Good record keeping is one of the most important parts of running a business. It is not just about staying organised — it directly affects how much tax you pay, how smooth your tax return process is, and how confident you feel if HMRC ever asks questions.
Why record keeping matters
Accurate records allow you to:
- Prepare correct tax returns
- Claim all allowable expenses
- Avoid overpaying tax
- Respond quickly to HMRC queries
- Stay compliant with Making Tax Digital (MTD)
Poor record keeping often leads to missed expenses, incorrect figures, and unnecessary stress.
What records you should keep
At a minimum, you should keep:
1. Sales records (income)
- Invoices issued to customers
- Till receipts or EPOS reports
- Bank statements showing income received
2. Purchase records (expenses)
- Supplier invoices
- Receipts for business purchases
- Mileage logs (if claiming travel)
3. Bank and financial records
- Business bank statements
- Credit card statements
- Loan agreements
4. Payroll records (if applicable)
- Payslips
- Pension contributions
- PAYE records
5. VAT records (if registered)
- VAT invoices
- VAT returns
- Digital records (for MTD compliance)
Invoices and receipts – the key evidence
Invoices and receipts are the foundation of your accounts.
- Invoices prove income earned
- Receipts prove expenses incurred
Without these, there is no evidence to support your figures.
What happens if you don’t have records?
If you cannot provide evidence for a transaction:
- HMRC can disallow the expense
- Your tax bill may increase
- You may face penalties or interest
- In serious cases, HMRC may open an enquiry
Put simply:
👉 No receipt = no expense claim
Even if the cost is genuine, HMRC can refuse it if it cannot be supported.
How long should you keep records?
In most cases:
- Sole traders: at least 5 years after the 31 January submission deadline
- Limited companies: at least 6 years
Digital record keeping and MTD
With Making Tax Digital becoming more common, keeping digital records is no longer optional for many businesses.
Using software such as Xero or similar:
- Reduces errors
- Keeps everything in one place
- Allows real-time tracking of income and expenses
- Makes quarterly submissions easier
Simple tips to stay organised
- Keep business and personal spending separate
- Upload receipts as you go (don’t leave it until year end)
- Use accounting software where possible
- Keep a consistent filing system (digital or physical)
- Review your records monthly
Final thought
Good record keeping is not just admin — it is part of managing your finances properly. It saves time, reduces tax risk, and gives you a clear picture of how your business is performing.
If your records are clean and up to date, your tax return becomes a straightforward process rather than a last-minute scramble.
