Non-residents income from National Savings & Investments

Hi, Some your threads replies don't match with the gov.uk information and i need to clarify the following: I am Non-resident and I have earn ONLY interest by National Savings & Investments. No any other type of income in UK 1. Should I fill HS300 Non-residents and investment income and submit to self assessment ? 2. If yes how much may be the tax that I need to pay for around 8000 ? 3. If no why ? Because tax is 0 or because this type of income is not taxable and should be declare it to my home country ? Thanks in advance

Hi
Please refer to guidance at Tax on your UK income if you live abroad

According 'double taxation treaty' between Switzerland and United Kingdom where is the earned interest by National Savings & Investments taxable? Switzerland or United Kingdom ? Thanks  

Hi,
Certain types of income from National Savings and Investments (NSI) are tax exempt in the UK:
Savings and investment income: tax exempt savings
Article 11 relates to all types of interest:
