India has over 3 crores tax payers who file the tax returns at the end of assessment year. After the Income Tax Department has implemented centralized processing of Income tax, all the tax payers now have to e-file their tax returns. In this online portal, the tax payers are asked to provide certain jurisdictional information while filing taxes. It is not mandatory for a tax payer to know the jurisdiction of their income tax, but it is advisable to be aware of this information in order to handle any kind of dispute that might arise in future regarding tax related issues. If this jurisdictional information is left blank, the system automatically will route the case to the Assessing Officer, based on the tax filer’s PAN card details.
