Partnership to proprietorship firm

1. Existing VAT registration is not valid due to change of constitution, you need to obtain new one and surrender the old
2. Existing PAN is also not valid and hence surrender, the PAN card of the proprietor to be used for the purpose of proprietorship concern
3. If the firm is registered, then dissolution also to be registered (welcome views of others)
4. Firm PAN can be used for filing return of income till the date of dissolution and thereafter PAN of proprietor is relevant

Thank you for the suggesstion

1. Can i use DVAT 07 part B for deletion of partners, as i want to use the same VAT number.

4. So i need to fill in the returns with the PAN card of the firm till the operations are continued.

Later on, what has to be done with the Income tax id with the firm PAN card.

If, later on PAN of proprieter is valid, then do i need to file the returns of the firm while filing my own taxes.

Thanks

Manish
