Amazon sellers generally pay tax on their net business profit, rather than the total amount Amazon pays into their bank account. To calculate taxable profit, take your gross sales and subtract allowable business expenses, such as refunds, cost of goods sold, Amazon and FBA fees, advertising, shipping, and other ordinary business costs.<\/p>\n\n\n\n
Imagine Sarah, who started selling home decor items through Amazon. She believed the $120,000 in annual sales shown on her Seller Central dashboard was comparable to her earnings. At tax time she learned otherwise: her real earnings had been reshaped by Amazon referral fees, FBA storage fees, returns, refunds, PPC advertising, shipping, and inventory purchases.<\/p>\n\n\n\n
The problem was not that Sarah had failed to make sales. She had made strong sales. The problem was that she had not tracked where the money went. With accurate bookkeeping and a clear understanding of Amazon seller taxes, she could separate gross sales from real profit, support eligible deductions, and avoid unexpected tax bills.<\/p>\n\n\n\n
This guide outlines how Amazon seller taxes work in 2026, what documentation to maintain, what expenses might be deductible, roughly how much tax to expect, and how to be ready for tax season.<\/p>\n\n\n\n
Amazon seller taxes cover the federal, state, and local taxes on income from selling on Amazon, including federal income tax, self-employment tax, and state-level requirements. Amazon may handle sales tax collection on many marketplace sales, but sellers are still responsible for accurately reporting business income.<\/p>\n\n\n\n
Yes. Even if Amazon does not send you a tax form, you generally must report your company income if you run a profitable Amazon business in the US. What you owe depends on profit, business structure, total revenue, location, and applicable state laws.<\/p>\n\n\n\n
Taxable Amazon business profit, after qualifying deductions, is subject to federal income tax at your marginal rate, which currently ranges from 10% to 37% by income and filing status. You may owe nothing if deductions, credits, and losses bring your liability to zero.<\/p>\n\n\n\n
If you have net self-employment earnings of $400 or more as a sole proprietor, partner, or certain LLC owner, you generally owe self-employment tax of 15.3% (12.4% Social Security, 2.9% Medicare), calculated on 92.35% of net profit. This funds Social Security and Medicare, on top of income tax, and is one of the biggest surprises for first-year sellers.<\/p>\n\n\n\n
There is no single flat rate: your bill blends self-employment tax with your federal bracket, plus any state income tax. Many self-employed sellers budget 25% to 30% of net profit for combined federal taxes. On the $25,000 net profit used later in this guide, self-employment tax alone runs about $3,533 ($25,000 \u00d7 92.35% \u00d7 15.3%), before income tax is added. A tax professional or the IRS Tax Withholding Estimator can give you a precise figure.<\/p>\n\n\n\n
Where marketplace facilitator laws apply, Amazon typically collects and remits sales tax on qualifying sales. You may still need to register, file returns, or report sales, especially if you also sell through your own website or other channels.<\/p>\n\n\n\n
Depending on where you’re registered, have workers, keep inventory, or operate, you may owe state income tax, franchise tax, gross receipts tax, annual business fees, or local business licenses. Requirements vary by state and city, so check local rules directly.<\/p>\n\n\n\n
Amazon issues Form 1099-K once sales reach the IRS reporting threshold. Following the One Big Beautiful Bill Act (OBBBA), the federal threshold is back to more than $20,000 in gross payments and more than 200 transactions a year, reversing the phased-in $600 rule. A few states, including Massachusetts, Vermont, Virginia, and New Jersey, still enforce lower thresholds, so you can receive a 1099-K below the federal limit. Either way, you must generally disclose taxable income even without this form.<\/p>\n\n\n\n
The 1099-K reports gross payment volume, not profit, and Amazon sends a matching copy to the IRS. If your Schedule C net income looks very different from the 1099-K gross figure, the IRS may send a CP2000 notice asking you to explain the gap. Keep a simple reconciliation, 1099-K gross sales minus COGS, Amazon and FBA fees, refunds, and shipping, so it ties out to your Schedule C profit.<\/p>\n\n\n\n
Sales tax is generally set by the shipping address, product category, and local or state law. A customer orders; the delivery address, not the seller’s residence, determines the tax. Amazon calculates the tax at checkout, collects it from the buyer along with taxable shipping charges, and remits it to the state under marketplace-facilitator laws; this amount is not part of your income. Amazon then pays you the remainder, after referral fees, FBA fees, storage fees, refunds, and advertising costs.<\/p>\n\n\n\n
Sales tax nexus. Beyond marketplace collection, FBA sellers can have a “sales tax nexus”, a legal obligation to register and file in a state, created by physical presence (inventory in that state’s fulfillment centers) or economic nexus, which most states trigger once sales into that state cross roughly $100,000 a year (thresholds vary). Amazon collecting tax at checkout doesn’t automatically satisfy every state’s filing requirement, so sellers with inventory across multiple fulfillment centers should confirm registration state by state, ideally with a sales-tax automation tool or a tax professional.<\/p>\n\n\n\n
Sellers should still keep sales-tax reports, monitor inventory storage locations, and track sales through their own website, wholesale accounts, or other channels, even where Amazon manages collection.<\/p>\n\n\n\n
