I put this together over the last few days to show my wife's siblings (all younger than me, all single and aged 20-25). It starts with a brief overview of how taxes work, then describes different basic investment accounts, and finally talks about how to make basic smart investment decisions and how to get started. It's 26 slides long.
This presentation is not intended to be a comprehensive guide to taxes or investing. It's intended to give someone in their early twenties the basic knowledge they need to start making smart savings decisions.
Take a look and please tell me if you have ideas to improve it or if you find anything wrong in here.
