Self Assessment - getting charged tax on less than £1k dividend

[css_jay99]

Certainly showing in the computation as Dividend. Income is over £100k.
I came across a post on the HMRC forum with similar observation and an explaining of how HMRC pre-allocate the pots of income against Personal allowance but at the end of the thread an admin said it was wrong and to contact HMRC.

Current on inside IR35 and filling out my Self Assessment.
I included a £500 dividend from ltd company and the Tax computation is including a charge on the dividend at 20%. I thought dividend allowance is £1000 for 2023/24 regardless of income so nothing to pay ?

Online calculators are showing the same so which is HMRC site behaving different?

Sounds odd. 20% isn't even a rate that would be applied to dividends.

Double check that the 1000 isn't against employment income rather than dividend.

Although I wonder if something odd happens if you've earned over 100k, which is where you lose £1 off your personal allowance for every £2 earned.
