United States: state thresholds need state-level sales
There is no single US threshold. Economic-nexus tests run state by state, so a national total cannot answer them. The thresholds currently modeled:
| State | Sales threshold | Transactions test |
|---|---|---|
| CA | US$500,000 | None modeled |
| FL | US$100,000 | None modeled |
| GA | US$100,000 | 200 · OR: either test triggers |
| IL | US$100,000 | None modeled |
| NC | US$100,000 | None modeled |
| NY | US$500,000 | 100 · AND: both tests must be met |
| OH | US$100,000 | 200 · OR: either test triggers |
| PA | US$100,000 | None modeled |
| TX | US$500,000 | None modeled |
| WA | US$100,000 | None modeled |
This calculator compares the figures you enter with modeled registration thresholds. It does not decide whether you must register, collect or file, and it does not cover stock-related triggers. The free self-check reviews channels, stock and imports together.
Common questions
Why does the calculator show a zero threshold for overseas sellers?
The UK £90,000 threshold applies to UK-established businesses, and the EU €10,000 threshold to EU-established ones. A non-established seller making taxable supplies, such as selling goods held in the country, generally registers from the first sale.
Which US threshold should I use?
None on a national total. US economic nexus runs state by state, with different amounts, periods and transaction tests. Export state-level sales before drawing any conclusion.
Does staying below a threshold mean nothing to do?
Not by itself. Stock in a market, marketplace rules and import treatment can create obligations below any turnover threshold. Those interactions are what the free self-check reviews.
