Selling on Mercari

You would need to report the income on your tax return and pay the tax on it.

There are 2 ways to report the income.

1. If it is a hobby then the income is reported on schedule 1 for the full amount of the 1099 no expenses allowed to be taken

2. If it is a business then it would be reported on a schedule C (self-employed income). Yu would report the 1099 as income and then deduct the expenses you have against making that income.
