I agree with Aunt Bea. I have always heard that municipal bonds are tax exempt. Debodun these days I trust online filing much more than I do mailing all that personal information. i've experienced too many glitches and mistakes by the postal service. Who's to say a postal employee won't open your envelope and use the information? They have been known to open envelopes that look like birthday and Christmas cards and take money out. If you file using a tax program that you installed...unless you have not secured your computer, you are the only person who sees the input. I don't know if a hacker could get in and see what you're doing IF you don't have a firewall, antivirus and malware. But everyone who uses a computer should have those things. Anyway, if you're filing using one of the online services, they guarantee security and should be safe as long as their URLs start with https:// Some sites have added the word Secure in front of that.
