what is a 1099 form

What a 1099 form actually is

A 1099 is a family of IRS information returns used to report payments made to you by someone other than an employer. Instead of a W-2, businesses and platforms that pay you use various 1099 versions depending on the type of income — 1099-NEC for contractor payments, 1099-MISC for things like rent or royalties, and 1099-K for payments processed through a third-party settlement network, which is the one that applies to most Amazon sellers.

The key thing to understand: the IRS gets a copy of every 1099 issued to you. If the income you report on your tax return doesn't line up with what's on file, that's a fast track to a mismatch notice. Amazon sellers who also sell on Etsy, Walmart, or eBay may get a separate 1099-K from each platform, and all of them need to be accounted for in your books.

Form 1099-K and Amazon sellers, specifically

Amazon issues Form 1099-K to report the gross unadjusted payment volume processed through your seller account — meaning the total dollar amount of sales before Amazon fees, refunds, shipping costs, or advertising spend are subtracted. That's a critical distinction: the number on your 1099-K is almost always much higher than your actual taxable profit.

The reporting threshold for who receives a 1099-K has been a moving target. The IRS 1099-K reporting threshold for third-party platforms has been changing in recent years and is being phased rather than fixed at the old $20,000/200-transaction level, so don't assume last year's cutoff still applies — check the current IRS guidance for the tax year you're filing. In practice, most active Amazon sellers get one regardless of the exact threshold, since gross sales volume adds up fast.

Because the 1099-K reflects gross receipts, your accounting has to bridge the gap between that figure and net profit. That means capturing Amazon's referral fees, FBA fees, advertising, returns, and reimbursements as separate line items rather than lumping everything into one "Amazon deposit" entry.

Why the gross number on your 1099-K isn't your profit

A common seller mistake is treating the 1099-K total as taxable income and panicking at the size of the number, or worse, reporting it as-is without backing out expenses. Neither is correct. Your actual taxable income is gross sales minus cost of goods sold, Amazon fees, shipping, advertising, software subscriptions, and other ordinary business expenses.

This is where clean books matter more than the tax form itself. If your bookkeeping treats Amazon as a single bank feed transaction, you lose the fee-level detail needed to defend your numbers if the IRS ever asks why your reported income is lower than your 1099-K total. Structuring transactions properly in Amazon accounting in QuickBooks & Xero — separating gross sales, fees, refunds, and reimbursements — is what lets you reconcile confidently instead of guessing.

This gap has grown more relevant as third-party selling has scaled: third-party sellers now account for more than half of the physical gross merchandise sold on Amazon, meaning far more individual sellers are now generating 1099-K-level payment volume than in Amazon's early years, and far more of them need to understand this distinction.

1099s, sales tax, and other reporting sellers confuse

Sellers sometimes conflate income tax reporting (1099-K) with sales tax collection, but they're separate systems. Since the Supreme Court's Wayfair decision, states can require sellers to collect sales tax based on economic nexus rather than physical presence, and nearly all states with a sales tax now have marketplace facilitator laws that shift the collect-and-remit duty onto Amazon itself for marketplace sales. That means Amazon is generally handling sales tax collection on your behalf — but it has nothing to do with the income figures on your 1099-K, which are strictly about federal income reporting.

Keeping these threads separate — income tax via 1099-K, sales tax via marketplace facilitator rules, and inventory-related items like FBA reimbursements — avoids the mixed-up bookkeeping that causes most year-end filing headaches.

Frequently asked questions

Does Amazon send my 1099-K to the IRS too?

Yes. Amazon files a copy of your 1099-K with the IRS in addition to sending it to you, so the gross payment figure is already on record before you file. Your reported business income doesn't need to match that number exactly, but you should be able to explain the difference with your expense records.

What if I sell on Amazon and another platform?

You'll likely receive a separate 1099-K from each platform that meets the reporting threshold, such as Amazon, Etsy, or Walmart. Add all of them together as part of your total gross receipts, then apply the same expense-and-fee breakdown to each before calculating net taxable income.

Is FBA reimbursement income reported on my 1099-K?

Reimbursements for lost or damaged inventory usually flow through your Amazon payment account, so they can show up in your gross settlement totals. Note that since 2025 Amazon reimburses based on your manufacturing/sourcing cost rather than retail price, so these amounts are typically smaller than sellers expect and should be tracked separately from sales revenue in your books.

I didn't get a 1099-K — do I still owe taxes on my Amazon income?

Yes. The 1099-K threshold only determines whether Amazon is required to send you the form; it doesn't determine whether you owe tax. All business income is reportable regardless of whether a 1099 was issued.

Why is my 1099-K amount so much higher than what I actually made?

Because it reports gross unadjusted payment volume — total sales before Amazon fees, refunds, shipping, and ad spend are deducted. Your actual profit is calculated separately once those business expenses are subtracted, which is why detailed, fee-level bookkeeping matters at tax time.
