Clarification on Tax Obligation for Interest Income and Offshore Accounts

Dear HMRC, I hope this email finds you well. I am writing to seek clarification regarding my tax obligations, particularly concerning interest income and the requirement to submit a Self Assessment (SA) form. My salary is approximately £55,000 per year, and my interest income from various sources is below £10,000. As a higher rate taxpayer, I understand that I have a £500 allowance for tax-free interest income. However, I am confused about whether I am required to submit a Self Assessment form under these circumstances, given that my interest income does not exceed £10,000. Additionally, a portion of my interest income is derived from offshore accounts. Could you please confirm whether I need to submit a Self Assessment form due to this foreign income, regardless of the total interest being under £10,000? Thank you for your time and assistance. I look forward to your clarification on this matter.
