The typographical error in filling the fields of income tax return is very common.There are so many fields to be filled while filing tax return is natural. So , error in filling wrong provision of the Income Tax Act or some time because of ignorance of law , the tax payer claims the exemption under a wrong provision or section of the Income Tax Act. For example , may be inadvertently , a tax payer may write section 10(38) or even 10(36) for claiming exemption on capital gains on share when actually the fact relates to exemption under section 54 or 54F. So , if such error happens, can assessing officer stick to the point that since a wrong provision has been mentioned in the tax return , he /she will not allow the exemption. I don’t think so .
