The daily board resets every night at midnight (Paris).SalesTaxly is a US sales tax lookup service built for online sellers. You give it an address or a postal code, and it returns the combined tax rate for that exact location, broken down into its state, county, city and special district parts. There is a web lookup for one-off checks and an API for stores that need a rate at checkout, plus bulk lookups when you have a whole file of addresses to price.
SalesTaxly appears on premierdelaclasse.lol, a satirical leaderboard where the ranking is bought rather than earned. SalesTaxly simply holds the spot its bid pays for, nothing more: no jury, no test, no score to read into. This page is an editorial look at what the product actually does, so you can judge the tool on its own merits instead of on where it sits in a paid list.
The problem SalesTaxly solves
US sales tax is not a single number. It changes by state, county, city and special district, and, as SalesTaxly points out, it changes often. For an online seller shipping across the country, that means the correct rate depends on where the buyer actually is, right down to the address.
SalesTaxly's job is to turn that address into the current combined rate, so the amount you charge at checkout matches the buyer's real location rather than a rough state average. The response also splits the rate into its parts, which is useful when you need to see exactly which jurisdiction each slice of tax belongs to.
How the address lookup works
The flow is short. You sign up and receive an API key, or you use the web lookup for individual checks. You then submit an address or a postal code, and SalesTaxly returns the combined rate along with the component breakdown: state, county, city and district.
Coverage spans the US jurisdictions that levy a sales tax, and lookups accept either a full address or a postal code. For larger jobs, the bulk lookup lets you upload multiple addresses and receive the rates back as a file, which fits catalogs and order exports rather than one-at-a-time checks.
Plans and pricing
SalesTaxly publishes three monthly plans. Lookup is $9 a month and includes 1,000 API calls plus the web lookup. Store, marked as the popular option, is $19 a month with 10,000 API calls, bulk lookups and email support. Scale is $49 a month with 50,000 API calls, a priority endpoint, downloadable results and priority support.
All three plans come with a 14 day money back guarantee, so the tiers differ mainly on call volume and the extras (bulk uploads, downloadable results, priority support) rather than on the core lookup itself.
Who it is for
The tool is aimed at online store owners and e-commerce businesses that need an accurate rate at the point of sale. If you sell into many states and want the charge to follow the buyer's address instead of a broad state figure, address level lookup is the whole point.
The web interface suits occasional manual checks, while the API and bulk lookups suit stores that price many orders automatically or reprice a long list of addresses in one pass. Which plan fits comes down to how many lookups you run each month and whether you need the file based tools.
