Civil engineering contracts run on large gangs of subcontracted labour paid monthly against measured or valued work, frequently across several concurrent contracts with their own valuation dates. That means a civils contractor's CIS run each month can span dozens of subcontractors and multiple materials and plant deductions per gang. This is the volume end of CIS, and it's where a spreadsheet upload earns its keep the most.

Whether it's 20 subcontractors or 200, the same upload produces one correct statement per subcontractor per tax month.
Where a gang is paid against more than one valuation in the same tax month, the payments are consolidated onto a single statement.
The CIS300 summary is generated from the exact same figures as the statements, so your return and your paperwork always agree.
No. We generate the CIS Payment and Deduction Statements and the CIS300 totals you need. You still send the statements to your subcontractors and file your return yourself, or hand the totals to your accountant.
Within 14 days of the end of the tax month the payment falls in. The CIS tax month runs 6th to 5th, not the calendar month, so a payment on 3 May belongs to the 6 April to 5 May tax month.
0% if the subcontractor is registered for gross payment, 20% if they're registered for net payment, 30% if they're not verified with HMRC. You tell us the status per subcontractor and we apply the right rate.
