How to report a personal expense for an LLC partnership paid in one year and reimbursed in another?
You report it when the expense was incurred/accrued. Which is, in your case, 2014. There's no such thing as "accounts payable" on tax forms, it is an account on balance sheet, but most likely it is irrelevant for you since your LLC is probably cash-based. The reimbursement is a red-herring, what matters is when you paid the money.
