Publication update — 29 July 2026

• The quote-comparison guidance was expanded to explain selling price, dealer fees, government charges, rebates, trade allowance and payoff as separate comparison fields.
• Cross-links between the comparison tool, methodology and official source registry were refreshed so rule evidence is easier to reach.
• The public sitemap and update feed were refreshed, and the canonical publication address remains the secure non-www domain.
• No Florida, Texas or Washington calculation rate changed.

• Washington 0.5% additional motor-vehicle tax and 2026 luxury-tax threshold and rate.
• National custom-rate estimate, reverse budget solver, trade-in tax estimate, dealer quote checker and three-quote comparison.

What triggers a calculator version change

A new version is published when a source-backed rate, threshold, government fee, tax base or transaction rule changes. Copy improvements, accessibility work and internal-link maintenance are recorded separately when they do not alter the calculation.

How changes are reviewed and deployed

An official-source change triggers source review, rule update, regression-test update, public changelog entry and a new deployment. A page review date alone does not silently alter an older formula. The methodology explains calculation order and rounding, while the source registry lists the public agencies used for each state path.
