Self assessment registration for savings income

I would like to register self assessment online for savings income. I don’t know which option to be appropriate for this purpose. Thank you for giving me advice.

Hi Hon Kei Cheung,
The interest from your savings will need to be more than £10,000 to complete a Self Assessment tax return
Check if you need to send a Self Assessment tax return
To register you would submit a SA1 form:
Register for Self Assessment if you are not self-employed
Thank you.
