Did't know where to ask this at. I have been on hold with irs for some time.

I am doing some estate planning for myself. I am adding a my son to my business as

an owner on my S Corp. I know I have to have  him approved since he will now have some ownership in the business . I did not see where I can add him or update the application and go the approval process. I have had my efin for years. Do you  know if I have to do a whole new application. and hopefully this will not effect my continuing to file returns while he is being approved.

Thx

Michele
