Casual consulting income under £1k in 23/24 tax year.

I was employed and paid tax PAYE for three months in 23/24 tax year and then retired early taking a small pension from a previous employer's scheme. Towards the end of the 23/24 tax year I was offered some casual consulting work for which I was paid £600 gross. How should I declare this income on my SA return ? I have completed an SA assessment for many years previously. Should I answer 'yes' to income in self employement, albeit the income is less than £1k, and complete SA103, or declare under miscellanoeous income? Thanks.

Hi Trevor Turner,
As this income is covered by the £1000 trading allowance, you do not need to declare it on your Self Assessment tax return.

Thank you.
