Amazon collects your sales tax. That does not mean you have no tax obligations.

Key takeaways

• All 45 US states with a general sales tax, plus DC, have marketplace facilitator laws. Amazon collects and remits sales tax on your marketplace orders in every one of them.
• Marketplace laws touch sales tax and nothing else. Income tax, franchise tax and gross-receipts tax arising from FBA inventory are entirely the seller's responsibility.
• FBA inventory will create physical nexus in a state regardless of revenue — even one pallet — which the economic threshold does not protect against.
• Your Amazon sales will count toward economic nexus thresholds in many states. You can cross a threshold on Amazon volume, owe a registration for your Shopify sales, and never notice.
• This guide is not tax advice, and this subject is one where a specialist earns their fee. It exists so you know which questions to ask.

Most sellers learn one fact about this subject — Amazon handles sales tax — and stop. It is a true fact, and it covers roughly a third of what a multi-state FBA seller is exposed to.

Nothing here is tax advice. The purpose is to make the shape of the problem visible so you can take it to someone qualified before a state revenue department takes it to you.

01What marketplace facilitator laws actually do

Reporting is consistent: all 45 states with a general sales tax, plus the District of Columbia, have enacted marketplace facilitator laws as of 2026. Under them, Amazon is required to calculate, collect and remit sales tax on orders placed through its marketplace.

Five states have no general sales tax at all: Alaska, Delaware, Montana, New Hampshire and Oregon.

For marketplace orders, that work genuinely is off your plate. The problems are all in what the laws do not cover.

02The four exposures

1. FBA inventory creates physical nexus

This is the one that catches people, and the mechanism is uncomfortable: you did not choose where your inventory goes. Amazon distributes it across its network, and each state where it is stored is creating physical nexus for sales, income and franchise tax purposes.

Reporting is direct that FBA inventory creates physical nexus regardless of revenue — even one pallet — and that the economic threshold offers no protection against it. Amazon reports inventory locations in seller reports, and the number of states involved at 20 or more, varying over time.

Our inbound placement guide covers the fee side of that distribution. This is the other consequence of it.

2. Income tax, which nobody mentions

Reporting from one tax firm states plainly that FBA sellers routinely overlook income tax exposure in FBA warehouse states.

The logic follows from the first point. Physical nexus from stored inventory will create income tax obligations, not only sales tax ones, in the roughly 40 states with a corporate income or franchise tax. state minimums exist regardless of profit — an $800 California minimum is the figure most commonly cited.

Amazon collecting sales tax does nothing about this.

3. Your non-marketplace sales

If you also sell on Shopify, your own site, or wholesale, those sales are not covered by marketplace facilitator laws. You collect and remit sales tax on them yourself in every state where you have nexus.

This is where multi-channel sellers get burned, and there is a specific trap in it. several states count your marketplace sales toward your economic nexus total. So you can cross a state’s threshold on the strength of Amazon volume alone, owe a registration in that state for your direct sales, and never realize it — because the marketplace was quietly handling its own collection the whole time.

4. Registration and filing, even at zero

many states still want you registered and filing returns — zero-dollar returns, or returns claiming a marketplace deduction — even when Amazon collects 100% of the tax.

There are also gaps at the local level. some states, with Arizona, California and Colorado named, require separate seller filings for local taxes even where Amazon handles state-level collection, and that marketplaces often do not collect city-level taxes such as certain Colorado home-rule rates or some Alabama local variations.

03The realistic exposure picture

Obligation	Covered by Amazon?
Sales tax on Amazon marketplace orders	Yes, in all 45 states plus DC
Sales tax on your Shopify or direct sales	No
Certain city and home-rule local taxes	Often not — varies by state; check the state DOR
Registration in nexus states	No
Zero-dollar or marketplace-deduction filings	No
Income tax in FBA warehouse states	No
Franchise and gross-receipts tax	No
State minimum taxes	No

04Structure, briefly

One point appears consistently enough to mention, with a caution attached.

an LLC to S-Corp election at around $50,000 or more in net profit as saving many FBA sellers $5,000 to $15,000 a year in self-employment tax. That is one firm’s figure, published by a firm that sells tax planning, and whether it applies depends on your profit, your salary, your state and your circumstances.

It is included here because the threshold is a useful prompt for a conversation, not because it is advice. If your net profit is approaching that level and nobody has raised the question with you, raise it yourself.

05Records, which decide how bad an audit is

the IRS requires records to be maintained for at least three years, with seven recommended.

For an FBA business the records that matter go beyond receipts:

• Settlement reports — the actual money, per period
• Inventory location reports — the evidence of where nexus arose and when
• Supplier invoices — which, as the reimbursement and suspension guides cover, you now need for two other reasons
• Fee reports at SKU level — because fees are deductible and they are not one line

06What to do

Pull your inventory location report first. It tells you which states your stock has been stored in. That list is your nexus footprint, and most sellers have never looked at it.

Separate the four questions. Sales tax on marketplace orders, sales tax on direct sales, registration and filing obligations, and income or franchise tax. They have different answers in the same state.

Do not assume marketplace collection removed everything. Reporting is unanimous on this point and it is the single most common misunderstanding in the subject.

Track your Amazon sales against state thresholds anyway, even though Amazon collects. In several states those sales count toward the total that creates your own registration obligation.

Take it to a specialist if you have multi-state inventory or a second channel. voluntary disclosure agreements as a route that limits the look-back period, against unlimited exposure on unfiled returns. That is a conversation to have before a state contacts you, not after.

Keep the records for seven years, and keep them in a form somebody else could follow.

List every state where your inventory sat in an Amazon warehouse last year — the Inventory Event Detail report tells you. For each one, answer one question: do I sell anything there outside Amazon? Every yes is a registration you may owe.

Frequently asked

Does Amazon handle my sales tax?

For orders placed through the Amazon marketplace, yes, in all 45 sales-tax states plus DC. It does not cover your direct sales, certain local taxes, your registration obligations, or any income and franchise tax.

Does FBA create nexus?

FBA inventory creates physical nexus in every state where it is stored, regardless of revenue — even one pallet — and that the economic threshold does not protect against it.

Do I still have to register in states where Amazon collects?

many states still require registration and filing, including zero-dollar or marketplace-deduction returns, even where the marketplace collects all the tax.

Do my Amazon sales count toward economic nexus?

several states count marketplace sales toward the economic nexus total. You can cross a threshold on Amazon volume and owe a registration for your direct sales without noticing.

What about income tax?

income, franchise and gross-receipts tax arising from FBA inventory as entirely the seller's responsibility, in the roughly 40 states that levy them, and states that FBA sellers routinely overlook this.

Is this tax advice?

No. This site is not a tax adviser and this guide is a map of the questions, not answers to them. Multi-state inventory plus a second sales channel is a situation where a specialist earns their fee.
