Receipt Management Best Practices
What Receipts Do You Need?
Keep receipts for all business expenses, no matter how small. Every receipt should include:
- Date of purchase
- Supplier name and address
- Description of goods/services
- Amount paid
- VAT details (if applicable)
Digital vs Paper Receipts
HMRC fully accepts digital receipts, making them perfect for modern freelancers. Digital receipts offer several advantages:
- No risk of fading or losing paper receipts
- Easy to organise and search
- Automatic backup and security
- Integration with accounting software
- Environmentally friendly
Record Keeping Requirements
How Long to Keep Records
HMRC requires you to keep business records for:
- 5 years from 31 January following the end of the tax year
- 6 years if you're VAT registered
- Permanently for some records like contracts and insurance policies
What Records to Keep
- All business receipts and invoices
- Bank statements showing business transactions
- Records of business income
- Mileage records for business travel
- Inventory records (if applicable)
- Annual accounts and tax returns
Common Self Assessment Mistakes to Avoid
1. Missing the Deadline
Late filing penalties start at £100 and increase significantly. Set reminders well in advance and consider submitting early.
2. Poor Record Keeping
Inadequate records can lead to rejected expense claims and potential investigations. Maintain organised, comprehensive records throughout the year.
3. Mixing Personal and Business Expenses
Keep business and personal expenses completely separate. Use a dedicated business bank account and credit card.
4. Claiming Non-Allowable Expenses
Common non-allowable expenses include:
- Personal travel and entertainment
- Fines and penalties
- Personal insurance and medical expenses
- Personal clothing (unless it's a uniform or protective wear)

VAT Considerations for Freelancers
VAT Registration Threshold
You must register for VAT if your taxable turnover exceeds £90,000 in any 12-month period (as of 2025).
