I am filing a 7004 extension for my s-corp. I am confused on the amount I put for line 7 total payments. Since an s-corp is a pass through, does it make any tax payments

Enter zero's and send to IRS. 

Form 7004 Application for Automatic Extension of Time To File Certain Business Income Tax, Information, and Other Returns, is used for various income tax returns. Some of those returns are not pass through entities.
