How to Get a CIS Card

At Towerstone Accountants we provide specialist CIS accountancy services for contractors and construction businesses across the UK. We created this webpage for subcontractors and contractors who want clear guidance on the Construction Industry Scheme, including registration, deductions, refunds, and ongoing reporting obligations. Our aim is to help you stay compliant with HMRC, avoid costly errors, and understand how CIS affects your tax position.

When someone asks me how to get a CIS card what they are usually really asking is how to get themselves recognised properly under the Construction Industry Scheme so they can work without unnecessary deductions delays or awkward conversations with contractors. The phrase CIS card is still widely used across the industry even though the physical card itself is no longer issued in the way it once was and that alone causes a great deal of confusion.

I have spent years working with subcontractors contractors and small construction businesses and I can say with confidence that understanding how the CIS system works and how to get yourself correctly registered is one of the most important early steps you can take. It affects how much tax is taken from you how smoothly you get paid and how HMRC views your compliance from day one.

In this article I am going to explain what people really mean by a CIS card how the system works today how to register properly and what evidence you may need to provide to contractors. I will also share practical guidance based on real situations I see regularly so you can avoid the common mistakes that trip people up.

What people mean by a CIS card today

Historically a CIS card was a physical card issued by HMRC that showed a subcontractor’s details and their deduction rate. Many long standing contractors still use the term and many subcontractors still ask for one but in reality HMRC no longer issues CIS cards in that format.

Today there is no plastic or paper CIS card. Instead your CIS status exists digitally within HMRC’s systems and contractors verify you directly with HMRC before paying you. When someone asks you for your CIS card they are really asking for confirmation that you are registered under CIS and what deduction rate applies to you.

This usually means they want

• Your full name or business name

• Your Unique Taxpayer Reference

• Confirmation that you are registered under CIS

• Confirmation of your deduction status

Understanding this upfront removes a lot of anxiety because many people worry they are missing a document that simply no longer exists.

Who needs to get a CIS card or CIS registration

CIS registration is required if you are carrying out construction work in the UK as a subcontractor and you are not paid through PAYE as an employee.

This applies to

• Sole traders working in construction

• Partnerships providing construction services

• Limited companies acting as subcontractors

• Labour only subcontractors

• Many specialist trades such as electricians plumbers plasterers roofers carpenters groundworkers and decorators

If you are genuinely employed and paid through PAYE then CIS does not apply. If you invoice for your work or are paid as a business then CIS almost certainly does.

One of the most common misunderstandings I see is people assuming that registering as self employed automatically registers them for CIS. It does not. CIS is a separate registration and must be done deliberately.

Why registering for CIS properly matters

Getting CIS registration right from the outset saves a great deal of trouble later. If you are not registered when you start work the contractor is legally required to deduct tax at 30 percent. That money is not lost but it can only be reclaimed later through a tax return which can put real pressure on cash flow.

If you are registered correctly the deduction is usually 20 percent and if you qualify for gross payment status there may be no deduction at all. Contractors are strict about this because HMRC places the compliance burden on them and they will not take risks.

From my experience contractors are far more willing to engage with subcontractors who understand CIS and can provide their details confidently and promptly.

How to register for CIS as a sole trader

If you are a sole trader the process is relatively straightforward but timing and accuracy matter.

First you must be registered as self employed with HMRC. This gives you a Unique Taxpayer Reference which is essential for CIS registration. Without a UTR you cannot be verified under CIS.

Once you have your UTR you can register for CIS. This can be done online through your Government Gateway account or by calling HMRC. Online registration is usually quicker and gives you confirmation more efficiently.

During registration HMRC will ask for

• Your full name

• Your National Insurance number

• Your UTR

• Your business details

• The type of construction work you do

Once registered HMRC will confirm your CIS status and from that point contractors can verify you.

I always advise clients to register for CIS as soon as they know they will be doing construction work rather than waiting until a contractor asks because delays can result in higher deductions.

How to register for CIS as a limited company

If you trade through a limited company the process is slightly different and this is an area where mistakes often happen.

The company itself must be registered for CIS. The director or directors also need to ensure the company has a UTR for Corporation Tax. Registering the company with Companies House does not automatically complete this step.

