Your eBay 1099-K shows gross sales. Your actual taxable profit is much lower. This calculator shows the real number — COGS, fees, shipping, and all.

Deductible expenses
Tax estimate
You owe tax on $6,289, not $15,000
Your 1099-K shows $15,000 in gross sales, but after deducting COGS ($5,000), eBay fees ($2,012), shipping, packaging, and other expenses, your actual taxable profit is $6,289 — a difference of $8,712.
Deduction breakdown
Why reinvesting in inventory doesn't reduce your tax the way you think
Buying more inventory reduces your future taxable income — but only when you sell it. Under the cash method of accounting, COGS is deducted in the year items are sold, not when purchased. Items still in your garage are an asset, not a deduction yet.
