One of my friends earns 15k-20k/month by driving truck.
Truck which he is driving is belongs to him and his 3 brothers and they have total 2 trucks.
Suppose they all brothers earns total 40k/month from these 2 trucks and distribute this income amongs them.
From truck income my friend get share of 10k/month.
By combining both income of my friend his total income will become 25k-30k/ month.

My querry is that which itr should he file?..
Where he should show his income that he earns by driving truck as it is not salary?
And where should he show his truck income?