Once the company has its Corporation Tax UTR you can register the company for CIS. This again can be done online or by phone.

HMRC will ask for

• The company name and registration number

• The company UTR

• Details of the directors

• The nature of the construction work

Once registered the company will be treated as a subcontractor under CIS and contractors will verify the company rather than the individual director.

A common error I see is directors giving contractors their personal UTR instead of the company UTR which leads to failed verification and incorrect deductions.

What happens after you register for CIS

Once you are registered HMRC records your CIS status and contractors can verify you. Verification is done by the contractor and confirms the deduction rate that should be applied.

You do not receive a physical card but you may receive written confirmation from HMRC and your online account will show your status. This confirmation is effectively your modern CIS card.

When a contractor verifies you HMRC will respond with one of three outcomes

• Deduct at 20 percent

• Deduct at 30 percent

• Pay gross with no deduction

This outcome is what the contractor must follow regardless of any informal agreement.

Gross payment status and the CIS card question

Many people asking about a CIS card are actually hoping to obtain gross payment status. This allows you to be paid in full without deductions and is highly attractive for cash flow reasons.

Gross payment status is not automatic and must be applied for. To qualify you must meet several conditions including

• Carrying out construction work in the UK

• Meeting minimum turnover thresholds

• Having an excellent compliance history with HMRC

The compliance requirement is the most important. All tax returns must be submitted on time and all taxes paid when due. Even a single late filing can result in rejection or withdrawal of gross status.

If you are granted gross payment status this will show in HMRC’s system and contractors will see it when they verify you. Again there is no physical card issued.

What contractors will ask you for instead of a CIS card

In practice when a contractor asks for your CIS card they will usually ask for specific details so they can verify you.

This typically includes

• Your full legal name or company name

• Your UTR

• Your National Insurance number or company registration number

• Confirmation of whether you are a sole trader or limited company

Providing this promptly makes verification straightforward and builds confidence.

I always advise subcontractors to keep these details recorded securely and accessible because you will be asked for them regularly especially when working with new contractors.

Common problems when trying to get a CIS card

There are several issues I see repeatedly when people try to get themselves CIS ready.

One is registering too late which leads to 30 percent deductions that could have been avoided. Another is giving incorrect details such as the wrong UTR or mixing up personal and company information.

I also see people assume they are registered because they have worked under CIS before. Registration does not carry over automatically if you change business structure for example moving from sole trader to limited company requires a new CIS registration.

Finally there is confusion around employment status. Some people are incorrectly treated as subcontractors when they should be employees and this can cause compliance issues beyond CIS itself.

How long CIS registration takes

In most cases CIS registration is confirmed quickly particularly when done online. I often see confirmation within a few days although HMRC advises allowing longer during busy periods.

Verification by contractors is instant once registration is active. This means timing is important if you are about to start a new contract.

I usually recommend registering at least a couple of weeks before starting work where possible to allow for any delays or corrections.

Keeping evidence of your CIS status

Although there is no physical CIS card I strongly recommend keeping evidence of your registration.

This may include

• Screenshots of your HMRC online account

• Confirmation letters or emails from HMRC

• Copies of CIS deduction statements showing your rate

These documents are useful if there is ever a dispute or if a contractor queries your status.

My experience helping people get CIS registered

From my own experience the people who have the smoothest time under CIS are those who treat registration as a core business setup task rather than an afterthought. Once registered properly CIS becomes routine and predictable.

The problems arise when registration is rushed misunderstood or ignored. In almost every case the fix is possible but it is always easier to do it right from the start.

Looking ahead and staying compliant

CIS compliance is becoming more closely monitored as HMRC increases its focus on digital reporting and cross checking. Contractors are under pressure to get it right and that pressure flows down to subcontractors.

Understanding that there is no physical CIS card and knowing how to register and evidence your status puts you ahead of the curve. It shows professionalism and makes you easier to work with which in construction matters more than many people realise.

If there is one piece of advice I would leave you with it is this, get registered early keep your details accurate and never assume CIS is sorted without checking. Doing that will save you time money and unnecessary stress as your work grows.
