Amazon FBA + Delaware LLC: Multi-State Tax

Sales tax: marketplace facilitator shift

Most US states have marketplace facilitator laws making Amazon responsible for sales tax collection and remittance on FBA seller sales. From the seller's perspective, sales-tax compliance is largely automatic.

Some states still require seller registration as 'remote seller' even though Amazon collects.

Income tax: more complex

FBA inventory creates physical presence in fulfillment states. Some states interpret this as income-tax nexus; others do not. State-by-state analysis varies.

California, New York, Texas, and others have specific rulings on FBA income-tax nexus. Engage CPA familiar with multi-state FBA seller taxation.

Practical pattern

Most small-medium FBA sellers (under $1M annual revenue): file in primary state(s) and monitor for state-tax notices. Most large FBA sellers (>$5M annual revenue): proactive multi-state compliance.

California is the most aggressive on FBA income-tax nexus. If you have substantial California FBA presence, expect potential state-tax filing requirements.

Why a Delaware LLC fits an FBA seller who lives abroad

If you live outside the United States and you sell physical goods through Amazon, the entity question comes before the tax question.

A Delaware LLC gives a non-resident founder a recognized US legal wrapper that Amazon, banks, and suppliers all understand, without forcing you to set foot in the country.

Amazon does not require US citizenship or residency to open a Professional seller account, but it does want a verifiable business identity, a US bank account that can receive disbursements, and a tax interview on file.

A Delaware LLC paired with an EIN satisfies all three of those checkpoints in a way a personal foreign account rarely does.

Formation itself is inexpensive relative to the inventory you will carry.

The state filing runs $110, and a full done-for-you setup through Delewarellc is $297 one time, which covers the formation work and the supporting documents you need to pass Amazon and bank verification.

For a seller who is about to ship thousands of dollars of stock into US fulfillment centers, that is a small administrative layer compared with the exposure of selling as an unregistered foreign individual.

The reason this matters for the rest of this article is sequencing.

Nexus, registration, and income-tax questions only become real once you have an entity that owns the inventory and an account that receives the money.

Get the Delaware LLC and EIN in place first, then layer the multi-state analysis on top.

Trying to reason about California or Texas exposure before you even have a US entity is putting the roof on before the walls.

The EIN timeline that controls your Amazon launch date

Most FBA delays for non-residents trace back to the EIN, not the formation.

The LLC certificate can be issued quickly, but Amazon's tax interview and your US bank both want the federal tax ID before they will finish onboarding.

As a foreign founder without a Social Security Number, you cannot use the instant online EIN tool.

You file Form SS-4 with the IRS, and the EIN typically comes back in roughly 8 to 10 business days when the form is prepared correctly.

The free part is real, the EIN costs nothing from the IRS, but the calendar cost is the wait.

Plan your inventory purchasing and shipping around that window.

A common mistake is buying stock and booking freight before the EIN exists, then watching pallets arrive at a fulfillment center while the seller account is still stuck in verification.

Order the EIN early, treat the 8 to 10 business day estimate as a floor rather than a guarantee, and only commit to inbound shipments once the tax interview clears.

When the SS-4 is filed, accuracy on the responsible-party line and the entity-type boxes is what keeps it from bouncing back.

A single-member LLC owned by one non-resident is treated by default as a disregarded entity for US tax, and the SS-4 should reflect that consistently with how you intend to file.

Getting this right at EIN stage avoids reclassification headaches later when Form 5472 and the related 1120 are due.

Choosing a bank that accepts FBA disbursements

Amazon pays sellers by depositing into a US bank account in the seller's business name, and a mismatch between the account name and the Amazon legal entity is a frequent cause of held funds.

For non-resident Delaware LLC owners the practical roster of accounts that open remotely includes Mercury, Wise, Relay, Lili, and Payoneer.

Each handles FBA payouts, but they differ in how they treat multi-currency settlement, which matters when you also sell on Amazon marketplaces outside the US.

Mercury and Relay lean toward founders who want a clean US-dollar operating account with reasonable bookkeeping integrations, which suits a seller running a single US storefront.

Wise and Payoneer shine when you are collecting in euros, pounds, or other currencies from Amazon's European or other regional stores and want to convert at transparent rates rather than absorbing a marketplace conversion spread.

Lili fits a lean solo operator who wants simple expense tracking baked in.

Whatever you pick, open the account under the exact LLC name that appears on your Delaware certificate and your Amazon account, and feed that account into Seller Central before your first disbursement cycle.

Keep the FBA payout account separate from any personal spending, because clean separation between the LLC and the owner is what supports the disregarded-entity story you will tell the IRS, and it makes the eventual bookkeeping for income-tax filings far less painful.

How FBA inventory placement actually creates nexus

The core mechanism behind this entire topic is that you do not choose where your inventory sits.

Once you enroll in FBA and ship into Amazon's network, Amazon's algorithms distribute and rebalance your stock across fulfillment centers in multiple states based on demand forecasting, capacity, and shipping speed targets.

