In fact, VWRD (also VWRL) still has tax reporting issues, due to the need to consider “excess reportable income”. See, for example, https://global.vanguard.com/portal/site/loadPDF?country=global&docId=18747
This report says that these USD per share dividends were made in the accounting period 1 July 2017 to 30 June 2018:
0.1822 21/09/2017 (goes on 17-18 UK tax return)
0.2068 21/12/2017 (goes on 17-18 UK tax return)
0.2075 22/03/2018 (goes on 17-18 UK tax return)
0.2028 21/06/2018 (goes on 18-19 UK tax return)
However, there is also listed a $0.0442 per share “Excess of reportable income over distributions”. In a UK taxable account you are meant to pay tax on this as a taxable dividend. If you held 1000 shares, this would be $44.20. You would pay dividend tax, and then increase your basis cost for these shares by $44.20. This is deemed paid 31/12/18 so needs to go on the 2018-19 tax return, converting to GBP at the exchange rate of 31/12/18. So the paperwork is very similar to that for an accumulation fund like VWRA or VWRP.
Having said this, I struggle to find on the Vanguard web pages the tax reporting information for an accumulation fund such as VWRA/VWRP. Perhaps I am meant to find it by adding up the five figures above report for WVRL?
For ETFs that come in only an accumulation type, like VVOL, the report does give a figure.
I would be very interested in further discussion of these points.
