Did you know your employer also pays tax on your salary? It costs the employer 601 円 to pay you 4,095 円. In other words, every time you spend 10 円 of your hard-earned money, 3.34 円 goes to the government.
Real tax rate
29.1%
So, with you and the employer both paying tax, what used to be a 18.7% tax rate now rises to 29.1%, meaning your real tax rate is actually 10.4% higher than what it seemed at first.
Summary
If you make 49,140 円 a year living in Japan, you will be taxed 9,210 円. That means that your net pay will be 39,930 円 per year, or 3,328 円 per month. Your average tax rate is 18.7% and your marginal tax rate is 18.7%. 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 18.74 円, hence, your net pay will only increase by 81.26 円.
Bonus Example
A 1,000 円 bonus will generate an extra 813 円 of net incomes. A 5,000 円 bonus will generate an extra 4,063 円 of net incomes.
