CIS and Making Tax Digital can work alongside each other. Here’s what that means for construction subcontractors in Somerset.
If you’re paid under the Construction Industry Scheme, your contractor will usually deduct 20% from your labour payment, or 30% if you’re not registered for CIS. Some subcontractors have gross payment status, so no CIS is deducted.
Your contractor should give you a monthly CIS statement showing what you were paid and what was deducted. Keep these statements digitally with your own sales and expense records. Keep labour, materials and plant hire clearly itemised too, as CIS treatment can differ between materials and the labour element of your invoice.
MTD quarterly updates are summaries of your income and expenses. They don’t require a tax payment, and CIS deductions aren’t dealt with through these updates. They’re taken into account when your annual tax position is worked out.
CIS and MTD work alongside each other. If your contractor already uses CIS-capable payroll and RTI software, there’s nothing special they need to do for MTD.
