Get your taxes done using TurboTax

FWIW, '/' is a perfectly valid XML character and should not trip up any XML parser. Only handful of entities require escaping and '/' isn't one of them. IRS OTOH might be running 1970's COBOL code so they may not have a real XML parser which is a separate issue. Regardless, I'm paying $275 for TT. TT should make sure your product works well with the IRS' electronic systems. Telling the user to print and mail their tax returns after paying $275 for it is a complete utter failure. Get better engineers and product managers. Next year I am using a real CPA.
