Hi Ray,
Your 25/26 tax code has most likely been reduced to 1062L by a prediction of what your untaxed interest will be in 25/26.
This predicted amount is based on your previous year's interest, and is added to your code to help you pay the correct tax on 25/26's untaxed interest. That said, you are entitled to The Personal Savings Allowance of £1000, and the Starting Rate for Savings of £5000 - additional tax free allowances that are applied to savings income (
Tax on savings interest).
If your other income for 25/26 (pensions, employment, etc) exceed the tax free allowance represented by your tax code (1062L means £10,629 tax free income), then these additional savings allowances would be applied, and your total tax free allowance of £12,570 would be restored, either immediately, or following the end of the tax year.
As for your rebate, if we are still awaiting confirmation of your 23/24 interest figures, and you have those figures, you can provide them to trigger your rebate - you can contact us by webchat, post or phone via
Income Tax: general enquiries to confirm your figures.
Thank you.
