You cannot take any expenses if the income is claimed as hobby income. For an IRS resource, see: Hobby or Business Guidance
However, you should determine how you want to treat this revenue. I could argue a hobby generating a lot of revenue could be considered a trade or business. If it is decided going forward to treat it like a business, then include expenses when reporting it as self-employed income on Schedule C. For more details, see: Am I considered self-employed?
For reporting Form 1009-K for personal items sold not associated with a trade or business, you have two options:
- Option 1 in TurboTax Premier or higher: reporting Form 1099-K as investment income
- Go to the search box and enter Investment Sales
- Select Jump to Investment Sales
- Select Other at the next screen, OK, what type of investments did you sell? and click Continue
- At Tell us more about this sale, enter in the name, such as Form 1099-K Personal Property Sales and the Payer's EIN and click Continue
- At Now we'll walk you through entering your sale details, under the first dropdown menu, What type of investment did you sell? Select Personal Items
- Answer How did you receive this investment with an option from the dropdown menu.
- Enter the Description. If you are uncertain what date you purchased the goods, select Something other than a date so that TurboTax will enter Various
- Next, enter your Sale Proceeds and an equal amount for the Total Amount Paid and click Continue. The description for the cost should include Cost of Personal Property
- Select None of these apply at Let us know if any of these situations apply to this sale and Continue
- Continue through the rest of the prompts
- Select Add another sale to add the next Form received
- Option 2 in TurboTax Deluxe or higher: reporting it via Other Miscellaneous Income is acceptable to the IRS.
- From the left menu, go to Federal and select the first tab, Wages & Income
- Add more income by scrolling down to the last option, Less Common Income, and Show more
- Scroll down to the last option, Miscellaneous Income, 1099-A, 1099-C and Start
- Choose the last option, Other reportable income and Start and Yes
- Enter the applicable description and amount and Continue
- First, enter Form 1099-K as received. It is essential that the full amount be entered.
- For a description, include Form 1099-K and Personal Property Sales
- Next, enter an adjustment to reflect the cost of these items as an offsetting, negative amount up to the amount of the income.
- For the cost description, include Form 1099-K and Cost of Personal Property
- In other words, if the goods cost you $100 and Form 1099-K was for $10 in sales, the maximum cost allowable would be $10.
