can we change pan card signature

Yes, you can change your PAN card signature. The Income Tax Department allows updates by submitting an application for 'Changes or Correction in PAN Data.' You can complete this process online via the Protean e-Gov (formerly NSDL) or UTIITSL portals, or by submitting a physical form at a PAN service centre. The application requires selecting the "Signature Mismatch" option, providing a clear copy of your new signature, and submitting the necessary identity documents. A processing fee is applicable for the correction.
