<prompt> Human: So ive been selling some stuff around my house and a lot of stuff i find in thrift stores and in the junk yard on Ebay, I estimate that i will be making about 9000 a year off this which really helps me because i only make about 20k a year on my normal job. My question is how much can i make in paypal before i have to file taxes on it? Is there a limit to how much i can make before the IRS says woah wheres all this coming from and wheres our cut? or will i have to file taxes on it no mater how much i make?  <response>: Unless otherwise exempted, all income is taxable theres no floor. So 1 for income taxes, and 400 for self employment taxes With 10k in taxable income from your other job, expect 15 for income taxes and 14 for self employment, so save 30state for every dollar of profit you make.Since PayPal is a payment provider and not your client, their 1099-K is only required to be issued for 20,000 in payments or 200 transactions but no report doesnt alleviate your responsibility to pay.And remember youre taxed on profit and gains, not revenue. So subtract out costs of selling, ads, shipping, and original purchase prices. Theres also capital gains vs income, especially for your around the house stuff.So in addition to the 1040, youll file a Schedule C and Schedule SE. If theres no receipt for your yardsale stuff, thats fine, just keep records if youre ever audited.
