publication 463 (Travel, Gift, and Car Expenses)

If you are are taking the expenses as unreimbursed partnership expenses, this publication will apply to you as well.  If your partnerships does have a reimbursement plan in place you can search Publication 535 for reimbursements (Chapter 11)

@MaryK1, my own LLC will reimburse me for car expenses related to business-use and issue Schedule K-1.  In publication 463, table 6-1 (page 31) summarizes reimbursements.  However, it refers to form W-2 which I don't receive (and form 2106 that I'm ineligible to file).  So how can my LLC reimburse its part-owner for car expenses under a non-accountable plan?  Thanks.
