Lower income savings allowance

If my income falls somewhere between £12K and £17K per annum, but my income from savings exceeds the automatic lower rate tax entitlement of £1,000 per annum, will my self assessment tax calculation automatically give me the additional Lower Income Savings Allowance that I understand I'm entitled to?

It sounds like you are referring to the "starting rate for savings". That in particular isn't something I've received, but allowances of this type are automatically implemented in the online self assessment calculation and don't require you to do anything to claim them, beyond filling in your income data. There is an option to view your full calculation before submitting a return online, which should let you confirm that it really has been included.

Hi Bayleaf,
If your other income is lower than £17,570, and your Savings Interest exceeds the Personal Savings Allowance of £1,000, you will receive the Starting Rate for Savingsa allowance of £5,000.
This should be applied automatically on your Self Assessment calculation.

Thank you.
