Built from tax-office operating and hiring experience.
Free Tax School brings Mario Costanz's experience building tax businesses, hiring preparers, and adopting new technology into practical career and practice guidance.
Mario Costanz has spent more than 20 years building and running tax businesses. He founded Happy Tax after developing hands-on tax-office experience and built a nationwide tax-preparation franchise.
He hired and trained seasonal preparers and saw where new people needed clearer instruction. That hiring experience shapes the career questions, operating examples, and practice-planning tools at Free Tax School.
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.
Two books about building a tax practice and working through cryptocurrency tax questions. Both earlier editions are available by email.
