At this time, QuickBooks only files payroll taxes. Meanwhile, you can use the data in QuickBooks Online to serve as your reference when filing their C Corp business taxes outside the program. I'd suggest consulting your accountant or tax adviser for further guidance.
If you don't have one, not to worry! I can help run a search to find an accountant. You can visit our ProAdvisor website to find an accountant or bookkeeper. They are a US-based team of certified tax professionals who can keep your books precise and up to date each month.
