CIS admin piling up while you are on site?
Monthly CIS returns have a firm deadline. Miss one and HMRC issues a penalty; miss several and the fines compound quickly. Subcontractor verification is easy to overlook, and CIS deductions suffered by your company often go unreclaimed simply because no one has set it up correctly. Most contractors know there is money sitting there — they just never get around to sorting it.
- Monthly CIS returns missed or filed late, attracting HMRC penalties
- Subcontractors paid without being verified, creating compliance risk
- CIS deductions suffered never offset against your corporation tax bill
What sorted looks like
CIS returns filed on time every month, subcontractors verified before a payment goes out, and your deductions reclaimed correctly at year end. The compliance side stops being something you think about.
- Monthly returns filed before the 19th — penalties stopped before they start
- Every subcontractor verified with HMRC before their first payment
- CIS deductions offset against corporation tax — money back where it belongs
- Fixed monthly fee so there are no billing surprises at year end

Everything the CIS service covers
One fixed fee covers the full monthly cycle — returns, verification, deduction tracking, and year-end reclaim — so nothing falls between the gaps.
Monthly CIS Return Filing
Your monthly return is prepared and submitted to HMRC by the 19th each month. Deductions are recorded against each subcontractor so the figures are accurate and there is a clear audit trail if HMRC ever asks.
Included as standardSubcontractor Verification
Every subcontractor is verified with HMRC before you make a payment, and the correct deduction rate is applied — 20%, 30%, or gross status. Getting this wrong creates a liability for the contractor, not the subcontractor.
Included as standardCIS Deduction Reclaim
If your company has had CIS deducted from payments received, those amounts are offset against your corporation tax liability at year end. Many contractors pay more than they need to simply because this step is never done properly.
Included as standardClients across Hampshire — consistent results
Over 100 clients, a 99% retention rate, and a 5.0 Google rating. The variety of businesses is wide; the approach is the same for all of them.

What makes this firm worth calling
There are plenty of accountants who will file your returns. Fewer who will make sure the deductions are right, the verification is done, and the reclaim is picked up before year end.
CIS handled from start to finish
Verification, monthly returns, deduction tracking, and year-end reclaim are all covered under one fixed fee. Nothing gets left to the contractor to chase. The compliance cycle runs as it should, month after month.
21 years of practical experience
Supreme Consulting has been working with small businesses and contractors since 2005. CIS rules change, deadlines are firm, and the penalties for getting verification wrong sit with the contractor. Experience with this matters.
Fixed fee, no billing surprises
You will know the cost before you sign up. There are no hourly rates to worry about and no additional charges for a question asked mid-month. The fee is fixed and the scope is clear from day one.
Up and running in four steps
Most contractors are set up within a week. The transition is handled at this end — you do not need to prepare anything before calling.
A brief discovery call
A short, no-obligation conversation covering your current setup — how many subcontractors you work with, whether returns are up to date, and what you need going forward. No paperwork required beforehand.
A clear, fixed proposal
You receive a written proposal with the scope, the monthly fee, and what is included. No vague hourly estimates — you know the cost before agreeing to anything.
We take over the compliance
Existing records are reviewed, any catch-up is handled, and the monthly filing cycle starts from there. If books need tidying before we can begin, that is scoped and priced separately — no surprises.
CIS runs without your input
Subcontractors are verified, returns go out on time, and deductions are tracked all year. By the time your corporation tax return is prepared, the CIS reclaim is already in the figures. Which is, frankly, the way it should be.

Answers to what most contractors ask first
Do you handle both the contractor and subcontractor sides of CIS?
Yes. If you are a contractor deducting from subcontractors, the monthly return and verification process is handled in full. If you are a subcontractor with CIS deducted from your payments, those amounts are tracked and reclaimed against your corporation tax at year end. A number of construction businesses operate on both sides of the scheme at once — that is handled without complication.
What does CIS compliance cost and what exactly is included?
Pricing is fixed and based on the number of subcontractors and the complexity of your setup. A clear quote is provided before you commit to anything. The fee covers subcontractor verification, monthly return preparation and submission, deduction record-keeping, and coordination with your year-end accounts for the reclaim. There are no add-on charges for questions asked between filings.
My CIS returns are behind — can you sort that out?
Yes. Late returns are common, particularly for contractors who have been managing it themselves. The first step is a review of what has been filed and what is outstanding. Any catch-up work is scoped and priced transparently before it begins. HMRC penalties for late CIS returns are fixed amounts, so knowing the exposure early tends to make it more manageable.
Is there a long-term contract?
No. There is no minimum term and no exit penalty. If you decide to leave, your records are provided in full. The business retains nothing that belongs to you. Most clients stay because the service works, not because leaving is difficult.
What happens if a subcontractor’s CIS status changes mid-year?
Subcontractor gross payment status can be revoked or amended by HMRC. When that happens, the deduction rate changes immediately and the monthly return has to reflect it correctly. Keeping subcontractor verification records current is part of the ongoing service — you will not be applying the wrong rate because a status changed and nobody noticed.
Can CIS deductions my company has suffered actually reduce what I owe in corporation tax?
They can, and this is the part that gets missed most often. If your company has had CIS deducted from payments it has received, those amounts are offset against your corporation tax liability — or refunded if the deductions exceed the tax owed. It requires correct record-keeping throughout the year and accurate reporting on your CT600. When it is set up properly, the reclaim is straightforward.
