MTD for Income Tax: What It Means for Tradespeople
A tailored guide for builders, plumbers, electricians, and contractors
If you’re a builder, plumber, electrician, or contractor, the way you report your taxes to HMRC is about to change fundamentally. From April 2026, Making Tax Digital (MTD) for Income Tax will replace the annual Self Assessment return with quarterly digital updates [1]. For many tradespeople who still rely on handing over a year’s worth of receipts in one go, this shift to digital record-keeping may prove a real challenge [2]. This guide explains exactly what it means for your trade business.
What is Making Tax Digital for Income Tax?
Making Tax Digital (MTD) is HMRC’s programme to move tax reporting and record-keeping into the digital age [3]. It already applies to VAT-registered businesses, and from April 2026 it’s being rolled out for those reporting Income Tax from self-employment [1].
Under MTD, you’ll need to [1][3]:
- Keep digital records of all your income and expenses using MTD-compatible software
- Submit quarterly updates to HMRC summarising your income and expenses
- File a final declaration at the end of the tax year (replacing your current Self Assessment)
When Does MTD Apply to You?
The Phased Rollout
MTD for Income Tax is being introduced in stages based on your total gross income from self-employment and property (combined) [1]. This is your qualifying income – the total before deducting any expenses [6].
| Qualifying Income | Based on Tax Year | Mandatory From |
|---|---|---|
| Over £50,000 | 2024/25 | 6 April 2026 [1] |
| Over £30,000 | 2025/26 | 6 April 2027 [1] |
| Over £20,000 | 2026/27 | 6 April 2028 [1] |
Example for a Tradesperson:
A plumber earns £45,000 from self-employment and also has a rental property generating £8,000 per year. Combined income = £53,000. This means MTD applies from April 2026 [1].
How HMRC Decides
The income threshold is assessed based on your most recent tax return. For the first phase (April 2026), HMRC is using your 2024/25 tax return figures [1][3]. The sooner you file your 2024/25 return, the more time you’ll have to prepare [1].
What MTD Requires You to Do
1. Keep Digital Records
You must maintain digital records of all your income and expenses using MTD-compatible software [1]. This means [6]:
- Recording the amount, date, and category of each transaction
- Keeping records for each sole trade business separately
- If you have both trade and property income, separate records for each
2. Submit Quarterly Updates
You’ll submit a summary of income and expenses to HMRC four times per tax year [1].
| Quarter | Period Covered | Submission Deadline |
|---|---|---|
| Quarter 1 | 6 April – 5 July | 7 August [1] |
| Quarter 2 | 6 July – 5 October | 7 November [1] |
| Quarter 3 | 6 October – 5 January | 7 February [1] |
| Quarter 4 | 6 January – 5 April | 7 May [1] |
You can choose to align your quarters to the calendar year (1 April – 30 June etc.) if this makes administration easier [1][6].
Quarterly submissions are simply a record of transactions for the period [6]. There is no requirement to make tax adjustments (like deciding whether expenditure is allowable), and no tax payments are calculated based on these updates [6].
3. File a Final Declaration
After the fourth quarterly update, you’ll submit a final digital declaration by 31 January following the end of the tax year [1][6]. This:
- Applies necessary adjustments to your self-employment income [1]
- Discloses any additional income sources
- Claims allowances and reliefs
- Calculates the tax due [1]
This replaces your current Self Assessment return for the in-scope parts of your income [3].
What This Means for Tradespeople
1 The End of the “Shoebox of Receipts”
For many sole trader subcontractors that still rely on handing over a year’s worth of receipts in one go, the shift to digital record-keeping and quarterly updates may prove a real challenge [2]. From 2026, paper-based or manual systems won’t cut it [2].
2 Tracking Job-by-Job Profitability
The upside? Digital records give you real-time visibility of your finances [7]. You’ll be able to see exactly how profitable each job is – information that’s gold dust for pricing future work.
