[Question] Investing to donate vs getting tax relief (UK-focussed)

Hello, I’m interested in people’s views and directions to resources about whether it seems better to invest to donate or to donate now and obtain tax relief from the UK Gift Aid scheme, which effectively pays back the income or capital gains tax paid on donated money.

The question is at what bands of tax relief would it make more sense to donate now than to invest and donate later, for each of the cause areas global health/​development, animal welfare and longtermism? Any views on any of those areas would be useful.

Some more notes:

Through Gift Aid, a basic rate taxpayer gets a “return” of 25%, a higher rate taxpayer 67% and an additional rate taxpayer 82%. Whilst it seems that in the USA people could donate to a donor advised fund to invest and still get the tax relief, this doesn’t seem to be viable in the UK for non-huge donors (e.g. as discussed here). So Gift Aid is rather use-it-or-lose-it in character. (Though there is the Patient Philanthropy Fund for supporting longtermist causes—but I’m also interested in other cause areas, and I’m not sure about paying into an organisation’s fund.)

The question of whether or not to invest funds to donate later has been explored in several places. E.g. this Founders Pledge report estimated the expected impact of investing funds in the stock market and donating them after 10 years to be 9x that of donating now for longtermist causes, 2.1x for global health and 4.2x for animal welfare (though the pdfs were very skewed and median impact ratios for global health and animal welfare were a lot lower at 1 and 1.7 respectively). Philip Trammell’s report also goes into a lot of depth and argues for investing rather than donating now for people who value all times equally. There are quite a few more articles I’ve looked through in the Timing of philanthropy and Patient Altruism Forum topics.

The Founders Pledge report seems to suggest it would be worth delaying donations in expectation for all causes for any tax relief band—but I’m wary of putting a lot of emphasis on one report, and also you get the opposite answer if the most probable results are used for global health and for higher/​additional rate taxpayers for animal welfare. Other articles don’t seem to quantify how much better investing and delaying donating would be, so I can’t see at what level of tax relief it makes sense to donate now.

Thanks very much if you can help.
