CIS payroll software that gets the deductions right
CIS payroll software calculates the tax that contractors must deduct from subcontractor payments under HMRC's Construction Industry Scheme, and produces the statements and records the scheme requires. Valegrid Flow calculates CIS deductions automatically from approved timesheets — 20% for verified workers, 30% for unverified, or no deduction for gross status — applied to the labour element only, never VAT or materials, and rounded down per HMRC convention. Every finalised payroll run produces CIS statements and a payment CSV export.
CIS deductions calculated automatically, at the right rate
Valegrid Flow stores each worker's UTR and verification status, then applies the correct rate on every payroll run — 20% for verified workers, 30% for unverified, or no deduction for gross status. The deduction only ever touches the labour element, never VAT or materials, and figures are rounded down per HMRC convention. No rate look-ups, no manual arithmetic, no wrong-rate surprises.
Payroll runs built on locked timesheets
Pay is calculated straight from approved timesheets, so every run matches the hours and days actually signed off. Each run is calculated, reviewed and finalised in order, and the timesheets behind it are locked — the numbers can't shift after you've checked them. Day-rate and hourly workers are both supported.
CIS statements and payment exports with every run
Every finalised payroll run produces CIS statements for your workers and a payment CSV export. Paying out and keeping the paperwork the scheme expects becomes one job, not two.
CIS suffered and CIS made, tracked in one place
What contractors deduct from your invoices is CIS suffered; what you withhold from your own subcontractors is CIS made. Valegrid Flow tracks both, with figures broken down by monthly CIS period, so you can see your position for each period at a glance.
How it works
- Step 1
Approve timesheets
Hours and day rates go through timesheet approval first. Approved timesheets are the single source for the payroll run.
- Step 2
Calculate and review the run
Valegrid Flow applies each worker's CIS rate — 20%, 30% or gross — to the labour element only, rounded down per HMRC convention. You review every figure before anything is finalised.
- Step 3
Finalise and export
Finalising locks the timesheets behind the run and produces CIS statements plus a payment CSV export, ready to pay out and file away.
Frequently asked questions
- What CIS deduction rates does Valegrid Flow apply?
- Valegrid Flow applies HMRC's standard rates per worker: 20% for verified subcontractors, 30% for unverified, and no deduction for workers with gross payment status. Each worker's UTR and verification status is stored, so the correct rate is applied automatically on every payroll run.
- Are CIS deductions applied to materials or VAT?
- No. Under the Construction Industry Scheme, deductions apply to the labour element of a payment only. Valegrid Flow calculates CIS on labour alone — never on VAT or materials — and rounds the deduction down in line with HMRC convention.
- What is the difference between CIS suffered and CIS made?
- CIS suffered is the tax contractors deduct from your invoices before paying you; CIS made is the tax you withhold from your own subcontractors' payments. Valegrid Flow tracks both, with monthly CIS-period figures, so both sides of the scheme sit in one place.
- Does Valegrid Flow handle both day-rate and hourly workers?
- Yes. Payroll runs are calculated from approved timesheets for day-rate and hourly workers alike, and CIS deductions are applied the same way for each — at 20%, 30% or gross depending on the worker's verification status.
