Good morning I used to be a basic rate tax payer but recently moved to the higher rate category. As I have fixed bond savings which will accrue interest this financial year 24/25, I would like to find out whether my personal savings allowance will stay as £1000 or decrease to £500. Does the HMRC calculate one's income combining the salaries through the year and then establishing whether the total is above or under £50,270? If positive, will any interest exceeding the personal savings allowance of £1000 be taxed at 20% or 40%? Finally, how can any tax due be paid, except for adjusting one's tax code? My situation will be different in the next financial year 25/26. The information available on https://www.gov.uk/apply-tax-free-interest-on-savings and https://www.gov.uk/income-tax-rates does not answer these questions. Thank you in advance. S
