Quick Answer
Every rate page on this website carries a rate status that says where its number came from and how far it has been checked. Nothing here is described as verified unless an official source was actually opened for that record. Where a rate is not available, no number is shown at all.
Of the 4,509 local rate pages on this site, 664 have been confirmed against the official state source, and 3,845 have not. Each page says which group it belongs to.
The five rate statuses
Each city, county, parish, borough, municipality, and equivalent jurisdiction page is assigned exactly one of these. The counts below are generated from the current dataset.
| Rate status | What it means | City pages | County-equivalent pages |
|---|---|---|---|
| Local rate from the official state rate table | Carried from the official state rate table cited on the page. | 664 | 0 |
| Local rate from an official table with an earlier effective date | From an official state table whose effective date predates the current year; reconfirm before filing. | 93 | 0 |
| Statewide rate; no local add-on recorded | The jurisdiction applies one rate with no county, city, or district add-on recorded. | 3,207 | 489 |
| No broad statewide sales tax recorded | No broad statewide sales tax recorded. Other transaction taxes may still apply. | 545 | 49 |
| Combined rate not available in this dataset | No combined rate is stored, so none is shown. | 0 | 2,684 |
Which official sources the local rates come from
| Jurisdiction | Source agency and document | Rate effective | Source opened and checked | Pages |
|---|---|---|---|---|
| California | California Department of Tax and Fee Administration (CDTFA) — California City and County Sales and Use Tax Rates | July 1, 2026 | August 6, 2026 | 483 |
| Florida | Florida Department of Revenue — Form DR-15DSS, Discretionary Sales Surtax Information (current edition) | Current edition | August 6, 2026 | 255 |
| New York | New York State Department of Taxation and Finance — Publication 718, New York State Sales and Use Tax Rates by Jurisdiction | March 1, 2025 | Not re-checked | 19 |
What “checked” does and does not mean here
These fields are kept separate on purpose, because collapsing them is how a build date ends up being shown to readers as a verification date:
- Rate effective date — the date the official source says the rate takes effect.
- Source last updated — the revision date printed on the official document itself.
- Official source opened and checked — whether the official source was actually opened to confirm this record, and on what date. Where this says “No”, the figure was carried from the underlying dataset and has not been re-confirmed against the agency.
A code deployment date is not a data-verification date, and this site does not display one as if it were. For any figure you will rely on to collect, invoice, or file, open the official source linked on the page and check the exact address.
Known limitations in the current data
- County-equivalent coverage. 2,684 of 3,222 county-equivalent pages have no combined rate in the dataset. Those pages say so rather than showing a placeholder, a zero, or the bare statewide figure presented as a county rate.
- City coverage. City-level pages exist for 16 of 52 jurisdictions. The rest have state guides only.
- Averages. Where a page shows an average combined rate, that is an average across the jurisdictions in this dataset. It is not an exact rate for any single transaction and not a figure published by the state.
- Cohort wording. Where a page says “of the N cities in this dataset,” that cohort is exactly the jurisdictions this site holds data for, not every incorporated place in the state.
How the comparison figures are calculated
Rankings, averages, medians, percentiles, county spreads, and the tax-on-a-purchase tables are computed arithmetically from the stored rates. They are not sourced separately and are not official statistics.
