Report a calculation or source problem

• The exact calculator page and the date you used it.
• The tax year, jurisdiction and rule you expected it to follow.
• Example inputs using made-up numbers, the displayed result, and your expected result.
• A link to the official rule or worked example if available.
• Your browser and device if an input, table or button does not work.

A reproducible example is more useful than a screenshot of a personal statement. For an account or benefit dispute, contact the plan administrator or responsible government agency rather than sending private documents here.

Privacy and accessibility questions

For a privacy request, describe which site feature or third-party service is involved. Calculator values stored on your device can be cleared in browser settings. The footer provides optional analytics settings and Google's regional advertising privacy controls. For an accessibility issue, describe the control, assistive technology and step that failed. No response time or resolution is guaranteed.

How corrections are handled

We reproduce an issue, compare the formula and scope with the applicable source, add a regression test where the result can be tested, and verify the corrected production page. An inquiry does not automatically change a result or establish that the current page is wrong. See our editorial and methodology policy for the limits of these tools.
