The short version: we don't want your data, we don't ask for an account, and your income, withholding, and quarterly payments never leave your device. Use this page like you would a paper worksheet.
Anonymous, cookieless usage analytics. We use Cloudflare Web Analytics — a privacy-first tool that measures aggregate page views, page performance, browser type, and approximate country (from IP, not stored). It sets no cookies, doesn't track you across sites, and is never tied to any individual. Because it's cookieless it runs for all visitors and needs no consent.
This site is free because it's supported by display advertising. Our advertising partners may set their own cookies on your device to serve relevant ads and measure performance. We explicitly do not share any financial information you enter — including your income, withholding, or quarterly payments — with any advertising or analytics partner.
You choose what's allowed when you first arrive, and you can change it at any time — . You can also opt out of personalized advertising via aboutads.info or your browser's privacy controls.
California residents have the right to opt out of the "sale" of personal information. Under CCPA's broad definition, our use of behavioral advertising cookies may qualify. To opt out, use the cookie consent controls or enable the Global Privacy Control (GPC) signal in your browser — we honor GPC.
Because we don't store anything server-side, the only place your data exists is on your device. Clear your browser's site data for quarterlytaxplan.com to remove it.
This site is not directed to children under 13, and we do not knowingly collect any information from children.
Links to the IRS, EFTPS, state departments of revenue, and sibling calculators lead to their own websites; we don't control or speak for their privacy practices.
