The Amazon Tax Document Library is the section of Seller Central holding your tax-related documents: sales tax reports, Form 1099-K where issued, and invoices and credit notes for Amazon’s fees. You reach it through Reports, then Tax Document Library.
It is a filing cabinet rather than an accounting system, and that distinction matters more than most guides admit. It tells you what Amazon collected and charged. It does not tell you what you owe.
This is general information for sellers, not tax advice. Tax rules for marketplace sellers change frequently, vary by state, and depend on facts specific to your business. A CPA who works with ecommerce sellers is worth considerably more than any article, this one included. We handle account operations for sellers as an Amazon SPN Verified Partner, and we hand the tax questions to accountants.
What is in the Amazon Tax Document Library
Sales tax reports. Transaction-level detail, broken down by jurisdiction. Amazon splits these three ways by who was responsible for collection, and the split matters more than it looks.
Form 1099-K. The information return reporting your gross transactions to the IRS. Issued when you meet the applicable threshold. See below, because this is where the confusion lives.
Fee invoices and credit notes. Documentation for referral fees, FBA fees, subscription charges, and adjustments. These are your deductible expense records, and I’ve found them genuinely useful beyond tax season for spotting fee changes nobody announced.
Filter by document type and date range, download what you need, and keep your own copies. I’d archive these monthly rather than relying on Amazon’s retention, since access to historical records is not guaranteed indefinitely.
The 1099-K threshold, honestly
Read this part slowly. The rule has changed several times in recent years, a great deal of published guidance is stale, and the version you find in a search result may describe a threshold that applied to a tax year you are not filing for.
The long-standing federal threshold for third party settlement organizations was $20,000 in gross payments and 200 transactions. Legislation then lowered it substantially, the IRS delayed implementation and applied transitional thresholds for interim years, and subsequent legislation in 2025 restored the higher threshold.
The practical consequences for a seller:
Check the rule for the specific tax year in question. One number does not cover everything here. A form issued for one year may have been generated under an entirely different threshold from the one that applied twelve months later, which is why sellers comparing two years of paperwork sometimes conclude Amazon made a mistake when nothing went wrong at all.
Several states set their own, lower thresholds. A number of states require reporting well below the federal figure, some at a few hundred or a few thousand dollars. If you have received a 1099-K while apparently sitting under the federal threshold, this is usually why.
Not receiving a 1099-K does not mean the income is not reportable. This is the point that actually matters and the one most articles bury. Your obligation to report income does not depend on whether a form was issued. The form is an information return to the IRS, not a definition of taxable income.
The gross figure will not match your bank deposits. A 1099-K reports gross transactions before Amazon’s fees, before refunds, and before returns. Your accountant reconciles from there. In my experience the gap alarms first-time sellers every year, and it is expected rather than an error.
Given how much this has moved, confirm the current position with the IRS or your accountant rather than any article.
What marketplace facilitator laws changed
This is the second area where older guidance misleads.
Every US state with a sales tax now has marketplace facilitator legislation requiring the marketplace, rather than the individual seller, to collect and remit sales tax on marketplace sales. Amazon collects and remits on your Amazon sales in those states.
That removed a large administrative burden. It did not remove every obligation, and three things still sit with you:
Sales through other channels. Your own website. Wholesale. Any channel where no facilitator collects on your behalf. Those obligations remain entirely yours, and sellers who moved onto Shopify after years of Amazon-only trading are the ones most likely to be caught out by a rule they had genuinely never needed to think about.
Registration and filing requirements. Some states still expect a registered seller to file returns reporting marketplace sales even where Amazon remitted the tax. Whether it applies to you depends on the state. Ask before assuming it does not.
Income and franchise tax. Different systems entirely. FBA inventory stored in a state has been argued to create income or franchise tax obligations there, states take differing positions on whether that argument holds, and the answer can turn on facts as specific as how long a unit sat in which warehouse. Ask a professional.
An important correction on nexus
Older guidance on this topic, including the previous version of this article, suggested that shipping a couple of hundred items into a state establishes nexus there. That is not how it works and the example was wrong.
We tested the old advice against actual state rules while updating this piece and it did not survive. Two things to know:
Economic nexus thresholds are set by each state and vary considerably. Many are based on sales revenue alone. California’s economic nexus threshold, for instance, is based on a substantial sales figure with no transaction count, so a few hundred orders establishes nothing on its own. Several states that originally included a transaction-count test have since removed it.
Marketplace sales are usually counted differently anyway. Because Amazon collects and remits as the facilitator, marketplace sales do not create the same collection obligation for you that direct sales would, though states differ on whether those sales count toward your thresholds at all.
