I didn't see this answered by the incredibly thorough tax topic that is stickied to this forum, but am trying to figure out in advance what my tax implications might be for this year, I just started mystery shopping in January. I've done several reimbursement only restaurant shops as otherwise our eating out budget would be tiny. If I spend $50 and only $35 is reimbursed, is the $15 non-reimbursed business expenses? I could have stayed under the $35, but we also wouldn't have gone to the restaurant if we hadn't been reimbursed the $35. I realize some of the time when I go over a reimbursement amount I can't claim the overage as non-reimbursed business expenses like for a gas station shop or a grocery store shop, but this is a bit different. Thanks in advance!
