What changes when sales tax nexus rules differ in California, Texas, New York and Florida?

What to take away

Nexus is not one rule: how four states draw the line

Nexus is the connection between a seller and a state that lets that state require tax collection. Physical presence, such as an office, inventory or a traveling salesperson, creates it. So does economic activity above a state-set threshold. Each state writes its own version, which is why one national policy does not exist.

How states structure sales tax differs in ways that reach the ledger, not just the tax return. Some states let cities and counties add their own rates, some run a single statewide rate, and some tax services that others exempt.

A seller registered in four states is running four small tax systems on one set of books. The differences are not cosmetic. They decide which account a dollar of tax lands in and which return claims it.

Thresholds are measured on gross receipts, total sales of tangible goods or taxable remote sales, depending on the state. Some also count transactions, and New York requires both tests to be passed. A seller can be collecting in one state and not yet registered in another on the same day.

Registration starts the clock on collection, filing and remittance. From the first taxable sale after registration, the seller owes tax to that state whether or not the customer was charged it. That is an accounting problem before it is a tax problem.

Because rules vary this much, a single multi-state sales tax account hides what is owed where. The chart of accounts has to carry the state, the tax type and the filing period. That is the thread running through the rest of this article.

California economic nexus and district taxes

The California economic nexus threshold is $500,000 in sales of tangible personal property delivered into the state in the preceding or current calendar year. Retailers above it must register with the California Department of Tax and Fee Administration and collect.

The threshold counts the total combined sales of tangible personal property for delivery in California by the retailer and all persons related to it. Wholesale and exempt sales of goods count toward it; sales of services do not, because they are not tangible personal property. A California seller moving $600,000 of wholesale goods and $300,000 of retail goods is over the threshold, because the wholesale sales alone exceed $500,000.

California runs a statewide base rate and then adds district taxes approved by local voters. The California tax and fee rates change as districts are approved, so the base alone rarely reflects what a buyer pays.

Rates vary by address, so the same item can carry a different total rate two ZIP codes apart. The CDTFA publishes current California city and county rates, which is the reference to check before invoicing.

District taxes are not uniform in scope. Some districts tax only specified categories, and use tax on out-of-state purchases can follow a different set of district boundaries than sales tax. A seller with one blended rate in the system will misstate what is owed.

California also taxes use tax, the mirror of sales tax on items bought without tax and used in the state. Remote sellers registered here collect both under the California sales and use tax program, and the return separates state, local and district portions.

That split has to exist in the books before the return is filed.

For sellers below the threshold, no collection duty exists, but the sales still belong in revenue recording at the right amount and in the right period. Tracking cumulative California sales of tangible goods by month, wholesale included, is what tells you when the threshold is close.

Texas nexus thresholds and remote seller rules

The Texas nexus threshold is $500,000 in total Texas revenue in the preceding twelve calendar months. The measure is a rolling twelve months, so a seller can cross it mid-year. A remote seller that exceeds it must obtain a permit and begin collecting no later than the first day of the fourth month after the month it crossed.

Total Texas revenue is broader than taxable sales. It includes sales of taxable goods, exempt goods, services and sales for resale. A remote seller with large wholesale volume can cross the Texas threshold while collecting tax on almost nothing.

That distinction matters for monitoring. A seller watching only taxable sales will undercount and miss the trigger. The right control is a running twelve-month total of all Texas revenue, reviewed at each month end.

Once registered, a remote seller collects Texas state tax plus any local sales and use taxes that apply at the ship-to address. Texas runs a single state rate with city, county, transit and special purpose districts layered on, capped at a combined local maximum.

Texas is a destination state, so the rate is set by where the buyer receives the goods, not where the seller sits. Shipping addresses, not billing addresses, drive the tax on each invoice.

Filing frequency depends on the tax due. Small remitters file quarterly or annually, larger ones monthly, and prepayment rules apply to the biggest. Each frequency creates a different close routine and a different liability balance at month end.

New York's threshold and the marketplace provider rules

The New York nexus threshold has two tests, and a remote seller with no physical presence must pass both before a vendor collection duty arises. The first is more than $500,000 in receipts from sales of tangible personal property delivered in the state in the last four sales tax quarters. The second is more than 100 such sales in the same period.

Because both must be met, a seller with many small orders is not caught by the count alone. A seller with 120 orders totaling $8,000 passes the transaction test but not the dollar test, so it has no collection duty. A high-value seller with few orders is outside it too. Both tests count only tangible personal property delivered into New York, so services and digital goods sit outside them.

New York also runs a marketplace provider rule. A marketplace provider that facilitates sales for third-party sellers must collect and remit on those sales, and it is treated as the vendor for that purpose. The marketplace, not the underlying seller, is on the hook for the tax on facilitated sales.

