If you don't know, the answer is prbloaby that you didn't.The 1065 is a complete tax return with k-1s attached. It's filed separately from your personal taxes and you use your copy of the k-1 to prepare your return. (Look at your taxes, was there anything on line 17? The k-1 goes to schedule E, which then goes to line 17.)Yes, you can file now for 2008 if you need to. Attach a letter and beg and see if they will waive the penalties for not filing. (The penalties are SEVERE. You are 10 months late and the penalty is $89 a month PER member for up to 12 months.)If you didn't file and the K-1 shows income, you then need to amend each individual tax return.PS, was this husband/wife? Did you accidentally report the income on schedule C? If you did, the damage to your personal return may be slight that is, the income made it to the return, but on the wrong forms.
