CIS Returns and Refunds for Roofers

Written and reviewed by the Roofer Accountants editorial team. Last reviewed 29 July 2026.

This is the CIS engagement, both sides of it. For a subcontractor roofer we claim the refund you are owed through your return. For a roofer who pays others, we run the monthly CIS returns and statements. Where the guides explain how CIS works, this is us doing it and owning the deadlines.

Fixed fee, agreed before we begin, for whichever side, or both, applies to you.

What We Handle

On the subcontractor side: totalling the CIS deducted from your payment and deduction statements, setting your income against your expenses and allowance, and claiming the overpaid difference as a refund through Self Assessment.

On the contractor side: verifying subcontractors with HMRC, working out the right deduction on labour, filing the monthly return by the 19th, and issuing each subcontractor their statement. Nil returns where a month has no payments, so you do not pick up a penalty.

Where CIS Goes Wrong

For subcontractors, the usual failure is an incomplete refund: expenses missed, statements lost, the claim rushed. For contractors, it is a late or missed monthly return, which brings an automatic penalty, or deducting the wrong rate because a subcontractor was not verified.

We fix both by owning the CIS cycle: complete refund claims on one side, on-time verified returns on the other, so nothing is left on the table and no penalty is picked up.

How It Runs

Send us your CIS statements and records, or your subcontractor details if you are the contractor. We do the work, show you the figures, the refund or the deductions, and file once you approve. Identity checks first. The contractor side runs monthly; the refund side runs at year end or as soon as you are ready to claim a past year.

It sits alongside the rest of your accounts and tax, or stands alone if CIS is all you need handled.

What It Costs

A fixed fee agreed before work starts. A single-year subcontractor refund return is at the lower end; ongoing monthly contractor returns for a firm with several subcontractors costs more, priced clearly so you can choose the level.

To get a price, tell us which side of CIS you are on and we will come back with a fixed quote.

Common questions

Can you claim my CIS refund?

Yes. We total the CIS deducted from your statements, set your income against your expenses and allowance to find your real tax, and claim the overpaid difference as a refund through your Self Assessment return.

Can you file my monthly CIS returns?

Yes. If you pay subcontractors we verify them, work out the deduction on their labour, file the monthly return by the 19th and issue their statements, including nil returns so you do not pick up a penalty.

Do you handle both subcontractor and contractor CIS?

Yes, and many roofing firms are both. We claim the refund on the subcontractor side and run the monthly returns on the contractor side, so the whole of your CIS is handled together.

What does it cost?

A fixed fee agreed up front, scaled to whether it is a one-off refund or ongoing monthly returns and how many subcontractors are involved. Tell us your situation and we will price it.

Get a fixed fee before any work starts

Tell us whether you are a sole-trader roofer or a roofing firm, and what is outstanding: your CIS refund, the returns, the VAT, or a deadline with HMRC. We come back with a fixed price and the date it has to be finished by.
