Deluxe will handle 5 federal emails. The IRS limits you to five efilings. They do this so that unregistered preparers who charge their customers have a harder time using programs like TT for their nefarious dealings.
The IRS imposes a limit of 5 e-mail returns. Preparing greater than 5 returns is viewed by the IRS as being 'a preparer' and requires registration with the IRS. It is NOT a TurboTax limitation, and it does not matter how many TurboTax packages you buy; if you try to e-file more than 5 returns you should consider it an invitation to the IRS to contact you.
NOTE: 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, see:

Intuit has 2 products for tax preparers:

However; while you can only e-file 5 returns, the TurboTax software will let you PRINT and MAIL as many additional copies as you need at NO additional charge for the federal returns.
