Thanks everyone for coming!!

I'm hosting attempt #2 for a summer picnic on 4th August. Sign up here:

Unless Ben is fundraising to scale up his snack granting operations, he likely doesn't need to conduct a thorough externally legible analysis.

However, this is a spreadsheet-friendly picnic so he would be welcome to do so.

Hey, we're on the blue tartan picnic blanket and I'm wearing a green skirt

Really excited to see this post! I've written a very early draft of something similar so very pleased that it’s already been done (likely better than I would have) so thank you 🤓

My background is Transfer Pricing at a Big 4 but I’ve moved into tax tech. I'd be interested in coordinating tax nerds interested so anyone reading this that would be interested then please message my EA forum account (I’ll make something happen if there’s enough people but also very happy to just chat about tax).

I think this would be valuable since:

  • I’ve had some great conversations with other EAs interested in tax policy
  • I'd love to see more posts like this [1]and it’d be great to get help building out the Tax Policy wiki on the EA forum 
  • Having a space like this would be a great gateway for mid career folks already in Tax to think about how to use their skills for good (or to start donating effectively)
  • My take is that, for those just starting their careers and looking to build career capital, a tax graduate scheme with a large international firm is a decent career first step.
    • Pay is solid for a fresh graduate meaning you can have an immediate impact by giving a % to effective charities.
    • Depending on the department, the hours are not crazy meaning you can do side projects and volunteer to keep engaged in EA stuff.
      • In particular, working on EA workplace groups in these key orgs seems valuable for broader community engagement
    • Large firms tend to have great learning and development opportunities. They will often pay (and give you time off to study) for professional qualification in accountancy and/or tax which is very transferable to an operations/organisation building skillset.

    • The international tax space was also an area that I thought might have been an interesting case study for AI Governance (there was a request for those here) given the conflicting incentives between countries. There's potentially interesting overlap between International Tax Policy and AI Governance if the technology is as economically transformative as some think and how tax policy could be used to redistribute benefits globally.


Since they were well received last year, I'm going to be hosting the EA London Quarterly Review Coworking sessions again for 2024.

Thanks to Rishane for making this poster and to LEAH for hosting us. 

Thanks for all your support!!! Very excited to have you join us in London ❤️

Absolutely agree - although I'm one of the other GWWC London co-leads so I am also biased here. I think low commitment in person socials are really important and tbh the social proof of meeting people like me who donated significantly was the most important factor for me personally.  

I'd would like to see people be a lot more public with their pledges. I personally think Linkedin is underutilised here - adding pledges to the volunteering section your profile is low effort but sets a benchmark.

I've personally added my pledge to my email signature, but I think this depends a lot on the kind of role you have, the company you work for and if you think the personal reputation risk is worth the potential upside (influencing someone else to donate more to effective charities). 

I think this could be especially powerful for senior people who have a lot of influence but equally I've had a few meaningful conversations with people off the back of it. 

I've got a half-written post on this for this forum series and Alex from @Giving What We Can has created some fantastic banner images for LinkedIn profiles. Some resources from GWWC:

Donating anonymously: Should we be private or public about giving to charity? · Giving What We Can

Why you should mention the Pledge in your LinkedIn summary · Giving What We Can

Great comment - I'd add that usually GWWC pledges in the UK are based on pre tax so it wouldn't actually cost the full £5k. Donations reduce your income for income tax purposes (but not NI) - Payroll Giving (UK) or GAYE - EA Forum (


£50k salary 

£3.75k donation which is grossed up by 25% from your taxes with gift aid to £5k

If you actually donated £5k then that would be a £7.5k total donation when grossed up with gift aid. 

However, the higher rate tax (40%) band starts at ~£50k a year so every £1 donated above that costs 60p 

(Working on a longer explainer on this which updates this piece UK Income Tax & Donations — EA Forum ( but you can check out the underlying spreadsheet which create these graphs here: UK Income tax (including NI) - Google Sheets)
