Change of address within a jurisdiction does not change the TAN. However, it may involve a change in the Assessing Officer. Such changes must, therefore, be intimated to ITD so that the TAN database of ITD can be updated. In case of change of address from one jurisdiction to another (e.g. address changes from Bangalore to Mumbai), a new TAN needs to be applied for and previous TAN needs to be surrendered on allotment of fresh TAN.
