From April 2026, the way many Construction Industry Scheme (CIS) workers report their income to HMRC will change significantly. If you are a CIS contractor earning over £50,000 per year, you will be required to follow Making Tax Digital (MTD) for Income Tax Self Assessment (ITSA).

This is one of the biggest changes to the UK tax system in recent years and will affect how self-employed construction workers keep records, report income, and manage their tax obligations.

In this guide, we’ll explain what Making Tax Digital means for CIS workers, who needs to comply, and how you can prepare before the April 2026 deadline. We’ll also show how our MTD for CIS service at CloudAccountant.co.uk can help you stay compliant without increasing your workload.

Making Tax Digital (MTD) is HMRC’s initiative to modernise the UK tax system by requiring taxpayers to keep digital records and submit updates more frequently.

Under the current system, most CIS workers complete one Self Assessment tax return each year. However, once MTD for Income Tax is introduced, eligible individuals will need to submit updates to HMRC throughout the year.

According to HMRC guidance, the aim of Making Tax Digital is to reduce errors and make tax administration more efficient. You can read more about the programme on the official HMRC page here:

For CIS workers, this means a shift from annual reporting to ongoing digital reporting.

From April 2026, Making Tax Digital for Income Tax will apply to self-employed individuals and landlords with total income above £50,000.

This includes many CIS subcontractors working in construction, particularly those operating as sole traders.

If you fall into this category, you will need to:

• Keep digital records of your income and expenses

• Use HMRC-recognised accounting software

• Submit quarterly updates to HMRC

• Complete a final declaration at the end of the tax year

Further thresholds will be introduced later, meaning even more CIS workers will eventually be brought into the system.

Many CIS workers are used to providing their records once a year to an accountant, who then prepares and submits their Self Assessment return.

With MTD, the process will become more frequent and structured.

Instead of one annual submission, you will now have to send four quarterly updates to HMRC showing your income and expenses for that period.

At the end of the tax year, you will also submit a final declaration, confirming your overall income and tax position.

For busy construction workers, this change could create additional administrative work if you are not prepared.

That’s why having the right systems and support in place is essential.

CIS contractors face unique tax challenges that make Making Tax Digital more complicated than it may appear.

For example, CIS workers often:

• Receive payments from multiple contractors

• Have CIS deductions taken at source

• Work on irregular contracts or projects

• Incur a wide range of allowable expenses

Keeping accurate records of this activity throughout the year can be time-consuming, especially when you are focused on working on site.

Without proper systems, there is also a risk of:

• Missing quarterly submission deadlines

• Submitting incorrect figures

• Receiving penalties from HMRC

This is where professional support can make a significant difference.

At CloudAccountant.co.uk, we specialise in supporting CIS workers and construction contractors with their tax obligations.

To help clients prepare for the upcoming changes, we’ve launched a dedicated MTD for CIS service designed specifically around how CIS workers operate.

Our service ensures you remain fully compliant with HMRC while reducing the amount of admin you have to deal with.

You can find full details of the service here:

Our MTD for CIS service starts from just £45 plus VAT per month, making it an affordable way to stay compliant with the new rules.

For this monthly fee, we will:

• Help you set up MTD-compliant accounting software

• Ensure your CIS income and allowable expenses are recorded correctly

• Prepare and submit your quarterly updates to HMRC

• Complete your final declaration at the end of the tax year

• Provide ongoing support from our accountancy team

This means you can focus on your work while we take care of the reporting requirements.

To celebrate the launch of the service, we are also offering a free month to anyone who signs up before April, meaning you won’t pay anything for May.

To comply with MTD rules, you must use HMRC-recognised software that can connect directly to HMRC’s systems.

One of the most popular platforms for contractors is FreeAgent, which allows you to:

• Track income from contractors

• Record business expenses

• Maintain digital records

• Submit tax updates directly to HMRC

At CloudAccountant.co.uk, we can provide a FreeAgent licence for £12 plus VAT per month, including full setup and training so you know how to use the software properly.

Alternatively, FreeAgent is included free when you open a business bank account with NatWest, RBS, Ulster, or Mettle, which can help reduce your costs.

While some contractors prefer to manage their own bookkeeping, others would rather focus entirely on their work.

For CIS workers who want a fully hands-off solution, we also offer ongoing bookkeeping support for £20 per month.

With this service, we will keep your CIS income and expenses organised and recorded throughout the year, ensuring your records remain accurate and compliant with HMRC requirements.

This makes quarterly submissions much simpler and significantly reduces the risk of errors.

Although April 2026 may seem far away, preparing early has several benefits.

Getting ready now allows you to:

• Become familiar with digital record keeping

• Avoid a last-minute rush before the deadline

• Ensure your records are accurate from day one

• Reduce the risk of HMRC penalties

It also means you can take advantage of support services before demand increases closer to the implementation date.

Making Tax Digital will change how CIS workers manage their taxes, but it doesn’t have to make things more complicated.

With the right support, the transition can be smooth and stress-free.

At CloudAccountant.co.uk, our dedicated MTD for CIS service ensures your records remain compliant, your submissions are handled correctly, and your tax obligations are taken care of.
