You have to file your return in ITR-2 if you do not have any income from business or profession.
Primarily it is applicable to those who do not involve in any business or profession and who can not file their return in ITR-1.
So you can file your return in ITR-2 when your total income is from other than ‘Business or Profession’
If your total income during the year includes from following sources, you are eligible to file your return in ITR-2.
You have to file ITR-2 in case where you are eligible to file ITR-1 as per the nature and quantity of income but you are a non-resident or resident but not ordinarily resident.
Hope this helps you.
