Deloitte’s calculations are based on the average wages and salaries, and on the current tax regulations in the Visegrád Fours. Hungarians’ net income from a gross €500 would be at 72.4% and the Polish would get 70.67 % of it, while Czechs would keep 84.42% and Slovakians would keep the most of it: 85.65%. Net income is 57.2% of the gross income in Hungary, 68.35% in Poland, 78% in Slovakia and 79, 79% in the Czech Republic if calculations are based on €1000 gross income. Though there are similar social security liabilities in all the four countries, significant differences are apparent in a comparison owing to differing tax systems. (Gazdasági Rádió, Magyar Hirlap)
