As we have to file Return for FY 2015-16, before 31/3/18, I have an issue in TDS. While my TDS credit is matched with 26 AS credit in my name , I have not recd any TDS certificate from a nationalised bank for 2015-16. In spite of repeated follow up , Bank is not issuing or already issued and lost it. ITR requires Unique TDS certificate number to be mentioned. Now how to file the Return , in the absence of TDS cert no. Some body may pl clarify.
