In addition to Hari, I suggest that the basic salary should be 50%-60% of the gross salary, but not less than the minimum wages of the state. The HRA should be 30%-40% of the basic salary. Conveyance allowance should be Rs. 800/- (any amount above that is taxable), and Medical Allowance should be Rs. 1250/- (any amount above that is taxable). The rest should be allocated to other allowance heads.
Thanks & Regards,
