paying taxes from remote work for a company from abroad

hello. :) I am currently employed in a Polish company and work exclusively remotely. this year I'm moving to the UK with visa family - i am joining my partner in the uk. Since there is little chance that I will find employment in the UK immediately, I plan to continue working for the Polish company remotely. However, this company does not employ anyone from the UK and does not provide services here. what must the employer do (register employment or me as an employee) to pay income tax and NHS for me? I also read that I can register myself and pay income tax and NHS for foreign income - does the government consider this as full employment and, for example, does it build my creditworthiness for the next years? i am just looking for the best way to pay taxes and nhs - in such a way that the government will treat me as a full-time employee with full-time job

Hi RY5,
This would be treated as self employment and you would need to register for self assessment and complete a tax return to declare this - Working for yourself.
Thank you.
