Thank you for posting here in the Community, @dodger.
It's my pleasure to walk you through the step by step instructions on how to change the fiscal year in QuickBooks.
Go to Company, select My Company.
In the COMPANY INFORMATION box, hit the Pencil icon.
Choose the Report Information tab.
Change the Fiscal Year and Income Tax Form Used.
Once done, you can check any reports to verify if the updated fiscal date will appear and correct. You also have an option to customize report because columns and filters differ for each report/group of reports.
Please check this article to know more about the important task that needs to complete for the upcoming year-end:QuickBooks year-end guide.
