Did you know your employer also pays tax on your salary? It costs the employer 6,244 円 to pay you 42,520 円. In other words, every time you spend 10 円 of your hard-earned money, 3.36 円 goes to the government.
Real tax rate
29.3%
So, with you and the employer both paying tax, what used to be a 18.9% tax rate now rises to 29.3%, meaning your real tax rate is actually 10.4% higher than what it seemed at first.
Summary
If you make 2,211,040 円 a year living in Japan, you will be taxed 417,481 円. That means that your net pay will be 1,793,559 円 per year, or 149,463 円 per month. Your average tax rate is 18.9% and your marginal tax rate is 20.9%. 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 20.85 円, hence, your net pay will only increase by 79.15 円.
Bonus Example
A 1,000 円 bonus will generate an extra 792 円 of net incomes. A 5,000 円 bonus will generate an extra 3,958 円 of net incomes.
