CIS software that handles the deductions, statements and returns for you
The Construction Industry Scheme turns every subcontractor payment into a compliance task: verify the subbie, apply the right deduction, keep the statement, total it up for the monthly return. Get it wrong and it's a penalty; do it by hand and it eats a day a month.
CrewFlow runs CIS as part of how you already pay subcontractors, so the deductions, the statements and the monthly figures fall out of the work instead of being a separate chore.
- Deductions worked out automatically at 20%, 30% or gross
- Verification status tracked against each subcontractor
- Payment & deduction statements produced as PDFs
- Monthly CIS return totals ready to file
CIS is a penalty waiting for the month you're too busy
Miss a verification, apply the wrong rate, forget a statement or file the monthly return late, and HMRC's penalties start at £100 and climb. The scheme doesn't care that you were on site all month. CrewFlow keeps the deductions right and the paperwork ready as you pay subcontractors, so the monthly return is a review, not a scramble.
The right deduction on every subcontractor payment
Set each subcontractor's status, gross, net at 20%, or unregistered at 30%, and CrewFlow applies it automatically every time you record a payment. The deduction is taken off the labour element, materials are left out of the calculation, and the figure is logged against both the subcontractor and the job it belongs to.
- 20%, 30% or gross applied per subcontractor
- Deduction calculated on labour, not materials
- Every deduction tied to the subcontractor and the job
Verification and statements, kept as you go
Record each subcontractor's HMRC verification number and status so you always know who's verified and at what rate before you pay them. Every payment produces a payment & deduction statement as a clean PDF you can send the subcontractor, the proof they need of the tax you've withheld on their behalf.
The monthly return, totalled and ready to file
At month end CrewFlow totals every subcontractor, every payment and every deduction into the figures your CIS300 monthly return needs. CrewFlow produces the numbers and the statements; you or your accountant submit the return to HMRC, so filing is a five-minute check rather than a reconciliation from a shoebox of invoices.
20%, 30% or gross applied automatically per subcontractor.
Payment & deduction statement PDFs produced as you pay.
CIS300 totals ready to file, not reconstructed under pressure.
Common questions
Does CrewFlow calculate CIS deductions automatically?
Yes. Set each subcontractor's status, gross, 20% net or 30% unregistered, and CrewFlow applies the right deduction to the labour element of every payment and logs it against the subcontractor and the job.
Does CrewFlow file the CIS300 return to HMRC?
No, and like our tax figures that's deliberate. CrewFlow produces the monthly CIS300 totals and the subcontractor statements; you or your accountant submit the return to HMRC. It removes the admin, not your control over filing.
Can I produce subcontractor payment and deduction statements?
Yes. Every subcontractor payment produces a payment & deduction statement as a PDF you can send the subcontractor as proof of the tax deducted.
Does it track subcontractor verification?
Yes. You record each subcontractor's HMRC verification number and status, so you always know who's verified and at what rate before you pay them.
