Did you know your employer also pays tax on your salary? It costs the employer 45,527 円 to pay you 310,024 円. In other words, every time you spend 10 円 of your hard-earned money, 3.51 円 goes to the government.
Real tax rate
30.6%
So, with you and the employer both paying tax, what used to be a 20.4% tax rate now rises to 30.6%, meaning your real tax rate is actually 10.2% higher than what it seemed at first.
Summary
If you make 3,720,288 円 a year living in Japan, you will be taxed 760,680 円. That means that your net pay will be 2,959,608 円 per year, or 246,634 円 per month. Your average tax rate is 20.5% and your marginal tax rate is 28.9%. 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 28.90 円, hence, your net pay will only increase by 71.10 円.
Bonus Example
A 1,000 円 bonus will generate an extra 711 円 of net incomes. A 5,000 円 bonus will generate an extra 3,555 円 of net incomes.
