No. But it is highly recommended. If you are a subcontractor working for a CIS registered contractor, you should be registered with HMRC. If not, the contractor will deduct tax at a higher rate. Being registered allows you to pay tax at the standard rate, which can save you money. We can help you get registered and avoid unnecessary deductions.
