About the school

Taught by someone who's actually done the hiring.

Most tax courses are written by people who have never run a tax office or hired a preparer in January. This one is different. It's the training our founder wishes every new hire had walked in with.

Founder & Instructor
The short version

Mario Costanz has spent his career building and running tax businesses, not writing about them from the outside. He founded Happy Tax, a national tax-preparation franchise, and grew it from a single office into a brand with locations across the country.

Along the way he hired and trained seasonal preparers and saw exactly where new people struggle and where they thrive. That hiring seat is the point of this school. He knows what an office actually needs a first-year preparer to be able to do in January.

He wrote Taxes Made Happy and Crypto Taxes Made Happy, two practical books drawn from the work of building tax businesses and preparing for new areas of client demand.

Free Tax School turns that experience into practical guidance for people considering the profession and for new preparers.
