Tax cutting

Opt for section 44ad and pay income-tax on 8% of 9100000

If incentive is in the form of commission then you are out from 44AD presumptive Taxation.

Under 44AD, if applicable then minimum of 8% or 6% of profit on turnover OR actual profit whichever is higher ought to be declared.

Under regular business income you can declare even below 8% or 6% without tax audit.

Can I make it 6% by auditing?

First let know what is 100000/- ? is it Commission or what ??
