Self employment income classified as in UK or overseas

I am currently in UK as resident, not citizen. I continue my part time job online after migrating to UK last year. The earnings / transactions are in HK and deposited in a bank in HK. What should the income be classified as arise in UK or overseas? Do I need to contribute NI for the income? If it is needed, the taxable income should be before or after the deduction of the NI portion ? Thank you

Hi SFWong,

You will need to determine your employment status by referring to:

Employment status

Either way, you will be responsible to pay the NI and you will report the gross income received and then any allowable expenses on a Self Assessment  tax return. 

Thank you.
