HMRC Alternative Evidence for Invoices: What You Need to Know

As a business owner or self-employed individual, keeping accurate financial records is crucial for tax compliance. However, there may be times when an invoice goes missing, or you never received one in the first place. Fortunately, HMRC allows for alternative evidence to support your tax deductions and business expenses. Here’s what you need to know about acceptable substitutes and best practices to stay compliant.

Why Do You Need Alternative Evidence?

HMRC requires businesses to maintain clear and accurate records to support all expense claims. If an invoice is unavailable due to loss, supplier issues, or other unforeseen circumstances, alternative evidence can be used to justify the expense. The key is to ensure that the alternative documentation provides sufficient detail to verify the transaction.

What Counts as Alternative Evidence?

If an invoice is missing, you can present the following types of evidence as a substitute:

✅ Bank Statements – A clear record showing the payment made to the supplier, including the date and reference details.

✅ Receipts or Order Confirmations – If you made an online purchase, an email confirmation or digital receipt can serve as proof of the transaction.

✅ Emails or Written Agreements – Correspondence with the supplier detailing the goods or services purchased, the agreed price, and payment terms.

✅ Delivery Notes – Proof that goods were received and accepted, especially useful when combined with other evidence.

✅ Credit Card Statements – These can help verify payments made for business expenses, particularly when matched with other supporting documents.

✅ Cancelled Cheques – If you paid by cheque, a copy of the cancelled cheque showing that the payment was processed can be useful.

✅ Photographs or Screenshots – In some cases, images of goods received or screenshots of digital transactions can support a claim.

Best Practices for Compliance

To avoid issues with HMRC and ensure smooth tax filing, consider the following best practices:

🔹 Keep Digital Copies – Scan and store all receipts, order confirmations, and important documents in a secure cloud-based system.

🔹 Match Payments with Documentation – Cross-reference bank transactions with invoices or other supporting documents.

🔹 Request Duplicates from Suppliers – If possible, contact suppliers for a duplicate invoice to ensure complete records.

🔹 Use Accounting Software – Platforms like Xero, QuickBooks, or FreeAgent can help you track expenses and generate reports if documents go missing.

🔹 Maintain Clear Notes – If relying on alternative evidence, make notes explaining the transaction details, including the reason for the missing invoice.

Will HMRC Accept Alternative Evidence?

HMRC recognises that invoices can sometimes be unavailable and will typically accept reasonable alternative evidence, provided it is clear, accurate, and legitimate. However, having multiple forms of evidence is always advisable to strengthen your case.

If you are ever in doubt about whether your documentation is sufficient, consulting an accountant or tax professional can help ensure you remain compliant.

Final Thoughts

Losing an invoice doesn’t mean you lose a tax deduction! By keeping thorough records and knowing what alternative evidence is acceptable, you can ensure that your business remains compliant while maximising allowable expenses. Stay organised and proactive in record-keeping to avoid any HMRC challenges in the future.
