Real tax rate

So, with you and the employer both paying tax, what used to be a 45.5% tax rate now rises to 45.9%, meaning your real tax rate is actually 0.4% higher than what it seemed at first.
Summary
If you make 640,656,120 円 a year living in Japan, you will be taxed 291,321,054 円. That means that your net pay will be 349,335,066 円 per year, or 29,111,255 円 per month. Your average tax rate is 45.5% 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.
