Real tax rate

Summary
If you make 378,718,080 円 a year living in Japan, you will be taxed 170,548,850 円. That means that your net pay will be 208,169,230 円 per year, or 17,347,436 円 per month. Your average tax rate is 45.0% 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 46.10 円, hence, your net pay will only increase by 53.90 円.
