How to Keep Track of Business Receipts and Expenses

Keeping accurate track of your business receipts and expenses isn’t just an accounting chore—it’s the foundation for legal compliance, tax savings, and understanding your company’s true performance. For UK small business owners, getting this right means you avoid HMRC penalties, claim every allowable expense, and make better decisions. This guide cuts through the confusion, showing you exactly what to keep, how to organise it, and which tools work best for UK businesses.

Every UK business—whether a sole trader, partnership, or limited company—is legally required to keep accurate records of income and business expenses. HMRC expects you to retain supporting evidence for your accounts and tax returns, such as receipts, invoices, and bank statements. If you’re ever subject to an HMRC investigation or compliance check, your records are your first line of defence. Inadequate record keeping is one of the most common reasons for penalties and additional tax assessments.

Beyond compliance, keeping track of receipts and expenses is crucial for your financial health. It allows you to monitor cash flow, spot unnecessary spending, and identify tax-deductible costs you might otherwise miss. Good records also make it easier to apply for loans, manage VAT, and create accurate financial statements if you seek investment or want to sell your business.

The UK government has made digital record keeping even more important with the introduction of Making Tax Digital (MTD). Most VAT-registered businesses must now keep digital records and submit VAT returns via MTD-compatible software. In the coming years, MTD will extend to Income Tax Self Assessment, making digital receipt and expense management essential for nearly all small businesses.

A business receipt is any document that proves you’ve spent money on a business-related cost. This includes traditional till receipts, supplier invoices, digital receipts from online purchases, and even parking or travel tickets. An expense is any cost you incur wholly and exclusively for your business activities. HMRC is very clear: you can only claim expenses that are genuinely for business, not personal use.

Common receipts you’ll need to keep include those for office supplies, rent, software subscriptions, travel, equipment, marketing, and professional fees. For some expenses, such as motoring or working-from-home costs, you may need to keep additional records like mileage logs or utility bills. If you import goods, customs documentation and VAT certificates are also critical.

It’s a common mistake to think that a bank statement alone is enough. HMRC expects to see the original receipt or invoice, not just evidence that money left your account. Digital copies are acceptable, but they must be clear and complete.

• Supplier invoices (for goods and services purchased)
• Retail till receipts (for everyday purchases)
• Digital receipts from online transactions
• Mileage logs (for business travel in your own vehicle)
• Utility bills (for business premises or home office)
• Bank statements (to cross-check with receipts, not as sole evidence)

The retention period for business receipts and expense records depends on your business structure. For sole traders and partnerships, HMRC requires you to keep records for at least five years after the 31 January submission deadline of the relevant tax year. For limited companies, the Companies Act 2006 requires you to keep records for at least six years from the end of the financial year they relate to, or longer if they show a transaction that covers more than one accounting period.

In practice, many accountants recommend keeping records for seven years to cover any potential HMRC inquiries, which can be opened several years after a return is filed. If you’re VAT registered, VAT records must be kept for at least six years. If you have employees, payroll records must be kept for at least three years.

Failing to keep adequate records can result in penalties of up to £3,000 from HMRC, plus the risk of additional tax assessments if you can’t prove your expenses. The records can be kept as originals, photocopies, or digital scans—as long as they’re clear, complete, and easily accessible.

You can keep receipts and expense records in paper or digital form, but digital storage is now the practical standard for UK businesses. HMRC accepts digital copies, provided they’re complete, legible, and accessible. In fact, under Making Tax Digital, digital record keeping is compulsory for VAT-registered businesses—and will soon be for most self-employed people.

Digital storage offers several advantages. It reduces physical clutter, protects against loss or damage, makes searching and retrieval much faster, and integrates seamlessly with accounting software. Scanning or photographing receipts as soon as you receive them is best practice. There’s no need to retain the original paper once you have a clear digital copy (unless the document is required for legal reasons, such as some property or company formation records).

