Did you know your employer also pays tax on your salary? It costs the employer 153,937 円 to pay you 4,310,930 円. In other words, every time you spend 10 円 of your hard-earned money, 4.18 円 goes to the government.
Real tax rate
40.4%
So, with you and the employer both paying tax, what used to be a 38.2% tax rate now rises to 40.4%, meaning your real tax rate is actually 2.2% higher than what it seemed at first.
Summary
If you make 51,731,160 円 a year living in Japan, you will be taxed 19,784,451 円. That means that your net pay will be 31,946,709 円 per year, or 2,662,226 円 per month. Your average tax rate is 38.2% and your marginal tax rate is 46.1%. This marginal tax rate means that your immediate additional income will be taxed at this rate. For instance, an increase of 100 円 in your salary will be taxed 46.11 円, hence, your net pay will only increase by 53.89 円.
