Thank you for reaching out about changing the fiscal year in QuickBooks Self-Employed (QBSE). I'll provide more details below.
Currently, QBSE is configured to align your fiscal year with the calendar year, running from January 1 to December 31. Because of this configuration, QBSE doesn't allow you to modify or customize these dates.
QBSE is designed to simplify tax time by following the calendar year strictly. When you complete the Sales Tax setup, you won't need to specify a start or end date for the fiscal year, nor will you have to indicate a filing frequency, as these details are fixed.
If you need to use a different fiscal year, that option is available in QuickBooks Online. You can change your fiscal year start month there. If that sounds like something you need, check out our Plans & Pricing page to see which QuickBooks Online plan might work best for you.