A seller who sent one shipment to a single intake center can find units spread across half a dozen states within weeks.

Physical inventory in a state is the classic trigger for physical-presence nexus, and you did not consciously create it.

This is what separates an FBA seller from a pure dropshipper or a digital-product seller.

A SaaS founder or a print-on-demand seller without owned stock can often argue they have no physical footprint anywhere.

An FBA seller cannot, because tangible goods owned by the LLC are physically present in warehouses.

The question is not whether you have physical presence in fulfillment states, you generally do, but what each state chooses to do with that fact for its own taxes.

Because placement shifts over time, your nexus map is a moving target rather than a fixed list.

You can pull inventory event and inventory ledger reports from Seller Central to see which states have held your units.

Reviewing that report periodically, rather than once at launch, gives you the factual basis to decide where registration or filing might actually be warranted instead of guessing.

Reading your Amazon inventory reports to map your states

You do not have to speculate about where you have presence, because Amazon records it.

Inside Seller Central, the inventory ledger and the fulfillment-center-level inventory reports show the warehouse codes that have held your stock, and each code maps to a physical state.

Exporting that history turns an abstract nexus worry into a concrete list of states you can actually evaluate one at a time.

Build a simple running record.

For each state that has ever held your inventory, note when units first appeared, roughly how long they stayed, and whether that state is one of the more assertive jurisdictions on inventory-based nexus.

A state that briefly held a handful of units during a single peak season is a very different exposure than a state that has continuously warehoused a large share of your stock for a year.

Treating both identically leads either to needless registrations or to missed obligations.

Keep these exports as part of your annual records alongside your bank statements and Amazon settlement reports.

If a state ever sends a notice, contemporaneous inventory data is the cleanest evidence of when and how much presence you had.

For a non-resident founder who cannot easily walk into a state tax office, having the documentation organized in advance is worth far more than trying to reconstruct it later from memory.

Marketplace facilitator collection versus your own registration duty

It is worth being precise about what marketplace facilitator laws do and do not relieve.

In nearly every state, these laws make Amazon legally responsible for calculating, collecting, and remitting the sales tax on the transactions it facilitates.

From a cash and operational standpoint, that means you are not separately collecting sales tax from FBA buyers and you are not cutting checks to those states for the tax on Amazon sales.

That part is genuinely handled.

What the laws do not uniformly do is erase every registration obligation.

Some states still expect a seller with in-state inventory to register as a remote or marketplace seller even when Amazon remits the tax, often so the state has the seller on record and can reconcile facilitator filings.

Registration in those cases can be an informational step rather than a tax-payment step, but skipping it can still generate notices.

The distinction that trips up new sellers is conflating collection with all of sales-tax compliance.

Amazon collecting the tax does not automatically mean you have zero paperwork in a state, and it says nothing at all about income tax, which is a separate regime with its own nexus rules.

Treat the facilitator relief as solving the buyer-facing collection problem only, and analyze registration and income tax as their own questions.

Sales channels beyond Amazon change the picture

Many founders start on Amazon and then add a Shopify storefront or another off-Amazon channel, and that addition can reopen sales-tax questions that FBA had quietly handled.

On your own Shopify store you are usually the seller of record, which means marketplace facilitator relief does not apply to those sales.

If you cross a state's economic-nexus threshold through direct sales, you may have to register and collect on the Shopify channel even while Amazon continues to handle the FBA channel in the same state.

This creates a split-channel reality where one state can have Amazon remitting tax on your FBA orders while you separately owe collection on your direct orders into that same state.

Sellers who assume their Amazon experience carries over to Shopify are often surprised.

The economic-nexus thresholds, commonly framed around $100,000 in sales or 200 transactions into a state, are evaluated per the rules of each state and can include or exclude marketplace sales differently.

For a non-resident owner, the practical takeaway is to keep channel-level revenue separate in your records from day one.

Knowing exactly how much you sold directly into each state, apart from Amazon-facilitated volume, is what lets you or your accountant decide whether a direct-sales registration is required.

Mixing the two together makes it almost impossible to assess thresholds correctly.

The federal filings that matter more than most state taxes

For many non-resident FBA sellers, the largest compliance risk is not a state income-tax bill at all, it is a missed federal information return.

A single-member Delaware LLC owned by a foreign person and treated as a disregarded entity is required to file Form 5472 together with a pro forma Form 1120 each year, reporting reportable transactions between the LLC and its foreign owner.

Capital you put in, money you take out, and dealings between you and the entity are exactly the kind of items this return captures.

The reason to take it seriously is the penalty. Failure to file Form 5472, or filing it substantially incomplete or late, carries a penalty of $25,000.

That figure dwarfs the modest state income-tax exposure most small FBA sellers face, which is why a seller obsessing over California nexus while ignoring the 5472 has the priorities backward.

The federal information return is non-negotiable and applies regardless of whether the LLC was profitable.

