What we can help with

• Wrong number or stale tax figure — if a rate, bracket, or limit looks off, include the tax year and the IRS source you are comparing against. We take accuracy corrections seriously and will fix and re-verify within 24 hours.
• Calculator feedback— missing a scenario, a filing status, or a state? Tell us what you were trying to calculate and what the calculator got wrong or didn't support.
• General questions about the math— if you want to understand how a result was calculated, the Methodology page for each tool explains the formula step by step. If the methodology page doesn't answer your question, email us.
• Press or partnership inquiries — include a brief description of the opportunity and we will respond if it is a fit.

What we cannot help with

CalcSumly provides educational estimates, not tax advice. We cannot review your personal tax situation, tell you what to file, or give guidance specific to your return. For that, consult a licensed CPA or enrolled agent.
