at least 80% of your tax is already covered by CIS deductions, HMRC doesn’t ask for payments in advance. That changes if you move to gross payment, which is when budgeting really matters.
If you’re VAT registered and work for a VAT-registered contractor, you usually don’t charge them VAT on CIS work. They account for it instead. Your invoices need the right wording, and getting it wrong causes headaches for both of you.
General guidance for the 2026/27 tax year, not advice for your situation. Ask us before acting on it.
We only work with sole traders, CIS subcontractors and landlords. Monthly statements, refunds and gross status are routine to us.
Refund agencies often take a percentage of what comes back. We charge one fixed monthly fee, agreed in writing, so the refund is all yours.
The person doing your accounts answers your emails, within one business day. No call centre.
Snap statements and receipts on your phone and upload them to your portal. No more carrier bag in the van.
We can file as soon as the tax year ends on 5 April. HMRC usually pays within a few weeks, though they sometimes check CIS claims first, which takes longer. Matching your statements to HMRC’s records before we file helps avoid that.
No. You pay one fixed monthly fee, agreed before we start. Whatever comes back is yours.
That’s common. We ask your contractors for copies and check HMRC’s record of what was reported.
Yes. Register with HMRC as a CIS subcontractor and future deductions drop to 20%. We can sort that for you. The extra already taken still counts towards your tax bill.
Maybe not. If they decide when, where and how you work, supply the tools and you can’t send someone in your place, you could be an employee in all but name. That affects your rights and your tax, so it’s worth a chat.
Yes. Once you sign up we contact them for the handover, get authorised with HMRC and pick up where they left off. You don’t need to have the awkward conversation.
Tell us a little about you and we’ll come back within one business day with a fixed monthly fee.
