The gifting stock to children strategy is limiting the taxpayer to $2,300 for 2022, which is the Form 8615 limit for 1 child.  The client I am working on has 2 children in college, so this should be doubled.  Seems like the number of children could be an input field.  Also, the applicable tax rates for the savings are calculating at the taxpayer's Federal marginal rates (should be their Federal capital gain rate instead), their state marginal rate (OK, but my state cut the rate between 2021 and 2022), and it does not include their net investment income tax rate.  If the assumption is that the parent is paying the tuition as the baseline, then there is not an incremental out-of-pocket cost to giving the child(ren) appreciated stock instead.  It appears that none of these issues can be modified in the program.
