Jairo Tunisse

What he is responsible for

• Building the calculators: the formulas, the code that runs them and the tests that check them.
• Choosing the sources behind every rate, bracket and table, and citing them on each page.
• Updating calculator data when tax tables and other sources change, and reviewing guides before they are marked published.
• Reading correction reports sent through the contact form and fixing confirmed errors.

How that process works is described in our editorial policy, and the formulas and data behind each result are on the methodology page.