If you still use paper records, use clearly labelled envelopes or folders for each month or expense category, and store them somewhere safe from fire, damp, or theft. However, be aware that faded, damaged, or lost paper receipts are not accepted as valid evidence by HMRC. Backups and clear filing systems are critical, whichever method you choose.

• Scan or photograph receipts on your phone as soon as you get them
• Organise digital files by year and expense category for easy retrieval
• Use cloud storage (OneDrive, Google Drive, Dropbox) to keep files safe and accessible
• Regularly back up your records to a separate location
• Shred sensitive paper records once digitised (unless originals are required)

There’s a huge range of tools available to help UK small businesses manage receipts and expenses. At a minimum, you’ll need a way to capture receipts (scanning app or smartphone), a system to organise digital files, and a method for recording and categorising expenses—ideally integrated with your bookkeeping or accounting software.

Many UK businesses now use cloud accounting software such as Xero, QuickBooks, Sage Business Cloud Accounting, or FreeAgent. These platforms allow you to upload, categorise, and attach receipts directly to transactions. They also provide MTD-compliant VAT filing, automate expense claims, and make it easy to generate reports for your accountant or HMRC.

If you’re not ready for full accounting software, there are excellent receipt-scanning apps (such as Receipt Bank, now Dext, and Expensify) that integrate with spreadsheets or simple bookkeeping tools. Make sure any tool you choose is compatible with MTD if you’re VAT registered, and that it keeps your data secure and regularly backed up.

Always check that your chosen solution is up to date with HMRC requirements, especially as MTD expands. If you work with an accountant, ask for their recommendation—they may provide discounted access or prefer software that integrates directly with their systems.

To avoid missed expenses, lost receipts, and year-end panic, you need a clear process for capturing, recording, and reconciling every business expense. This isn’t just about storing receipts—it’s about ensuring your accounting records match your bank statements and that every allowable expense is claimed. For most UK small businesses, doing this weekly or monthly is best practice.

The process starts the moment you incur an expense. As soon as you pay for something (with cash, card, or online), capture the receipt—scan or photograph it, and upload it to your chosen system. Then enter the expense into your accounting software or spreadsheet, categorising it correctly (e.g. travel, office supplies, marketing). Regularly reconcile these records with your business bank statement to ensure nothing is missed or duplicated.

If you pay for business expenses personally, make sure to record them as reimbursable and keep the supporting receipts. If you have employees, set a clear expenses policy and require receipts for all claims. At the end of each month or quarter, review your records, chase up missing receipts, and prepare for VAT or tax filing.

• Set calendar reminders for weekly or monthly expense reviews
• Train staff to submit receipts promptly (if you have employees)
• Use smartphone apps to capture receipts on the go
• Always check receipts for VAT details if you intend to reclaim VAT
• Record all cash expenses—these are often missed at year-end

Many UK small business owners fall into traps that lead to missed expenses, HMRC challenges, or unnecessary admin headaches. The most frequent mistake is thinking that bank statements alone are enough evidence—they aren’t. HMRC expects the actual receipt or invoice showing what was purchased, who supplied it, and when.

Another common pitfall is mixing personal and business expenses, especially for sole traders. Always use a dedicated business bank account and card for all business transactions. This makes record keeping far simpler and provides a clear audit trail if HMRC investigates.

Don’t assume all business spending is tax-deductible. HMRC’s 'wholly and exclusively' rule is strict. If an expense has a dual purpose (business and personal), only the business proportion can be claimed. This often catches out home office, vehicle, and phone expenses. You must be able to justify the split with clear records (such as a mileage log or itemised bill).

• Never claim expenses without a valid receipt or invoice
• Don’t rely on bank statements as your sole evidence
• Avoid paying business costs from personal accounts
• Always separate business and personal spending
• Don’t claim VAT on non-VAT invoices or receipts
• Keep mileage logs for all business journeys

If your business is VAT registered, you must keep additional records to satisfy HMRC. You need valid VAT invoices for all purchases where you reclaim VAT, and your accounting software must be MTD-compatible. Every VAT return must be based on digital records—not handwritten notes or spreadsheets.

