On average in the 175 countries studied, businesses submit 35 pages of tax returns a year in order to comply with regulations, and it takes 332 hours per year to comply with all tax requirements. In Hungary, businesses submit 24 pages of tax returns ands spend 300 hours to comply with all tax requirements. (Világgazdaság)
