Hey James.

My understanding is you will receive a statement to help with your tax returns. Tax returns themselves will be relatively straightforward with this fund as far as I know.

However, the adverse tax implications of owning an ETF which is domiciled (or run from) another country is that it can come with possible estate tax complications in certain scenarios. This post goes into some detail about it: https://passiveinvestingaustralia.com/fund-do...

If you wanted a fund which is focused on the S&P 500 which doesn’t come with this issues, then IVV would fit the bill. Domiciled in Australia and tracks the same underlying stocks. Obviously there may be tax outcomes if you sell your current holding in VOO, but something to consider perhaps.

Hope that helps.
Dave
