Last updated August 31, 2026. This notice describes the current calculator website.

Your calculator entries

Calculations run in your browser. This application does not send salary or W-4 entries to an application server, put them in URLs, or store them in browser storage. Resetting or leaving the page clears the calculator state. Do not enter your name, Social Security number or other identifying information.

Hosting and access

The hosting platform may process technical access data and authentication cookies to operate and secure this site. We use Cloudflare Web Analytics to measure page visits and loading performance. Calculator amounts and W-4 answers are not sent to analytics. We do not install advertising or session-recording tools. Hosting and analytics operations are separate from the calculator. See the Cloudflare privacy policy at https://www.cloudflare.com/privacypolicy/. No salary inputs are included in application access URLs.
