I have a company set up with a schedule C and a schedule E. I have another rental I would like to have in it in anther schedule E but there is no place to add another one. Do I have to make another company just for it?
You don't have to get another company, Butchde3. Let me explain how it works.
In QuickBooks Online, you'll have to organize your accounts to match the Schedule C and E. The Profit and Loss report will make it easy to transfer numbers.
With regards to another Schedule E, you can set up each property as a customer. Each building can be set up as a sub-customer. You can also utilize the Class tracking feature. This way, when you pull up the Profit and Loss by Class report, it'll help you prepare the Schedule E columns.
