What is Cessation of Trade?
The tax rules that apply when a sole trader or partnership permanently stops trading, including how the final period of profit is taxed and how any remaining overlap relief or terminal losses are used.
Full Definition
Cessation of trade refers to the point at which a sole trader or partnership permanently stops carrying on their business, triggering a specific set of tax rules for the final accounting period rather than the normal ongoing basis period calculation. Since the tax year basis was introduced from 2024/25 under basis period reform, the final tax year of trading is simply taxed on the actual profits arising from the end of the previous tax year to the date trading ceases, which can be a period of more or less than 12 months depending on exactly when in the tax year the business stops. Any unused overlap relief carried forward from the pre-reform current year basis rules is fully deducted in this final period, which for many long-established sole traders converts what would otherwise be an unused historic relief into a genuine reduction of their final tax bill. On cessation, a trader must also deal with unsold stock and other assets: stock is normally valued at the higher of cost or the price paid by a connected party taking it over, while other business assets sold or transferred out of the business can trigger Capital Gains Tax, potentially with Business Asset Disposal Relief available on the disposal of the business itself (rather than just individual assets) if the qualifying conditions and the two-year ownership test are met. Capital allowances also stop at cessation: instead of the normal writing-down allowance, a balancing allowance or balancing charge is calculated by comparing the tax written-down value of the pool with what was actually received for the assets, crystallising any over- or under-relief claimed during the life of the business in one final adjustment. Worked example: a sole trader who has claimed capital allowances leaving £4,000 of tax written-down value in their main pool, and who sells the remaining equipment for £2,500 on ceasing to trade, gets a £1,500 balancing allowance (additional deduction) in the final tax year; had they instead received £6,000 for the equipment, they would face a £2,000 balancing charge added back to taxable profit. Terminal loss relief is available if the final 12 months of trading produce a loss, allowing it to be carried back up to three years against earlier profits of the same trade, which can be the only way to obtain relief for a loss made just as a business is winding down with no future profits to carry it forward against.
