HMRC-Compliant Receipt Capture: What Every Accountant Needs to Know
Making Tax Digital (MTD) has fundamentally changed the landscape of tax compliance in the United Kingdom. Since April 2019 for VAT and with the upcoming rollout for Income Tax Self Assessment (ITSA) from April 2026, HMRC requires businesses to maintain digital records and submit returns using MTD-compatible software.
For accountants and their clients, this creates both challenges and opportunities. How exactly does MTD affect receipt capture? What pitfalls lurk in the digitisation process? And how can accountants efficiently guide their clients towards compliance? This guide provides answers.
What Is Making Tax Digital? The Basics Explained
Making Tax Digital is HMRC's initiative to transform tax administration through digital technology. The legal basis comes from the Finance (No. 2) Act 2017 and subsequent regulations. MTD requires businesses to:
- Keep digital records of all transactions
- Use compatible software to maintain those records
- Submit returns digitally through the software
Core Principles of MTD Recordkeeping
| Principle | Requirement | Practical Relevance |
|---|---|---|
| Digital Records | All tax-relevant transactions must be recorded digitally | No manual spreadsheets or paper-only systems |
| Accuracy | Records must be correct and complete | Regular reconciliation required |
| Timeliness | Records must be kept up to date | Quarterly updates for ITSA |
| Preservation | Records must be kept for minimum periods | 6 years for most business records |
| Accessibility | HMRC must be able to access records on request | Software must support data extraction |
| Audit Trail | All changes must be traceable | Who changed what and when? |
Who Must Comply with MTD?
The scope of MTD has been expanding progressively:
- MTD for VAT (since April 2019): All VAT-registered businesses must keep digital VAT records and submit VAT returns through MTD-compatible software
- MTD for ITSA (from April 2026): Self-employed individuals and landlords with annual business or property income above £50,000 must comply. The threshold drops to £30,000 from April 2027
- MTD for Corporation Tax: Expected in the future, though no firm date has been set
- Purchase and sales invoices
- Receipts and till records
- Travel expense claims and entertainment receipts
- Contracts with tax implications
- Bank statements and payment records
- Emails constituting business correspondence
Digital Receipt Capture: What HMRC Specifically Requires
1. Timely Recording
A common mistake: many businesses let receipts pile up for weeks before digitising them. HMRC expects records to be maintained on a regular and timely basis. Best practice guidelines:
- Till receipts: Daily recording, especially with point-of-sale systems
- Purchase invoices: Within a few days of receipt
- Travel expense receipts: Promptly after the trip, ideally at the point of purchase
Practical tip for accountants: clients should photograph receipts immediately upon receiving them. Modern apps like Bill.Dock make this possible directly from a smartphone, with automatic text recognition (OCR) that extracts all key data.
2. Quality Requirements for Digital Copies
HMRC accepts digital copies of paper receipts, but with conditions:
Requirements for scan quality:- Legibility: All information on the original must be clearly readable in the digital copy
- Completeness: The full receipt must be captured, including any handwritten notes
- Format: HMRC accepts common formats including PDF, JPEG, and PNG
- Standard paper receipts and till records
- Printed invoices
- Legal documents and contracts
- Import/customs documentation
- Any document where the original format has specific legal significance
3. Digital Records: The Functional Compatible Software Requirement
MTD requires the use of functional compatible software that can:
- Record and store digital records: All transactions must be captured digitally
- Provide information to HMRC: Software must connect to HMRC's APIs
- Receive information from HMRC: Including acknowledgements and error messages
- Digital links: Where multiple software products are used, data must flow digitally between them (no manual re-keying)
Important: Using spreadsheets alone is not compliant. If spreadsheets are part of the workflow, they must be digitally linked to bridging software that connects to HMRC.
4. Record Retention Requirements
| Requirement | Detail |
|---|---|
| Minimum Retention | Business records must be kept for at least 6 years |
| VAT Records | Must be kept for 6 years (or 10 years for certain transactions) |
| CIS Records | Construction Industry Scheme records for 3 years after the tax year |
| Capital Assets | Records relating to capital items may need to be kept longer |
| Digital Format | Records kept digitally must remain accessible and readable |
| Backup | Regular backups are strongly recommended |
The Most Common MTD Compliance Mistakes
Based on HMRC enquiries and practice experience, these are the most frequent errors:
Mistake 1: Using Non-Compatible Software
Some businesses still rely on basic spreadsheets or legacy systems that don't meet MTD requirements. HMRC can issue penalties of up to £400 per failure for not using compatible software.
Solution: Ensure clients use HMRC-recognised MTD-compatible software. Bill.Dock connects directly with leading UK accounting packages and supports MTD-compliant record keeping.Mistake 2: Breaking Digital Links
When data is manually re-keyed between systems rather than transferred digitally, this breaks the "digital link" requirement. HMRC has been enforcing this strictly since April 2021.
Mistake 3: Incomplete Record Keeping
Failing to capture all relevant receipts and invoices, or keeping them in a disorganised manner that makes retrieval difficult during an HMRC enquiry.
Mistake 4: Not Retaining Original Digital Invoices
When an invoice is received electronically (e.g., by email), the electronic version is the original. Printing it out and scanning it back is not the same as retaining the original digital document.
Mistake 5: Ignoring the Quarterly Submission Requirement
Under MTD for ITSA, quarterly updates must be submitted within one month of the end of each quarter. Missing these deadlines results in late filing penalties.

