The Short Answer:
No, you do not legally have to do "bookkeeping" in the formal sense to comply with HMRC.
However, you must keep accurate records and documents.
It is a subtle but critical difference. This guide explains the difference, the risks of skipping bookkeeping, and whether you should handle it yourself.
HMRC does not legally require you to use accounting software (like Xero or QuickBooks) or maintain a double-entry ledger. Their strict legal requirement is that you keep the original records (evidence) of your trading so that an accurate tax return can be prepared.
Many new eBay traders confuse the two. To stay compliant, you need to understand the distinction.
Record Keeping
MANDATORY
This is the act of saving the evidence of your transactions.
For an eBay business, this means saving:
HMRC Rule:
You must be able to show "a complete and accurate return" based on these records.
Bookkeeping
OPTIONAL (But Recommended)
This is the process of organising those records into a system to calculate your total profit, loss, and expenses.
Examples include:

Helps you understand your business performance in real-time
Key Takeaway:
You can technically keep all your receipts in a shoebox and hand them to an accountant at the end of the year. That satisfies "record keeping."
But without "bookkeeping," you won't know if you are making a profit until it is too late.
While not legally mandatory, running an eBay business without a bookkeeping system is risky.
Advantages
Audit Protection
If HMRC investigates you, they will ask to see how you calculated the figures on your tax return. A clear bookkeeping system provides a "digital audit trail" that matches your bank statements to your sales.
HMRC Enquiry Manual EM4650:
Failure to keep adequate records can lead to penalties of up to £3,000.
Accurate Margins
eBay fees, ad fees, and shop subscriptions are complex. Bookkeeping helps you see your true profit per item, not just the cash in the bank.
Claiming All Expenses
It is easy to lose a £50 receipt for packaging tape. If it is booked immediately, you claim the tax relief. If it is lost, you pay more tax.
Disadvantages
Cost
Accounting software (like Xero, QuickBooks, or Link My Books) costs money (monthly subscriptions)
Time
It takes discipline to sit down once a week to reconcile your accounts
Complexity
Understanding how to split "Gross Sales" vs "Net Payouts" from eBay Managed Payments can be confusing for beginners
Yes, absolutely. You do not need a qualification to do your own books.
However, be aware of the "Knowledge Gap." Professional bookkeepers train for years (often AAT qualified) to understand account codes, capital allowances, and VAT rules.
