Found a bug? Disagree with an assumption in one of the calculators? Want a tool we don't have yet?

Email us at [email protected] — we read everything and tool requests genuinely shape what we build next.

What to write about

The most useful emails fall into three buckets: corrections (a figure that looks wrong, a rule that changed, a broken assumption in a calculator), bugs (something that misbehaves in your browser), and requests (a tool you wish existed). Corrections get priority. Our correction policy: factual errors in tax figures are fixed within 48 hours, and the fix is noted with the page's new Updated date so you can see what changed and when.

What not to send

Please do not send personal tax documents, Social Security or National Insurance numbers, or anything else you would not want sitting in an inbox. We cannot give personal tax advice by email either — if your question is really what you should do about your own taxes, that is a conversation for a qualified CPA or Enrolled Agent, not for us.

When you will hear back

Every message is read by a human, and the aim is to reply within a week. Corrections and bug reports are usually acknowledged faster; longer discussions about feature requests may take the full seven days.

Other ways to reach us

Honestly, email is the only channel — this site has no phone line, no live chat, and no support ticket system, because a small independent project does not need them. If email is not an option for you, corrections can also start from the tools themselves: every calculator page links to its source note.

The About page lists the IRS and GOV.UK publications behind each formula; corrections based on those sources get priority over general feedback. For partnership, media, or advertising enquiries, use the same address with the subject line starting "Partnership" so it reaches the right inbox on the first pass.
