Some MSCs pay a flat fee which includes the amount of required purchases. In those cases, I report the total amount (no choice if I earn enough to get a 1099), and then list the cost of the required purchases as reimbursed expenses / other expenses on Schedule C. That results in the reimbursed expenses being subtracted from my income. Easy to do. I use TurboTax and it walks me through the steps. I am sure that other tax preparation programs do so as well.
Other comments: The IRS requires a contemporaneous record of mileage. I record all of my trips in an Excel spreadsheet. In the same spreadsheet, I record the odometer reading on January 1 and on December 31. Averaged over 10 years, about 1/4 to 1/3 of my "income" is offset by mileage. This will vary from one person to another, but those of you who are not subtracting mileage are missing out an a large "deduction". I keep receipts for paper, ink, tape, etc.

I started shopping this year after a 15 year break. Do the 1099's include not just the shopper pay but the reimbursement amount? Reimbursement is not pay. If the latter than do you deduct the amount you spent at the shop such as the cost of a meal as an expense?
Shopping Southeast Pennsylvania, Delaware above the canal, and South Jersey since 2008
