Salary, hourly pay, filing status, deductions and withholding inputs are calculated in your browser. This application does not send those entries to a server, put them into a URL, store them in cookies or local storage, or submit them to an AI service.
Site delivery
Cloudflare serves the website and receives ordinary connection information needed to deliver it, such as the requested page, IP address and browser connection details. That is separate from the calculator inputs, which stay in your browser. This release includes no advertising, account system, payment forms or analytics scripts.
External sources
Official source links lead to government websites with their own privacy practices. Opening those links is optional and is not required to run the calculator.
Reloading the page or changing states resets the form. Review date: October 23, 2026.
