Every figure this tracker uses is public: each state's dollar threshold, its transaction-count test where one exists, and whether that test is combined with an AND or an OR. A spreadsheet can hold the same 51 rows. Transcribing them correctly, keeping the AND/OR logic right for the states that pair the two tests, and noticing when a state changes its rule is the part that gets skipped when you need an answer today.
| Job | A spreadsheet you build | This tracker |
|---|---|---|
| Where the 51 jurisdictions' figures come from | You look each one up and type it in, then keep it current yourself. | Already built in, compiled from named, dated sources. |
| Handling the ~16 states with a transaction-count test | You have to notice which states pair it with AND vs. OR and write two different formulas. | Applies the right rule per state automatically. |
| A state that requires both figures together but you've only entered sales | A formula that isn't written to catch this will silently return crossed or not-crossed either way. | Says outright it needs a transaction count before it will guess. |
| A state with no sales tax at all | You have to remember to exclude Alaska, Delaware, Montana, New Hampshire, and Oregon or a large number there reads as crossed. | Already knows those five states have no threshold to cross. |
| Cost | Free, but your time to build and keep it correct. | Free. |
| Where your sales data goes | Wherever you save the file. | Nowhere — stays in your browser's local storage, never uploaded. |
Yes. Every figure this tracker uses — each state's dollar threshold, its transaction-count test where one exists, and whether that test is combined with an AND or an OR — is public information you can type into a spreadsheet yourself. Building it means transcribing all 51 jurisdictions correctly, including the roughly sixteen that pair a transaction count onto the dollar figure, and updating any cell a state changes (Illinois dropped its 200-transaction alternative entirely as of 2026-01-01).
Keep the AND/OR logic right without you re-deriving it per state. Connecticut and New York require both the dollar figure and a transaction count together (AND) — most other transaction-count states need only one or the other (OR). A spreadsheet formula that treats every state the same way will misjudge Connecticut or New York specifically. This tracker also states outright when it needs a transaction count it doesn't have, rather than defaulting to a silent guess, and it already knows which states levy no sales tax at all so a large number there never reads as crossed.
Yes, if you want to do more with the numbers than check a threshold — combine nexus tracking with other tax reporting, chart your trailing sales over time, or keep a running history from filing period to filing period. This tracker holds only what you've entered right now; a spreadsheet you build and save yourself can be extended to do anything you can formula your way into.
No account and no network requests — the tracker runs entirely in your browser. Whatever you enter is saved to this browser's local storage between visits and never sent to a server, the same as a spreadsheet file that never leaves your own computer.
This page names no specific product — it compares against the generic method of tracking economic-nexus thresholds in a spreadsheet, not a competing tool.
