As you would all be aware that there would be many teachers, retired teachers and in some cases older students or home makers who would supplement income through tuition.

I just realized that many of them don't file IT for it.

In one such case, there was a home maker who used to give math tuition for 7-10 grade. There were 2 batches for each (weekend and weekdays): 1-1.5 hours (3 days or 2 days). Each batch had 4-6 students. The costs were from 500 to 1200 a month per student.

Thus if there were 5 students, 2 batches each, 4 grades (7,8,9,10) with a conservative average of 700 rupees a month:

This works out to 5*2*4*700 = 28,000 a month.

The overhead was nothing: old books, home as the center, white board and some regular ink supply.

If my understanding is correct, they would plug this in with the monthly financial requirements (groceries, transport, bills) the husbands salary is entirely saved and can be put for investment (in case of teachers, their school salary)

I've seen this being the case for so many years and so many times, it seems to be working like a well oiled machine with no one catching up or consequences!

How does this work out without the I-T department catching up on it? (i'm just curious as to how it works out)