3 Managing Material Costs
If you buy materials for each job, you’ll need to record these expenses digitally as they happen. Apps that let you photograph receipts at the trade counter will become essential tools [5].
4 Cash Payments Still Need Recording
Many tradespeople still receive cash payments for smaller jobs. Under MTD, every pound must be recorded digitally – including cash. No more “off-the-books” work.
What Records You Need to Keep Digitally
| Income to Record | Expenses to Track |
|---|---|

Choosing the Right Software for Your Trade
Software Options
You must use HMRC-approved MTD-compatible software [1]. Options include [6]:
| Software Type | Description | Best For |
|---|---|---|
| Cloud Accounting (Xero, QuickBooks, Sage, FreeAgent) |
Full accounting with bank feeds, invoicing, receipt scanning [6] | Tradespeople wanting all-in-one solution |
| Spreadsheets + Bridging | Keep using spreadsheets but connect via bridging software [1] | Those who can’t abandon existing spreadsheet systems |
| Free Software | Basic MTD-compatible tools [9] | Simple businesses with low transaction volumes |
What to Look For
The “Digital Links” Rule
If you use multiple software products (e.g., a spreadsheet for records and bridging software to submit), they must be digitally linked [3]. You cannot use manual copy-and-paste to move data between systems [3]. Allowed methods include [1]:
- CSV import/export
- API connections
- Linked cells in spreadsheets
Penalties for Missing Deadlines
Points-Based System
MTD introduces a new penalty regime [1]:
- Each late quarterly update earns you one penalty point [1]
- Four points incur a £200 fixed penalty [1]
- Points expire after two years of good compliance [1]
Late Payment Penalties
Tax payments remain due by 31 January [1]. Late payments attract [1]:
- 3% penalty on tax outstanding 15 days after deadline
- Further 3% penalty at 30 days
- 10% per year daily penalty for tax outstanding beyond 30 days
- Plus late payment interest
For the first year (2026/27), HMRC won’t issue late submission penalties for quarterly updates [1]. However, late final declarations and late payments ARE still subject to penalties [1]. Use this grace period to build good habits.
Exemptions: When You Don’t Need to Comply
Exemption from MTD applies automatically to [1]:
- Individuals without a National Insurance Number
Other exemptions are available by applying to HMRC for those who genuinely cannot use digital services due to [1][9]:
- Age, disability, or health conditions
- Living in an area with poor internet connectivity
- Religious beliefs preventing electronic communication
Based on the MTD for VAT experience, only a small percentage of businesses were granted exemptions – these are reserved for genuinely exceptional circumstances, not general reluctance to use technology [1].
Practical Tips for Tradespeople
Tip 1
Check Your Income
Review your 2024/25 gross income. If it exceeds £50,000, you’re in the first wave [3]
Tip 2
Use Separate Bank Accounts
Keep business and personal spending separate. Link bank feeds to your software [1]
Tip 3
Scan Receipts Immediately
Use your phone to photograph receipts at the trade counter – don’t wait [5]
Tip 4
Record Cash Payments
Every cash job must be recorded digitally. Use your software’s mobile app on site
Tip 5
Set Calendar Reminders
Mark quarterly deadlines (7 Aug, 7 Nov, 7 Feb, 7 May) in your phone now [1]
Tip 6
Start Early
Begin using digital records now, even if you’re not mandated yet. The pilot scheme is open [1]
Common Questions from Tradespeople
? What if I have multiple trades (e.g., building and plumbing)?
You need separate digital records for each trade business [6]. Some software (like Xero Simple) offers multi-business support within one licence [5].
? Can I still use my van logbook?
Yes, but you must record business mileage digitally. Many apps now offer automatic mileage tracking using your phone’s GPS [5].
? What about materials bought for a job that spans quarters?
Record the expense when you pay for it. The quarterly update captures transactions in the period they occur, regardless of when the job finishes [6].
? What if I make a mistake in a quarterly update?
You can correct errors in the next quarterly submission rather than amending the earlier one [6].
