Sizing tips

Default height="700" works for most layouts. On narrow columns (under 600px), increase to height="1100" since inputs and results stack vertically. The widget sends a postMessage with its actual height if you want to auto-resize.

Quarterly Tax Deadline Dashboard

Live countdown timer to the next IRS quarterly deadline, all 2026 dates at a glance, a penalty estimator, and direct IRS payment links. Updates every second.

Sizing tips

Default height="900" includes the penalty calculator and payment links. If you only want the countdown, you can set height="400" and the rest scrolls internally.

The calculator runs in their browser. No data is collected. No cookies set. No performance impact on your site.

Questions

Is this really free? What's the catch?

Completely free, no catch. The widget includes a small "Powered by ceocult" link at the bottom, which helps people discover our other free tax tools. That's the entire business model: useful tools that spread through embeds. We don't run ads inside the widget, we don't collect your visitors' data, and we don't charge for usage.

Does this work with WordPress?

Yes. In the WordPress editor, add a "Custom HTML" block and paste the iframe code. It works in both the classic editor and Gutenberg. If you use Elementor, use an HTML widget. For WPBakery, use a Raw HTML element.

Will this slow down my website?

No. The iframe loads asynchronously and doesn't block your page. All calculations happen in the visitor's browser with zero server calls. The total widget payload is under 15KB (smaller than most images).

Do you collect any data from my visitors?

No. Zero data leaves the browser. No cookies, no analytics pixels, no tracking scripts. All calculations run 100% client-side. We literally cannot see what your visitors enter.

Can I customize the appearance?

The widgets use a clean, neutral design that works on most sites. If you need brand-matched styling, reach out via our About page and we can discuss custom embed options for high-traffic sites.

Are the tax calculations accurate?

The calculators use 2026 projected federal tax brackets and simplified state rates. They provide estimates for educational purposes and should not replace professional tax advice. We verify rates quarterly and display a freshness indicator.
