What Is the Sole Trader Year-End in the UK?
For most sole traders, the tax year runs from:
6 April to 5 April
You must report your income and expenses to HM Revenue & Customs (HMRC) via a Self Assessment tax return.
Proper sole trader year-end preparation ensures:
- Accurate profit calculation
- All allowable expenses claimed
- Correct tax liability
- No last-minute panic before the 31 January deadline
Sole Trader Year-End Checklist (UK)
Use this practical checklist to get organised before sending information to your accountant.
1️⃣ Confirm All Income Is Recorded
Your accountant will need a full record of:
- Sales invoices issued
- Payments received
- Cash income
- Bank transfers
- CIS deduction statements (if in construction)
Missing income can lead to compliance issues with HMRC — accuracy is essential.
2️⃣ Gather All Business Expenses
To maximise tax efficiency, ensure you have:
- Receipts for purchases
- Fuel and mileage records
- Phone and internet bills (business portion)
- Insurance documents
- Software subscriptions
- Office costs
- Subcontractor payments
- Tools and equipment purchases
Claiming allowable expenses correctly reduces your taxable profit.
3️⃣ Provide Full Bank & Finance Records
Your accountant will need:
- Business bank statements (6 April – 5 April)
- Business credit card statements
- Loan agreements
- HP or lease agreements
- Details of finance balances
Every transaction must be accounted for and reconciled.
4️⃣ Declare Capital Purchases
Large purchases such as:
- Vans
- Equipment
- Machinery
- High-value tools
May qualify for capital allowances, which reduce your tax bill.
5️⃣ Identify Personal Drawings & Private Use
If you’ve taken money out of the business, this must be clearly recorded as drawings — not expenses.
If you use:
- Your vehicle personally
- Your phone for personal calls
- Your home as an office
Your accountant will need details to calculate private use adjustments.
Common Sole Trader Year-End Mistakes
Many sole traders make the same avoidable errors:
- ❌ Mixing personal and business transactions
- ❌ Not reconciling bank accounts
- ❌ Missing receipts
- ❌ Forgetting CIS suffered
- ❌ Leaving bookkeeping until January
These issues often increase accountant fees because of additional clean-up work.
How Xero Makes Sole Trader Year-End Easier
Using Xero accounting software correctly can streamline your entire year-end process.
When set up properly, Xero allows you to:
- Automatically import bank feeds
- Reconcile transactions in real time
- Upload receipts via mobile
- Track CIS deductions
- Generate profit and loss reports instantly
- Share access directly with your accountant
Instead of sending spreadsheets and paperwork, your accountant can log in and access organised, real-time data.
However, many sole traders have Xero set up incorrectly — leading to coding errors and reporting issues.
