What is full relief under section 783AE of the Income Tax (Trading and Other Income) Act 2005?

Full relief under section 783AE means that an individual's relevant income is not chargeable to income tax at all. It applies automatically where relevant income does not exceed the £1,000 trading allowance and the individual has not elected to disapply it under section 783AL or claimed partial relief under section 783AM.

How does the cash basis affect eligibility for full relief under the trading allowance?

If the cash basis of accounting causes relevant income to exceed the £1,000 trading allowance, an individual may still qualify for full relief under section 783AE. This secondary route applies where using GAAP instead of the cash basis would bring the relevant income back within the allowance, ensuring the accounting method does not accidentally disqualify the taxpayer.

Can a taxpayer opt out of full relief under section 783AE?

Yes. An individual can elect under section 783AL for full relief not to apply, for example to recognise a trading loss. Alternatively, they can elect under section 783AM for partial relief, which allows the trading allowance to be deducted as a flat-rate expense instead of claiming actual expenses when income exceeds the allowance.

Does an individual need to report income on a tax return if full relief applies?

No. Where full relief applies under section 783AE, the relevant income is simply not chargeable to income tax. The individual does not need to calculate profits, claim expenses, or report the income on a tax return. This makes the trading allowance a straightforward exemption for small amounts of trading or miscellaneous income.

Income Tax (Trading and Other Income) Act 2005 section 783AE

Full relief: introduction

Section 783AE sets out the circumstances in which an individual qualifies for full relief from income tax on their relevant income where that income falls within the trading allowance.

An individual qualifies for full relief if their relevant income does not exceed the trading allowance (£1,000) and they have not elected to disapply it
Full relief may also apply where relevant income exceeds the trading allowance but only because the cash basis of accounting inflates the figure — if using GAAP the income would fall within the allowance
The individual must not have made an election for full relief not to apply (section 783AL) or an election for partial relief (section 783AM)
Where full relief applies, the relevant income is simply not chargeable to income tax at all — there is no need to calculate profits or claim expenses