HMRC Enquiries: How Accountants Should Prepare Their Clients
Types of HMRC Enquiry
HMRC can open enquiries into any tax return:
- Full enquiry: A comprehensive review of all aspects of the return
- Aspect enquiry: Focused on specific items or discrepancies
- Random enquiry: Selected without specific reason as part of HMRC's compliance programme
HMRC Enquiry Preparation Checklist
Before an enquiry:- All digital records are current and complete
- Software and system versions are documented
- Access credentials are prepared for read-only review
- Data backup completed before the enquiry begins
- Test export to ensure data is accessible
- Only provide what is specifically requested
- Document all HMRC requests
- Do not make corrections during an active enquiry without discussion
Travel and Entertainment Expenses: Special HMRC Requirements
Travel and entertainment expenses are a frequent focus of HMRC enquiries:
Business Entertainment
Under HMRC rules, business entertainment is generally not deductible for tax purposes (ITTOIA 2005, s.45). However, detailed records must still be maintained:
- Name and address of the venue
- Date of the event
- Business purpose
- Names of attendees and their business relationship
- Itemised costs
Mileage Allowances (2026)
- HMRC Approved Mileage Rates: 45p per mile for the first 10,000 miles, 25p thereafter
- Mileage log: Must be kept contemporaneously; reconstructed logs are not accepted
- Digital mileage tracking: Accepted if the software meets record-keeping requirements
Per Diem and Subsistence
| Duration | Benchmark Rate (2026) |
|---|---|
| 5+ hours | £5.00 |
| 10+ hours | £10.00 |
| 15+ hours (or overnight) | £25.00 |
| Staying away overnight | £25.00 (plus actual accommodation) |
HMRC requires evidence of business travel to support subsistence claims — boarding passes, hotel invoices, or other documentation.
Client Advisory: Communicating MTD Requirements Effectively
The Most Common Client Questions
Can I throw away paper receipts after scanning them?Yes, provided the digital copy is legible and stored in compliant software. However, keeping originals for high-value or unusual transactions is recommended.
Is a phone photo good enough as a receipt?Yes, if it's legible and promptly uploaded to MTD-compatible software. A photo sitting in your camera roll does not meet the requirements.
Can I store receipts in iCloud or Google Drive?Not on its own — generic cloud storage doesn't meet MTD's functional compatible software requirements. Receipts must be in software that can submit to HMRC.
What are the penalties for non-compliance?Penalties under the new points-based system include late submission penalties (points leading to £200 penalties), late payment penalties (up to 4% of outstanding tax), and interest on late payments.
Client Compliance Checklist
Accountants can share this checklist with their clients:
Daily tasks:- Photograph receipts immediately upon receiving them
- Forward email invoices to your archiving system
- Record any cash transactions
- Digitise any accumulated paper receipts
- Check completeness of recorded transactions
- Reconcile bank transactions with receipts
- Submit MTD quarterly update (for ITSA)
- Review and clean up any uncategorised transactions
- Verify backup integrity
MTD and Data Protection: Balancing Compliance
A frequently overlooked issue: MTD and UK GDPR create competing obligations.
The tension:- MTD requires keeping business records for at least 6 years
- UK GDPR requires data minimisation and the right to erasure
Legal obligations for record retention override the right to erasure (UK GDPR, Article 17(3)(b)). Personal data in business records may be retained for the statutory period.
Practical note: Your archiving system should distinguish between tax-relevant and non-tax-relevant personal data. Bill.Dock supports automatic deletion workflows after retention periods expire.Conclusion: MTD-Compliant Receipt Capture as a Competitive Advantage for Accountants
Making Tax Digital is not just a compliance burden — it's an opportunity. Practices that proactively guide their clients through digital receipt capture create genuine value and build lasting client relationships.
Key takeaways:- Timely capture is essential — receipts should be digitised at the point of transaction
- Functional compatible software is mandatory — basic spreadsheets alone won't do
- Digital links must be maintained — no manual re-keying between systems
- Retention periods matter — keep records for at least 6 years
- Quarterly updates are coming — prepare clients for MTD for ITSA from April 2026

Frequently Asked Questions (FAQ)
What does MTD-compliant mean?
MTD-compliant means that your record-keeping and filing processes meet HMRC's Making Tax Digital requirements: digital records, compatible software, and digital submission of returns.
Can I destroy paper receipts after scanning them?
Yes, provided the digital copy is legible, complete, and stored in functional compatible software. Some documents with specific legal significance should be kept in their original form.
How long must I keep business records?
Business records must generally be kept for 6 years from the end of the relevant tax year. VAT records may need to be kept for up to 10 years in some cases.
Is an app like Bill.Dock MTD-compatible?
Bill.Dock meets the technical requirements for MTD-compatible record keeping: tamper-proof archive, full audit trail, and integration with HMRC-recognised accounting software. However, using compliant software does not remove the need for proper record-keeping processes.
What happens if I'm not MTD-compliant?
HMRC can impose penalties under the points-based penalty system. Repeated failures to submit on time or keep adequate records can result in financial penalties, interest charges, and potentially more serious consequences.
Do I need to keep email invoices?
Yes. If invoices are received electronically, the electronic version is the original document and must be retained in digital form for the required retention period.
What is the digital links requirement?
Digital links means that where data is transferred between software products, it must flow digitally without manual re-keying. Copy-pasting between spreadsheets, for example, breaks this requirement.
