CIS Returns for UK Contractors
Your CIS returns filed correctly, every month.
If you engage subcontractors on construction work, you are legally required to verify them with HMRC, deduct the right amount, and file a monthly CIS300 return. Miss one and the penalties start immediately. We handle the whole process for you: a qualified accountant, transparent pricing, and replies the same day you ask.
- Monthly CIS300 returns filed on time, every time
- Subcontractor verification handled before the first payment goes out
- Deduction statements issued to your subbies each month
- CIS deductions reclaimed through your tax return, so you keep what you are owed
No long-term contract. If things are not working after three months, you leave with your records in order and nothing owed.

Sound familiar?
CIS admin piling up on top of the build programme?
Construction contractors are running sites, managing labour, and chasing materials. The monthly CIS return deadline does not care about any of that. Miss the 19th of the month and HMRC issues a penalty without warning. Get the deduction rate wrong on a subcontractor and you can end up liable for the difference. Most contractors either muddle through themselves or find out too late that something was filed incorrectly.
- Monthly CIS300 returns missed or filed late, triggering automatic HMRC penalties
- Wrong deduction rates applied because subcontractor verification was skipped
- Subcontractors chasing for their deduction statements, which you have not got round to issuing
What having it handled looks like
We take the CIS administration off your plate completely. Subcontractors verified before their first payment, returns filed well before the 19th, and deduction statements issued promptly each month. No chasing, no last-minute scrambles.
- CIS300 returns filed before the deadline, with no penalty risk left to chance
- Every subcontractor verified with HMRC before a payment is made, at the correct rate
- Deduction statements prepared and sent to your subbies each month, automatically
- CIS deductions reclaimed through your company or personal tax return, so nothing overpaid sits with HMRC

Everything your CIS obligations require
CIS is quote-based because the volume varies: the number of subcontractors and whether you need catch-up work both affect the fee. We will give you a clear figure before any work starts.
Monthly CIS Returns Filed
We prepare and submit your CIS300 return to HMRC each month, covering all payments made to subcontractors during the period. The filing happens before the 19th deadline, and you receive confirmation once it is done. No chasing required on your end.
Filed by the 19th each monthSubcontractor Verification and Deduction Statements
Before any payment goes out, we verify each subcontractor with HMRC to confirm the correct deduction rate (gross, standard, or higher). Once payments are made, we prepare and issue monthly deduction statements so your subbies have the paperwork they need for their own tax returns. This prevents disputes and keeps your records complete.
Included as standardCIS Deduction Reclaims
If you work as a subcontractor yourself, deductions taken from your payments by contractors can be reclaimed against your tax bill. We handle this through your Self Assessment or Corporation Tax return, making sure nothing overpaid sits with HMRC for longer than it needs to. For limited company subcontractors, we also handle the offset against PAYE and NIC liabilities where applicable.

What makes the difference for construction businesses
CIS compliance is time-sensitive and leaves little room for error. Here is why contractors choose to hand it to us.
Deadlines Treated as Non-Negotiable
The CIS300 return must reach HMRC by the 19th of the month following the payment period. We treat that as a hard line, not a rough target. Your return is prepared and filed early, with confirmation sent to you once it is through.
Verification Done Before Payment Goes Out
Paying a subcontractor before verifying them with HMRC can result in the wrong deduction rate being applied and HMRC holding you responsible for the shortfall. We handle verification as part of the onboarding for every new subcontractor, so the correct rate is applied from day one.
Plain English, Not Jargon
CIS involves a fair amount of HMRC terminology, deduction rates, gross status conditions, and offsetting rules. We explain what is relevant to your situation in plain terms, so you understand what is happening and why, without needing to read the HMRC guidance yourself.
Up and running in four straightforward steps
Most contractors are set up and have their first return filed within a few working days of getting in touch.
Request a Quote
Fill in the short form on this page or give us a call. Tell us how many subcontractors you typically pay each month and whether there is any catch-up needed. We will come back to you the same day with a clear, itemised quote.
We Gather What We Need
Once you are happy to go ahead, we ask for a short list of details: your PAYE reference, subcontractor information, and any previous returns if there are gaps to fill. We keep the information request to what we genuinely need, nothing more.
Verification and First Return
We verify your subcontractors with HMRC, confirm the correct deduction rates, and prepare the first CIS300 return for your review. You confirm the payment figures are correct and we submit. Deduction statements go out to your subbies the same day.
Ongoing, With No Chasing
From that point, we manage the monthly cycle. You send us the payment figures, we handle everything else. No missed deadlines, no last-minute pressure, and a clear record kept throughout the year so your end-of-year reclaim is straightforward.
“Professional, efficient, confidence that everything is taken care of.”
Things contractors usually want to know first
Do you handle CIS for both contractors and subcontractors, or just one side?
We work with both. For contractors, we manage the monthly CIS300 returns, subcontractor verification, and deduction statements. For subcontractors, we handle the reclaim of CIS deductions through your Self Assessment or Corporation Tax return. If you sit on both sides of a contract (common in construction), we handle both sets of obligations together.
What does CIS returns management cost, and what is included?
CIS is priced on a quote basis because the volume of subcontractors and the complexity of your set-up both affect the work involved. The quote covers monthly returns, verification of subcontractors, and deduction statements. We will give you a clear, written figure before any work begins, with no hidden extras added later.
What if we have missed returns or have not been filing CIS at all?
This is more common than people admit, and it is fixable. We can review what has been filed (or not filed), work out what is outstanding, and prepare catch-up returns where needed. HMRC does issue late filing penalties for CIS, but getting things in order promptly limits the exposure. We will be straightforward with you about what is owed and what the likely penalty position is before we start.
Is there a minimum contract length or lock-in period?
No. We do not tie clients in. Most contractors stay because the arrangement works, not because they have to. If you decide to move on, we hand over your records cleanly and promptly. There is no cancellation fee.
How does gross payment status work, and can you help us apply for it?
Gross payment status means HMRC pays the subcontractor in full, without any deduction, because they have met certain compliance tests (turnover, tax compliance record, and business type). If your business qualifies, applying for gross status can significantly improve your cash flow. We can assess whether you are likely to meet the criteria and handle the application to HMRC on your behalf.
Can CIS deductions offset our PAYE and NIC liability as a limited company subcontractor?
Yes, and this is often overlooked. If you operate through a limited company and have CIS deductions taken from your payments, those deductions can be offset against the PAYE and National Insurance Contributions your company owes to HMRC each month. This reduces or eliminates the cash outflow to HMRC on your payroll, rather than waiting until the year-end Corporation Tax return to reclaim. We manage this offset as part of your monthly payroll submission where it applies.
Get your CIS returns properly handled.
Send us the payment figures each month and we take care of everything else: verification, deduction statements, the CIS300 submission, and your end-of-year reclaim. Clear pricing agreed upfront.
