I filed an extension for myself and my wife but this year my business is incorporated and I can't figure out how to add in my EIN
To file an extension for a Corporation or S-Corp you must file a Form 7004. TurboTax Business on windows desktop is the product for you.
Here is a link to the IRS form, you can print and send in today.
