TDS @ Higher rate of 20%

If tax at a higher rate of 20% was deducted on your dividends because your PAN wasn't provided to the company, you can indeed claim this TDS in your income tax return. The company must first update their records with your correct PAN and revise their TDS return. Once they issue a TDS certificate under your correct PAN, you can then file your return and claim the TDS against your tax liability.
