That is why in my scenario I used effective tax rate. Obviously there are many factors that could determine the effective rate. No matter what tax structure/system that is in place there will always those trying to get away with not paying taxes. Tax planning will be a key, and as a CPA, it keeps me employed.
Then I need to mention that anyone that makes 3 mil and has an effective tax rate of 35% needs to get a new CPA. With that said, how much more could you help someone with investing and planning for the future that you now spend trying to change the past to not pay taxes?
