Foreign incomes, self assessment

Hi. I have few questions. In tax year 23/24 I worked abroad at sea on a cruise ship as a musician, it was only one source of my income. The agency which hired me registered in Panama, but ship under Maltas flag, itinerary outside of UK, salary was in Euros. I’m going to fill in my self assessment. I’m not interested in Seafarers earning deductions because the incomes in total approx 12500 under tax free allowance. But should I declare this money as a self employed or employed ? Because I was doing short contracts few months each for this company. And how should I pay NI ?

Hi,
You will declare this as self employment and convert the income to sterling. This will then determine any National Insurance due.
Thank you.
