It is advantageous to show professional fees rather then show in other income
Firstly TDS is deducted u/s 194J.
If you take professional fees as other income than IT dept will ask you for further income shown in 26AS against 194J.
Even if TDS was not deducted it is advantageous.
Suppose you come under 20% bracket
Let us say your Professional fees is 1 Lakh plus salary.
Your presumtive income is 50k only while in other income you have to take full 1 lakh.
In ITR_4S you will be taxed on salary plus 50k and you can claim TDS u/s 194J.
In ITR-1 you will be taxed on salary plus 1 lakh and you cannot claim TDS u/s 194J more over you will get notice for filing wrong ITR
