Do online sellers (ebay, amazon, shopify) pay self-employment tax?
If you earn as an independent contractor, yes — self-employment tax is 15.3% (Social Security and Medicare) on your net profit, on top of regular income tax. You deduct half of it, and every business deduction lowers what you owe. We handle the calculation on Schedule SE.
What can online sellers (ebay, amazon, shopify) write off?
Common write-offs include cost of goods sold and inventory, platform and payment processing fees, shipping, packaging, and supplies, home office and storage space, plus a share of your phone and any home-office use. We go through your year line by line so nothing legitimate gets missed.
Do online sellers (ebay, amazon, shopify) need to pay quarterly estimated taxes?
If you expect to owe $1,000 or more for the year, the IRS generally wants quarterly estimated payments to avoid an underpayment penalty. We calculate them so next April isn't a surprise.
Do I have to report income if I didn't get a 1099?
Yes. Your income is taxable whether or not a client or platform sent a 1099. We report it correctly and offset it with every deduction you qualify for.
