Did you know your employer also pays tax on your salary? It costs the employer 54,840 円 to pay you 373,440 円. In other words, every time you spend 10 円 of your hard-earned money, 3.68 円 goes to the government.
Real tax rate
32.1%
So, with you and the employer both paying tax, what used to be a 22.1% tax rate now rises to 32.1%, meaning your real tax rate is actually 10% higher than what it seemed at first.
Summary
If you make 4,481,280 円 a year living in Japan, you will be taxed 991,063 円. That means that your net pay will be 3,490,217 円 per year, or 290,851 円 per month. Your average tax rate is 22.1% and your marginal tax rate is 31.9%. 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 31.86 円, hence, your net pay will only increase by 68.14 円.
Bonus Example
A 1,000 円 bonus will generate an extra 681 円 of net incomes. A 5,000 円 bonus will generate an extra 3,407 円 of net incomes.
