Digital Records HMRC Demands: What Tradespeople Get Wrong

What exactly does HMRC mean by "digital records" — and is a photo of a receipt on your phone actually enough?

For self-employed tradespeople preparing for Making Tax Digital for Income Tax Self Assessment (MTD ITSA), this is not a trivial question. HMRC's guidance runs to thousands of words, yet it still manages to leave the most practical questions unanswered. What counts as a valid digital record for a plumber buying pipe fittings at a trade counter? Does a bank statement screenshot satisfy the requirement? Can you keep records in a spreadsheet, or does it have to be dedicated software?

The answers matter. From April 2026, sole traders earning above £50,000 must use MTD-compatible software and maintain digital records or face a penalty regime that starts at £200 per year and escalates quickly. Tradespeople turning over £50,000 to £80,000 are squarely in the first wave.

The Rule HMRC States and the Reality Tradespeople Face

HMRC's published guidance states that digital records must include: the date of the transaction, the amount, and the category (for example, goods for resale, travel, or tools and equipment). That sounds simple. In practice, a self-employed electrician buying cable and fixings at a builders' merchant faces a more complicated picture.

Does the merchant's till receipt — photographed and stored in WhatsApp — count? No. The photograph creates an image file, not a digital record in the MTD sense. The data inside that image has not been captured by any software. Unless an app has read and structured that data (using OCR technology, for example), HMRC's requirement has not been met.

This is a distinction that caught many tradespeople off guard when HMRC first piloted MTD for VAT, and the same confusion is now arriving for income tax. If you want to understand how receipt-scanning technology actually performs in practice, Automatic Receipt Scanning Tax UK: Does It Actually Work? covers the evidence honestly.

What HMRC Actually Requires You to Record

HMRC specifies the following data points for each transaction in a self-employment business:

• Date of the sale or purchase
• Amount received or paid
• Category of income or expense, mapped to HMRC's property income or self-employment categories

For income, a tradesperson must record each payment received, the date it was received, and the nature of the work (for example, labour, materials supplied to customer, or a combined job). For expenses, the category matters because different expense types receive different tax treatment.

What does not need to be recorded at transaction level is the customer's name and address for income tax purposes, which is different from VAT record-keeping. That is one minor simplification. Everything else is more demanding than many tradespeople expect.

The Categorisation Problem

Here is where even diligent tradespeople run into trouble. HMRC's self-employment expense categories include:

• Cost of goods bought for resale or goods used
• Construction industry payments to subcontractors
• Wages, salaries, and other staff costs
• Car, van, and travel expenses
• Rent, rates, power, and insurance costs
• Repairs and maintenance of property and equipment
• Phone, fax, stationery, and other office costs
• Advertising and business entertainment costs
• Interest on bank and other loans
• Bank, credit card, and other financial charges
• Irrecoverable debts written off
• Accountancy, legal, and other professional fees
• Other business expenses

A self-employed tradesperson buying a van part might record it under vehicle maintenance. But if the van is also used privately, only the business proportion is deductible, and the digital record should reflect that split. Software that simply imports a bank transaction and labels it "debit £85.00" has not done the job.

This categorisation burden is one reason MTD Quarterly Update Mistakes That Cost Sole Traders Real Money identified miscategorisation as one of the most common and costly errors in early MTD submissions.

Spreadsheets: Allowed, But With Conditions

One of the most persistent myths in the tradesperson community is that a well-maintained Excel spreadsheet is MTD-compliant on its own. It is not, but that does not mean spreadsheets are off the table entirely.

HMRC permits the use of spreadsheets for record-keeping, provided the spreadsheet is connected to MTD-compatible software via what is called a "bridging solution." The bridging software reads data from your spreadsheet and submits it to HMRC in the required format. Without that bridge, submitting a tax return from a spreadsheet remains a manual process and does not comply with MTD.

The practical implication: a spreadsheet-only workflow requires you to pay for bridging software on top of maintaining the spreadsheet yourself. For most tradespeople, this is more effort and often more cost than simply using an all-in-one MTD app from the start.

The Bank Feed Trap

Many accounting apps now offer automatic bank feeds, pulling transactions directly from your current account into the software. This feels like digital record-keeping. It is a starting point, not an endpoint.

