...You shouldn't be getting 1099s for these reimbursements either, since they are pass-through.</font>
According to my sources, these reimbursements should be on a 1099-MISC if they go to a sole proprietor. The payor must report everything he/she/it paid you. Its being a pass-through on your return is out of their control, generally off their radar, and in any case in the future when the reimbursement is made and when the 1099-MISC is issued. You report the income, the offsetting deduction(s), and it's a wash.
If payment is to a corporation, there is no 1099 at all.
Reimbursed travel expenses are not reportable only for reimbursement of employees by their employer.
