How to Ensure Your Expense Receipts are HMRC Compliant

By Ashley FerroApril 25, 2024

Managing your business’s expense receipts can be a headache, but it doesn't have to be.  

Making sure your receipts are HMRC compliant is essential to avoid penalties and maximise your tax deductions. From understanding what makes a receipt valid to simplifying audits and optimising storage, this comprehensive guide has you covered.  

What Qualifies as a Valid Expense Receipt? 

What Qualifies as a Valid Expense ReceiptTo qualify as a valid expense receipt for business claims, every receipt must include the following information: 

  1. Date of transaction: It's important that the receipt shows when the purchase was made. This date helps to match the expense with the right financial period. 

  2. Vendor details: The receipt should have the name and contact info of the vendor. This information confirms the receipt's legitimacy and is useful if you need to reference the transaction later. 

  3. Amount paid: Clearly stated on the receipt should be the total amount paid, along with an itemised list of costs if needed (like taxes and discounts). 

  4. Payment method: How was the payment made - cash, credit card, or another method? This detail is important for tracking and verifying the transaction. 

  5. Description of goods or services: What exactly was bought or what service was provided? The receipt should list these details, including quantities and prices, which helps justify the expense for business purposes. 

  6. Business purpose: Not always listed directly on the receipt but important to note alongside it is the business reason for the expense. This is crucial for tax purposes. 

For receipts to support your business expense claims effectively, they must be complete and clear. Proper documentation not only helps with compliance but also with efficient financial tracking and easier audits. 

Why are Expense Receipts Important for Business Tax Deductions? 

Expense receipts are crucial for managing your business's finances effectively and ensuring you stay compliant with tax regulations.  

Why are Expense Receipts Important for Business Tax DeductionsHere's a deeper look into why they’re so important: 

1. Securing Tax Deductions 

For UK employers, keeping accurate and detailed expense receipts is essential. These receipts prove that your expenses were genuinely for business purposes, allowing you to claim tax deductions accurately.  

Without them, you could miss out on important deductions and end up paying more tax than necessary.  

2. Complying with Tax Laws 

Properly maintained expense receipts ensure your business meets tax laws. These receipts are critical during audits, as they help verify that your expense claims are accurate and justified.  

By maintaining clear and accurate receipts, you can avoid penalties for non-compliance, ensuring your business doesn't face unnecessary fines. 

3. Simplifying Audit Processes 

Having organised and valid expense receipts can streamline the audit process.  

Auditors can quickly verify your financial transactions, ensuring that your business maintains transparent and compliant accounting practices. 

4. Improving Budget Management 

Properly managing expense receipts is essential not just for staying compliant with tax laws, but also for improving your overall financial management.  

Keeping detailed receipts helps you track and manage your spending accurately, which is crucial for planning your budget and making smart financial decisions.

This level of organisation lets you see where your money is going, helps you allocate resources more effectively, and plan your expenses more strategically.  

Ultimately, this can lead to smoother business operations and a more stable financial future for your company. 

How Should Businesses Store Expense Receipts? 

Storing expense receipts properly is essential for any UK business aiming to stay compliant with tax laws and ensure financial accuracy.  

How to Store Physical and Digital Expense ReceiptsHere’s how businesses can effectively store both physical and digital receipts: 

How to Store Physical Expense Receipts 

For physical receipts, it's important to use a systematic approach: 

  • Organise by date & category: Sort receipts by date and type of expense. This makes it easier to find specific items when needed, particularly during tax season or in the event of an audit. 

  • Use a filing system: Implement a filing system using folders or filing cabinets. Label each section clearly to avoid any confusion and ensure quick retrieval. 

  • Maintain a safe environment: Store receipts in a dry, secure place away from potential damage like water or fire. Consider using fireproof storage options to protect critical financial documents. 

To streamline and secure your process for handling physical receipts, consider digitising them 

Expense management software like ExpenseIn, which offers receipt scanning capabilities, can help. This tool not only stores your receipts digitally but also organises them efficiently. That way, you can easily access them during audits or tax season.  

Digitising your receipts reduces the need for physical storage and enhances both the security and accessibility of your financial records. 

How to Store Digital Expense Receipts 

Digital storage offers convenience and accessibility, and here are the best practices to follow: 

  • Scan or use digital receipts: Convert all physical receipts into e-receipts by scanning them. Many businesses also receive digital receipts directly via email, which can then be automatically imported into their accounting software, simplifying the management of financial records. 

  • Use cloud storage: Store digital receipts on the cloud. This not only saves physical space but also allows you to access receipts from anywhere, enhancing flexibility and security. 

  • Back-up regularly: Ensure that digital receipts are backed up regularly to prevent data loss. Use multiple backup solutions, if possible, to ensure there is always a secure copy available. 

  • Leverage expense management software: Utilise a business expense tracker app to automate the storage and organisation of digital receipts. These platforms can help categorise expenses, integrate with accounting systems, and provide detailed reports, simplifying financial tracking and analysis. 

