Amazon Seller Taxes: Sales Tax on Amazon and What You Owe in 2026

Do Amazon sellers pay taxes? Yes, on profit, like any business. But Amazon selling has three tax layers that confuse people because they work completely differently: income tax, sales tax, and the 1099-K information return that ties them together. Here's each one, plainly.

Layer 1: Income tax on your profit

You owe federal (and usually state) income tax on net profit: revenue minus cost of goods sold minus expenses. Sole proprietors and single-member LLCs report it on Schedule C; the profit also picks up 15.3% self-employment tax. S-corps and partnerships file their own returns and pass income through.

The part sellers get wrong isn't the form, it's the inputs. Your revenue is your gross sales, not your deposits. Your COGS is the cost of inventory you sold, not inventory you bought. Get those two right and the rest is arithmetic. Get them wrong and you're either overpaying tax or filing a return that contradicts the 1099-K Amazon sent the IRS.

Layer 2: Sales tax (mostly Amazon's job now)

Marketplace facilitator laws in every sales-tax state make Amazon collect and remit sales tax on marketplace orders. For most FBA sellers, that part is genuinely handled.

What's still yours:

• Direct-channel sales. Your Shopify store's sales tax is your responsibility wherever you have nexus.
• Registration obligations. Some states still expect registered sellers to file returns (often zero-due) even when Amazon remits.
• Nexus from FBA inventory. Amazon placing your inventory in a state's warehouse can create physical nexus there. It matters mainly if you also sell direct.
• Bookkeeping hygiene. Tax that flows through your account must sit in a liability account, not revenue. Booked as revenue, it inflates your sales and your tax bill.

The state-by-state details vary more than sellers expect. Washington bills you a gross-receipts B&O tax even when Amazon collects everything, while Florida ignores your marketplace volume entirely and has a surtax cap most rate calculators miss. If you ship into either state, those two guides are worth ten minutes.

Is there sales tax on Amazon, and what rate does Amazon charge?

Yes. Every order shipped to a state with a sales tax gets taxed at checkout, and Amazon's tax engine sets the rate, not you. The rate is the buyer's destination rate: the state rate plus any county, city and district add-ons for the delivery address. That's why the rate runs from 0% in the states with no statewide sales tax (Alaska, Delaware, Montana, New Hampshire and Oregon) to more than 10% in parts of Louisiana, Tennessee and Washington. A $100 order to Chicago carries about $10.25 of tax. The same order to Portland carries none.

Sellers don't pick the rate. What you do control is the product tax code on each listing. Groceries, clothing, supplements and digital goods are taxed differently from state to state, and a listing left on the generic "always taxable" code over-collects on a product that's exempt in New Jersey or Pennsylvania. Amazon remits whatever it collected either way, so the cost of a wrong code lands on your conversion rate rather than your bank account.

The line on an Amazon order page that reads "estimated tax to be collected" is this same destination-rate calculation, shown before the order finalizes. It's labeled estimated because the final figure locks when the item ships, and it can move a few cents if part of the order ships separately or a promotion applies after checkout. On your side, that number lands in the settlement report as tax collected and, one line later, as tax withheld by Amazon as the marketplace facilitator. Net effect on your bank account: zero. Net effect on your books: also zero, as long as neither line gets posted to revenue.

How much tax does Amazon charge you, the seller? On product sales, nothing. The buyer pays it, Amazon collects it and remits it. Your settlement report shows the collected tax passing through, which is why it must never land in your revenue account. Amazon's own fees, referral and FBA, aren't taxes at all; they're deductible expenses. In a few states Amazon does add sales tax to certain seller fees, and if a tax-on-fees line shows up in your settlement, book it as an expense, not as collected tax.

Layer 3: The 1099-K, where returns go to die

Amazon reports your gross payment volume to the IRS on Form 1099-K. Gross means before fees, refunds, and everything else. Your bank deposits are net. The gap between them is routinely 25-35% of gross.

If your return shows revenue that looks like your deposits, the IRS computer sees a mismatch against the 1099-K. Mismatches generate notices. The fix is books built from settlement reports, where gross sales tie to the 1099-K and fees are deducted as expenses. Same tax owed, no letter. The trap isn't Amazon-specific either: TikTok Shop sellers and content creators paid through payment platforms get the same gross-figure 1099-Ks.

Deductions Amazon sellers commonly miss

• Amazon's fee zoo: referral, FBA fulfillment, storage, long-term storage, removal fees. All deductible, all invisible if you book net deposits.
• Ad spend (Sponsored Products et al.), often netted out of settlements and never surfaced.
• Inventory shrinkage: lost and damaged units Amazon didn't reimburse. Our FBA reimbursement guide covers how to claim them before the window closes.
• Home office, mileage to source inventory, software subscriptions, education. Ordinary rules, commonly skipped.
• Reimbursements handled backwards: Amazon lost-inventory reimbursements aren't revenue windfalls; they offset inventory losses.

Quarterly estimated taxes

Profitable sellers generally owe quarterly estimates (April, June, September, January). The safe-harbor rule of paying 100% of last year's tax (110% for higher incomes) avoids penalties even if you're growing. This is the single easiest tax problem to prevent and the most common one new sellers hit.

Non-US sellers on Amazon.com

Different rulebook entirely: W-8 forms in the tax interview, Form 5472 for foreign-owned LLCs (a $25,000 penalty if skipped), and treaty questions about whether US income tax applies at all. We cover it on our international sellers page.

What to do before year end

Reconcile your books to your settlement reports, count or value your inventory as of December 31, pull your annual 1099-K when it drops, and hand your CPA a file where those three things agree. If they don't agree, fix the books before filing, not after the letter. That's the service we provide, starting with a catch-up if you're behind.
