The subject heading of the question states S corp. I wasn't aware you could file S Corp taxes with a personal version. I'm being sarcastic. Determining basis is huge for small companies who are trying to use turbo tax for tax reporting so to tell someone it isn't possible is doing a huge disservice to them.
My husband always used a tax professional from the start of his company and not one of them advised him of the need to have this determined. Turbo tax made this so much easier once I realized the need of determining the need for it because of years with loss.
