Real tax rate
35.7%
So, with you and the employer both paying tax, what used to be a 34.8% tax rate now rises to 35.7%, meaning your real tax rate is actually 0.90000000000001% higher than what it seemed at first.
Summary
If you make $ 15,839,990 a year living in Taiwan, you will be taxed $ 5,518,511. That means that your net pay will be $ 10,321,479 per year, or $ 860,123 per month. Your average tax rate is 34.8% and your marginal tax rate is 40.0%. This marginal tax rate means that your immediate additional income will be taxed at this rate.
