Are You Registered Under CIS?
If you work in construction in the UK — as a sole trader, limited company or partnership — you may need to register for CIS. Contractors are required to deduct tax from subcontractors and submit monthly reports. Subcontractors can reclaim deductions or pay reduced tax rates.
Brathwaite Accountants helps you register, manage, and stay fully compliant with HMRC requirements so you can focus on the job.
Avoid Penalties and Get Paid on Time
Late or incorrect CIS returns can lead to heavy penalties and payment delays. We ensure everything is filed correctly, on time, and fully reconciled with your payments. We also provide deduction statements for subcontractors and help claim back any overpaid tax.
Whether you're a sole contractor or run a growing firm, we ensure every submission meets HMRC requirements.
