Groundworks is one of the heaviest CIS trades: large gangs of subcontracted labour on drainage, footings and site clearance, often paid weekly but reconciled monthly, plus plant hire and materials that need to come off the taxable figure. A groundworks contractor can easily be issuing statements to 20 or 30 subcontractors a month. One upload replaces that stack of individual calculations.
Runs in your browser · your subcontractors’ data never reaches us
Whether you're paying 5 gangs or 50 subcontractors in a month, the upload and the output scale the same way: one row per payment, one statement per subcontractor.
Where plant hire or materials are billed alongside labour, keep them out of the gross labour figure so the deduction is calculated on the right base.
A gang paid twice in one tax month gets one consolidated statement; paid across two tax months, they correctly get two.
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.
