To change the name of your father to your husband’s name on your PAN card, you will need to follow these general steps:

1. Visit the Official Website: Go to the official website of the Income Tax Department of India for PAN card services. The official website is https://www.incometaxindiaefiling.gov.in.
2. Download the PAN Correction Form: Download the relevant form for making corrections in your PAN card details. The form you need is likely Form 49A if you are an individual.
3. Fill Out the Form: Fill in the required details in the correction form. You will need to provide your existing PAN details, the correct details (your husband’s name), and any supporting documents as required.
4. Attach Documents: You will likely need to provide supporting documents to verify the change you are making. These could include marriage certificates, identity proof of your husband, and any other documents as specified in the instructions.
5. Submit the Form: Submit the filled-out form along with the necessary documents to the designated PAN card office or authorized centers. You might also have the option to submit the form online, depending on the procedure followed by the Income Tax Department.
6. Pay Fees: There could be a processing fee associated with making corrections to your PAN card details. Ensure that you pay the applicable fees along with your application.
7. Verification and Processing: Your application will be reviewed by the Income Tax Department. They may verify the documents and details you have submitted.
8. Receive Updated PAN Card: Once your application is approved and processed, you will receive an updated PAN card with the corrected details (your husband’s name). The new PAN card will be sent to the address you provided in the application.

It’s important to note that procedures and requirements may vary, and the above steps are a general guideline based on the process as of my last knowledge update in September 2021.
