(need suggestions )Tax saving on a 50 lac tax lability !

FY 2021-22 is going to end . I am freelancer in digital marketing(working on my own) online , My local CA does not help much on tax saving or tax planning , so I am putting it here . my tax liability is around 50-55 Lacs this year , only 20-30 days left . 

If I invest or buy a new business entity for betterment of my current business , will it save me some tax this year ?

or suggestions ? I would like to pay for your consultation if you are interested to help me in this regard .
