Register for CIS UK – Contractor & Subcontractor CIS Registration

Registration for CIS (Construction Industry Scheme) – Clear, Compliant and Supportive

Register for CIS UK if you work in the construction industry as a contractor or subcontractor. Audit Consulting Group helps businesses complete CIS registration quickly and stay compliant with HMRC.

What Is CIS and Why Does Registration Matter?

The Construction Industry Scheme (CIS) is an HMRC scheme requiring businesses to register for CIS UK before making or receiving construction payments. It requires contractors to deduct tax at source from payments made to subcontractors. These deductions are sent straight to HMRC as advance tax and National Insurance.

• If you’re subcontractor-CIS registered, contractors deduct 20%.
• If you’re not registered, they deduct 30%.
• Contractors themselves must register for CIS if they employ subcontractors or spend more than £3 million on construction in a year.

Many subcontractors prefer to register for CIS tax, to keep 10% more cash in hand each payment — and later adjust on their personal tax return.

CIS Deduction Rates

• 20% deduction – CIS registered subcontractors
• 30% deduction – Not registered
• 0% deduction – Gross payment status

Registering for CIS reduces deductions and improves cash flow.

Gross Payment Status

Eligible subcontractors may receive:

• 0% CIS deductions
• Full payment from contractors
• Improved cash flow

We help clients apply for gross payment status.

Who Must Register for CIS UK

You must register if you:

• Work as subcontractor in construction
• Hire subcontractors
• Spend over £3 million on construction
• Operate construction limited company
• Provide labour-only services

What Does “CIS Registered” Mean?

When you are CIS registered UK, HMRC recognises you as either:

• A CIS subcontractor: eligible for deductions at just 20%, or possibly gross payment status (no deductions) if you meet criteria.
• A CIS contractor: authorised to make deductions and submit CIS monthly returns.

In both cases, being correctly registered avoids higher deductions (30%) and HMRC penalties. It also signals professionalism to clients and contractors alike.

How to Register for CIS — Step by Step

Subcontractor Registration

1. Log in to your Government Gateway account.
2. Select ‘Construction Industry Scheme – Subcontractors’.
3. Complete the details:
   • UTR (Unique Taxpayer Reference)
   • NI number
   • Business/trading name
   • Start date of construction work
   • Type of work performed.
4. Submit online or use CIS301 if applying by post.
5. Once approved, your UTR acts as your CIS registration number.

You can also apply for gross payment status during this step if you qualify.

Contractor Registration

1. Ensure you’re registered as an employer within PAYE.
2. Use your Government Gateway account to register for CIS as a contractor under the ‘Employer’ menu.
3. HMRC sends you a letter with your PAYE reference and confirmation of CIS contractor status.

Once registered, you’re required to verify subcontractors, make correct deductions, submit CIS monthly returns, and issue payment statements.

What You’ll Need to Register

• UTR number
• National Insurance number (or company registration number if a business)
• Trading name (if different from business name)
• VAT number, if applicable
• Business start date and role (contractor or subcontractor)
• Contact details and Government Gateway login

Common Mistakes to Avoid

Many businesses face penalties due to:

• Failing to register early before starting work
• Misidentifying yourself as contractor or subcontractor (or both)
• Using the wrong rates (30% deduction instead of 20%)
• Forgetting to submit monthly CIS returns
• Not keeping proper records — a requirement for three years
• We help you avoid these issues by handling registration, set-up, and ongoing compliance properly.

What Happens After You Register?

As a Subcontractor:

• Contractors verify your CIS status online before first payment.
• You receive monthly deduction statements—essential for filing your tax return.
• If needed, apply for gross payment status later.

As a Contractor:

• Deduct 20 or 30% as appropriate from subcontractor payments.
• Submit CIS returns to HMRC by the 22nd of the following tax month.
• Provide payment and deduction statements to each subcontractor within 14 days