Marketplace sellers still have duties. They must register, file returns and report marketplace sales, even when the marketplace collected the tax. The return shows the facilitated sales and a corresponding credit, so the seller's books need both the gross sale and the tax collected by someone else.

New York City adds its own rate on top of the state rate, and the combined rate in the city is higher than most of upstate. Registration and vendor collection obligations run through the state Tax Department, which publishes the New York sales tax filing rules sellers follow.

A New York registration usually arrives with a quarterly filing requirement and a certificate of authority. The certificate is what lets a seller buy inventory for resale without paying tax, so it belongs with the vendor records, not the tax file.

Florida nexus and the registration trigger

Florida has two registration triggers, and the Florida Department of Revenue administers both. The first is economic: under the Florida statute on remote sales, a seller outside the state makes a substantial number of remote sales when its taxable remote sales in the previous calendar year exceeded $100,000, and every such seller is a dealer that must register and collect. The second trigger is physical presence: an office, employees, inventory in a warehouse, or agents working in the state.

That does not mean Florida is simple. Sellers with Florida inventory, including inventory held in a third-party fulfillment warehouse, have physical presence and must register. Fulfillment arrangements are the most common way an out-of-state seller ends up registered here.

Florida also has a marketplace facilitator law, so marketplaces collect on facilitated sales. A seller whose only Florida activity runs through a marketplace may have no direct collection duty, but the marketplace sales still appear in the seller's records and returns.

Sellers below the threshold and without physical presence can register voluntarily and collect. That is a business decision, not a legal requirement, and it brings filing obligations, a Florida annual resale certificate and a use tax duty on items withdrawn from inventory.

Florida's state rate is uniform, and county discretionary surtaxes apply on the first dollars of a sale rather than the full amount. That cap makes Florida county tax different from the local taxes in the other three states, and it has to be coded that way.

Registration in Florida brings a certificate number, a filing frequency based on expected tax, and a requirement to file even in periods with no sales. A zero return is still a return.

How registrations, collection and remittance reshape the chart of accounts

One sales tax payable account cannot serve four states. Each registration needs its own liability account, because each state is a separate creditor and each return is a separate filing. Combining them makes reconciliation guesswork.

A workable structure puts a parent liability under current liabilities and a child account per state and tax type. California splits into state, local and district portions on the return, so the account structure should mirror that split rather than collapse it.

Marketplace sales need their own treatment. When a marketplace collects the tax, the seller never holds the cash, so the liability should not sit in the seller's payable account. Recording it there and crediting it away at filing time creates a balance that never clears.

The table below shows how the same sale lands differently depending on who collects.

Exempt and resale sales need a control too. A seller with heavy wholesale volume, as in Texas, has to prove what was excluded from the threshold measure. Keeping resale certificates attached to the customer record is what makes that provable at audit.

Use tax belongs in the same structure. Items bought without tax and used in a registered state create a use tax liability, often in a separate account from sales tax collected. Mixing the two hides the amount owed on purchases.

None of this works if the underlying revenue is recorded inconsistently. Gross versus net treatment changes the tax base and the liability, which is why the revenue policy and the tax policy have to be set together. The chart of accounts is where that policy becomes visible.

Building a multi-state sales tax schedule into the monthly close

A multi-state schedule turns four sets of rules into one repeatable close routine. Build it once, then run it every month in the same order.

Step three is where most schedules break. If the payable account does not tie to the return, the difference is usually a rate change, a district boundary, or a marketplace sale recorded twice. Fix the coding before adjusting the balance.

A monthly checklist keeps the schedule honest:

The schedule should live next to the bank reconciliation so cash received, tax collected and tax remitted are checked in one pass. Tax that was collected but not remitted is a cash problem as much as a filing problem.

Worked example. A seller ships from one warehouse and has $700,000 in trailing revenue split $400,000 California retail, $150,000 Texas total and $150,000 New York tangible goods across 90 orders. California is under its $500,000 threshold and Texas is under its $500,000 total revenue threshold.

New York is under both of its tests: receipts are well below $500,000 and 90 orders is fewer than 100 sales. So no state requires registration yet. The books need a running threshold monitor per state, with the New York transaction count beside the dollar total. Nothing else changes yet.

Two months later the same seller adds a Florida fulfillment warehouse. Physical presence now exists, so Florida registration follows, and the schedule gains a Florida surtax account and a filing date. The threshold tests did not change; the facts did.

That is the pattern to expect. Registrations arrive one at a time, usually because of a warehouse, a marketplace or a growth year, and each one adds accounts and close steps.

Reviewing the schedule monthly is what keeps the books aligned with the rules, and it is a normal part of bookkeeping foundations for any seller shipping beyond one state.

Software helps, but the mapping is a judgment call. Rate tables change, district boundaries shift and marketplace rules get amended. The chart of accounts trends point the same way: the account structure is becoming an interface between systems rather than a fixed list, and sales tax is one of the clearest examples.
