The UK tax system is undergoing a significant transformation. The shift towards Making Tax Digital (MTD) is no longer a distant concept for contractors. It has become a fast-approaching reality that will significantly change how you interact with HM Revenue and Customs (HMRC).
Whether you are a CIS contractor or a sole trader, understanding these changes is crucial to streamlining your business operations and avoiding penalties. Let’s explore Making Tax Digital for contractors in detail. This blog highlights MTD for contractors, its rules, who are exempt from MTD, and how you can set up MTD.

What is Making Tax Digital (MTD)?
Making Tax Digital was originally launched to modernise Value Added Tax (VAT) reporting before expanding to Income Tax. This government initiative requires taxpayers to move their records online and use HMRC-compatible software for tax submissions.
Additionally, it has evolved into a sweeping digital overhaul of how businesses and individuals interact with HMRC.
Making Tax Digital aims to modernise tax administration by replacing annual paper-based filings with a more frequent digital-first approach.

How MTD Affects Contractors
Making Tax Digital for contractors introduces immediate obligations and upcoming compliance changes. MTD changes how contractors or subcontractors manage their tax reporting by requiring digital record-keeping and quarterly updates.
The rollout is phased based on the contractor’s qualifying income from self-employment and property. If you are working exclusively through an umbrella company (Pay As You Earn) or operate through a limited company, you are not directly affected by the Income Tax rules.
Note: According to HMRC Making Tax Digital rules for contractors, the mandate begins on 6 April 2026.
Impact on CIS Contractors
Construction Industry Scheme (CIS) workers face additional administrative changes under Making Tax Digital for contractors:
- Subcontractors must record gross income, expenses and CIS deductions digitally in real-time.
- Main contractors must keep digital records of all payments and deductions made to subcontractors.
- If you are a VAT-registered business already using MTD-compliant software, ensure your system is compatible with HMRC Income Tax requirements.
HMRC Making Tax Digital Rules for Contractors
Under MTD for Income Tax, contractors and subcontractors must keep digital records and make quarterly digital updates. This means, instead of submitting one Self Assessment annually, you submit digital updates of your business income and expenses every three months.
However, the annual obligation “final declaration” still applies under Making Tax Digital for contractors.
Digital Record Keeping for Contractors
Manual spreadsheets and paper receipts are no longer sufficient. You must use spreadsheets with “bridging” tools or HMRC-recognised software to record all transactions.
Quarterly Updates
Every three months, you must send reports of your income and expenses to HMRC. Send these reports through your chosen HMRC-approved MTD software.
Final Declaration
An end-of-year statement, submitted by 31 January, replaces the traditional Self Assessment to finalise tax position.
No Change in Payment
Although reporting frequency increases, tax payment dates remain the same. You still pay tax by 31 January and 31 July.
Does Making Tax Digital Apply to CIS?
Yes, MTD applies to CIS primarily through the new Income Tax rules. If you are a CIS subcontractor and your income is over £50,000, then you must keep digital records of invoices and expenses. Also, keep records of CIS deductions and submit quarterly reports to HMRC through HMRC-approved MTD software.
Even though you file your regular CIS returns, you must also report quarterly MTD updates accurately. This ensures accurate tax calculations and correct refunds at year-end.
Key Deadlines and Thresholds for Making Tax Digital for Contractors
The rollout of MTD for Income Tax Self Assessment (ITSA) is based on contractors’ qualifying income. A contractor or sole trader above specific thresholds must use MTD-approved software.
| Rollout Timeline | Income Threshold | Who is affected? |
| April 2026 | Over £50,000 | High-earning landlords and sole traders |
| April 2027 | Over £30,000 | Mid-range self-employed individuals |
| April 2028 | Over £20,000 | Remaining self-employed individuals |
Disclaimer: The above thresholds are based on gross qualifying income, not your profit. HMRC determines your start date based on the tax return filed two years before the mandate date.
Key MTD Deadlines 2026 for Phase 1
If your income exceeds £50,000, your first reporting cycle is as follows:
- 7 August 2026 is the deadline for the first Quarterly Update
- 7 November 2026 is the deadline for the 2nd Quarterly Update
- 31 January 2027 is the deadline for the final traditional Self Assessment tax return covering the 2025/26 tax year (pre-MTD).
- 7 February is the deadline for the 3rd Quarterly Update
- 7 May 2027 is the deadline for the 4th Quarterly Update
- 31 January 2028 is the deadline for your first MTD Final Declaration
Visit the official website of HMRC for comprehensive information regarding the MTD for Income Tax timeline.
Making Tax Digital For VAT
If a contractor is VAT-registered, they must follow MTD rules regardless of their turnover. Although the VAT registration threshold is currently £90,000, a business below this mark that is voluntarily registered must still comply with MTD for VAT.
Moreover, as of July 2025, plans for MTD for Corporation Tax have been officially scrapped. This means Limited Companies continue with their existing annual filing process.
How to Comply with MTD as a Contractor?
To comply with MTD for contractors, you must transition from an annual manual or paper-based reporting system to a digital system.
- You are legally required to keep digital records of your business transactions. Simple spreadsheets are only acceptable if digitally linked to HMRC via bridging software.
- You must use software that connects to the HMRC system. You can use accounting platforms like QuickBooks, FreeAgent, or Xero to handle your digital records and submissions.
- Under Making Tax Digital for contractors, you must send a summary of your income and expenses updated every three months.
- Submit your final declaration and claim allowance and reliefs.
Who is Exempt from Making Tax Digital?
MTD exemptions are broadly categorised into automatic exemptions and digital exclusion exemptions.
Automatic Exemptions
You are automatically exempt from Making Tax Digital for contractors for Income Tax if you fall into one of the following categories:
- Your gross qualifying income is below the threshold (£20,000 or less).
- You do not have a National Insurance (NI) number
- You are filing only as a personal representative, trustee or Lloyd’s member for your underwriting business.

- A mental or physical disability that prevents you from using smartphones or computers.
- Your beliefs are conflicting with electronic communication or digital record-keeping
