Reporting a wrong figure

This is the most useful message you can send, and it gets answered first. To make it actionable, include:

• The state page, and which fee or rate looks wrong
• What you believe the correct figure is
• Where that comes from — a link to the agency's fee schedule, the published PDF, or the statute section
• If it is a local tax rate, the ZIP code or city it applies to

A source is what turns a report into a fix. Without one it still gets read, but it has to be researched from scratch before anything can change — and if two credible sources disagree, the safest outcome is that the disputed rate is removed rather than guessed at.

Requesting a state

States are prioritised by search demand and by how badly the existing tools serve them, but a specific reason moves things along — an unusual local tax, a fee no other calculator handles, a rule everyone gets wrong. Say which state and what makes it awkward.

Methodology questions

Every state page carries its own sources and a “how this calculator works” section, and the about page sets out the rules used to decide what gets published. If something there is unclear or looks inconsistent, that is worth an email too — ambiguity in the method is a defect.

What this address is not for

It cannot tell you what your own dealer will charge, register a vehicle for you, or resolve a dispute with a motor vehicle agency — the site publishes estimates, not quotes, and has no access to any account or record of yours. Guest post pitches, link exchanges and paid placements are declined without reply.
