I go through this ever year as well with my family. You basically have two options:
- Install TT on two different computers. I usually buy copy 1, and install it on my laptop, then have my spouse purchase copy 2, and install it on his laptop. We are then able to complete and efile everyone's taxes.
- You can complete all 9 tax filings using one copy of TT, but you can only e-file 5. Determine who of the 9 you can send via USPS versus e-filing, then mail those and e-file the others.