A valid VAT receipt must show the supplier’s name and address, their VAT registration number, the date, a description of the goods or services, the total amount, and the VAT charged. For purchases under £250 (including VAT), a simplified VAT invoice is acceptable. You must keep these for at least six years, and they must be accessible electronically if HMRC requests them.

If you use the Flat Rate VAT Scheme, you still need to keep all your receipts and invoices as evidence for HMRC, even though you may not reclaim VAT on most purchases. Under MTD, all VAT-registered businesses (above the £85,000 turnover threshold, and from April 2022, all VAT-registered businesses) must keep digital records and use MTD-compatible software.

Not using compatible software or failing to keep digital records can lead to penalties, rejected VAT returns, and additional scrutiny. Review your current systems—if you’re not already digital, now is the time to switch.

Modern businesses increasingly receive receipts via email or from online platforms. HMRC accepts digital receipts, but you must be able to produce them on request. Save emailed receipts as PDFs, and upload them to your cloud storage or accounting software. For recurring online purchases (like software subscriptions), create a folder for each supplier and save each invoice as it arrives.

Foreign currency receipts (for overseas travel or purchases) must be converted to sterling for your accounts. Use the HMRC-approved exchange rate for the date of the transaction. Keep the original foreign receipt, plus a record of the sterling amount used in your books. For PayPal or card payments, download the transaction report to support the conversion.

Lost receipts are a perennial problem. If you lose a receipt, try to obtain a duplicate from the supplier or use alternative evidence (such as a booking confirmation or credit card statement). For small cash expenses, keep a logbook and note the date, amount, and purpose. HMRC may allow claims for reasonable, clearly business-related costs if you can show a consistent, honest approach—but they are under no obligation to do so.

• Save email receipts as PDFs and upload to your record system
• For online purchases, download and file invoices immediately
• Convert foreign receipts to GBP using HMRC exchange rates
• For recurring subscriptions, set up automated folder rules
• Keep a logbook for small cash-only expenses

Good receipt and expense management doesn’t just keep HMRC happy—it drastically reduces your accountancy costs and the risk of errors. Accountants often spend hours chasing missing receipts, untangling personal and business transactions, or fixing mistakes from poorly kept records. The more organised you are, the less time they need to spend—saving you money and ensuring accurate accounts.

When handing over your records, ensure everything is categorised, legible, and complete. Provide digital access to your cloud storage, accounting software, or shared folders. Include clear explanations for unusual or high-value expenses, and provide supporting contracts or agreements if relevant (for example, for asset purchases or consultancy fees).

If you use software, give your accountant their own login. Avoid the temptation to dump a box of mixed receipts at year-end—this leads to missed expenses, higher fees, and a longer wait for your accounts or tax return. A little admin each week saves a huge headache (and unnecessary costs) later.

• Keep receipts and expenses up to date—don’t leave everything to year-end
• Use consistent categories and descriptions
• Provide digital access to your accountant
• Flag any unusual or large transactions with an explanation
• Ask your accountant for feedback on your record keeping

If you’ve fallen behind or are starting a new business and have no system yet, don’t panic—but act quickly. Gather all available receipts, invoices, and bank statements. Download digital records from suppliers, email inboxes, and online portals. Sort everything by month and category, and log missing items for follow-up.

For missing receipts, try to obtain duplicates from suppliers or use alternative evidence (such as order confirmations, shipping records, or bank statements). Be honest with your accountant or bookkeeper about any gaps—they can advise how to make reasonable estimates or disclosures to HMRC if needed.

Once you’re caught up, implement a simple, repeatable process going forward. Even a basic system (weekly receipt scans, spreadsheet updates, and regular backups) is far better than nothing. The earlier you start, the less stressful and expensive it is to stay compliant.

• Collect all paper and digital receipts from the past year(s)
• Download bank and credit card statements for cross-checking
• Contact suppliers for duplicate invoices where needed
• Log expenses you remember but lack receipts for, and seek evidence
• Start a new digital system immediately to avoid future issues
