About Impucalc
Impucalc brings together 126 calculators for 43 countries. Its purpose is to help you understand taxes, salaries and everyday transactions by showing how each amount is calculated.
Who runs the project
Gonzalo Caballero is responsible for Impucalc. You can contact info@impucalc.com to report an error, a changed reference or a usability problem. Operator details appear in the legal notice.
How calculators are prepared
Each tool identifies its official references, review date and supported scenarios. Formulas are checked against examples, limits and specific cases. Where references disagree, the tool explains the difference that affects the result.
Read our sources and review methodology to understand what a review date means and how changing data is handled.
What the result represents
A tool calculates the scenario represented by its inputs. Local rates, personal circumstances and unsupported transactions can require more information. A result is not an official assessment or a tax return filed with an authority.
Privacy and access
You do not need an account. Calculations run in your browser, and calculators work without accepting analytics or advertising. Read the privacy policy for details.

Editorial responsibility and limits
Guides explain specific decisions: which base to enter, when a special rate needs confirmation and which amounts are excluded from a result. Responsibility for the project does not imply professional accreditation in every jurisdiction covered. Impucalc does not present itself as a tax authority or provide individual tax advice.
Content is maintained alongside the formulas so a correction can be reviewed. A new editorial date identifies the check of that content; it does not certify every tax regime in a country. If you find a discrepancy, see how to report a correction.
