 We would like to take the opportunity now to point out some possible free resources, free resources that might be useful to follow along in this course, although not required, free resources that could be useful in practice, free resources that you might be able to give as advice to others who have particular income tax needs. The first one, one we saw in a prior presentation is LASERT tax software. This is the software we will be using in the demonstration problems. You don't need access to the LASERT tax software to follow along. It's not going to be a course on the data input in LASERT tax software, but having tax software so that we can tinker with the tax code by running scenarios is a really useful tool for understanding. You might be able to look into the free trial on the LASERT tax software as well as some of the other softwares we've kind of touched in on in prior presentations, and we'll look at here shortly.
