Understanding MTD Requirements: What Actually Constitutes a “Digital Record”
A plain-English breakdown of what HMRC requires — and what it doesn’t — so you and your clients are fully prepared
One of the most common questions accountants and their clients ask about Making Tax Digital for Income Tax is deceptively simple: what exactly is a “digital record”? The answer matters enormously — because getting it wrong means either unnecessary panic or dangerous complacency. This guide cuts through the jargon to tell you precisely what HMRC requires, what is permitted, and where the grey areas lie.
Why the Definition Matters So Much
From April 2026, self-employed individuals and landlords with qualifying income above £50,000 must keep digital records and submit quarterly updates to HMRC using MTD-compatible software. From April 2027, the threshold drops to £30,000, and further expansion is planned thereafter.
But “digital records” is a term that causes real confusion. Some clients assume it simply means scanning paper receipts. Others believe their existing spreadsheet is already compliant. Many have no idea at all. As their accountant, providing a clear, authoritative answer is both a compliance obligation and a service differentiator.
Key Point: HMRC’s requirement is not simply that records exist in a digital format — it is that specific data fields are captured digitally, that records are maintained in a compatible system, and that digital links exist between that system and the software used to submit quarterly updates.
The Three Core Components of a Valid Digital Record
1 The Correct Data Fields Must Be Captured
HMRC specifies that digital records must contain certain minimum data fields for each transaction. For self-employed (business income and expenses), a digital record must include:
- The date of the transaction
- The category of income or expense (aligned to HMRC’s specified categories)
- The amount of the transaction
For property income, records must capture:
- The date of the transaction
- The amount of rental income received
- The category of allowable expenses
- The amount of each expense
Notably, HMRC does not require the name of the supplier or customer, the invoice number, or a description of what was purchased to be stored as part of the digital record — though good bookkeeping practice would recommend capturing these for your own purposes.
2 Records Must Be Held in a Functional Compatible System
The records must be maintained in software that is capable of submitting data directly to HMRC or linking digitally to software that can. This means:
- HMRC-recognised accounting software (e.g. QuickBooks, Xero, FreeAgent, Sage) — fully compliant when set up correctly
- Spreadsheets with bridging software — permitted, provided a functional digital link exists between the spreadsheet and the bridging tool that submits to HMRC
- Paper records, even if later typed up — not compliant; the digital record must be created at, or very shortly after, the point of transaction
- Photographs of receipts stored in a folder — not compliant on their own; the data must be extracted and entered into the system
3 Digital Links Must Be Maintained Between Systems
If a client uses more than one piece of software in their record-keeping process (for example, a receipt-capture app that feeds into a spreadsheet, which then connects to bridging software), each transfer of data between systems must be a digital link — not a manual re-keying of data.
A digital link means the data is transferred electronically — via an API connection, an automatic export/import, or a formula-driven link — without a human retyping figures from one system to another. Cut and paste is explicitly permitted by HMRC as a digital link. However, manually typing figures from one spreadsheet into another is not.
What Counts — and What Does Not
| Record Type / Method | MTD Compliant? | Notes |
|---|---|---|
| Cloud accounting software (Xero, QuickBooks, FreeAgent) | ✅ Yes | Provided software is MTD-compatible and correctly categorised |
| Spreadsheet + HMRC-recognised bridging software | ✅ Yes | Digital link must exist between spreadsheet and bridging tool |
| Bank feed data auto-imported into accounting software | ✅ Yes | Bank feeds count as digital links; still requires categorisation |
| Receipt scanning app (e.g. Dext, AutoEntry) linked to software | ✅ Yes | Provided the data flows digitally into the main record-keeping system |
| Spreadsheet submitted manually (re-keyed into HMRC portal) | ❌ No | Manual re-keying breaks the digital link requirement |
| Paper ledgers or cash books | ❌ No | Paper is not a digital record regardless of accuracy |
| Photos of receipts stored in a phone gallery or folder | ❌ No | Images alone are not digital records; data must be extracted and entered |
| Typed-up paper records entered weekly/monthly | ❌ No | Must be entered digitally at or near point of transaction |
| Cut and paste between spreadsheets or systems | ✅ Yes | HMRC explicitly confirms cut and paste constitutes a digital link |
The Spreadsheet Question: A Common Grey Area
Spreadsheets remain a popular record-keeping tool, especially among sole traders and smaller landlords. HMRC has confirmed that spreadsheets are acceptable under MTD — but only when used correctly.
A landlord records rental income and expenses in an Excel spreadsheet. The spreadsheet is connected to HMRC-approved bridging software via an automated data export (or even a copy-and-paste operation). The bridging software then submits the quarterly update to HMRC. This is fully compliant — provided the data in the spreadsheet meets the minimum field requirements and no manual re-keying occurs between the spreadsheet and the submission tool.
A sole trader keeps a detailed Excel spreadsheet and each quarter manually types the summary totals into HMRC’s portal or into a separate submission system. Despite the spreadsheet itself being detailed and accurate, this approach is not compliant because the transfer of data is manual, not digital.
Clients who assume their existing spreadsheet will be fine without any changes need careful guidance. The spreadsheet itself may be perfectly adequate, but without a compliant bridging solution and a genuine digital link, it does not meet MTD requirements. This is one of the most common misconceptions that accountants must proactively address.
