Thank you. And am I able to claim any tax back if I have been taxed at source in the Netherlands?

I am a UK resident, currently employed full time at a UK university (£32k annual salary). In March, I completed work for University of Amsterdam; I had to invoice them in dollars ($3,608) and received payment on my UK account (£2,753) as a bank transfer. It was my only income outside of my full time UK university role. Do I need to pay income tax and how do I do that? I have never filed self assessment, I'm unsure if I need to register as self employed for this job I completed.
