Introduction: The Shift to MTD (Making Tax Digital) in The UK
Making Tax Digital is HMRC’s long-awaited initiative to move the UK’s tax system into the digital world. This system is designed meticulously to make tax administration more effective and efficient, as well as simpler for taxpayers to get their taxes right. Making Tax Digital has already been implemented for VAT; the next phase is for self-employed individuals, including those working in the construction industry, especially sole traders and subcontractors operating under the Construction Industry Scheme (CIS).
As a CIS worker or subcontractor, we understand the hustle you face throughout the year with complex tax deductions, compliance and other tax obligations, along with fluctuating income.
This blog aims to help business owners understand how Making Tax Digital for Income Tax Self-Assessment affects them, including key dates, obligations, and benefits, so they can stay compliant and reap the rewards of going digital.
Why is the UK Government Implementing MTD?
The main goal behind MTD is to reduce tax errors and boost efficiency by replacing outdated manual processes with digital systems. HMRC estimates that tax mistakes cost the government billions each year, which is often due to human error, missed deadlines, or incorrect recordkeeping.
MTD promotes real-time tax reporting and supports the fight against both inadvertent mistakes and intentional tax evasion by mandating digital submissions and frequent updates. The organisation and clarity that digital tools offer will be helpful to construction professionals who must manage several projects and payments. Additionally, maintaining digital records helps business owners plan and budget more effectively by providing them with more accurate tax estimates throughout the year.
What are the Key Dates and Timetable?
The government is rolling out MTD for Income Tax Self-Assessment (ITSA) in phases, giving businesses crucial time to prepare:
- From April 2026, self-employed individuals and landlords with an annual income over £50,000 will be required to comply with MTD for ITSA.
- From April 2027, the threshold will be lowered to include those earning over £30,000 per year. Although partnerships and those earning below these thresholds are not yet included, HMRC plans to bring them into the system in the future. A pilot programme is currently in the run, allowing some people to test the system voluntarily and provide feedback. It’s a useful option for those wanting to prepare early and get ahead.
Who Else Must Use Making Tax Digital for Income Tax Self-Assessment (ITSA)?
If you are a sole trader or landlord earning above £50,000 from April 2026 or above £30,000 from April 2027, you’ll be legally required to follow MTD for ITSA.
This includes many self-employed workers in construction, especially those operating through CIS or managing separate property income on the side.
In the future, MTD will expand to cover partnerships, smaller businesses, and other income types, but HMRC has not released those timelines yet. If you are close to the income thresholds, it’s wise to start planning now so you are not caught off guard.
Which Software Helps CIS Workers and Subcontractors Comply with MTD?
To comply with MTD, you must use HMRC-approved software to keep digital records and submit tax updates. Free spreadsheets and manual entries will not be enough.
When selecting software, businesses should look for:
- Real-time submissions and automatic updates
- User-friendly dashboards
- Integration with current accounting systems
- Features that support CIS deductions, project-based costs, mileage tracking, and mobile access for teams on the go.
We often recommend that our clients use the leading MTD-compliant software, QuickBooks and Xero.
- QuickBooks is known for its simple interface, real-time bank feeds, and helpful construction features like job costing.
- Xero offers powerful reporting, seamless integrations, and great scalability for growing firms.
Both provide quarterly update functionality, help reduce manual errors, and can save hours of paperwork, which is a huge win for busy site workers and contractors.

How MTD Can Benefit Construction Businesses?
While MTD may seem like an administrative burden at first, it actually comes with significant benefits for those in construction:
- Better financial visibility: Digital records allow you to track your income and expenses in real time, helping you stay on top of your finances, especially if you have irregular income.
- Fewer errors and penalties: Automation reduces the risk of mistakes, missed claims, or late submissions, all of which can lead to penalties.
- Time-saving automation: Say goodbye to piles of receipts and spreadsheets. Automated bank feeds, invoicing, and reporting, all of which save valuable time.
- Improved cash flow: Quarterly updates help you anticipate tax bills more accurately and plan payments in advance.
- Mobile-friendly bookkeeping: Most MTD software works well on mobile devices, ideal for construction workers always on the move.
