I did not receive any income other than selling used items online or in person (for less than purchase value). No tax forms were received. I also was gifted money from relatives. Will I still need to file taxes? If so, how do I report?
The rules about the 1099-K forms are going to change for 2023 so you may get a form for next year if you sell more than $600 of personal items. At that point you would report that you sold the items for the same value as they cost and you won't owe any taxes on the money that you received.
For this year you don't have anything to report. Gifts are taxable to the person who gives them if they are over a certain value - not the person who receives them. And personal item sales aren't taxable so if you have no form that is showing those sales you have no requirement to report them. Sounds like you get to skip this year.
