I have successfully claimed the Severe Disability Premium on ESA (the award letter came yesterday.) Today I have received a letter saying that I now have to pay tax and owe £600 for 2020/21. I have been on Income Related ESA since 2016 and have never paid tax. Does anyone have any idea why I would start paying tax now? TIA.
PS. I receive an occupational pension of £25 per month which is deducted from my ESA.
