Effective date: August 6, 2026. By using calceva.com you agree to these terms. If you do not agree, do not use the site.
Estimates, not advice
In particular: employer withholding methods differ from annual liability; local rules change mid-year; and your final bill is settled by your tax return, not by any calculator — including ours.
What you may do
Use the calculators freely, for personal or professional planning. Link to any page. Quote reasonable excerpts of our explanations with attribution and a link.
What you may not do
Scrape, republish, or resell the site's content or data wholesale; misrepresent Calceva results as an official government computation; use the site in any way that disrupts it for others; or frame the site to hide its origin.
No warranty, limited liability
The site is provided "as is", without warranties of any kind, express or implied, including accuracy, completeness, or fitness for a particular purpose. We verify our data against official sources and test every formula before release — the process is documented on the methodology page — but tax rules change and mistakes are possible. To the maximum extent permitted by law, Calceva is not liable for any loss or damage arising from reliance on the site's results. Your sole remedy for dissatisfaction is to stop using the site — and ideally to tell us what went wrong so we can fix it.
Intellectual property
The Calceva name, design, texts, and calculation specifications are ours. Official tax figures themselves are public information; our compilation, presentation, and verification of them are not.
Changes to these terms
We may update these terms; the current version always lives at this address with its effective date. Continued use after a change means acceptance.
