Not sure if I posted this already but I found this and thought it was valuable information for anyone who needs it. If you use Turbo Tax Business for your business returns it basically completes From 7203 for you. Go to forms, 1120S, Information WKS, scroll down to k-1 and check box for Yes, calculate stock basis limitations worksheet, this is where it basically does Form 7203 for you other than your starting basis.
