Contact RefundPlot

The fastest way to reach RefundPlot is email: [email protected]. The inbox is read by the person who builds and maintains the calculators, not a support queue.

• Corrections. If a constant, bracket threshold, or formula looks wrong, include the IRS source (publication number or Rev. Proc.) and the page URL. Confirmed errors are fixed, credited in the methodology changelog, and the page is re-verified.
• Bug reports. Which calculator, what inputs, what you expected, and what you got. A saved snapshot URL reproduces the exact state — paste it straight in.
• Privacy questions. See the privacy policy first; most questions are answered there.

No accounts, no ticket numbers, no automated replies. Corrections with a primary source are typically handled within 48 hours — the same 48-hour IRS-update SLA we publish for tax-year constant changes.

Do not email tax documents, Social Security numbers, or any personal financial information. The calculators run entirely in your browser — we have no way to receive, store, or process your tax data, and we never want it. General questions about your own tax situation should go to a qualified tax professional who can see your full picture.
