Is the taxes that have been added to me is legal?
When you are working on a company, there will be taxes that will be deducted to your salary every cut off of your pay. You should know that everyone in the world is paying taxes to contribute to the community. But I have realized that my salary is low that the usual pay. But I work my ass off to get the salary I deserve.
Singapore follows a progressive resident tax rate starting at 0% and ending at 22% above S$320,000. There is no capital gain or inheritance tax. Individuals are taxed only on the income earned in Singapore. The income earned by individuals while working overseas is not subject to taxation barring a few exceptions. If the company is not doing the right tax deduction you can report them to the IRAS.
