This is a linear product built to take one from front to back of the process. If you want to navigate to something like how to estimate next year's tax burden, that's a little tougher to find. Because all the prior years' return data are stored within the system, it would be too cumbersome to switch to somebody else. Fortunately, navigation seems to be getting a bit better each year. But this is not a product that you can easily look "under the hood."
