My company has given an option to choose BASIC salary in the compensation plan. The BASIC SALARY can be chosen as 25% to 40% of the CTC. I stay in metro and am having 30 lacs CTC.  I pay a monthly rental of 45000/-. What is the optimum level of BASIC salary that I should choose in order to minimise tax . If I choose a higher Basic, then will it have any effect on other components like increased PF/ retirals? How will my take home salary and tax be affected> Pls guide.......
