Your CIS returns filed on time, every single month
CIS return service from Ben Kennell means your monthly deductions are recorded, verified and filed with HMRC by the 19th, without you having to touch it.
Whether you’re a subcontractor chasing deductions or a contractor managing payments to your subbies, I handle the paperwork so you can stay on site. Fixed monthly pricing starts from £25.
Is your CIS admin costing you more than it should?
Four questions. Takes 90 seconds. See exactly where your CIS filing stands.
How are you currently handling your CIS returns each month?
Do you know when your CIS return is due each month?
Are you confident the CIS deductions on your statements are being reported correctly?
How much of your own time do you spend on CIS admin each month?
Your CIS admin is overdue and carrying real financial risk
Penalties for late CIS returns start the day after the 19th of each month, and they compound quickly. If returns are missing or deductions are unrecorded, you could also be sitting on a tax reclaim you haven’t made. A short call with me costs nothing and can stop any further penalties from building up.
You’re managing CIS, but it’s taking more from you than it should
Filing your own returns and cross-checking contractor statements is time you’re spending away from paid work. There’s also a real risk that errors in your deduction records go unnoticed until they cause a cash flow problem. Handing this over frees that time and gives you someone to call if something looks off.
Your CIS is in good shape, but there may still be gaps worth checking
If you’re already on top of your filing, the main thing worth reviewing is whether every deduction is being captured and reconciled correctly in your records. From April 2026, HMRC has also introduced new nil-return requirements that affect contractors. It’s worth a quick check to make sure nothing has changed in how your returns need to be filed.
What I handle for you each month
No tools to learn, no portals to log into. You send me what you have and I take it from there.
CIS Monthly Return Filing
I prepare and submit your CIS return directly to HMRC each month, before the 19th deadline. If you’re a contractor with no subcontractor payments in a given month, I also file the required nil return so you’re not hit with an avoidable penalty.
Done for youCIS Deduction Verification and Reconciliation
Contractor errors in CIS deductions are more common than most subcontractors realise, and a wrong figure on your statement can cause a cash flow problem that takes months to sort out. I cross-check your statements against your Xero records so any discrepancies are caught early.
Error checkingCIS Bookkeeping on Xero
Your CIS deductions, payments to subbies and tax positions are kept up to date in Xero throughout the year, not just at month end. That means your records are clean when it comes to self assessment or year-end accounts, with no last-minute scramble.
Ongoing recordsWhy clients hand this over to me rather than carry on themselves
CIS filing is repetitive, deadline-driven and unforgiving when it goes wrong. Here is what changes when you stop doing it yourself.
You deal directly with me, not a team of strangers
I run this practice alone. When you email or call, it’s me who picks up, and I already know your file. There are no handoffs to junior staff and no explaining your situation from scratch every time.
Fixed pricing means no surprise bills
CIS work is priced at a fixed monthly rate from £25, so you know exactly what you’re paying before the month starts. There are no hourly rates, no add-on charges for filing and no bill shock at year end.
Your records are MTD-ready and HMRC-compliant from day one
Everything is managed through Xero, which is fully Making Tax Digital compliant. Your CIS figures sit inside the same records used for your self assessment or company accounts, so there’s no double-handling of data.
What clients say
How it works from your first call
There is no lengthy onboarding or weeks of back and forth. Most clients are set up and filing within a few days.
Book a free call
We spend 20 to 30 minutes on the phone going through where you are with your CIS right now. If you’re behind, we talk through what needs doing first and I’ll be straight with you about timelines and cost.
Share your CIS statements
You send me the CIS deduction statements from your contractors and any records you already have. I’ll tell you exactly what I need in plain terms, and you won’t need to pre-sort or format anything.
I set up your records and file the return
I build your CIS records in Xero, reconcile your deductions against what’s been reported and submit your return to HMRC. If anything looks wrong on a contractor’s statement, I flag it to you before filing.
Monthly filing handled from here
Each month I prepare and submit your return before the 19th deadline. You don’t need to remind me or chase. If I need anything from you I’ll ask, and I’ll confirm when it’s done.
