From the announcement:
The July gross dividend is increased to offset the element of Dutch withholding tax applicable.
I'm surprised to see a withholding tax here, within the EU. I know I've filled in explicit paperwork to avoid withholding tax being when paid from the US, who make it easy when an asset is held in a SIPP but harder in other circumstances.
Given that all my taxable assets are tax-sheltered in a SIPP or ISA, am I needlessly paying tax here, and perhaps on other offshore investments?
