CIS support in Bromley and South London
Practical Construction Industry Scheme support for contractors and subcontractors. We help you organise your records, manage monthly returns and understand deductions, with clear advice and fees agreed before work begins.
CIS returns and records for contractors
Paying subcontractors means keeping the right records and reporting payments correctly. We can help with CIS registration, subcontractor verification, deduction calculations, payment and deduction statements, and monthly returns, according to the service agreed with you. Before taking over, we review your current records and explain the information we need each month. You provide payment details and supporting documents to an agreed timetable, and review the figures before submission. We can also discuss overdue returns and missing records. CIS does not decide a worker’s employment status. We help you identify where a separate status review is needed, so employees are not treated as subcontractors simply because they work in construction.
CIS support for subcontractors
If a contractor deducts CIS from your payments, keeping invoices and payment and deduction statements together makes it easier to check your position. We help sole traders and limited companies reconcile their income, expenses and deductions.
For sole traders, CIS deductions are reported through Self Assessment. Limited companies use a different process through their PAYE scheme. We explain the route that applies to your business and can help with a potential repayment where the records support it. A refund is not guaranteed.
How we get started
- Tell us about your business. Book a free consultation and let us know whether you pay subcontractors, work as one, or both.
- Agree the work and fees. We review your setup, any outstanding returns and the records available before confirming the scope.
- Build a monthly routine. We agree when to receive your information, what you need to approve and the reporting tasks we will handle.
Your CIS questions
When is a monthly CIS return due?
The deadline is the 19th of the month following the tax month being reported. A CIS tax month runs from the 6th to the following 5th. For example, payments from 6 May to 5 June are reported by 19 June.
What if I have not paid any subcontractors?
You still need to tell HMRC. Depending on your circumstances, this can mean a nil return or an inactivity request. Let us know before the reporting deadline so we can agree the right action.
Does having CIS deductions mean my tax is fully paid?
No. CIS deductions are advance payments towards tax. Your final position depends on your business figures and circumstances. We reconcile the deductions against your records and explain any balance or potential repayment.
Can a limited company claim CIS deductions through Self Assessment?
Company deductions are handled through the company’s PAYE scheme and Employer Payment Summary, rather than a director’s personal Self Assessment. We can help review the records and any potential repayment through the appropriate process.
For the scheme rules, read HMRC’s Construction Industry Scheme guidance.
