MTD for CIS workers: What construction workers need to know before 2026

Making Tax Digital is a government-led initiative that aims to modernise the UK tax system. Starting from April 2026, most self-employed individuals – including those working under the Construction Industry Scheme (CIS) – will need to submit their CIS Tax Return information digitally and quarterly to HMRC.

If you’re a CIS subcontractor earning over £50,000 annually, this applies to you.

Why It Matters for Construction Workers

As a CIS worker, your income and tax deductions can be irregular and complex. Under MTD, HMRC expects your tax details to be:

• Recorded digitally using MTD-compliant software
• Submitted every quarter, not just once a year
• Backed up by accurate income and expense tracking

This marks a big shift from the current system where many CIS workers rely on yearly submissions and paper records.

What’s Changing from April 2026?

Here’s a quick breakdown of what’s different under MTD:

Current System	MTD System (From April 2026)
Annual tax return via accountant or software	Quarterly digital submissions to HMRC
Paper or spreadsheet records	Cloud-based software required
One year-end summary	Quarterly updates + End of Period Statement (EOPS)
No legal need for software	Legal requirement to use approved tools

You’ll need to record your CIS payments, deductions, and expenses digitally as they happen. Which means no more leaving it all to the end of the year.

How Will This Affect CIS Tax Returns?

Here’s how your CIS work will be impacted:

• Quarterly tax reports are mandatory, even if your income fluctuates.
• CIS statements will need to be matched with your expense records in real time.
• You’ll need to track deductions, materials, tools, travel, and mileage using compliant software.
• You’ll still claim back your tax rebate but now through a more structured digital process.

With Tax2u, you’ll be able to upload your CIS statements, receipts, and invoices straight into the Tax2u platform and we’ll handle CIS Tax Return for you.

3 Big Challenges for Construction Workers

1. Irregular Income Construction jobs vary. One month you’re working full-time, the next it’s part-time. MTD still requires four submissions per year — even with variable income.
2. Lost Paperwork Receipts fade. Paper gets lost. Under MTD, you’ll need to photograph and store documents digitally to stay compliant.
3. Lack of Tools Many CIS workers don’t currently use any software. From 2026, using MTD-approved tools will be non-negotiable.