The honest summary: nexus is state-specific, fact-specific, and changes. Do not determine it from a blog post. Determine it with an accountant who can see your actual sales by state and by channel, because that is the only view from which the question can be answered correctly rather than approximately.
Why the reports separate seller and Amazon liability
The three-way split in the sales tax reports confuses people, and understanding why it exists makes the reports far more useful.
Amazon-collected tax is money Amazon took from the buyer and remits itself under facilitator legislation. You never touch it, and it appears in your reports so you can evidence it, not so you can act on it.
Seller-responsible tax covers the narrowing set of situations where the obligation sat with you rather than the marketplace. For most sellers on most sales this column is now empty, which is a genuine improvement on how things worked before facilitator laws.
The combined view is what your accountant usually wants, because it shows the total picture per jurisdiction regardless of who handled it.
The reason to care: a state authority asking questions wants to see jurisdiction-level evidence, and reconstructing it later from order data is miserable. Downloading it monthly costs nothing and answers the question in advance.
What the library does not do
Worth being clear, because sellers over-rely on it.
It is not bookkeeping. It holds documents. That is all. Cost of goods, inventory value, and profit live nowhere in it, which means a seller relying on the library alone at year end will discover that the hardest numbers in their return are the ones nobody was tracking.
It does not calculate what you owe. Not even approximately. Income tax and any residual sales tax obligation both require work that happens well outside Seller Central.
It does not cover other channels. Walmart, Shopify, eBay, TikTok Shop. Those records live elsewhere entirely, and consolidating them is the job the library cannot do.
It does not replace an accountant. Ecommerce tax involves inventory accounting, multi-state considerations, and international questions if you sell abroad, and none of that is in a document library. I’d rather pay a specialist for 3 hours than guess for 30.
The three documents worth downloading every month
Not everything in the library needs regular attention. Three things do, and pulling them monthly takes about 15 minutes.
The combined sales tax report. Even where Amazon remits on your behalf, this is your evidence of what was collected in which jurisdiction. When a state sends a query two years later, this is the answer.
The fee invoice for the month. Amazon’s fee schedules change, and a fee invoice read monthly shows you a change the month it happens rather than the quarter after. I have seen sellers absorb a fee increase for half a year without noticing.
The settlement summary alongside it. Not strictly a tax document, but reconciling fees against settlements is where discrepancies surface, and discrepancies are occasionally recoverable.
Everything else can wait for year end. These three compound if you skip them, and the compounding is silent until the moment you need something you no longer have.
Using it properly
- Download monthly rather than annually. Reconstructing a year in April is unpleasant and error-prone.
- Reconcile fee invoices against settlement reports. Discrepancies happen, and finding them is how sellers recover money.
- Connect Amazon data to accounting software such as QuickBooks or Xero, through a purpose-built integration rather than manual entry.
- Give your accountant access early, ideally before year end rather than after it, when there is still time to act on what they find.
- Keep records for the period your jurisdiction requires, which is generally several years, and store them somewhere that is not only Seller Central.
In our experience the sellers who find tax season painless are the ones doing a small amount of this monthly. The ones who find it awful are reconstructing twelve months from scratch under time pressure.
Our guides to interpreting business reports and DBA or LLC for Amazon sellers cover two adjacent questions sellers usually ask at the same time, and our account management service covers the operational side while your accountant covers the rest.
FAQ
What is the Amazon Tax Document Library?
The section of Seller Central holding tax-related documents: sales tax reports showing what was collected and by whom, Form 1099-K where issued, and invoices and credit notes for Amazon’s fees. Find it under Reports, then Tax Document Library.
What is the 1099-K threshold for Amazon sellers?
The federal threshold has changed several times in recent years, with legislation lowering it, transitional thresholds applied for interim years, and a later restoration of the higher figure. Check the rule for the specific tax year with the IRS or your accountant, and note that several states set their own lower thresholds.
Do I owe tax if I did not receive a 1099-K?
Yes. Your obligation to report income does not depend on whether an information return was issued. The 1099-K reports transactions to the IRS, it does not define what is taxable, and income remains reportable regardless.
Does Amazon collect sales tax for me?
On Amazon sales, yes, in US states with sales tax, under marketplace facilitator laws. Sales through your own website or other channels where no facilitator collects remain your responsibility, and some states still expect registered sellers to file returns.
Does storing FBA inventory in a state create tax obligations?
It can, particularly for income or franchise tax purposes, and states take differing positions. Sales tax is generally handled by Amazon as marketplace facilitator, but that does not resolve other tax types. This is a question for an accountant rather than an article.
Does the Amazon Tax Document Library replace bookkeeping?
No. It stores documents rather than tracking cost of goods, inventory value, or profit, and it covers only your Amazon activity. Sellers on multiple channels need accounting that consolidates all of them.
