A person filed ITR4 from last few years as he had business. he also purchased mutual fund from where he got dividend and it also reflected in AIS report where he saw also purchase Mutual Fund. So now which return he should filed, ITR4 or ITR3, if he shown in other income as dividend as he did not sale any mutual fund till now and filed ITR4, there will be any problem or not? please give your valuable opinion.
