Filing a T2 Tax Return and Schedule 104 without an accountant can seem challenging since the process and requirements can be somewhat complex and may require a detailed understanding of tax laws, financial documentation and CRA regulations.
While QuickBooks doesn't also directly support forms like Schedule 104, I recommend reaching out to your accountant to make sure your T2 filing complies with all legal obligations and confirm if your organization qualifies under CRA's rules.
To give you an overview of the process, you'll need to access tax returns in QuickBooks Online Accountant and export from QuickBooks Online to a GIFI file. From there, you can create a return (GIFI file), add a new form and file the return. I've added this article for your reference: Accountant T2 Corporate tax return in QuickBooks Online Accountant.
