A Unique Taxpayer Reference (UTR) number is a 10-digit identifier issued by HM Revenue & Customs (HMRC) in the UK. It’s used to track individuals and businesses for tax purposes, especially when filing a Self Assessment tax return. If you're self-employed, a sole trader, a landlord, or a company director, you’ll need a UTR to report income that isn’t taxed at source. You can find your UTR on HMRC correspondence, such as tax returns, payment reminders, or in your Personal Tax Account

CIS registration refers to signing up for the Construction Industry Scheme (CIS), a UK tax system that applies to contractors and subcontractors in the construction sector. Under CIS, contractors deduct tax from subcontractors' payments and pass it to HMRC as advance tax payments. The standard deduction rates are: 20% for registered subcontractors 30% for unregistered subcontractors 0% if subcontractors have gross payment status, meaning they meet HMRC’s conditions for receiving full payments without deductions

Anyone involved in construction work in the UK may need to apply for CIS registration, depending on their role: Contractors must register if they pay subcontractors for construction work Subcontractors can register to avoid higher tax deductions (30% instead of 20%) on payments received.
