CIS admin piling up faster than the invoices?
Monthly CIS returns look straightforward until they are not. Verifying each subcontractor, applying the right deduction rate, issuing statements, and keeping records that will hold up to an HMRC query — it adds up. Most contractors running their own CIS are one missed deadline or one incorrect deduction away from a penalty they did not see coming.
- Monthly CIS300 submissions filed late or with incorrect deduction rates
- Subcontractor deductions not being reclaimed through payroll or self assessment
- No paper trail of verification checks, deduction statements, or HMRC correspondence
What a handled CIS scheme looks like
When the scheme is run properly, the 19th is not something you think about. Returns go in, subcontractors receive their statements, and deductions are tracked and reclaimed where they should be.
- CIS300 filed correctly and on time, every month, without chasing
- CIS deductions offset against your PAYE or reclaimed through self assessment
- Verification records, deduction certificates, and HMRC correspondence kept in order
- Transparent fixed quote based on your number of subcontractors — no surprises

Prads has been exemplary in assisting with all the paperwork and guiding me to access the relevant codes from Companies House to facilitate submission of both Accounts and HMRC tax information.

What the CIS service covers
A fully managed CIS service for contractors and subcontractors — monthly filings, verification, deduction tracking, and recovery of overpaid tax.
Monthly CIS300 Returns Filed
Your monthly contractor return is prepared and submitted to HMRC before the 19th deadline, every month. We verify each subcontractor, apply the correct deduction rate — 0%, 20%, or 30% — and maintain the records HMRC expects to see. You do not have to log in to HMRC, chase verification references, or remember the deadline.
Core complianceDeduction Statements for Subcontractors
Every subcontractor on your books needs a monthly deduction statement showing what was paid and what was withheld. We issue these each month so your subcontractors have what they need to reclaim through their own self assessment or payroll. Keeps your relationships clean and your obligations met.
Included as standardCIS Deduction Recovery
If you are a subcontractor, CIS deductions taken at source reduce your tax liability — but only if they are correctly offset. We track your deductions and either set them against your PAYE bill or claim a refund through self assessment, so you are not leaving money with HMRC that belongs to you.
For subcontractorsConsistently good across different businesses
From sole trader builders to limited company contractors, the same outcome comes back: clear communication, reliable delivery, and fewer things to worry about.
Accounts Together Quickly, Weight Off Mind
“Prads was very professional and efficient with good communication. My accounts were put together very quickly, a huge weight off my mind. Definitely recommend their services.”
Went Above and Beyond, Would Recommend 100%
“Prads at Wings online filings went above and beyond to help us out in a timely and professional manner, flexible online meetings, extra work to fix my mistakes. Would recommend 100%”
Affordable, Reliable, Quick and Clear Communication
“Incredible service and really affordable support for small businesses. Super quick and clear communication, and very reliable. Really loved working with them, highly recommend!”
What makes the difference month to month
There are plenty of accountants who can file a CIS return. Fewer who stay on top of it without prompting, explain what the numbers mean, and price it so it is never a question worth asking.
The 19th Is Not Your Problem
Monthly CIS deadlines have a way of arriving faster than expected, especially when you are on site. We manage the return, the verification checks, and the submission without waiting to be chased. You find out when it is done, not when it is due.
Deductions Tracked and Recovered
Overpaid CIS tax is common, particularly for subcontractors who do not realise deductions can be offset against PAYE or reclaimed at year end. We track what has been withheld and make sure it comes back to you rather than sitting with HMRC indefinitely.
Construction Work Explained Plainly
Gross payment status, deemed contractors, the reverse charge on VAT — the construction scheme has more moving parts than most sectors. We explain what applies to your situation in plain terms, without assuming you have read the HMRC guidance in full.
Up and running in four steps
Most construction businesses are filing their first return with us within a week of getting in touch. Here is what that looks like.
Tell us about your scheme
Fill in the short quote form or call us directly. We need to know whether you are a contractor, a subcontractor, or both, and roughly how many subcontractors you pay each month. That is enough to give you a fixed monthly quote.
We take the scheme over
You share access to your HMRC CIS portal or give us the subcontractor details we need. We verify everyone, confirm the correct deduction rates, and pick up the monthly filing from there. Any backlog or missed returns is sorted before we move forward.
Returns filed, statements issued
Each month, before the 19th, your CIS300 return goes in. Deduction statements go out to your subcontractors. You receive a confirmation. You do not need to do anything else unless something changes on your scheme.
The 19th stops mattering
After a couple of months, most clients stop thinking about CIS deadlines altogether — which is exactly how it should be. Your records are clean, your subcontractors have their statements, and any overpaid tax is being tracked for recovery. The scheme is simply handled.
“Professional, efficient, confidence that everything is taken care of.”
CIS questions worth answering properly
Do you handle both the contractor side and the subcontractor side of CIS?
Yes. If you are a contractor, we file your monthly CIS300 return, verify subcontractors, apply the correct deduction rate, and issue deduction statements. If you are a subcontractor, we track the CIS tax deducted at source and ensure it is either offset against your PAYE liability or reclaimed through your self assessment return. If you operate as both — which is common in construction — we manage the scheme end to end.
What does CIS return filing cost?
CIS is priced on a quote basis because the monthly effort depends on how many subcontractors you pay and how your records are kept. Most contractors with a handful of subcontractors find the monthly fee is straightforward and predictable. We provide a fixed quote before anything starts, and if you find a lower price elsewhere we will match it.
I have missed several CIS returns. Can you help sort the backlog?
Yes, and it is more common than you might expect. We will identify which returns are outstanding, calculate the correct deductions for each period, and submit them to HMRC. Late filing penalties are automatic under CIS, so the sooner the backlog is cleared, the better. We will be straightforward with you about what is owed before we begin.
Is there a long-term contract to sign?
No. CIS is an ongoing monthly obligation, so most clients stay because the service is working — not because they are tied in. If you want to stop, you give us notice and we hand everything over in good order. There is no penalty and no paperwork to fight through.
What is gross payment status and should I apply for it?
Gross payment status means HMRC pays you in full without deducting CIS tax at source — useful for cash flow if you are a subcontractor. To qualify, your business needs to pass HMRC’s compliance, turnover, and business tests. We can review whether you are likely to qualify and handle the application if it makes sense for your situation.
How does the CIS reverse charge affect my VAT returns?
The domestic reverse charge applies to most construction supplies where both contractor and subcontractor are VAT-registered. Instead of the subcontractor charging VAT, the contractor accounts for it on their own VAT return. It affects your cash flow and the figures on your VAT return. We manage both CIS and VAT together for clients where this applies, so the two schemes are aligned and nothing falls through the gap.