Mark the deadline and gather the supporting numbers throughout the year rather than scrambling at filing time.

The transactions you need to report are knowable in advance because they flow through your LLC bank account and your contributions.

Keeping the FBA payout account, your capital injections, and any owner draws clearly labeled in your bookkeeping is what makes assembling an accurate 5472 straightforward rather than a year-end fire drill.

BOI reporting after the 2025 rule change

Beneficial ownership reporting under the Corporate Transparency Act was a live worry for new LLC owners through 2024 and early 2025, and a lot of older guidance online still treats it as a universal obligation.

The landscape changed. Under the FinCEN interim final rule issued March 26, 2025, US-formed entities, including a domestic Delaware LLC, are exempt from the BOI reporting requirement.

For a Delaware LLC formed by a non-resident, this means the BOI filing that earlier articles described is not something you owe.

This is a genuine simplification for the FBA founder, because it removes a recurring filing and the associated penalty anxiety from the compliance stack.

It does not, however, touch any of the other obligations discussed here.

The BOI exemption says nothing about Form 5472, nothing about the Delaware franchise tax, and nothing about state sales or income tax tied to your inventory. Each of those stands on its own.

Be cautious with dated checklists and service providers that still advertise BOI filing as a required add-on for US LLCs.

Because the rule shifted in 2025, content written before that date may quietly oversell a service you no longer need.

When you see BOI described as mandatory for a domestic LLC, check the date of the source against the March 26, 2025 interim final rule before acting on it.

Delaware franchise tax: the one bill you will never miss

Whatever your multi-state sales picture looks like, Delaware itself wants its annual franchise tax, and for a standard LLC that is a flat $300 due by June 1 each year.

This is not based on revenue, profit, or where your inventory sits. It is a fixed cost of keeping the Delaware LLC in good standing, and it applies whether you sold a thousand units or zero.

For an FBA seller juggling several states, it is reassuring that the home-state obligation is at least simple and predictable.

The franchise tax is easy to underestimate precisely because it is small and routine.

Missing the June 1 deadline adds penalty and interest and, if left unpaid, can push the LLC out of good standing, which then ripples into your ability to maintain bank accounts and your Amazon account in the LLC's name.

The cost of forgetting is out of proportion to the size of the bill, so it deserves a calendar reminder set well before the date.

Because the franchise tax and the federal Form 5472 both land in the first half of the year, it is efficient to treat them as a single annual compliance moment.

Pay the $300 Delaware franchise tax by June 1, file the 5472 with its 1120 on the federal schedule, and you have cleared the two obligations that apply to essentially every non-resident Delaware LLC regardless of FBA specifics.

Bookkeeping habits that make multi-state questions answerable

Almost every hard question in this article becomes easy with good records and impossible without them.

The recurring theme is that you need three things tracked cleanly: where your inventory has been, how much you sold into each state by channel, and every transaction between you and the LLC.

None of these require an expensive system, but all of them require consistency from the first month rather than a reconstruction effort at year-end.

Route all FBA disbursements through one LLC bank account, whether that is Mercury, Relay, Wise, Lili, or Payoneer, and resist the temptation to let funds touch a personal account in between.

Pull Amazon settlement and inventory reports on a regular cadence and store them. Tag your own capital contributions and any draws distinctly.

With those habits, a request from a state, an accountant, or the IRS turns into an export rather than an investigation.

For a non-resident founder, this discipline is also a defensive posture.

You are operating a US entity from abroad, often without an in-country accountant on retainer, so the records you keep are your primary line of evidence.

When you eventually engage a CPA to evaluate income-tax nexus in an assertive state, the quality of your inventory and revenue data directly determines how cheaply and confidently they can answer the question.

A right-sized action plan by seller stage

Match your compliance effort to your scale instead of trying to do everything on day one.

A new or small FBA seller, roughly under $1M in annual revenue, should prioritize the universal obligations first: keep the Delaware LLC in good standing with the $300 franchise tax by June 1, file Form 5472 with its 1120 to avoid the $25,000 penalty, rely on Amazon's marketplace facilitator collection for FBA sales tax, and simply monitor for any state notices while keeping inventory and revenue records clean.

A growing seller adding direct channels or pushing serious volume into assertive states should layer on more.

That means evaluating direct-sales economic nexus on Shopify or other non-Amazon channels, checking whether any inventory state requires remote-seller registration even under facilitator collection, and engaging a CPA who genuinely understands multi-state FBA taxation rather than a generalist.

The most assertive states on inventory-based income-tax nexus deserve specific attention once your presence there is substantial and continuous.

Across both stages, the sequence is the same.

Stand up the Delaware LLC and EIN, open an FBA-friendly bank account in the LLC's name, get the federal and Delaware obligations on a fixed annual calendar, and treat state-by-state analysis as an ongoing review driven by your actual inventory and channel data.

Done in that order, multi-state tax stops being a source of dread and becomes a manageable annual routine for a founder running the whole operation from outside the United States.
