Self assessment foreign incomes

I'm not a UK tax resident. In going through the Self assessment tax return Step 7: Do you need to pay tax on any of the following? Does this refer to paying tax in the UK only? (I have incomes in Hong Kong and had paid income tax there, but not over here since I'm not a UK tax resident. Therefore I put down "none"; was my understanding correct?) Thank you for your advice!

Hi,

As a non resident it will only be your UK income that you declare.

Thank you.
