About the ITR Filing category

Ask away your queries on Income Tax Return filing, e-Verify, Belated/ Revised return etc

Last year I filed ITR3 under the old tax regime. This year I would like to continue the same regime. Is it necessary to submit online form 10IEA. I read many articles which say that it is mandatory for “profession or business” for those opting in and opting out of the new tax regime which is the default scheme. Reading between the lines I understand that I have to submit. Am I right or wrong?
