Every tax rate, threshold, and calculation displayed on this site is traced back to a specific IRS source listed at the bottom of the relevant article and on our Sources page. When tax rules change, affected articles are updated within 30 days and a dated "Last updated" note is added at the top.

Questions about our methodology or a specific calculation?
Email the FounderEvery article and calculator is written by a credentialed tax professional with specific expertise in the topic. Our writers hold CPA, EA, CFP, or LLM credentials and have years of hands-on experience with the IRS tax code. They research IRS publications, revenue rulings, and tax court cases to ensure accuracy.
A second credentialed professional independently reviews all content for factual accuracy, completeness, and compliance with current tax law. This reviewer checks every rate, threshold, and calculation against the most recent IRS publications and tax code sections. Any discrepancies are resolved before publication.
Tax laws change frequently — sometimes mid-year. We monitor IRS announcements, new legislation, and court decisions continuously. When rates, thresholds, or rules change, we update our calculators and articles within 48 hours and note the update date on every page so you always know how current the information is.
We cite the specific IRS publications, tax code sections, and revenue procedures that our calculations are based on. We also clearly state that our tools are for informational purposes and encourage users to consult a qualified tax professional for personalized advice. Honesty about limitations builds more trust than pretending to replace professional judgment.
