Amazon tax works on two tracks. If you’re buying, Amazon calculates the correct combined state and local sales tax based on your shipping address and sends it to the government for you, so nothing else is required on your end. If you’re selling, Amazon also collects and remits the sales tax on your marketplace orders, but you still owe federal and state income tax on your profits, self-employment tax if you’re a sole proprietor or partner, and you’re responsible for making quarterly estimated payments on your own.
What Buyers Pay at Checkout
Sales tax on an Amazon order is set by your shipping address. Amazon applies the combined rate for your city, county, and state, so two buyers in the same state living a few miles apart can see different tax amounts on identical orders. The tax line appears after coupons and discounts are applied to the item price.
Five states have no statewide sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. Orders shipped to those states typically show zero tax at checkout. Alaska is a partial exception, because some local jurisdictions there impose their own sales taxes and Amazon’s handling of those varies. Everywhere else, expect a tax line, and expect Amazon to handle filing and payment to the state on your behalf.
Why the Tax Amount Changes With What You Buy
Not everything is taxed at the same rate, and some items aren’t taxed at all depending on where they’re going. Most states exempt prescription drugs. Many exempt unprepared groceries, though the definitions matter: some states tax candy and soft drinks at the full rate while exempting bread and milk. Arkansas and Illinois recently repealed their state-level grocery taxes, though local taxes may still apply.
Clothing is fully exempt in a handful of states and exempt below a set dollar threshold in others. Digital goods like e-books, streaming subscriptions, and downloaded software are treated inconsistently: some states tax them exactly like physical items, others exempt them entirely. Federal law prohibits states from taxing internet access itself, but products and services bought online are otherwise fair game.
Amazon’s tax engine bakes these rules in. When you buy a bag of rice shipped to a state that exempts groceries, the system should apply zero tax on that item automatically. The result: your total depends on both what you’re buying and where it’s being delivered.
Why Sellers No Longer Collect Sales Tax Themselves
Before 2018, an online business only had to collect sales tax in states where it had a physical presence. The Supreme Court’s decision in South Dakota v. Wayfair overturned that, holding that economic activity alone can create enough connection to require tax collection, even without any physical footprint in the state.1Supreme Court of the United States. South Dakota v. Wayfair, Inc.
States moved fast. All 45 states with a sales tax, plus Washington, D.C., now have marketplace facilitator laws that shift the collection obligation from individual sellers to the platform. Amazon is legally responsible for calculating, collecting, and remitting sales tax on virtually every third-party sale made through its marketplace. A seller with customers in 30 states no longer needs to register, file, and remit in all 30 for Amazon orders.
The important boundary: marketplace facilitator laws only cover sales made through the platform. If you also sell through your own website, another marketplace, or in person, you’re personally responsible for sales tax in any state where you’ve hit economic nexus. Most states set that threshold at $100,000 in sales or 200 transactions during the year, though some use different figures. Cities and counties in home-rule states like Colorado, Alabama, and Alaska can also set their own rules and registration requirements independent of the state, which can mean separate local filings for sellers with direct sales channels.
The 1099-K and What It Actually Shows
Amazon reports sellers’ gross payments to the IRS using Form 1099-K. The reporting threshold bounced around for several years, but the One, Big, Beautiful Bill Act restored the pre-2021 standard: Amazon is required to file a 1099-K only when a seller’s gross payments exceed $20,000 and the seller has more than 200 transactions in a calendar year.2Internal Revenue Service. IRS Issues FAQs on Form 1099-K Threshold Under the One, Big, Beautiful Bill Both conditions must be met.
Falling below the threshold doesn’t make your earnings tax-free. The 1099-K is an information return, and the IRS expects all business income to be reported on your tax return whether or not you receive one.
What trips up new sellers: the 1099-K shows gross sales, not profit. It includes the full amount buyers paid, before Amazon fees, refunds, shipping costs, and the cost of the products themselves. If your 1099-K says $45,000 but your actual profit after expenses was $12,000, you’re taxed on the $12,000, but you need records to prove that gap.3Internal Revenue Service. Form 1099-K FAQs: What to Do if You Receive a Form 1099-K
Deductions That Turn Gross Sales Into Taxable Profit
Sole proprietors report Amazon income and expenses on Schedule C. The categories that matter most for closing the gap between the 1099-K figure and what you actually owe:
- Cost of goods sold: what you paid for inventory, including wholesale prices, manufacturing costs, and inbound shipping to Amazon’s warehouses.
- Amazon fees: referral fees, FBA fulfillment and storage fees, and monthly Professional seller account subscriptions.
- Shipping and packaging: outbound shipping charges, boxes, poly mailers, labels, and freight expenses.
- Advertising: Amazon PPC campaigns, sponsored product ads, and off-platform marketing.
- Software and tools: inventory management, repricing tools, accounting software, and keyword research subscriptions.
