Physical nexus is the older of the two sales tax nexus tests and the one people assume no longer matters. It does. A single employee, a pallet of stock in a third-party warehouse, or a few days at a trade show can create a registration obligation in a state where you have sold almost nothing.
What Physical Nexus Is
Physical nexus exists when your business has a tangible connection to a state — property, people or activity within its borders. Unlike economic nexus, there is usually no threshold to cross. The connection either exists or it does not, and one qualifying activity is generally enough.
That absence of a threshold is what catches businesses out. A company can have $2,000 of sales in a state and still be required to register because it stores inventory there.
Activities That Create Physical Nexus
- An office, store, showroom or other place of business
- A warehouse, fulfilment centre or storage unit
- Inventory or other property held in the state, including stock held by someone else on your behalf
- Employees living or working in the state, including fully remote staff
- Sales representatives, agents or independent contractors acting for you
- Delivery in your own vehicles rather than by common carrier
- Installation, assembly, repair or training performed in the state
- Trade shows, craft fairs, markets and other temporary selling activity
States differ on the detail — particularly on contractors, remote workers and how many trade show days are tolerated — so the presence of an activity on this list is a prompt to check that state’s rule, not a conclusion.
Inventory and Warehouse Nexus
Stored inventory is the most common accidental trigger. In most states, goods held for sale within the state create physical nexus regardless of who owns the building or who moved the stock there.
The problems arise because the seller often does not know where the stock is. Third-party logistics providers redistribute inventory between facilities for speed, and that redistribution can create nexus in states the seller never chose. If you use a 3PL, ask which facilities have held your goods — the answer is frequently longer than expected.
Employees and Contractors in Another State
A single employee working from home in another state generally creates physical nexus there, even if their role has nothing to do with sales. Remote hiring has made this one of the most frequently missed obligations, because the decision is made by whoever is recruiting rather than by whoever handles tax.
Contractors and agents can create it too where they act on your behalf — soliciting orders, providing service, or representing the business in the state. The label on the working relationship matters less than what the person actually does.
Fulfilment Programmes and Stored Stock
Sellers using Amazon FBA or similar programmes place inventory into a network of warehouses across many states. In most states that stock creates physical nexus for the seller, not the platform.
This interacts awkwardly with marketplace facilitator rules. The platform may collect and remit tax on your marketplace orders while your stored inventory still obliges you to register — and your own direct sales in that state remain entirely your responsibility. Marketplace facilitator laws and sales tax nexus covers the interaction.
Trade Shows and Temporary Activity
Attending a trade show, market or convention can create nexus, and the rules are specific. Some states allow a limited number of days per year before nexus attaches; some distinguish taking orders from merely exhibiting; some require a temporary permit for any on-site selling at all.
Because the thresholds are measured in days rather than dollars, a business can create an obligation over a long weekend.
Physical Nexus Compared With Economic Nexus
| Physical nexus | Economic nexus |
|---|---|
| Triggered by presence | Triggered by sales activity |
| Property, inventory, people | Revenue or transaction counts |
| Usually no threshold | Defined threshold per state |
| Applies at any sales volume | Applies only above the threshold |
| Pre-dates Wayfair | Established after Wayfair |
The two are cumulative, not alternative. A business can have physical nexus in one state, economic nexus in several others, and both in a state where it holds stock and sells heavily. Meeting either test is sufficient on its own.
What to Do When Physical Nexus Exists
- Identify the date the presence began — it usually determines when the obligation started.
- Check that state’s specific rule, since treatment of contractors, remote staff and temporary activity varies.
- Register for a sales tax account in that state.
- Begin collecting on taxable sales into the state.
- File on the assigned schedule, including periods with no sales in most states.
Physical presence often pre-dates the discovery of it, so if the activity has been running for some time, deal with the back period deliberately rather than registering and hoping the question does not come up. You can start a sales tax registration, or have deadlines, renewals and additional-state exposure tracked through our sales tax compliance monitoring service.
Frequently Asked Questions
Does physical nexus require an office or store?
No. Inventory, a remote employee, a contractor or temporary selling activity can each be enough without any premises of your own.
Can one remote employee create nexus?
In most states, yes — generally regardless of whether the role involves sales.
Does inventory stored by a marketplace create nexus for me?
In most states the seller who owns the goods has the connection, not the platform storing them.
Is physical nexus the same as economic nexus?
No. Physical nexus is about presence and usually has no threshold; economic nexus is about sales volume measured against a defined figure.
