The five federal e-files is an IRS limit. Buying another CD/download will not allow you to file more. If you have a big family and have already used up the 5 e-files, the other ones can be printed and filed by mail. When you mail a tax return, make sure to attach your W-2's or 1099's that show tax withheld. Use a mailing service like certified mail so you know it was received. Federal and state returns go in separate envelopes to separate addresses.