- Home office: if you use a dedicated space exclusively for the business, a proportional share of rent, utilities, and insurance, or the simplified method at $5 per square foot up to 300 square feet.
- Professional services: bookkeeping, tax preparation, and legal fees related to the business.
Records aren’t optional. Download your Amazon settlement reports regularly and reconcile them against your own books. Waiting until April to sort through a year of transactions is where expensive mistakes happen.
Self-Employment Tax
This is the cost that blindsides most new Amazon sellers. If you operate as a sole proprietor or partnership, your net business profit is subject to self-employment tax on top of regular income tax. Self-employment tax covers Social Security and Medicare, the same payroll taxes an employer would withhold and match, except you pay both halves yourself.
The combined rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare.4Office of the Law Revision Counsel. 26 USC 1401 – Rate of Tax The Social Security portion only applies to the first $184,500 in net earnings for 2026.5Social Security Administration. Contribution and Benefit Base Above that cap, you still owe the 2.9% Medicare tax on all earnings. If self-employment income exceeds $200,000 as a single filer or $250,000 filing jointly, an additional 0.9% Medicare surtax applies to the excess.
There’s a partial offset: you can deduct half of your self-employment tax when calculating adjusted gross income.6Internal Revenue Service. Topic No. 554, Self-Employment Tax This doesn’t reduce the self-employment tax itself, but it lowers the income used to calculate your income tax.
The practical impact is substantial. A seller with $60,000 in net profit owes roughly $8,478 in self-employment tax alone, before income tax. Sellers organized as S-corporations can reduce this burden by paying themselves a reasonable salary and taking remaining profits as distributions not subject to self-employment tax. That structure adds accounting and payroll costs, so it generally only makes sense once profits consistently exceed $40,000 to $50,000 per year.
Quarterly Estimated Payments
Amazon doesn’t withhold income tax or self-employment tax from your disbursements. You pay those yourself throughout the year. The IRS requires quarterly estimated payments if you expect to owe $1,000 or more in tax for the year after subtracting any withholding from other income sources and refundable credits.7Internal Revenue Service. Estimated Tax for Individuals (Form 1040-ES)
The four payment deadlines for 2026:8Internal Revenue Service. Estimated Tax
- April 15, covering income earned January through March.
- June 15, covering April through May.
- September 15, covering June through August.
- January 15, 2027, covering September through December.
Missing these deadlines triggers an underpayment penalty that functions like interest, currently 7% per year and compounded daily.9Internal Revenue Service. Interest Rates Remain the Same for the First Quarter of 2026 The penalty accrues from each missed quarterly due date, not just at filing time.
Two safe harbors keep you out of trouble: pay at least 90% of your current-year tax liability through quarterly payments, or pay 100% of what you owed last year. If your adjusted gross income last year exceeded $150,000, the prior-year safe harbor increases to 110%.7Internal Revenue Service. Estimated Tax for Individuals (Form 1040-ES) New sellers with no prior-year history should estimate conservatively and adjust each quarter as actual sales come in.
The FBA Inventory Wrinkle
Fulfillment by Amazon causes a tax issue that catches sellers off guard. When you ship inventory into Amazon’s network, Amazon distributes it across warehouses in multiple states to speed up delivery. Each state where your inventory sits can treat you as having a physical presence there, even if you’ve never set foot in that state.
Marketplace facilitator laws mostly neutralize the sales tax side, because Amazon collects and remits regardless of where inventory is stored. But physical nexus from FBA inventory can trigger other obligations. Some states require corporate or franchise tax returns if you have property located there. A handful impose personal property taxes on inventory stored within their borders. Treatment varies: some states fully exempt inventory held for resale, others tax it at the same rates applied to any other business property. Sellers with large FBA footprints across many states should check whether they have filing obligations beyond sales tax.
If You Sell Internationally
Selling across borders brings in consumption taxes that work differently from US sales tax. Most countries outside the US use Value Added Tax or Goods and Services Tax, collected at every stage of the supply chain rather than only at the final sale.
For sales into the European Union, Amazon acts as the deemed supplier on imported shipments valued at €150 or less, collecting VAT at checkout and remitting it through the Import One Stop Shop. For shipments above €150, or for goods stored in Amazon’s European fulfillment centers, sellers typically need their own VAT registration in each country where they hold inventory. Beginning in 2026, the EU is also eliminating the €150 customs duty exemption for e-commerce parcels, meaning goods that previously entered duty-free will face customs duties on top of VAT.10European Commission. E-Commerce: 150 EUR Customs Duty Exemption Threshold to Be Removed as of 2026
Similar marketplace collection rules apply in countries with GST systems like Australia and Canada. Amazon generally handles GST collection on marketplace sales into those countries, but sellers with inventory or a business establishment there should verify their local registration obligations independently.
