Deffered Tax is the amount the payment of which you delayed 
to pay in future. There are many reasons for deffered 
taxation. There are so many expanses and incomes which are 
not allowed by taxation department of Government but we 
enter as income and expenses in our financial statements 
because in accounting they are allowed as income or expense 
and that's why in the end the net income calculated by 
company and tax department is rearely reconsile due to 
problems mentioned above and due to that tax calculated by 
company is different the tax calculated by tax departments 
that's why deffered taxation is use to adjust tax between 
entity and tax department.