Income and Expense Categories: Getting the Classification Right
A digital record is only as useful as the categories applied to it. HMRC requires that income and expenses are recorded under specific headings that align with the Self Assessment categories used for quarterly submissions. For self-employed individuals, these broadly follow the standard self-employment pages and include categories such as:
Income
Turnover / gross receipts from the trade or profession
Allowable Expenses
Materials, subcontractors, wages, premises, travel, advertising, and more
Capital Items
Separate treatment for assets eligible for capital allowances
Incorrect categorisation — for instance, recording a capital purchase as a revenue expense — creates errors in the quarterly submission even if the underlying transaction is digitally recorded correctly. This is why the bookkeeping function, whether performed by the client or by you, is critical to MTD compliance, not just the technology.
Offering periodic categorisation reviews — particularly at the start of each quarterly period — is a natural and billable addition to any MTD service package. It protects your clients from errors and positions you as an essential part of their financial workflow rather than a year-end afterthought.
What HMRC Does NOT Require in a Digital Record
It is equally important to understand the limits of HMRC’s requirements. Clients — and sometimes advisers — can over-engineer their record-keeping systems in pursuit of compliance. HMRC’s digital record requirements do not mandate:
- Scanned copies of receipts or invoices — the underlying source document does not need to be stored digitally (though it must still be retained in some form for at least 5 years)
- Supplier names or customer details — these are not required data fields within the digital record itself
- Invoice numbers or reference codes — again, not a mandated data field
- Real-time recording — records must be entered digitally, but HMRC does not require them to be captured at the precise moment of transaction; reasonable promptness is expected
- A single software solution — multiple tools can be used provided digital links exist between them
Practical Takeaway: The minimum compliant digital record for a self-employed individual is: the date, category, and amount of each transaction, held in a system with a digital link to an MTD-compatible submission tool. Everything beyond this is best practice, not a legal requirement — though best practice is always worth pursuing.
Property Income: Additional Considerations
Landlords face a slightly different record-keeping landscape. Where a landlord has multiple properties, HMRC currently allows records to be kept at a portfolio level rather than property by property — meaning total income and expenses across all properties can be recorded together rather than separately for each address. However, landlords should be aware this position may evolve, and keeping property-level records from the outset is advisable.
A landlord receives both rental income (from a residential property) and self-employment income (as a freelance consultant). Both income streams must be tracked under MTD separately and submitted as separate income sources within the quarterly update. Two distinct sets of digital records are required — one for the property business and one for the self-employment — even if both are held within the same accounting software.
How to Communicate This to Clients
Most clients do not need — or want — a technical walkthrough of HMRC’s legislation. What they need is clarity on what they personally must do differently. The following framing works well in client conversations:
✓ Keep It Practical
Rather than explaining what a “digital link” is in abstract terms, explain the practical reality: “Every time you receive money or spend money in your business, that transaction needs to go into your accounting software — either by your bank automatically sending it there, or by you entering it directly. What you can’t do is write it down on paper and type it up later.”
✓ Focus on What Changes for Them
For clients already using cloud accounting software and keeping records reasonably well, MTD may require very little behavioural change — primarily just more timely entry of transactions and awareness of quarterly deadlines. For those still using paper or ad hoc spreadsheets, the change is more significant, and early preparation is essential.
✓ Address the Receipt Question Head-On
Clients often ask: “Do I need to scan everything?” The honest answer is no — HMRC does not require digital copies of source documents as part of the digital record. However, those documents must still be retained and accessible. Receipt-capture apps like Dext or AutoEntry are highly useful tools, but they are not a compliance requirement in themselves.
Common Mistakes to Avoid
Clients using basic bookkeeping software or simple spreadsheets often assume they are already MTD-ready. In many cases they are not — particularly if no bridging solution is in place or if records are not being kept on a timely basis. Every client should have their current setup explicitly reviewed against the requirements, not assumed to be fine.
A client who has moved to digital invoicing and stores PDFs on their computer has not necessarily created compliant digital records. The transaction data must be in a system with digital links to an MTD-compatible submission tool — not simply in a folder of documents.
HMRC expects records to be updated on an ongoing basis — not reconstructed from memory or bank statements at the end of a quarter. Clients who batch-enter all their transactions in the days before a quarterly deadline are technically at risk, even if the records are ultimately accurate.
A compliant, well-prepared client is one who uses MTD-compatible software, has bank feeds set up so transactions import automatically, categorises those transactions at least monthly (ideally more frequently), and reviews their records with you ahead of each quarterly submission. This is not a high bar — but it does require a change of habits for many sole traders and landlords who have historically treated their finances as a once-a-year task.
Your Compliance Checklist: Is a Client’s Setup MTD-Ready?
| Check | Question to Ask | Action if No |
|---|---|---|
| Software | Is the client using MTD-compatible software or bridging-linked spreadsheets? | Migrate to compatible software or set up a bridging solution |
| Data Fields | Are date, category, and amount being recorded for every transaction? | Review record-keeping habits and provide a simple template or training |
| Digital Links | If multiple systems are used, is data transferred digitally (not retyped)? | Set up API connections, automated exports, or confirm cut-and-paste processes |
| Timeliness | Are records being updated at least monthly, not just at year-end? | Agree a schedule with the client; consider taking on bookkeeping as a service |
| Categories | Are income and expense categories aligned to HMRC’s required headings? | Review chart of accounts in the software; reclassify where needed |
| Separate Income Sources | If the client has both property and self-employment income, are these tracked separately? | Set up separate income streams or entities within the software |
