Fiscal Year Definition
A fiscal year is the 12-month period a business uses for accounting and financial reporting. It doesn't have to match the calendar year (January–December). Some businesses choose a fiscal year that aligns with their natural business cycle—like a retailer ending in January after the holiday season wraps up. The fiscal year determines when you close your books and file taxes.
Fiscal Year in Practice — Example
A summer camp company sets its fiscal year from October 1 to September 30. This makes sense because camp season runs May through August, and by September, all revenue is collected and expenses are settled. Closing the books in September gives them a clean picture of the season's performance. Their tax filing deadline is based on this fiscal year-end, not December 31.
Why Fiscal Year Matters for Your Books
Your fiscal year determines when your books open and close, when financial statements are prepared, and when taxes are due. Choosing the right fiscal year can make bookkeeping and tax planning significantly easier.
For seasonal businesses, a fiscal year that ends after the busy season makes reporting cleaner. You're not splitting your biggest revenue months across two reporting periods. It also gives your accountant a less-busy filing window, since most CPAs are slammed during traditional January–April tax season.
Once you choose a fiscal year, you generally need IRS approval to change it (Form 1128). So it's worth getting it right from the start. Most small businesses default to a calendar year, which works fine for non-seasonal operations.
How Fiscal Year Shows Up in QuickBooks
In QBO, set your fiscal year under the gear icon → Account and Settings → Advanced → Accounting → First month of fiscal year. QBO uses this setting to generate accurate year-over-year comparisons on the Profit & Loss and other reports. It also affects how Retained Earnings roll over on the Balance Sheet at year-end. If you change your fiscal year in QBO, update your tax settings to match.
Common Mistakes
FAQ
Q: Can a sole proprietor use a non-calendar fiscal year?
A: Generally no. The IRS requires sole proprietors to use a calendar year (January–December) unless they can demonstrate a valid business purpose for a different period.
Q: What's the difference between a fiscal year and a tax year?
A: They're usually the same. Your tax year is the 12-month period covered by your tax return, and it should match your fiscal year for consistency.
