Get in Touch

Most messages I get fall into one of three buckets: someone spotted a tax rate that's changed, someone wants a feature added, or someone has a general question about how one of the calculators works. All three are welcome. I typically respond within 1 to 3 business days — rate corrections get priority because they affect every calculation for that state.

One thing that genuinely helps: if you're reporting that a state or city rate has changed, include a link to the official source where you verified it. A link to the state's department of revenue page, or a city council ordinance, saves me a bunch of verification time and means I can push the update faster.

For everything else — feature ideas, bug reports, questions about how the reverse sales tax calculator handles a specific scenario — just fill out the form below.
