Missed 200 GBP of dividends for my self-assessment

Hi, I have filled my self-assessment form for the 2023-2024 indicating zero dividends. However a couple of months later I learned from the broker that apparently despite selling some funds in the 2022-2023 tax year, the dividends we attributed to 2023-2024 tax year. The total amount is 200 GBP which is below the allowance that is taxable (according to my understanding). So my question is, should I update my self-assessment form, or can I leave it as it is as it is below the taxable allowance. Thank you

Hi sksksk,
You will still need to amend your tax return, but if below the dividend allowance tax will not be due:

Thank you.
