Stop Being Self-Employed: UK Closure Checklist 2026/27

When a sole trader stops trading, they must tell HMRC, file a final tax return and close any connected VAT, PAYE or CIS registrations. Simply submitting no further invoices does not automatically end Self Assessment or cancel future filing notices.

This 2026/27 closure checklist covers the cessation date, final accounts, tax reliefs, Making Tax Digital and post-trade records.

1. Decide the actual cessation date

The cessation date is when the trade permanently ends, not necessarily the last customer payment or the date the bank account closes. Record the final date on which the business carried on its normal activities. Later collection of debts or payment of closing costs does not always move that date.

If you are stopping registration only because gross trading income will be £1,000 or less, GOV.UK says to report the cessation as 5 April, the end of the tax year. You can remain registered where this supports evidence of self-employment or voluntary Class 2 National Insurance eligibility.

2. Tell HMRC you stopped being self-employed

Use HMRC’s online cessation service and provide:

• your National Insurance number;
• your Unique Taxpayer Reference;
• the business name and cessation date;
• contact and repayment details where requested.

Telling HMRC that the trade stopped is separate from asking to leave Self Assessment. You may still need returns because of rental income, gains, foreign income, the High Income Child Benefit Charge or another reason.

3. File the final Self Assessment return

The return for the tax year containing cessation must include:

• all trading income to the cessation date;
• allowable running and closure expenses;
• stock and work in progress where relevant;
• debtors, creditors or cash-basis adjustments;
• capital allowances and balancing charges or allowances;
• business asset disposals and possible Capital Gains Tax;
• the final profit or loss and cessation date.

Closing costs such as notifying customers, postage, professional fees and account termination charges may qualify where incurred wholly and exclusively for the trade.

4. Check basis-period and overlap adjustments

Basis period reform aligned unincorporated business profits with the tax year from 2024/25. Historic overlap relief should normally have been used during transition, but cessation computations can still require review of prior-year figures and transitional profit spreading. Do not deduct the same overlap profit twice.

5. Use terminal loss relief where available

A qualifying trading loss in the final 12 months may be carried back against profits of the same trade for the previous three tax years, using the statutory order. This can generate a repayment but requires a claim and supporting final accounts. Compare terminal relief with other loss options before the claim deadline.

6. Deal with business assets

Selling equipment, vehicles, stock, goodwill or premises can create:

• taxable trading receipts;
• capital-allowance balancing adjustments;
• Capital Gains Tax gains or losses;
• VAT on disposals;
• market-value adjustments for assets retained personally or transferred to connected people.

Business Asset Disposal Relief may reduce qualifying gains where its detailed ownership, trading and disposal conditions are met. A cessation does not make every asset disposal eligible.

7. Cancel or transfer VAT registration

A VAT-registered sole trader must normally cancel registration within 30 days of ceasing to make taxable supplies, unless the business is transferred and the registration is validly transferred. File the final VAT return and consider output VAT on stock and assets held at cancellation where the statutory threshold and conditions apply.

Do not cancel too early if the business still sells assets or makes taxable supplies. Post-cancellation VAT adjustments and claims use specific HMRC routes.

8. Close PAYE and payroll

If you employed staff:

1. pay final wages and statutory amounts;
2. mark the final Full Payment Submission correctly;
3. issue P45s;
4. settle PAYE and National Insurance;
5. close pension and benefits processes;
6. close the PAYE scheme where employment has ended.

Keep payroll records for the required retention period after closure.

9. Update CIS registration

A contractor or subcontractor registered under the Construction Industry Scheme should contact the CIS helpline when trading ends. Submit outstanding monthly returns, verify deductions and keep payment and deduction statements.

10. Making Tax Digital cessation

A person within MTD for Income Tax must tell HMRC the date the income source ceased through their online or agent services account. Send the final quarterly update covering the cessation date and include the ceased trade in the final tax return through compatible software.

If all self-employment and property sources have ceased, MTD will normally stop after that tax year. Continuing sources still require digital records and updates.

11. Payments on account

Future payments on account may be reducible if the next year’s qualifying liability will fall. Do not reduce them automatically to zero where other untaxed income remains. An excessive reduction can create interest when the final liability is known.

12. Ask HMRC to withdraw future returns

After filing the final return, use HMRC’s service to close the Self Assessment account or ask to be removed for a particular tax year if no other criterion applies. HMRC will confirm whether a return is still required. If a filing notice arrives before confirmation, respond rather than ignoring it.

13. Keep records after closure

Retain accounts, invoices, bank statements, payroll, VAT, asset and tax-return records for the applicable statutory period. For a sole trader filing on time, business records are generally kept for at least five years after the 31 January submission deadline for the relevant tax year; longer periods can apply for late returns, enquiries, losses, assets and deliberate inaccuracies.
