Yes, you can file RTI to the income tax department but other than Pan Card number, details must be mentioned in the application. The application must be made to the concerned IT office where the husband was filing the IT. But there are chances that all the requested information might not be available with the Income tax office. The matter is related to multiple offices/ department. The application can be made to all the public authority to whom the matter is related.
