S Corp 1120S in multiple states

[khassy]

If an S Corp has a part year business in both NY and CA what needs to be done regarding 1120S filing?

If you are using TurboTax Business, see the following:

You will most likely need to file returns in both states.

Hi thank you for the quick reply 🙂  I don't need to see a list of forms availability though.  I was wondering how exactly to determine whether an 1120S needs to be filed in both states and what considerations I need to be aware of and pay attention to.  Thank you again.
