The fastest way to reach the Calcotia team is by email:
It helps if you tell us which calculator and which country your message is about, and, for a correction, link the official source that shows the new rate or rule. We read every message and fix confirmed errors as quickly as we can.
Please note: we can explain how a calculator works, but we cannot give personal legal, tax or financial advice, and we cannot calculate an official figure for your individual case. For that, the official body in your country is the right place.
