You can't do that. The IRS has a limit of 5 e-filed returns unless you are a professional tax preparer, and it doesn't matter how many new copies of the software you install, you will not be permitted to e-file more than 5. To prepare more than five e-files, you will need to become an Authorized e-file Provider and register as an ERO (Electronic Returns Originator) with the IRS.http://www.irs.gov/Tax-Professionals/e-File-Providers-&-Partners/Become-an-Authorized-e-file-Provide...
Intuit has 2 products for tax preparers:

However, you can prepare, print and mail as many tax returns as you wish.
