Tax Planning for Private Companies

Hii Professionals,

Please help me with the tax planning of private companies.

A private company has 2 directors and these 2 directors are also the shareholders of the company.

We need to pay both these directors a sum of 20 lacs annually to each of them.
Please suggest some way so that tax liability is minimum to both of them because if we pay whole 20 lacs as a salary then they would have to pay a hefty amount of tax.

thanks in advance
