Aap log ITR fill khud se karte ho ya kisi se karwate ho toh kitne rupay charge karta hai vo ?

Khud se. Never gave money to CAs etc. Though that also means that you end up paying more taxes by paying whatever Govt asks you to.

If you are filing ITR 1 or ITR 2, there are so many videos that explain step by step on how to fill it. Please done waste money on hiring somebody to do it.

ITR 1 simplest. any layman can do it.

I have always done it by myself. Even if you don't know, you can refer to the online trusted sources. It's basic finance which everyone should know.
