 ### Taxation
 
-When money is withdrawn, tax is triggered. Taxes apply only to the profit/gain portion of the money withdrawn. For example, if the initial investment was 1000.00, the current balance is 1200.00, then the taxes will be applied to 16.67% = (200/1200) of the balance. Meaning that you should apply tax on 33.34 (200 x 16,67%).
