How to Reach Us
The fastest way to reach the team is email: [email protected]. We welcome tool feedback, data corrections, content suggestions, and bug reports — if a number looks wrong, it deserves a second look, and we want to know.
You can write in English or Chinese, whichever is more comfortable; both are read by the same small team. After you write, your message goes into a shared queue that we triage together, so there is no need to send duplicates.
If your question concerns a saved record or an exported JSON file, you may attach it — remember that your files never leave your machine during normal use, and we only ever receive what you deliberately choose to send.
What to Include
For bug reports, the most helpful details are the page URL, the values you entered (a screenshot is perfect), the result you expected, and what the calculator showed instead. Your browser and device type — for example, Safari on iPhone or Chrome on Windows — help us reproduce display issues quickly.
For data corrections, please point us to the IRS or SSA source you are comparing against. A Revenue Procedure number, an IRS.gov page, or an SSA announcement lets us verify the figure and ship a fix without a long back-and-forth.
What We Can and Cannot Answer
We can answer questions about how the calculators work, where a figure comes from, and why a page says what it says.
We cannot provide individual tax advice. We are not CPAs, Enrolled Agents, or attorneys, and we cannot prepare or review your return, comment on your specific situation, or tell you what to claim. For personal tax decisions, please consult a qualified CPA or EA, or use the free resources at IRS.gov.
If your question is about your own return — whether you should itemize, how to report a specific 1099, or how a life event changes your filing status — a professional who can see your full picture will always give you a better answer than a web tool's support inbox can.
Response Time
We are a small team and we read every message. Most emails receive a reply within two to three business days; during the January–April filing season it can take a little longer. Messages reporting an incorrect figure that other visitors rely on are always prioritized.
We do not offer phone support at this time — email keeps a written record that makes it far easier for us to track, reproduce, and confirm every fix.