Note: Both physical and digital receipts need to be stored for at least three years from the end of the tax year they relate to, according to HMRC guidelines 

This ensures you have the necessary documentation available in case of audits or financial reviews, providing evidence of how each expense was accounted for throughout the year. 

What are the Rules for Expense Receipts Under UK Tax Law? 

In the UK, managing expense receipts correctly is not just good practice - it's a legal requirement for employers.  

Here’s an overview of specific rules and documentation needed as per UK tax laws: 

Reporting & Paying Taxes on Expenses 

If you provide expenses or benefits to employees, you must report them to HMRC and pay any tax and National Insurance due. These might include costs like:  

It’s crucial to use your payroll system or an online submission at the end of the tax year to report these expenses. 

Types of Reporting 

  • Through payroll (‘payrolling’): Report and pay tax on employee expenses and benefits through your payroll as they occur. You won’t need to report these expenses at the tax year's end if they are fully payrolled. 

  • Through year-end forms: If not payrolled, you must submit a P11D form for each employee with non-payrolled taxable expenses or benefits. Also, report the total Class 1A National Insurance due using a P11D(b) form. 

Read our article, Should Expenses Be Paid Through Payroll (Guide), for more information on the topic.

Submission Method 


Routine employee expenses like business travel, phone bills, and uniforms don't need to be reported if they fall under HMRC's exemptions 

These expenses can either be reimbursed at a flat rate (either a benchmark rate or a bespoke rate approved by HMRC) or by repaying the actual costs. 

Record Keeping 

It’s mandatory to keep records of all expenses and benefits for at least three years from the end of the tax year they relate to. Your records should include: 

  • Date and details of every expense or benefit. 

  • Any necessary information to calculate the amounts on your end-of-year forms. 

  • Any payments contributed by employees towards their expenses or benefits. 

You should also keep any records of communication you have with HMRC. 

Can Digital Copies of Receipts Be Used for Tax Purposes? 

Yes, digital receipts are acceptable by HMRC as long as they meet certain criteria. 

Digital copies are recognised by HMRC if they are exact copies of the original receipts and include all necessary information. This means the digital version should clearly show the:  

  • Transaction date 

  • Vendor details 

  • Total amount paid 

  • Payment method 

  • Description of goods or services 

  • Business purpose of the expense 

Conditions for Using Digital Expense Receipts 

To ensure digital receipts are valid for tax purposes, you should: 

  • Ensure clarity & completeness: The digital expense receipt must be legible and include every detail found on the physical receipt. 

  • Store securely: Keep digital expense receipts in a secure place where they can't be tampered with or lost. Cloud storage is a great option because it also allows for backups. 

  • Maintain easy access: Organise your digital expense receipts well so you can quickly find them if HMRC requests them during an audit. 

To stay compliant, remember to keep digital receipts for at least three years from the end of the tax year they relate to. This is important because HMRC may ask to see them during audits. 

What Happens if You Lose an Expense Receipt? 

Losing an expense receipt isn't ideal, but it doesn't have to be a disaster for your business.

What Happens if You Lose an Expense ReceiptHere’s what you can do if a receipt goes missing: 

1. Document Lost Receipts 

First, it's important to act promptly to recreate the record of the transaction to the best of your ability. 

Immediately write down all the details you remember about the expense. Include the: 

  • Date 

  • Vendor 

  • Amount 

  • Purpose of the expense 

2. Provide Alternative Proof 

If the original receipt is gone, HMRC does accept other forms of proof. These can include: 

  • Bank or credit card statements that show the transaction. 

  • A duplicate receipt, if you can get one from the vendor. 

  • Detailed notes that log the expense. 

As mentioned in our article Business Expenses: Can I Claim Expenses Without a Receipt?, even if you don’t have the original receipts, documenting your expenses thoroughly and having other forms of verification can often suffice. Detailed notes alongside official records can substantiate your expense claims in many situations. 

3. Prevent Future Losses 

To avoid problems with lost receipts in the future, consider using digital expense management solutions like ExpenseIn.

These tools can scan and save your receipts digitally, so you have a backup and an easy way to access them when needed for taxes or audits. 

Are All Types of Expense Receipts Treated the Same? 

Not all types of expense receipts are treated equally under UK tax laws. Different types of expenses, like travel, meals, office supplies, and more, each require specific details and handling. 

Travel Expenses Receipts 

For employee travel expense receipts, you need to include important details such as:  

  • Date 

  • Location 

  • Purpose of the trip 

  • Amount spent 

It's vital to clearly state the business reason for the trip directly on the receipt or in related documentation to ensure these expenses are recognised as business-related. 

Meals & Entertainment Receipts 

Receipts for business meals should include the cost and date. Alongside the receipt, in the expense claim, you should also record the names of attendees and the business reason for the meal. 

This detail helps prove that the expense is strictly for business purposes and not personal enjoyment. 

Office Supplies & Equipment Receipts 

For office supplies, receipts should clearly itemise each purchase with dates and total costs.  

For larger items like equipment or furniture, you might also need to keep track of additional details such as serial numbers and warranty information.
