CIS statement generator

CIS statement generator

A CIS statement generator turns a list of what you paid your subcontractors this tax month into the Payment and Deduction Statements HMRC requires you to give each one, plus the totals for your CIS300 return. Ours runs entirely in your browser: upload a CSV, get a free preview of a couple of statements, and pay a one-off amount to unlock the full batch as a ZIP. We don't file anything to HMRC on your behalf, we produce the documents you send and the totals you file.

Open the tool
Correct by construction
The deduction is calculated on gross minus materials and other excludable costs, at the rate your subcontractor's CIS status determines, grouped by the 6th-to-5th tax month HMRC actually uses.
One upload, every subcontractor
List every subcontractor you paid this tax month once. You get one statement per subcontractor per tax month back, consolidated if they were paid more than once.
Your data stays on your device
The CSV is parsed and the statements are generated in your browser. We never see or store your payment data.

Frequently asked questions

What exactly does this generate?

A CIS Payment and Deduction Statement per subcontractor per tax month, and a CIS300 summary of the totals across all of them. Both come from the same calculation, so they always agree.

Does this file my CIS300 return with HMRC?

No. We calculate the totals you need for your return. Filing it, whether through your accounting software, your accountant, or HMRC's own service, is still on you.

What CSV do I need?

Subcontractor name, UTR, CIS status (registered, unregistered or gross), payment date, gross amount and materials amount, one row per payment. We handle the rest, including grouping multiple payments to the same subcontractor within a tax month.

How much does it cost?

Free to preview a couple of statements from your own data. Unlocking the full batch as a ZIP is a one-off payment per upload, roughly £9 to £19 depending on batch size, no subscription.

What's the deadline for giving a subcontractor their statement?

Within 14 days of the end of the tax month the payment falls in. The tax month runs 6th to 5th, and your CIS300 return covering the same period is due by the 19th.

Free to preview, one-off payment to unlock the full batch. Your payment data never leaves your device.
