Self-employed / remote worker for UK company

Hey everyone!

In November I have finally received my spouse visa, my husband is Japanese.

I currently work remotely for a UK based company, so I am self-employed, need to file my own taxes and pay health insurance.

I am so new to this, my husband knows how to file taxes but doesn't know much about freelance.

Is it easy to register? Do you think I should hire a Tax accountant or not worth it?

I speak Japanese, but not good enough yet for Bureaucracy. Thanks
