foreign income

If I help a student in UK to have tutorial. But their parent pay the money in HKD to my HK bank account. Then I need to put this income into the foreign income, or just use the currency rate to change it back into same amount of GBP and add it into my general income?

Hi,
This is foreign self employment income. As no tax was deducted from it, you can declare it in the SA103 for self employment. You will need to convert to UK pounds sterling.
Thank you.
