Points well taken. The IRS confuses things by its FAQ (agreed to by HR block mortgage interest and SALT - if the text is read). As an agency, the IRS needs to more forcefully interpret the law in context - which it is not. the current FAQ is guides strongly to MFS for the full $10K on SALT. The black & white read of the law is too harsh - there is legal and implementing agency interpretation. However, Turbo is designed as a mainstream tool and not to challenge the IRS - thus it takes a more rigid interpretation. Good discussion on tax issues!
