Post-Cessation Transactions: How Income and Expenses Are Taxed

This guidance is for self-employed individuals and sole traders who have ceased trading but continue to receive income or incur expenses after their business has formally closed.

This page explains how post-cessation transactions are treated for tax purposes, including receipts received after closure and expenses incurred once trading has stopped.

Many people assume that once a business has ceased, nothing further needs to be reported. In reality, certain receipts and expenses after cessation may still need to be included on a tax return. Getting this wrong can lead to incorrect Self-Assessment filings and potential HMRC challenges.

What are post-cessation transactions?

Post-cessation transactions arise when amounts are received or expenses are incurred after a trade has stopped, but relate to that former trade. These transactions do not disappear simply because the business has closed.

Common examples include late customer payments, refunds, or professional fees incurred in finalising the affairs of the business.

Post-cessation receipts

Income received after a business has ceased may still be taxable if it relates to the former trade. Typical post-cessation receipts include:

• Late payments from customers for work carried out before cessation
• Refunds or settlements connected to the former business activity
• Amounts recovered that were previously written off

These receipts are usually taxed as post-cessation income and must be reported, even though the trade itself has ended.

Post-cessation expenses

Some expenses incurred after cessation may still qualify for relief where they are wholly and exclusively connected to the former trade. Examples include:

• Professional fees for final accounts or tax compliance
• Costs involved in recovering outstanding debts
• Legal or administrative costs relating to closing the business

Only expenses that meet the relevant conditions can be claimed, and careful judgement is often required.

Risks and consequences of getting this wrong

If post-cessation transactions are overlooked or treated incorrectly, this can result in:

• Underreported taxable income on a Self-Assessment return
• Disallowed expense claims if costs do not qualify
• HMRC amendments, interest, or penalties if errors are identified later

These issues often arise because taxpayers assume that no reporting is required once trading has stopped.

In practice: what we commonly see

In practice, post-cessation income is frequently missed because the business is already closed and bank accounts may no longer be actively monitored. We also see confusion around which expenses remain allowable after cessation, particularly professional fees. These grey areas are often only picked up when HMRC queries a return or opens an enquiry.

Review whether receipts after closure affect your tax return
