Amazon 1099-K: Why It Doesn't Match Your Deposits (And What To Do)

Every January, Amazon sellers open their 1099-K and have the same reaction: "I never received this much money." Correct. You didn't. The 1099-K reports gross payment volume, before Amazon's fees, refunds and adjustments. Your bank received what was left. Both numbers are right; they're just answering different questions.

What's actually in the 1099-K number

Box 1a is unadjusted gross sales processed through Amazon: product sales, shipping charged to buyers, gift wrap, and sales tax collected in some configurations. It does not subtract referral fees, FBA fees, storage, refunds, chargebacks, or advertising deducted from settlements.

A seller whose 1099-K says $487,000 might have had $28,000 in refunds, $73,000 in referral fees, $41,000 in FBA fees and $12,000 in ads netted from payouts, and banked around $333,000. That gap is normal. What matters is being able to show it.

Why the IRS cares

The IRS matches information returns against filed returns by computer. If Amazon says $487,000 gross and your Schedule C reports $340,000 of revenue because someone summed the deposits, the computer flags roughly $147,000 of "unreported income." The notice that follows (typically a CP2000) is resolvable, but it costs professional fees, months of correspondence, and occasionally a proposed tax bill computed as if the entire gap were profit.

The right way to report it

Report gross revenue that ties to the 1099-K, then deduct what Amazon kept:

• Gross sales: $487,000 (matches 1099-K, computer is happy)
• Returns and allowances: $28,000
• Amazon fees (referral, FBA, storage): $114,000 as expenses
• Advertising: $12,000

Same taxable profit as the "deposits" method when done right, zero mismatch. The catch: you can only produce these numbers from settlement reports, not from your bank feed. That's the whole argument for marketplace-aware bookkeeping.

Common 1099-K complications

Multiple marketplaces: Amazon issues per payment entity; eBay, Walmart, Etsy and PayPal each send their own. Every one needs to tie to your books individually. TikTok Shop's version arrives with creator commissions already netted from payouts (covered here), and creators paid through PayPal or Venmo hit the same gross-versus-net wall.

Sales tax in the gross figure: depending on configuration, facilitator-collected tax may appear in gross. Your books should show it as a pass-through liability, and your reconciliation should document the difference.

Mid-year business changes: switched from sole prop to LLC or changed bank accounts, and the 1099-K may span entities. Get bookkeeping help before filing, not after.

Personal account thresholds: the reporting threshold has dropped low enough that casual sellers get 1099-Ks now. Selling used personal items at a loss isn't taxable profit, but it still needs to be reported correctly to avoid the mismatch flag.

The five-minute self-check

Take last year's 1099-K. Open your filed Schedule C (or P&L). If gross receipts are within rounding distance of Box 1a, you're fine. If gross receipts look like your bank deposits instead, your filing method has a mismatch problem, and it's worth fixing the books before the IRS asks. That's a catch-up project, and it's much cheaper before the notice than after.
