do I need to declare small external examiner fee

I am employed by a UK university. Outside of work I was invited to undertake PhD external examination for an Australian University. I have received a small payment (less that £300), this has just been paid in to my personal account. Do I need to declare this for tax purposes and if so how? This is the only payment outside my usual work received.

Hi debmo,

The guidance here: 

Check if you need to send a Self Assessment tax return

Advises that as you were in receipt of foreign income, you must complete a Self Assessment Tax return and declare the foreign income, regardless of how much the income was.

Thank you. 

That's so prohibitive for the global academic community. It will prevent the sharing and supporting of research development in nursing care.

But thank you anyway for providing the information