A bank feed import gives you a date and an amount. It does not give you a category, a description of the work, or any indication of whether a purchase was wholly for business use. Every imported transaction still needs to be reviewed and categorised by you or your accountant.

For a tradesperson with 200 to 400 transactions per quarter — common for anyone buying materials regularly, paying fuel, and issuing multiple invoices per week — that review process is not trivial. Left undone, a bank feed full of uncategorised transactions is not a set of digital records in any meaningful sense. It is a list of debits and credits waiting for a human to do the actual work.

What Good Digital Records Actually Look Like

To make this concrete, consider a self-employed heating engineer turning over £65,000 a year. In a typical week, they might:

• Issue three invoices to customers (labour plus parts)
• Buy materials at two different merchants, paying by card
• Fill the van with fuel twice
• Pay a subcontractor for one day's labouring
• Renew a tool insurance policy online

Under MTD, each of these transactions needs to be in the software with a date, amount, and correct category before the next quarterly update deadline. The subcontractor payment, in particular, needs to be flagged correctly; if this tradesperson operates under the Construction Industry Scheme, there are additional considerations covered in detail in MTD for Construction Workers: CIS and the Double Reporting Trap.

A compliant week's records, done properly, might take fifteen minutes if the software is well-designed and the tradesperson is consistent. Left until the quarterly deadline, three months of transactions takes significantly longer and mistakes become more likely.

The quarterly deadline is not just an administrative formality. Errors in quarterly updates can cascade into the end-of-year declaration and require corrections that HMRC may query.

The Record Retention Rule Nobody Mentions

Digital records under MTD must be kept for at least five years after the 31 January filing deadline for the relevant tax year. For the 2026/27 tax year (the first year many tradespeople will be in MTD), records must be retained until 31 January 2033.

This means the software you choose, or the spreadsheet you maintain, needs to be accessible and readable for years after the event. If you stop paying for a software subscription, you may lose access to historical records stored in that system. Before choosing any MTD software, check the data export options. Can you download your records in a standard format (CSV, PDF) at any time? If the answer is unclear, ask before you subscribe.

The Paper Receipt Question, Settled

To settle the question once and for all: paper receipts stored physically do not meet HMRC's digital records requirement, even if you intend to photograph them later. The photograph stored in a camera roll does not meet it either. A photograph that has been processed by OCR software, with the data (date, amount, supplier) extracted and saved in your MTD-compatible software, does meet it.

Practically speaking, the simplest compliant workflow for most tradespeople is:

1. Take a photograph of the receipt immediately using your MTD app
2. Let the app extract the data automatically
3. Review and confirm the category
4. Discard the paper receipt (though keeping it as a backup for disputes is sensible)

This takes under a minute per transaction at the point of purchase, which is far less painful than reconstructing three months of receipts the night before a quarterly deadline.

Tradespeople With Mixed Income

Some tradespeople have more than one income stream: their main trade, perhaps some rental income from a property, and possibly a small amount of PAYE income from a part-time role. MTD treats each source separately.

Self-employment income is reported through one set of digital records. Property income requires its own separate digital records under MTD for landlords. PAYE income is reported by the employer and does not require digital records from you, but it does affect your overall tax position.

If this describes your situation, MTD for Therapists UK: The Income Problem HMRC Ignores deals with a similar multi-income complication, and the logic applies equally to tradespeople with mixed income sources.

The Practical Bottom Line

Remember the question at the start: is a photo of a receipt on your phone enough? Now you know the answer is no, unless an app has read that image and structured the data into a compliant digital record.

For self-employed tradespeople, the digital records requirement under MTD ITSA is not an administrative tick-box. It is a fundamental change to how income and expenses need to be captured, categorised, and stored. Done consistently, in small daily habits rather than quarterly panic sessions, it is manageable. Done badly, or not done at all, the penalty points system will find you.

The April 2026 deadline for sole traders earning over £50,000 is close enough that starting now means arriving prepared rather than scrambling. TapTax is built specifically for sole traders who want to meet HMRC's digital records requirements without wading through software designed for accountancy firms.
