Dividend tax rates and allowance
The dividend allowance and the three rates, one row per tax year, with the source each figure was read from.
The dividend allowance is not an exemption. It is a nil rate band, so the dividends covered by it still use up room in whatever band they fall in, and they still push the dividends above them into the next rate. Treating it as an exemption understates the tax for anyone near a threshold.
These are the figures the calculator on this site applies. It reads the same table this page prints, so a rate on this page cannot quietly differ from the figure in a report.
Dividends go on the main Self Assessment return and are treated as the top slice of income, which is why the rate that applies depends on the wages, pension and interest sitting underneath them. A Scottish taxpayer pays these same rates in the same UK wide bands, because the Scottish rates apply to earnings and not to dividends.
Every year held
Where the dividend table itself carries no source, the row shows the citation the income tax table holds for that year's dividend figures, which is where the provenance for those years is written down today.
Every row here carries the source the figure was read from. A row that carries none is not printed, and a short line says which year was left out instead. That is deliberate. A rate with nothing behind it is the one most likely to be wrong and the hardest for a reader to check.
