Tax code incorrect

I have had my tax code changed to allow for interest on my savings. As far as I can see it has been calculated with me being a higher rate of tax payer, but I am not I am within the tax threshold this year and will also be in the next tax year due to salary sacrifice, so how can I get this corrected so that I get my full £1000 tax free allowance?

Hi,
Unfortunately, it is not possible to check individual tax records through this forum, if you have a question which relates to your personal tax situation or tax code please contact our Income Tax team:  
Income Tax: general enquiries 
On this page you will also see a link to the personal tax account, which may be the quickest way to review information relating to pay and tax history, tax codes and how to change them. 
Thank you.
