I liked that quote. Intuit being the biggest waste of money claiming direct filing is a waste of money. Like you said, FreeTaxUSA is at least reasonable.
Hard to argue that having a dozen companies developing IT software and systems to file taxes is more efficient them the organization that specifies the filing requirements do it once. The current system is more like a welfare program for the tax companies.
Many cell providers have a mail to SMS gateway. Just sent email to the correct address and you’ll get SMS. As far as sending mail either with bash or with Python. That is quite possible and not hard.
Sorry I do not have the code at hand. Memory is Python standard library has SMTP capability and Bash you can just use the mail command. May have to configure mail on your Linux box too or just use a remote server.
