Contact
Corrections are the most useful thing you can send us. If a number looks wrong, tell us what you expected and we will trace it back to the source.
Write directly to contact@calcugrid.com, or use the form below — it opens your mail app with everything already filled in.
For corrections, include the page URL and your inputs. "The Georgia figure is wrong" takes far longer to investigate than "on /georgia/85000-salary-after-tax, single filer, I expected state tax of about $X because of [source]". With the second, we can usually confirm or fix it the same day.
Response times
This is a small project, not a support desk. Data corrections are prioritised and usually answered within a couple of days. Privacy and data requests are answered within one month, as required under the UK and EU GDPR — see the Privacy Policy for what we hold, which is very little.
What we cannot help with
We cannot advise on your personal tax position, review a return, or tell you what to claim. We are not tax preparers or advisers, and answering such questions would be exactly the professional advice our Disclaimer says this site does not provide. For that you need a qualified professional in your jurisdiction.
