If you are not going to charge for the return preparation, I believe you can use Turbotax. the problem is the return limitation imposed by thre IRS. with deesktop you can prepare up to 5 returns that can be e-filed. buying another license to do more will not work so you are probably . for onlie you need a separate a/c for each return so you don't overwrite one prepared earlier. the same 5 return limiation applies.
