RE: Incorrect tax calculation from HMRC 2022 Self Assessment returnI also seem to have a similar problem with 2021/22 tax return. Tax is being calculated on 2,000 GBP dividend allowance free value. The return seems to be adding 2,000 GBP to a total income taxable value for the year and then calculating extra tax on this amount. Is there a known glitch with the return for 2021/22? My circumstances are very straightforward. I have one full time employment (higher tax rate) and I'm a director of a limited company. I'm not paying myself directors' salary, just drawing 2,000 GBP dividends. I have updated relevant fields of the tax return form: Full time employment details with pay to date and tax to date and, 2,000 GBP dividends in section "Did you receive any dividends, for example, from UK companies, authorised unit trusts, open-ended investment companies, foreign companies (up to £2,000)? " I've triple checked and I cannot see any other relevant fields I might have missed or needing updating specific to my earnings. Any help on the above would be much appreciated.
